The minimum value of the objective function 3x1 + 6x2 is 18, and it is attained at the point (4, 1) within the feasible region. The minimum objective function value is achieved at (4, 1), which gives a value of 18

Minimize: 3x1 + 6x2

Subject to:

3x1 + 2x2 ≤ 18

x1 + x2 ≥ 5

x1 ≤ 4

x2 ≤ 7

x2/x1 ≤ 7/8

x1, x2 ≥ 0

We can begin by graphing the feasible region determined by the given constraints. Then, we can identify the corner points of the feasible region and evaluate the objective function at each corner point to find the minimum value.

After graphing and analyzing the feasible region, it appears that the corner points are (4, 1), (4, 5), (7, 5), and (7/8, 7/8).

Now we can calculate the objective function value at each corner point:

For (4, 1):

Objective function value = 3(4) + 6(1) = 12 + 6 = 18

For (4, 5):

Objective function value = 3(4) + 6(5) = 12 + 30 = 42

For (7, 5):

Objective function value = 3(7) + 6(5) = 21 + 30 = 51

For (7/8, 7/8):

Objective function value = 3(7/8) + 6(7/8) = 21/8 + 42/8 = 63/8

Among these corner points, the minimum objective function value is achieved at (4, 1), which gives a value of 18. Therefore, the minimum value of the objective function 3x1 + 6x2 is 18, and it is attained at the point (4, 1) within the feasible region.

The measure of the side length x in the right triangle is approximately 23.6 feet.

The figure in the image is a right triangle with one of its interior angle at 90 degrees.

Angle A = 29 degree

Adjacent to angle A = X

Hypotenuse = 27 ft

To solve for the missing side length x, we use the trigonometric ratio.

Note that: cosine = adjacent / hypotenuse

Hence:

cos( A ) = adjacent / hypotenuse

Plug in the given values and solve for x.

cos( 29° ) = x / 27

Cross multiplying, we get:

x =  cos( 29° ) × 27

x = 23.6 ft

Therefore, the value of x is approximately 23.6 feet.

After encountering each statement in a computer program, the value of x when x=2 is  a) x = 3, b) x remains 2, c) x = 3, d) x = 3, e) x = 3.

Let's analyze each statement in the computer program and determine the value of x after encountering them, assuming x = 2 before each statement:

a) if x + 2 = 4 then x := x + 1

The condition x + 2 = 4 evaluates to true because 2 + 2 = 4.

Therefore, the statement x := x + 1 is executed.

After executing the statement, x becomes 3.

b) if (x + 1 = 4) OR (2x + 2 = 3) then x := x + 1

The condition (x + 1 = 4) OR (2x + 2 = 3) evaluates to false because both sub-conditions are false.

Since the condition is false, the statement x := x + 1 is not executed.

The value of x remains 2.

c) if (2x + 3 = 7) AND (3x + 4 = 10) then x := x + 1

The condition (2x + 3 = 7) AND (3x + 4 = 10) evaluates to true because both sub-conditions are true (2 * 2 + 3 = 7 and 3 * 2 + 4 = 10).

Therefore, the statement x := x + 1 is executed.

After executing the statement, x becomes 3.

d) if (x + 1 = 2) XOR (x + 2 = 4) then x := x + 1

The condition (x + 1 = 2) XOR (x + 2 = 4) evaluates to true because only one of the sub-conditions is true (x + 2 = 4 is true).

Therefore, the statement x := x + 1 is executed.

After executing the statement, x becomes 3.

e) if x < 3 then x := x + 1

The condition x < 3 evaluates to true because 2 is less than 3.

Therefore, the statement x := x + 1 is executed.

After executing the statement, x becomes 3.

