The parameterization of the intersection of the paraboloid and the plane is: x = 2 cos t, y = 2 sin t + 2, z = 8 sin t + 8, where 0 ≤ t ≤ 2π.

a) Given, the cylinder equation as x² + y² = 9 and the plane equation as z = 2.

We can find the intersection between the cylinder and the plane by substituting z with 2 in the equation of cylinder. We get,

x² + y² = 9 ...(1)

This equation represents a circle with radius 3 and centered at the origin.

Thus, we can parameterize the circle as x = 3 cos t, y = 3 sin t and z = 2.

Hence, the parameterization of the intersection of the cylinder and the plane is:

x = 3 cos t, y = 3 sin t, z = 2, where 0 ≤ t ≤ 2π.

b) Given, the paraboloid equation as z = x² + y² and the plane equation as z = 4y.

We can find the intersection between the paraboloid and the plane by equating both the equations.

We get,

x² + y² = 4y ...(1)

This equation represents a circle with radius 2 and centered at (0, 2).

Thus, we can parameterize the circle as

x = 2 cos t,

y = 2 sin t + 2

and

z = 4(2 sin t + 2)

= 8 sin t + 8.

The approximate height of the Eiffel Tower at -9°C is approximately 0.191 meters.

Here, we have to calculate the approximate height of the Eiffel Tower at the lower temperature (-9°C), we need to consider the change in height due to the temperature change.

Given that the height increases by 19.1 cm when the temperature changes from -9°C to +40°C, we can use this information to find the height at -9°C.

Change in height = Height at +40°C - Height at -9°C

19.1 cm = Height at +40°C - Height at -9°C

Let's denote the height at -9°C as "h" meters.

The height at +40°C would then be "h + 0.191" meters (due to the 19.1 cm increase).

So, the equation becomes:

0.191 = h + 0.191 - h

Solving for "h":

h = 0.191

Therefore, the approximate height of the Eiffel Tower at -9°C is approximately 0.191 meters.

To prove that lim (n → ∞) |sn| = 0 implies lim (n → ∞) sn = 0, we will show that if the absolute value of a sequence converges to 0, then the sequence itself also converges to 0.

Let {sn} be a sequence such that lim (n → ∞) |sn| = 0. This means that for any ε > 0, there exists a positive integer N such that |sn| < ε for all n ≥ N. We want to show that lim (n → ∞) sn = 0.

Given ε > 0, we can choose the same N as before, such that |sn| < ε for all n ≥ N. Now, consider the difference between sn and 0, i.e., |sn - 0| = |sn|. Since |sn| < ε for all n ≥ N, it follows that |sn - 0| = |sn| < ε for all n ≥ N.

This shows that for any ε > 0, there exists a positive integer N such that |sn - 0| < ε for all n ≥ N, which is the definition of lim (n → ∞) sn = 0. Therefore, we have proven that if lim (n → ∞) |sn| = 0, then lim (n → ∞) sn = 0.

To calculate the p-value from the mean and standard deviation, you need to perform a statistical test, such as a t-test or z-test, depending on the sample size and whether the population standard deviation is known.

The p-value represents the probability of obtaining the observed sample mean or a more extreme value, assuming the null hypothesis is true. The p-value can be calculated using statistical software or by using the appropriate formula and a standard normal distribution table.

The calculation of the p-value depends on the specific statistical test being used. In general, for large sample sizes (typically greater than 30) or when the population standard deviation is known, a z-test can be used. For smaller sample sizes or when the population standard deviation is unknown, a t-test is more appropriate.

To calculate the p-value for a z-test, you would first calculate the test statistic, which is the standardized value of the sample mean using the formula:

z = (x - μ) / (σ / √n),

where x is the sample mean, μ is the population mean, σ is the population standard deviation, and n is the sample size. Then, you can look up the corresponding p-value from a standard normal distribution table or use statistical software to obtain the probability.

For a t-test, you would calculate the t-statistic using the formula:

t = (x - μ) / (s / √n),

where s is the sample standard deviation. The degrees of freedom for the t-distribution would depend on the sample size. Again, you can obtain the p-value by looking up the corresponding value from a t-distribution table or using statistical software.

It's important to note that calculating the p-value requires knowledge of the null hypothesis, alternative hypothesis, and the specific test being conducted. Statistical software, such as R or Python, can provide more accurate and efficient calculations of p-values for various statistical tests.

