Step-by-step explanation:

Mathematicians seek and use patterns[8][9] to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof. When mathematical structures are good models of real phenomena, mathematical reasoning can be used to provide insight or predictions about nature. Through the use of abstraction and logic, mathematics developed from counting, calculation, measurement, and the systematic study of the shapes and motions of physical objects. Practical mathematics has been a human activity from as far back as written records exist. The research required to solve mathematical problems can take years or even centuries of sustained inquiry.

Rigorous arguments first appeared in Greek mathematics, most notably in Euclid's Elements.[10] Since the pioneering work of Giuseppe Peano (1858–1932), David Hilbert (1862–1943), and others on axiomatic systems in the late 19th century, it has become customary to view mathematical research as establishing truth by rigorous deduction from appropriately chosen axioms and definitions. Mathematics developed at a relatively slow pace until the Renaissance, when mathematical innovations interacting with new scientific discoveries led to a rapid increase in the rate of mathematical discovery that has continued to the present day.[11]

Mathematics is essential in many fields, including natural science, engineering, medicine, finance, and the social sciences.

Answer:

After finding like terms and solving, we get [tex]\mathbf{3x^2+3x+16}[/tex]

Step-by-step explanation:

We need to find like terms and simplify the expression [tex]4- 2x + x^2 + 5x + 12 + 2x^2[/tex]

Like terms: The terms who have same variable and exponent are called like terms.

So, Combining like terms and solving:

[tex]4- 2x + x^2 + 5x + 12 + 2x^2\\=4+12-2x+5x+x^2+2x^2\\Now \ solving:\\=16+3x+3x^2\\Rearranging \ the \ terms:\\=3x^2+3x+16[/tex]

So, after finding like terms and solving, we get [tex]\mathbf{3x^2+3x+16}[/tex]

Note: In the question given we have - and + sign with the term 5x i.e 4- 2x + x^2 -+ 5x + 12 + 2x^2

I have solved using +5x, but if the term is -5x then the solution will be:

[tex]4- 2x + x^2 - 5x + 12 + 2x^2\\=4+12-2x-5x+x^2+2x^2\\Now \ solving:\\=16-7x+3x^2\\Rearranging \ the \ terms:\\=3x^2-7x+16[/tex]

So, the answer will be: [tex]\mathbf{3x^2-7x+16}[/tex]

The solution for the system of equations → y = 3x + 1  and

4x - 3y = -13 is (2, 7)

The general equation of a straight line is -

[y] = [m]x + [c]

where -

[m] is slope of line which tells the unit rate of change of [y] with respect to [x].

[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.

The equation of a straight line can be also written as -

Ax + By + C = 0

By = - Ax - C

y = (- A/B)x - (C/A)

Given is the system of equations as -

y = 3x + 1

AND

4x - 3y = -13

Plot the graph of both of these equations. The point of intersection, would be the solution of this system of equations. Refer to the graph attached. These lines intersect at (2, 7)

Therefore, the solution for the system of equations → y = 3x + 1  and

4x - 3y = -13 is (2, 7)

Answer:

The ball will reach a maximum height of 39.993 meters after 1.428 seconds.

Step-by-step explanation:

Let suppose that no non-conservative forces acts on the ball during its motion, then we can determine the maximum height reached by the Principle of Energy Conservation, which states that:

[tex]K_{1}+U_{g,1} = K_{2}+U_{g,2}[/tex] (1)

Where:

[tex]K_{1}[/tex], [tex]K_{2}[/tex] - Initial and final translational kinetic energies, measured in joules.

[tex]U_{g,1}[/tex], [tex]U_{g,2}[/tex] - Initial and final gravitational potential energies, measured in joules.

By definition of translational kinetic energy and gravitational potential energy we expand and simplify the expression above:

[tex]\frac{1}{2}\cdot m\cdot v_{2}^{2}+m\cdot g\cdot y_{2}= \frac{1}{2}\cdot m\cdot v_{1}^{2}+m\cdot g\cdot y_{1}[/tex] (2)

Where:

[tex]m[/tex] - Mass of the ball, measured in kilograms.

[tex]g[/tex] - Gravitational acceleration, measured in meters per square second.

[tex]v_{1}[/tex], [tex]v_{2}[/tex] - Initial and final speed of the ball, measured in meters per second.

[tex]y_{1}[/tex], [tex]y_{2}[/tex] - Initial and final heights of the ball, measured in meters.