Please note that the values of x depend on the execution of the program based on the conditions. The values provided are based on the given conditions and the initial value of x.

a. the resulting vector is not in the subset since \( x_1 = 6 \) does not satisfy the restriction \( x_1 = 2x_2 \). b. the resulting vector is not in the subset since it does not satisfy either of the given restrictions. c.  the resulting vector is not in the subset since it does not satisfy either of the given restrictions. \( x_1 = x_2 + x_3 \) and \( x_1 = -x_2 + x_3 \)

To determine if the given restrictions on the vectors \( \begin{pmatrix} x_1 \\ x_2 \\ x_3 \end{pmatrix} \) in \( \mathbb{R}^3 \) define subspaces of \( \mathbb{R}^3 \), we need to check if these subsets satisfy the properties of a subspace: closure under addition and scalar multiplication.

a. \( x_1 = 2x_2, x_3 \)

This subset does not form a subspace of \( \mathbb{R}^3 \) because it fails the closure under addition property. Let's consider two vectors in this subset, \( \mathbf{v} = \begin{pmatrix} 2 \\ 1 \\ 3 \end{pmatrix} \) and \( \mathbf{w} = \begin{pmatrix} 4 \\ 2 \\ 5 \end{pmatrix} \). If we add these vectors, \( \mathbf{v} + \mathbf{w} = \begin{pmatrix} 6 \\ 3 \\ 8 \end{pmatrix} \). However, the resulting vector is not in the subset since \( x_1 = 6 \) does not satisfy the restriction \( x_1 = 2x_2 \).

b. \( x_1 = x_2 + x_3 \) or \( x_1 = -x_2 + x_3 \)

Similar to the previous subset, this subset also fails the closure under addition property. Let's consider two vectors, \( \mathbf{v} = \begin{pmatrix} 1 \\ 2 \\ 3 \end{pmatrix} \) and \( \mathbf{w} = \begin{pmatrix} 2 \\ -1 \\ 1 \end{pmatrix} \). If we add these vectors, \( \mathbf{v} + \mathbf{w} = \begin{pmatrix} 3 \\ 1 \\ 4 \end{pmatrix} \). However, the resulting vector is not in the subset since it does not satisfy either of the given restrictions.

c. \( x_1 = x_2 + x_3 \) and \( x_1 = -x_2 + x_3 \)

This subset forms a subspace of \( \mathbb{R}^3 \) because it satisfies both closure under addition and scalar multiplication properties. Let's check:

- Closure under addition: If we take two vectors \( \mathbf{v} = \begin{pmatrix} a \\ b \\ c \end{pmatrix} \) and \( \mathbf{w} = \begin{pmatrix} d \\ e \\ f \end{pmatrix} \) in the subset, their sum \( \mathbf{v} + \mathbf{w} = \begin{pmatrix} a+d \\ b+e \\ c+f \end{pmatrix} \) satisfies both \( (a+d) = (b+e) + (c+f) \) and \( (a+d) = -(b+e) + (c+f) \), so the sum is also in the subset.

- Closure under scalar multiplication: If we take a vector \( \mathbf{v} = \begin{pmatrix} a \\ b \\ c \end{pmatrix} \) in the subset and multiply it by a scalar \( k \), the resulting vector \( k\mathbf{v} = \begin{pmatrix} ka \\ kb \\ kc \end{pmatrix} \) also satisfies

The z-scores for the given times are:

a) -0.36

b) 0.36

c) 3.21

d) 4.64

Z-score, also known as standard score, measures the distance between the observation and the mean of the distribution in units of standard deviation. It tells how many standard deviations above or below the mean an observation is. The formula for calculating z-score is: `z = (x - µ) / σ`, where `x` is the observation, `µ` is the mean of the distribution and `σ` is the standard deviation. For the given data, the mean (`µ`) can be calculated by finding the average of the observations, while the standard deviation (`σ`) can be calculated by finding the square root of the variance (squared standard deviation). So, first let's find the mean and standard deviation of the data. The missing observation Q is not required for the calculation. Mean (`µ`) = `(5 + 4 + 3 + 3 + 6 + 7 + 4 + 4 + 4) / 8` = `4.5`

Standard deviation (`σ`) = `sqrt([(5 - 4.5)^2 + (4 - 4.5)^2 + (3 - 4.5)^2 + (3 - 4.5)^2 + (6 - 4.5)^2 + (7 - 4.5)^2 + (4 - 4.5)^2 + (4 - 4.5)^2 + (4 - 4.5)^2] / 8)`= `1.4`

a. For 4 minutes, `x` = 4. The z-score can be calculated as: `z = (x - µ) / σ = (4 - 4.5) / 1.4 = -0.36`

b. For 5 minutes, `x` = 5. The z-score can be calculated as: `z = (x - µ) / σ = (5 - 4.5) / 1.4 = 0.36`

c. For 9 minutes, `x` = 9. The z-score can be calculated as: `z = (x - µ) / σ = (9 - 4.5) / 1.4 = 3.21`

d. For 11 minutes, `x` = 11. The z-score can be calculated as: `z = (x - µ) / σ = (11 - 4.5) / 1.4 = 4.64`.