The probability that only the Asian project is successful given that at least one of the two projects is successful is:P(A|B) = P(A and B)/P(B) = 0.45/0.95 = 0.4737

(a) If the Asian project is not successful, the probability that the European project is also not successful is 0.6. Given, P(A) = 0.9 and P(B) = 0.5. Since the events are independent, the probability of not A happening and B not happening is the product of their individual probabilities, which is: 0.1 × 0.5 = 0.05.Therefore, the probability that the European project is also not successful is 0.6.

(b) To calculate the probability that at least one of the two projects will be successful, we will use the formula: P(A or B) = P(A) + P(B) - P(A and B), where P(A and B) is the probability that both projects will be successful. Given, P(A) = 0.9 and P(B) = 0.5.  Hence, P(A and B) = 0.9 × 0.5 = 0.45.Thus, the probability that at least one of the two projects will be successful is: P(A or B) = P(A) + P(B) - P(A and B) = 0.9 + 0.5 - 0.45 = 0.95.

The graph shows that initially, at t = 0 s, the turtle is at x = 50.0 cm. As time progresses, the turtle moves to the right, and at t = 40 s, the turtle is at x = 30.0 cm.

To sketch the graph of x versus t for the given time interval, we need to plot the turtle's position at different times using the given equation. Let's break it down step by step:

Given:

x(t) = 50.0 cm + (2.00 cm/s)t - (0.0625 cm/s²)t²

First, let's find the position of the turtle at t = 0 s:

x(0) = 50.0 cm + (2.00 cm/s)(0) - (0.0625 cm/s²)(0)²

x(0) = 50.0 cm

So at t = 0 s, the turtle is at the position x = 50.0 cm.

Next, let's find the position of the turtle at t = 40 s:

x(40) = 50.0 cm + (2.00 cm/s)(40 s) - (0.0625 cm/s²)(40 s)²

x(40) = 50.0 cm + 80.0 cm - 100.0 cm

x(40) = 30.0 cm

So at t = 40 s, the turtle is at the position x = 30.0 cm.

Now, we can plot these points on the graph. The x-axis represents time (t) and the y-axis represents position (x). We'll use a scale of 1 cm = 1 unit on both axes for simplicity:

When two-point charges, q1 and q2, are located near a conducting plane of infinite extent, we can determine the image charges needed to make the plane a surface of constant potential using the method of images.

To make the conducting plane a surface of constant potential, we need to ensure that the electric potential at each point on the plane remains the same.

This means that the electric field lines normal to the conducting plane must be perpendicular to it.

To achieve this, we introduce image charges that are mirror reflections of the original charges with respect to the conducting plane. The image charges have the same magnitude but opposite sign to the original charges.

In the case of a body of arbitrary shape with charge density ρ situated near a conducting plane of infinite extent, the image charge distribution required would involve creating mirror reflections of the charges within the body with respect to the conducting plane.

The image charges would have the same magnitude but opposite sign to the original charges. The specific distribution of image charges would depend on the shape and charge distribution of the body, and would be determined by applying the method of images.

Overall, the method of images allows us to determine the required image charge distribution to create a surface of constant potential for both point charges and bodies of arbitrary shape near a conducting plane of infinite extent.

The premium of this put is $5.28. A European put with underlying asset S, strike X, expiration T, risk-free rate r, and with R, the risk-neutral probability of up movement, can be priced as per the Black-Scholes model as follows:

C (S, t) = SN (d1) - Ke(-rT)N (d2) where d1= [log(S/X) + (r + σ2/2)(T - t)]/ σ√(T - t) and d2= d1 - σ√(T - t),σ is the standard deviation of the underlying asset returns. Similarly, the price of an American put option can be found using a binomial model, where the value of the option is calculated at every step. So, for the given American put option with underlying asset described by CRR notation S=$21, u=1.4 and d=0.7 and expiration in three time steps, we will have a binomial tree with three time steps as shown below:

Binomial Tree Now, let's calculate the premium for the American put option. At the third time step, when the stock price is $10.08, the put option is in-the-money, and the holder of the put option can exercise it and sell the stock at the strike price of $21. So, the premium at this node will be the maximum of the difference between the strike price and the stock price and zero, which is $21 - $10.08 = $10.92.

At the second time step, we will calculate the option price by discounting the expected future payoff by the risk-free rate. The probability of an up movement is R = 1.04, so the probability of a down movement is 1 - R = 0.96. For the node where the stock price is $14.70, the expected future payoff is

[R*$10.92 + (1 - R)*$0]/(1 + r)

= $5.25.