The final height of the ball is determined by the following formula:

[tex]v_{2}^{2}+2\cdot g\cdot y_{2} = v_{1}^{2}+2\cdot g\cdot y_{1}[/tex]

[tex]v_{1}^{2}-v_{2}^{2}+2\cdot g \cdot y_{1}=2\cdot g\cdot y_{2}[/tex]

[tex]y_{2} = y_{1}+\frac{v_{1}^{2}-v_{2}^{2}}{2\cdot g}[/tex] (3)

If we know that [tex]y_{1} = 30\,m[/tex], [tex]v_{1} = 14\,\frac{m}{s}[/tex], [tex]v_{2} = 0\,\frac{m}{s}[/tex] and [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], the maximum height that the ball will reach is:

[tex]y_{2} = 30\,m + \frac{\left(14\,\frac{m}{s} \right)^{2}-\left(0\,\frac{m}{s} \right)^{2}}{2\cdot \left(9.807\,\frac{m}{s^{2}} \right)}[/tex]

[tex]y_{2} = 39.993\,m[/tex]

The ball will reach a maximum height of 39.993 meters.

Given the absence of non-conservative forces, the ball exhibits a free fall. The time needed for the ball to reach its maximum height is computed from the following kinematic formula:

[tex]t = \frac{v_{2}-v_{1}}{-g}[/tex] (4)

If we know that [tex]v_{1} = 14\,\frac{m}{s}[/tex], [tex]v_{2} = 0\,\frac{m}{s}[/tex] and [tex]g = 9.807\,\frac{m}{s^{2}}[/tex], then:

[tex]t = \frac{0\,\frac{m}{s}-14\,\frac{m}{s} }{-9.807\,\frac{m}{s^{2}} }[/tex]

[tex]t = 1.428\,s[/tex]

The ball will take 1.428 seconds to reach its maximum height.

Step-by-step explanation:

Why it's right: they equal the same thing

5/45 = 1/9

Just plain wrong:

Answer:

✅[tex] p + 63.43 + 87.15 + 81.96 = 311.62 [/tex]

✅To take the lead, your score in the fourth round must be greater than 79.08.

Step-by-step explanation:

If you score, 63.43, 87.15, 81.96 in the first, second and third round respectively, if the current leader has a total score of 311.62 points, the point p that you need to score to equal 311.62 points, can be found using the following equation:

[tex] p + 63.43 + 87.15 + 81.96 = 311.62 [/tex]

Solve for the value of p

[tex] p + 232.54 = 311.62 [/tex]

Subtract 232.54 from each side

[tex] p = 311.62 - 232.54 [/tex]

[tex] p = 79.08 [/tex]

Answer:

A. [tex] c = 0.03p + 150 [/tex].

Step-by-step explanation:

The equation can be written in slope-intercept form as [tex] c = mp + b [/tex], where:

c = cash back (dollars)

p = value of purchases (dollars)

m = slope of the graph

b = y-intercept, which is the initial cash back award.

All we need to generate an equation that represents the graph, we need to find out the value of m and b.

b = until cash back award = 150

The slope, m, can be calculated using two points in the line, (1000, 180) and (2000, 210):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{210 - 180}{2000 - 1000} = \frac{30}{1000} = 0.03 [/tex]

Substitute m = 0.03, and b = 150, in [tex] c = mp + b [/tex].

The equation would be:

✅ [tex] c = 0.03p + 150 [/tex].

Answer:

2u = (2,4)

Step-by-step explanation:

Given that

Initial Point of vector = P1 = (2,-1)

Terminal point of vector = P2 = (3,1)

When the initial and terminal points of vector are given. The vector can either be directly found by using P2-P1 or the unit vectors i and j can be used.

So,

[tex]u =P_2-P_1 = (3-2 , 1-(-1))\\= (1, 1+1)\\=(1,2)[/tex]

Now we have to find 2u

So,

[tex]2u = 2(1,2) = (2,4)[/tex]

Hence,

2u = (2,4)

The two graphs are represented below.

Answer and Step-by-step explanation: One graph can "transform" into another through changes in the function.

There are 3 ways to change a function:

Now, the points for f(x) are:

(-5,0)  (0,6)  (5,-4)  (8,0)

And the points for g(x) are:

(-5,-3)  (0,-9)   (5,1)   (8,-3)

Comparing points:

(-5,0) → (-5,-3)

(0,6) → (0,-9)

(5,-4) → (5,1)

(8,0) → (8,-3)

It can be noted that x-coordinate is kept the same; only y-coordinate is changing so we have a vertical change. Observing the points:

(-5,0-3) → (-5,-3)

(0,6-15) → (0,-9)

(5,-4+5) → (5,1)

(8,0-3) → (8,-3)

Then, the vertical change is a Vertical Shift.

Another observation is that y-coordinate of f(x) is the opposite of g(x). for example: At the second point, y-coordinate of f(x) is 6, while of g(x) is -9. So, this transformation is also a Reflection.

Range of a function is all the values y can assume after substituting the x-values.

Domain of a function is all the values x can assume.

Reflection doesn't change range nor domain of a function. However, vertical or horizontal translations do.

Any vertical translation will change the range of a function and keep domain intact.

Then, for f(x) and g(x):

graph            translation            domain      range

f(x)                       none                 [-5,8]          [-4,6]

g(x)                vertical shift           [-5,8]          [-9,1]

In conclusion, this transformation (or translation) will affect the range of g(x)