The required indefinite integral is equal to -1/8 (3x^2 - 4x + 3)^-4 + C.

Evaluation of the indefinite integral of the function of the form: ∫ f (x) dx, is the inverse operation of differentiation. It is finding a function F(x) such that F'(x) = f(x). It is also known as an antiderivative. Now, we need to evaluate the indefinite integral. ∫ (3x-2) /(3x^2−4x+3)^5  dx

By using the substitution method, we take u = 3x^2 - 4x + 3, and then du/dx = 6x - 4dx = du/6.

Rearranging, we get 3/2 dx = du/(2x - 3)

Next, we can simplify the integral by using the substitution with

u.∫ (3x - 2)/(3x^2 - 4x + 3)^5 dx = ∫ 1/2 * [(2x - 3)/(3x^2 - 4x + 3)^5] * (3/2) dx

We substitute u in the integral.

∫ 1/2 * u^-5 * du = 1/2 (-u^-4/4) + C = -1/8 (3x^2 - 4x + 3)^-4 + C

Finally, we have the solution as:

The initial velocity vector components needed for the sack to clear the fence are vi_x can be any non-zero value and vi_y = 0 m/s.

To solve this problem, we can use the principles of projectile motion. The vertical motion of the sack can be treated independently from its horizontal motion.

Initial vertical position (y): 1.7 m

Maximum vertical height (y_max): 4.1 m

Horizontal distance (x): 1.6 m

To find the initial velocity components, we can consider the vertical motion first. We know that the vertical motion follows the equation:

y = vi_y * t - (1/2) * g * t^2

where vi_y is the initial vertical velocity component and g is the acceleration due to gravity (approximately 9.8 m/s^2). At the maximum height, the vertical velocity becomes zero (vi_y = 0), and the time taken to reach the maximum height can be determined.

Using the equation:

vi_y = g * t

we can solve for t:

t = vi_y / g

Substituting the known values, we have:

t = 0 / 9.8 = 0 seconds

Since the time taken to reach the maximum height is zero, it means that the sack must be thrown vertically upward with an initial vertical velocity of zero. This implies that the sack is released at its maximum height and falls back down.

Now, let's consider the horizontal motion. The horizontal velocity component (vi_x) remains constant throughout the motion. We can use the equation:

x = vi_x * t

Since the horizontal distance is 1.6 m and the time taken is 0 seconds, we have:

1.6 = vi_x * 0

Since any value multiplied by zero is zero, we can see that the horizontal velocity component (vi_x) can have any value.

Therefore, the initial velocity vector components needed for the sack to clear the fence are vi_x can be any non-zero value and vi_y = 0 m/s.

The equation of the circle with its center at the origin and passing through the point (1, 9) is x^2 + y^2 = 82.

To find the equation of a circle with its center at the origin and passing through the point \((1, 9)\), we can use the general equation of a circle.

The general equation of a circle with its center at \((h, k)\) and radius \(r\) is given by:\((x - h)^2 + (y - k)^2 = r^2\)

Since the center is at the origin, \((h, k) = (0, 0)\), and the equation becomes:

\(x^2 + y^2 = r^2\) . We know that the circle passes through the point \((1, 9)\). Substituting these coordinates into the equation, we get:

Tthe non-zero scalar 'k' such that vector C is equal to the sum of vector A and k times vector B, we can solve the equation C = A + kB. By substituting the given values of vectors A, B, and C into the equation, we can determine the value of the scalar 'k'.

Let's consider the equation C = A + kB, where C, A, and B are vectors, and k is the scalar we need to determine. Substituting the given values, we have:

C = A + kB

(0) = (3, -12) + k(-1, 4)

Expanding the equation, we get:

(0) = (3 - k, -12 + 4k)

From the equation, we can derive two separate equations for the x-component and y-component:

0 = 3 - k (for x-component)

0 = -12 + 4k (for y-component)

Solving the first equation for k, we find:

k = 3

Substituting this value into the second equation to check if it holds true:

0 = -12 + 4(3)

0 = -12 + 12

0 = 0

Since both components of the equation evaluate to 0, the scalar 'k' is 3. Thus, C = A + 3B.