Similarly, for the node where the stock price is $7.35, the expected future payoff is [R*$0 + (1 - R)*$13.65]/(1 + r) = $6.63.

At the first time step, the expected future payoff is [R*$5.25 + (1 - R)*$6.63]/(1 + r) = $5.28. This is the premium of the American put option. Therefore, the premium of this put is $5.28.

The expression obtained is identical to the original convolution integral, we have shown that the convolution formula remains unchanged if the input x and impulse response h are swapped. This symmetry between x and h allows us to write it as "x(t) * h(t)".

To show that the convolution formula is unchanged when the input x and impulse response h are swapped, we need to prove the commutativity of convolution.

Let's consider the convolution integral:

y(t) = ∫[−∞[tex]]^[∞][/tex] x(τ)h(t - τ) dτ

Now, we will interchange the roles of x and h, and rewrite the convolution integral as:

y(t) = ∫[−∞[tex]]^[∞][/tex] h(τ)x(t - τ) dτ

By comparing the two expressions, we can observe that the only difference is the swapping of x and h in the integrand.

To prove the symmetry and commutativity of convolution, we can perform a change of variable in the second integral:

Let τ' = t - τ

The limits of integration remain the same, as the integral is taken over the entire real line. Differentiating τ' with respect to τ gives dτ' = -dτ.

Substituting these into the second integral, we have:

y(t) = ∫[−∞[tex]]^[∞][/tex] h(τ')x(t - τ') (-dτ')

Notice that the limits of integration do not change, as they are independent of the variable of integration.

Now, let's reverse the order of integration by changing the sign of dτ':

y(t) = ∫[∞[tex]]^[−∞[/tex]] h(τ')x(t - τ') dτ'

We can rename the dummy variable of integration back to τ:

The probability that the nearest integer to the value X is odd, given that X > 2022, is approximately 0.000122.

If the random variable X follows an exponential distribution with a mean of 1, then the probability density function (PDF) of X is given by:

f(x) = λ * e^(-λx)

where λ is the rate parameter.

Given that the mean of X is 1, we have:

1/λ = 1

which implies λ = 1.

To find the probability P that the nearest integer to the value X is odd, we need to calculate the cumulative distribution function (CDF) of X for values greater than 2022 and evaluate it at odd integers.

The CDF of the exponential distribution is given by:

F(x) = 1 - e^(-λx)

Substituting λ = 1, we have:

F(x) = 1 - e^(-x)

To find P, we need to subtract the probability that the nearest integer to X is even from 1 - P.

Let's calculate P(X is even) and subtract it from 1 to find P(X is odd):

P(X is odd) = 1 - P(X is even)

P(X is even) = P(floor(X) is even) + P(ceil(X) is even)

P(floor(X) is even) = P(X < 2022.5)

P(ceil(X) is even) = P(X < 2023.5)

Substituting these values into the CDF formula:

P(X is odd) = 1 - [P(X < 2022.5) + P(X < 2023.5)]

P(X is odd) = 1 - [1 -[tex]e^(-2022.5)[/tex] + 1 - [tex]e^(-2023.5)[/tex]]

P(X is odd) = [tex]e^(-2022.5)[/tex] - [tex]e^(-2023.5)[/tex]

Using the given value of e, which is approximately 2.71828, we can calculate this probability.

P(X is odd) ≈ 0.000122

A is approximately 7.960, b is approximately 9.352, and B is approximately 101 degrees.

Given C = 9 and A = 70 degrees, we can use the law of sines to find the missing values. The law of sines states that the ratio of the length of a side to the sine of its opposite angle is constant for all sides of a triangle.

a) To find side a, we can use the law of sines:

sin(A) / a = sin(C) / C

Substituting the given values, we have:

sin(70 degrees) / a = sin(9 degrees) / 9

Rearranging the equation, we get:

a = (sin(70 degrees) * 9) / sin(9 degrees)

Evaluating this expression, we find that a is approximately 7.960.

b) To find side b, we can use the law of sines:

sin(B) / b = sin(C) / C

Since we don't know angle B yet, we can use the fact that the sum of angles in a triangle is 180 degrees:

B = 180 degrees - A - C

Substituting the given values, we have:

B = 180 degrees - 70 degrees - 9 degrees

Evaluating this expression, we find that B is approximately 101 degrees.