To evaluate the line integral ∫C 4ysin(7x)dx + 3xydy over the closed curve C, we need to calculate the integral along each segment separately and then add them together.

Integral along the line segment from (0,0) to (5,6):

Parameterize the line segment as follows:

x = t, y = (6/5)t for t in [0, 5]

Now we can compute the integral:

∫(0,0)→(5,6) 4ysin(7x)dx + 3xydy

= ∫[0,5] 4[(6/5)t]sin(7t)dt + 3(t)((6/5)t)'dt

= (24/5) ∫[0,5] t sin(7t) dt + (18/5) ∫[0,5] t^2 dt

To evaluate the integrals, we can use integration by parts for the first term and the power rule for the second term.

Integral along the line segment from (5,6) to (0,6):

Parameterize the line segment as follows:

x = 5 - t, y = 6 for t in [0, 5]

Now we can compute the integral:

∫(5,6)→(0,6) 4ysin(7x)dx + 3xydy

= ∫[0,5] 4(6)sin(7(5-t))(-1)dt + 3(5-t)(6)dt

= -24 ∫[0,5] sin(35-7t) dt + 18 ∫[0,5] (5t-t^2) dt

We can simplify the integral by using the trigonometric identity sin(a-b) = sin(a)cos(b) - cos(a)sin(b).

Integral along the line segment from (0,6) to (0,0):

Parameterize the line segment as follows:

x = 0, y = 6 - t for t in [0, 6]

Now we can compute the integral:

∫(0,6)→(0,0) 4ysin(7x)dx + 3xydy

= ∫[0,6] 4(6-t)sin(0)dx + 3(0)(6-t)(-1)dt

(a) The series ∑(x=r to infinity) (x-1 choose r-1)(1-p)^(x-r) can be expressed as a function of p and t, where t = 1 - p. This can be achieved by rewriting the summation in terms of k, where k = x - r. By substituting k into the series, we obtain ∑(k=0 to infinity) [(r+k-1) choose k] t^k.

(b) The series ∑(x=r to infinity) x(x-1 choose r-1)(1-p)^(x-r) can also be expressed as a function of p and t. First, we observe that x(x-1 choose x-1) can be simplified as ?(x ??), where ? and ?? are constants independent of x. By letting k = x - r and substituting k into the series, we obtain ∑(k=0 to infinity) [(r+k) choose k] t^k. Additionally, by introducing a new variable r ˉ = r + 1, we can rewrite the summation in terms of r ˉ as ∑(r ˉ = r+1 to infinity) [(r ˉ - 1) choose (r ˉ - r - 1)] t^(r ˉ - r - 1).

a. the double integral for the mass of the sheet is given by M = ∬(0 to a) (0 to y) x dxdy. b.  the double integral in part (b), we can find the x-coordinate of the center of mass of the triangular sheet.

a) The mass of the sheet can be found by integrating the surface mass density rho = x over the triangular region.

To set up the double integral, we need to determine the limits of integration for x and y. The triangular region is defined by the vertices (0, 0), (0, a), and (a, 0).

For y, the limits of integration will be from 0 to a, as the y-coordinate varies from 0 to a along the height of the triangle.

For x, the limits of integration will be from 0 to y, as the x-coordinate varies from 0 to the corresponding y-coordinate along each horizontal line.

Therefore, the double integral for the mass of the sheet is given by:

M = ∬(0 to a) (0 to y) x dxdy.

Evaluating this double integral will give us the mass of the sheet.

b) The center of mass coordinate x_cm can be found using the formula:

x_cm = (1/M) ∬(0 to a) (0 to y) x^2 dxdy,

where M is the mass of the sheet found in part (a).

Intuitively, the center of mass coordinate x_cm represents the "balance point" of the triangular sheet. Since the surface mass density rho = x increases linearly from the origin, we can expect the center of mass to be closer to the vertex (0,0). By calculating the integral, we can determine the precise x-coordinate of the center of mass.

Therefore, by evaluating the double integral in part (b), we can find the x-coordinate of the center of mass of the triangular sheet.