Now we can use the law of sines to find sde b:

sin(B) / b = sin(C) / C

Substituting the values, we have:

sin(101 degrees) / b = sin(9 degrees) / 9

Rearranging the equation, we get:

b = (sin(101 degrees) * 9) / sin(9 degrees)

Evaluating this expression, we find that b is approximately 9.352.

The height the ladder reaches on the building is approximately 21.6 ft

The height the ladder reaches on the building can be found using trigonometry. We know that the ladder forms a right triangle with the ground and the building. The ladder acts as the hypotenuse of the triangle, and the angle between the ground and the ladder is given as 63 degrees.

Using the trigonometric function sine (sin), we can determine the height of the ladder on the building. The sine of an angle is equal to the ratio of the length of the side opposite the angle to the length of the hypotenuse. In this case, the height represents the side opposite the angle, and the ladder's length represents the hypotenuse.

Using the sine function:

sin(63 degrees) = height / 24 ft

To find the height, we can rearrange the equation:

height = 24 ft * sin(63 degrees)

Calculating this value, we find that the height the ladder reaches on the building is approximately 21.6 ft (rounded to one decimal place). Therefore, the ladder reaches a height of 21.6 ft on the building.

Let's consider the possible scenarios for the first coin:

If the first coin drawn is gold, there are five remaining coins, four of which are silver.

If the first coin drawn is silver, there are five remaining coins, three of which are gold.

Since we want to ensure that no two coins of the same color are adjacent, the second coin must be of the opposite color of the first coin.

In the first scenario, if the first coin is gold, the second coin must be silver. The probability of drawing a silver coin as the second coin is 4/9 since there are four silver coins remaining out of a total of nine coins.

In the second scenario, if the first coin is silver, the second coin must be gold. The probability of drawing a gold coin as the second coin is 3/9 since there are three gold coins remaining out of a total of nine coins.

Therefore, the overall probability that the first coin is gold is (4/9 + 3/9) = 7/9.

f is a linear transformation that is both injective and surjective, it is an isomorphism between X and F^n. Therefore, we have X ≅ F^n as desired.

To prove that X is isomorphic to F^n, where X is a finite-dimensional linear space over the field F of dimension n, we need to show that there exists an isomorphism between X and F^n.

Let (x_1, x_2, ..., x_n) be a basis of X. Any element x in X can be uniquely expressed as a linear combination of the basis vectors:

x = ∑(i=1 to n) μ_i * x_i, where μ_i ∈ F for all i.

Now, we define a function f: X -> F^n as follows:

f(x) = (μ_1, μ_2, ..., μ_n)

We claim that f is an isomorphism.

First, we need to show that f is well-defined, meaning that the mapping is independent of the choice of representation for x. Suppose x can be represented as a different linear combination of the basis vectors:

x = ∑(i=1 to n) ν_i * x_i, where ν_i ∈ F for all i.

Since both representations are linear combinations of the same basis vectors, we have:

∑(i=1 to n) μ_i * x_i = ∑(i=1 to n) ν_i * x_i

By the uniqueness of the representation, it follows that μ_i = ν_i for all i. Therefore, the function f(x) = (μ_1, μ_2, ..., μ_n) is well-defined.

Next, we need to show that f is a linear transformation. Let x, y ∈ X and α ∈ F. We have:

f(x + αy) = (μ_1 + αν_1, μ_2 + αν_2, ..., μ_n + αν_n)

         = (μ_1, μ_2, ..., μ_n) + α(ν_1, ν_2, ..., ν_n)

         = f(x) + αf(y)

This shows that f preserves vector addition and scalar multiplication, making it a linear transformation.

To prove that f is an isomorphism, we need to show that it is both injective and surjective.

Injectivity: Suppose f(x) = f(y), where x, y ∈ X. This implies (μ_1, μ_2, ..., μ_n) = (ν_1, ν_2, ..., ν_n), which further implies μ_i = ν_i for all i. Thus, x and y have the same unique representation in terms of the basis vectors, leading to x = y. Hence, f is injective.

Surjectivity: Let (a_1, a_2, ..., a_n) be an arbitrary element of F^n. We can construct an element x ∈ X such that f(x) = (a_1, a_2, ..., a_n) by choosing x = ∑(i=1 to n) a_i * x_i. This guarantees that f is surjective.