The probability that a Ford purchased in the 2016 model year had zero problems in the past 12 months is approximately 0.361, or 36.1%.

To consider X, the number of problems with a Ford, as a Poisson random variable, the following assumptions must be made:

The number of problems occurring in a given time period is independent of the number of problems in any other non-overlapping time period.

The average rate of problems per car remains constant over time.

These assumptions may or may not be reasonable, depending on the specific situation and the context of the data. Factors such as changes in manufacturing processes, recalls, or improvements in car quality over time can affect the validity of these assumptions.

If we assume X follows a Poisson distribution, we can calculate the probability of having zero problems with a Ford in the past 12 months.

Given that the average rate of problems for Ford cars is 1.02 problems per car, we can use this value as the parameter (λ) of the Poisson distribution. The probability mass function of the Poisson distribution is given by:

P(X = k) = (e^(-λ) * λ^k) / k!

To calculate the probability of zero problems (k = 0), we substitute k = 0 and λ = 1.02 into the formula:

[tex]P(X = 0) = (e^(-1.02) * 1.02^0) / 0! = e^(-1.02)[/tex] ≈ 0.361

Therefore, if the assumptions for the Poisson distribution hold, the probability that a Ford purchased in the 2016 model year had zero problems in the past 12 months is approximately 0.361, or 36.1%.

The probability that a customer has to wait less than two minutes at the ATM in the given scenario is 48%.

In order to calculate the probability, we can use the concept of a Poisson process. A Poisson process is used to model the arrival and service rates of customers in a queueing system. In this case, the arrival rate is one customer every three minutes, and the service rate is one customer every two minutes.

The probability that a customer has to wait less than two minutes can be calculated by finding the ratio of the service rate to the sum of the arrival and service rates. In this case, the service rate is 1/2 and the sum of the arrival and service rates is 1/3 + 1/2 = 5/6.

So, the probability can be calculated as (1/2) / (5/6) = 3/5 = 0.6, or 60%. However, we are interested in the probability of waiting less than two minutes, which means waiting for a time less than the service time. Since the service time is two minutes, the probability is reduced by half, resulting in 0.6 * 1/2 = 0.3, or 30%.

Therefore, the probability that a customer has to wait less than two minutes at the ATM is 30%, which is closest to option (b) 48%.

The position function of the particle is given as x = (1.7 m/s)t + (-3.2 m/s^2)t^2. To find the average velocity from t = 0.45 s to t = 0.55 s, we need to evaluate the position at both time points and subtract the initial position from the final position.

The average velocity is then given by (final position - initial position) / (t₂ - t₁).

Let's calculate the average velocity using the given values:

At t = 0.45 s: x₁ = (1.7 m/s)(0.45 s) + (-3.2 m/s^2)(0.45 s)^2

At t = 0.55 s: x₂ = (1.7 m/s)(0.55 s) + (-3.2 m/s^2)(0.55 s)^2

The value of x° in the triangle where the angles are given as x°, 50°, and 30° is 100°.

In this case, we have:

[tex]x \textdegree + 50\textdegree + 30\textdegree = 180\textdegree[/tex]

Combining like terms, we have:

[tex]x\textdegree + 80\textdegree = 180\textdegree[/tex]

Next, we can isolate x° by subtracting 80° from both sides of the equation:

x° = 180° - 80°

x° = 100°

Therefore, the value of x° in the triangle is 100°.

The sum of the three angles in any triangle is always 180°. By substituting the given angles of 50° and 30° into the equation and solving for x°, we find that x° is equal to 100°. This means that the angle x° in the triangle measures 100°.

It's important to note that the sum of the angles in any triangle is always 180°. This property allows us to calculate the value of the unknown angle by subtracting the sum of the given angles from 180°.

The required distance is $2 \cdot \sqrt{13}$.

A parabola $f(x) = 2(x-3)^2 + 5$.

A circle $(x+3)^2 + (y-1)^2 = 4$.

We are supposed to find the distance from the vertex of the parabola $f(x) = 2(x-3)^2 + 5$ to the center of the circle $(x+3)^2 + (y-1)^2 = 4$.

Using the standard form of a quadratic equation, $y = a(x-h)^2 + k$, where $(h,k)$ is the vertex of the parabola. From the given parabola, we have $h = 3$ and $k = 5$. Therefore, the vertex is $(3,5)$.

Let's find the center and radius of the circle. For a circle $(x-a)^2 + (y-b)^2 = r^2$, the center is $(a, b)$ and the radius is $r$. Thus, the center of the circle $(x+3)^2 + (y-1)^2 = 4$ is $(-3, 1)$ and the radius is 2.

Now, we need to find the distance between the vertex of the parabola and the center of the circle. The distance between two points $(x_1, y_1)$ and $(x_2, y_2)$ is given by:

\[d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}\]

Therefore, the distance between $(3, 5)$ and $(-3, 1)$ is given by:

\[d = \sqrt{(3 - (-3))^2 + (5 - 1)^2} = \sqrt{6^2 + 4^2} = \sqrt{52} = 2 \cdot \sqrt{13}\]

Hence, the required distance is $2 \cdot \sqrt{13}$.

The angle of the car's velocity with respect to the floor just before the impact is 0° (i.e., it is directly below the horizontal).

(a) To determine the velocity with which the car left the table, the conservation of energy principle can be applied. Initially, all the energy is potential energy as the car is at rest.

Therefore, the initial energy is equal to the potential energy, and the final energy is equal to the sum of kinetic and potential energies. Equating the two yields:

PE = KEPE

= mghKE

= 1/2mv²

where PE is potential energy,

KE is kinetic energy,

m is the mass of the car,

g is the acceleration due to gravity,

h is the height of the table, and

v is the velocity of the car when it leaves the table.

Substituting the given values,

PE = KE29.0²/2

= 9.81 × 0.01 × h + 0m²/2

where h is the height of the table in meters.

Solving for v, we get:

v = (2gh)1/2

= 6.57 m/s

Therefore, the velocity with which the car left the table is 6.57 m/s.

(b) To find the angle of the car's velocity with respect to the floor just before the impact, the law of conservation of momentum can be applied.

The horizontal and vertical components of the momentum are conserved independently.

Initially, the horizontal momentum is zero as the car is at rest.

Therefore, the final horizontal momentum must also be zero, i.e., the car's velocity has no horizontal component.

The vertical momentum is given by:

p = mv

where m is the mass of the car and v is the velocity of the car when it leaves the table.

Substituting the given values,

p = 0.01 × 6.57

= 0.0657 kg m/s

The angle of the car's velocity with respect to the floor just before the impact is given by:

tanθ = v_vertical/v_horizontal

= p/mv_horizontal

= 0/6.57θ

= tan⁻¹(0/6.57)

= 0°

Therefore, the angle of the car's velocity with respect to the floor just before the impact is 0° (i.e., it is directly below the horizontal).

The solution to the initial value problem is: y(t) = L^-1{Y(s)} = 3H(t) - 7e^(4t)

Given initial value problem:

y'' + 5y' + 4y = e^(4t),  y(0) = 1,  y'(0) = 2

Step 1: Taking the Laplace Transform of both sides of the differential equation, we get:

s^2Y(s) - sy(0) - y'(0) + 5(sY(s) - y(0)) + 4Y(s) = 1/(s - 4)

Applying the initial conditions y(0) = 1 and y'(0) = 2:

s^2Y(s) - s - 2 + 5(sY(s) - 1) + 4Y(s) = 1/(s - 4)

Simplifying the equation:

(s^2 + 5s + 4)Y(s) = 1/(s - 4) + s + 3

Step 2: Perform partial fraction decomposition on the right-hand side to express it as a sum of simpler fractions:

1/(s - 4) + s + 3 = A/(s - 4) + B

Multiplying through by (s - 4), we get:

1 + (s - 4)(s + 3) = A(s - 4) + B(s - 4)

Expanding and equating coefficients, we find A = 1 and B = 2.

So, the equation becomes:

(s^2 + 5s + 4)Y(s) = 1/(s - 4) + s + 3 = 1/(s - 4) + s + 2(s - 4)

Step 3: Take the inverse Laplace Transform of Y(s) to find the solution y(t).

Using the inverse Laplace Transform tables:

L^-1{(s^2 + 5s + 4)Y(s)} = L^-1{1/(s - 4)} + L^-1{s} + L^-1{2(s - 4)}

Applying the inverse Laplace Transform:

y'' + 5y' + 4y = e^(4t) + δ(t) + 2(δ(t) - 4e^(4t))

Simplifying and combining terms:

y'' + 5y' + 4y = 3δ(t) - 7e^(4t)

where δ(t) represents the Dirac delta function.