Since f is a linear transformation that is both injective and surjective, it is an isomorphism between X and F^n. Therefore, we have X ≅ F^n as desired.

The given ODE is exact and the potential function is [tex]g(x, y) = x^2 + c,[/tex]where c is an arbitrary constant. The solution of the IVP is[tex]y = 1/(x + 1).[/tex]

The given Ordinary Differential Equation is exact because

∂y/∂g1 = 2y = 2(x + 1) = ∂x/∂g2

The potential function g(x, y) can be found using the hint:

g(x, y) = F(x) + c(y)

where F'(x) = 2x and c(y) is an arbitrary function of y. We can choose c(y) such that g(0, 1) = 1, so

g(x, 1) = x^2 + c

Setting x = 0 and y = 1 in the Ordinary Differential Equation, we get c = 1, so the potential function is g(x, y) = x^2 + 1.

The solution of the IVP is given by

g(x, h(x)) = g(0, 1) = 1

which simplifies to

h(x)^2 + 1 = 1

Solving for h(x), we get h(x) = -1. Therefore, the solution of the IVP is y = 1/(x + 1).

The largest possible domain for this solution is the set of all real numbers (x, y) such that [tex]x^2 + y^2[/tex] = 1, which represents the unit circle in the xy-plane.

To solve the IVP 2x + 2y × y' = 0 and y(0) = 1 using the method of exact equations,

we need to show that the given ODE is exact and find the potential function g.

(a) Showing that the ODE is exact:

The ODE 2x + 2y × y' = 0 can be written in the form

g1(x, y) + g2(x, y) × y' = 0, where g1(x, y) = 2x and g2(x, y) = 2y.

To determine if the ODE is exact, we need to check if ∂g1/∂y = ∂g2/∂x.

∂g1/∂y = 0

∂g2/∂x = 2

Since ∂g1/∂y = ∂g2/∂x, the ODE is exact.

Now, we can find the potential function g(x, y):

Integrating g1(x, y) with respect to x, we get:

g(x, y) = ∫ g1(x, y) dx = ∫ 2x dx = [tex]x^2[/tex] + C(y)

Here, C(y) is an arbitrary function of y.

Taking the partial derivative of g(x, y) with respect to y, we have:

∂g/∂y = ∂/∂y ([tex]x^2 + C(y)[/tex]) = C'(y)

Setting ∂g/∂y equal to g2(x, y), we have:

C'(y) = 2y

Integrating both sides with respect to y, we get:

C(y) =[tex]y^2 + K[/tex]

Here, K is an arbitrary constant.

Therefore, the potential function g(x, y) is given by:

g(x, y) = [tex]x^2 + y^2 + K[/tex]

(b) Finding the solution of the IVP:

To find the solution of the IVP,

we need to solve the equation g(x, y) = g(0, 1), where g(x, y) =  [tex]x^2 + y^2 + K[/tex]

Substituting the initial condition y(0) = 1, we have:

g(0, 1) =[tex]0^2 + 1^2 + K[/tex]= 1 + K

So, the solution satisfies the equation [tex]x^2 + y^2 + K[/tex] = 1 + K.

Therefore, the solution of the IVP is given by the implicit equation:

[tex]x^2 + y^2[/tex]= 1

The largest possible domain for this solution is the set of all real numbers (x, y) such that [tex]x^2 + y^2[/tex] = 1, which represents the unit circle in the xy-plane.

Therefore, angle SUT is a right angle. Hence, its measure is 90 degrees.

Given that angle RST is a right angle. We know that a right angle is equal to 90 degrees. Therefore, we can write angle RST as m ∠RST = 90 degrees.It is also given that angle RSU has a measure of 25 degrees. We can write this as m ∠RSU = 25 degrees. Now, let's consider angle STU.

We know that the sum of the angles in a triangle is equal to 180 degrees.

m ∠RST + m ∠RSU + m ∠STU = 180 degrees.

Substituting the values we have, we get:

90 degrees + 25 degrees + m ∠STU = 180 degrees

Therefore, we can write:

m ∠STU + m ∠SUT + m ∠RSU = 180 degrees

Substituting the values we have, we get:

65 degrees + m ∠SUT + 25 degrees = 180 degrees

The magnitude of the acceleration is approximately -0.267 m/s², and the car does not hit the deer.

To find the magnitude of acceleration, we need to consider the forces acting on the car. The gravitational force component parallel to the incline is given by [tex]\( F_g = m \cdot g \cdot \sin(10^\circ) \)[/tex], where [tex]\( m \)[/tex] is the mass of the car and [tex]\( g \)[/tex] is the acceleration due to gravity. The frictional force opposing the motion is given by [tex]\( F_f = m \cdot g \cdot \cos(10^\circ) \cdot \mu_k \)[/tex], where [tex]\( \mu_k \)[/tex] is the coefficient of kinetic friction.

The net force acting on the car is the difference between the gravitational force and the frictional force: [tex]\( F_{\text{net}} = F_g - F_f \)[/tex].

Using Newton's second law, [tex]\( F_{\text{net}} = m \cdot a \)[/tex], where [tex]\( a \)[/tex] is the acceleration. We can solve for [tex]\( a \)[/tex] by rearranging the equation: [tex]\( a = \frac{F_{\text{net}}}{m} \)[/tex].

Substituting the given values and calculating the magnitude of acceleration:

[tex]\[ a = \frac{m \cdot g \cdot \sin(10^\circ) - m \cdot g \cdot \cos(10^\circ) \cdot \mu_k}{m} \\[/tex]

[tex]\quad = g \cdot (\sin(10^\circ) - \cos(10^\circ) \cdot \mu_k) \][/tex]

Now, let's calculate the value of the acceleration. We are given that the speed of the car is 25 mph, which is equivalent to [tex]\( 25 \times \frac{1609}{3600} \)[/tex] m/s.

Using [tex]\( g = 9.8 \, \text{m/s}^2 \)[/tex] and [tex]\( \mu_k = 0.4 \)[/tex], we have:

[tex]\[ a = 9.8 \cdot (\sin(10^\circ) - \cos(10^\circ) \cdot 0.4) \approx -0.267 \, \text{m/s}^2 \][/tex]

The negative sign indicates that the acceleration is in the opposite direction of the car's motion.

To determine if the car hits the deer, we need to compare the stopping distance of the car to the distance to the deer. The stopping distance can be calculated using the equation: [tex]\( d = \frac{v^2}{2 \cdot a} \)[/tex], where [tex]\( v \)[/tex] is the initial velocity and [tex]\( a \)[/tex] is the acceleration.

Substituting the given values, we have:

[tex]\[ d = \frac{(25 \times \frac{1609}{3600})^2}{2 \cdot (-0.267)} \approx 596 \, \text{m} \][/tex]

Since the stopping distance (596 m) is greater than the distance to the deer (25 m), the car does not hit the deer.

Therefore, the magnitude of acceleration is approximately [tex]\( -0.267 \, \text{m/s}^2 \)[/tex] and the car does not hit the deer.

The start variable S generates the language L(G) = L(r) = {w | w starts with aa and either ends with a or contains the substring ab}.

To convert the regular expression r = aa*(ab+a)* into a right-linear grammar G, we can follow the steps below:

Introduce a new start variable S in the grammar.

For each symbol in the alphabet, introduce a non-terminal that generates that symbol. That is, we have A -> a and B -> b.

Introduce a non-terminal for each Kleene star in the regular expression. That is, we have C -> aC or C -> ε.

Introduce a non-terminal for the concatenation of two sub-expressions. That is, we have D -> AB.

Introduce a non-terminal for the alternation of two sub-expressions. That is, we have E -> AB or E -> A.

Using these steps, we can construct the following right-linear grammar G:

S -> E

A -> a

B -> b

C -> aC | ε

D -> AB

E -> AD | C

The start variable S generates the language L(G) = L(r) = {w | w starts with aa and either ends with a or contains the substring ab}.

To see why, note that the non-terminal C generates any number of a's, including ε, and the non-terminal D generates a string of the form aa...ab or aa...aa. The non-terminal E then combines these two possibilities, generating any string that starts with aa and either ends with a or contains the substring ab.

When the determinant of matrix B is also 2.

When a scalar multiple of a row is multiplied by a matrix, the determinant of the resulting matrix is also multiplied by that scalar.

Given that the determinant of matrix A is det(A) = 2, and matrix B is obtained from A by multiplying the third row by 4, we can determine the determinant of B.

Let's denote the original matrix A as A₀ and the modified matrix B as B.

Multiplying the third row of A₀ by 4 yields matrix B. However, this operation does not affect the determinant of A₀, so det(B) = det(A₀).

Therefore, det(B) = det(A₀) = 2.

Hence, the determinant of matrix B is also 2.