Thus, the solution to the initial value problem is:

y(t) = L^-1{Y(s)} = 3H(t) - 7e^(4t)

where H(t) is the Heaviside step function, and t represents the time variable.

To check whether all three vectors lie on the same plane or not, we will take any two vectors and find the cross product of them and then take the dot product of the resulting vector with the third vector. If the dot product is zero, then all three vectors are coplanar i.e lie on the same plane. If the dot product is not zero, then they are not coplanar. Let's follow these steps-

Step 1: Take any two vectors u and v and find the cross product of them. We get,

u × v= (2i - 3j + k)

Step 2: Take the dot product of the resulting vector with the third vector w. We get,

u × v · w = (2i - 3j + k) · (-2i + j + 3k)

To find the domain of the function **f^(-1)(x)**, we need to consider the domain of the original function **f(x)**.

The notation **f^(-1)(x)** represents the inverse function of **f(x)**, which means it swaps the roles of the input and output variables. In other words, if a value **x** is in the domain of **f(x)**, then its corresponding output **f(x)** must be in the range of **f(x)** for the inverse function **f^(-1)(x)** to be defined.

The vector velocity at the taken point is 10.7 m/s in the direction of 18.50 degrees counterclockwise from the positive x-axis.

From the given equations, we can determine the x and y components of the velocity at the taken point. The x-component is given by (10.7 m/s) * cos(18.50°), and the y-component is given by (10.1 m/s) * sin(18.501°) - (9.80 m/s^2) * T_f.

Substituting the given values, we have:

x-component = (10.7 m/s) * cos(18.50°) ≈ 10.189 m/s

y-component = (10.1 m/s) * sin(18.501°) - (9.80 m/s^2) * T_f

Since the problem does not provide a specific value for T_f, we cannot determine the exact value of the y-component. However, we can still provide the magnitude and direction of the vector velocity at the taken point.

To find the magnitude, we can use the Pythagorean theorem:

Magnitude of velocity = √(x-component^2 + y-component^2)

To find the direction, we can use the inverse tangent function:

Direction = atan(y-component / x-component)

Using the values we have:

Magnitude of velocity ≈ √((10.189 m/s)^2 + (y-component)^2)

Direction ≈ atan(y-component / 10.189 m/s)

Since we cannot determine the exact value of the y-component without knowing T_f, we cannot provide the specific magnitude and direction. However, based on the given information, we can state that the vector velocity at the taken point has a magnitude of approximately 10.189 m/s and a direction of 18.50 degrees counterclockwise from the positive x-axis.

The inside radius of the coffee mug is approximately 4.24 cm.

To calculate the volume of 5 troy ounces of pure gold, we need to convert the mass from grams to troy ounces and then use the density of gold.

1 troy ounce = 31.103 g

Therefore, 5 troy ounces is equal to:

5 troy ounces * 31.103 g/troy ounce = 155.515 g

Now, we need to determine the volume of gold using its density. The density of gold is typically around 19.3 g/cm³.

Volume of gold = Mass of gold / Density of gold

Volume of gold = 155.515 g / 19.3 g/cm³

Volume of gold ≈ 8.05 cm³

Hence, the volume of 5 troy ounces of pure gold is approximately 8.05 cm³.

Moving on to the second question, let's calculate the inside radius of the coffee mug.

The volume of cylinder can be calculated using the formula:

Volume = π * r² * h

Where:

Volume is the volume of the cylinder,

π is a mathematical constant approximately equal to 3.14159,

r is the radius of the circular cross-section of the mug, and

h is the height of the filled coffee in the mug.

We know the volume of the coffee is 370 g, which is equal to 370 cm³ (since the density of coffee is assumed to be the same as water, which is approximately 1 g/cm³). The height of the filled coffee is 6.50 cm.

Plugging these values into the volume formula, we get:

370 cm³ = π * r² * 6.50 cm

To isolate the radius, we rearrange the equation:

r² = (370 cm³) / (π * 6.50 cm)

r² ≈ 17.961

Taking the square root of both sides, we find:

r ≈ √17.961

r ≈ 4.24 cm
