The number of months it will take for both cities to have the same population is; 36 months

We are given;

Current population of city of rock hill = 70000

Rate at which people move into  city of rock hill = 100 people per month

Rate at which people move out of city of rock hill = 150 people per month

Net average increase a month = 100 - 150 = -50 people per month

Current population of City of Greenville = 61000

Rate at which people move into  City of Greenville = 200 people per month

If the number of months it will take for both cities to have the same population is x, then it means that;

70000 - 50x = 61000 + 200x

Rearrange to get;

200x + 50x = 70000 - 61000

250x = 9000

x = 9000/250

x = 36 months

Note that in the above scenario, the original dimensions of the piece of metal that is rectangular are:

Let x equal the width of the box and x + 15 equal the length of the box.  

Subtract 6 (the amount cut out) from both of these to get the following terms: (x+9) and (x-6).  

These are the length and width of the box respectively.  We also know that the height of the box is 3.  Plugging these into the formula for the volume of a box gives you:

3(x+9)(x-6)=858

If the above is expanded, we have:

3x²+9x-162=858

Subtract 858 from both sides to make the quadratic equation equal zero.  Plug the a, b and c coefficients into the quadratic formula (or factor) to find x.

3x²+9x-162- 858 = 0

⇒ 3x²+9x -1020= 0

At the stage we solve for x:

3x2+9x−1020 = 0

Factor left side of the equation.

3(x−17)(x+20)=0

Set factors equal to 0.

x−17=0 or x+20=0

x=17 or x=−20

We can't get a negative side, so the answer that makes sense is x =17 recall that the metal is 15 inches longer than its width.

So if the Width is x and the Lenght is x +15

Then Width is 17 while the length is 17 + 15 = 32inces.

Thus the original dimensions of the metal are:

Length: 32 Inches

Width: 15 Inches

The value of B, the area of the base, is 1,540 m^2.

Value is the relative worth, merit, or importance of something. It can refer to an intangible concept such as a person's principles or a tangible object such as a rare coin. Values vary widely across cultures, societies, and individuals, and can even vary within the same individual over time. Value is often used to describe the worth of something in terms of its usefulness, beauty, or desirability. Value can also refer to the moral or ethical standards of a person or group.

The area of the base can be found by using the formula A = V/h where A is the area of the base, V is the volume, and h is the height. In this case, A = 26,214 / 17 = 1,540 m^2. Therefore, the value of B, the area of the base, is 1,540 m^2.

By evaluating the quadratic equation, we will see that the values of the expressions are:

f(-1) + f(4) = 27

f(-1) - f(4) =  -35

Here we need to work with the quadratic function:

f(x) = x^2 + 6x + 1

First, we want to find the value of the expression:

f(-1) + f(4)

To get that, we need to evaluate the quadratic equation:

f(-1) = (-1)^2 + 6*(-1) + 1

f(-1) = 1 - 6 + 1 = -4

f(4) = 4^2 + 6*4 + 1

f(4) = 16 + 24 + 1 = 31

Then the first expression is:

f(-1) + f(4) = -4 + 31 = 27

The second expression is:

f(-1) - f(4)

We already know these values, we can replace these to get:

f(-1) - f(4) = -4 - 31 = -35

The rectangular box dimensions are 21m ,12m and 10m.

What is volume of the rectangular box?

The area of the base times the height of the rectangular prism equals the volume of the object. As a result, the formula for a rectangular prism's volume is given. A rectangular prism's volume is equal to its length, width, and height in cubic units.

Here the dimensions of a box is 2x+5 , x+4 and x+2 meters and volume of the box is 2520 [tex]m^3[/tex].

Volume of rectangular box = w×h×l [tex]unit^3[/tex]

=> 2520 = (2x+5)(x+4)(x+2)

=> 2520 = [tex](2x^2+13x+20)(x+2)[/tex]

=> 2520 = [tex]2x^3+4x^2+26x+13x^2+20x+40[/tex]

=> [tex]2x^3-16x^2+33x^2-264x+310x-2480=0[/tex]

=> [tex]2x^2(x-8)+33x(x-8)+310(x-8)=0[/tex]

=> [tex](x-8)(2x^2+33x+310)=0[/tex]

Here x-8=0 and [tex]2x^2+33x+310=0[/tex]

Then x=8 and x ∈ R.

Now the dimensions 2x+5=2(8)+5=16+5=21m.

=> x+4 = 8+4=12 m.

=> x+2= 8+2 = 10m.

Hence the rectangular box dimensions are 21m ,12m and 10m.

The volume of the solid is 4π([tex]\frac{19}{6}[/tex]) and the integral of the f(x) , the line 2y=x, and x=2 is 3([tex]e^{4}[/tex] -1).

What is integral ?

An integral is a mathematical concept that is used to calculate the area under a curve or the total amount of change in a variable over a certain interval.

1)The first step is to find the intersection of the lines 2y=x and x=2. They will intersect at (2,1).

The second step is to find the intersection of the lines 2y=x and x=0. They will intersect at (0,0).

The third step is to find the integral over the region.

∫∫ (6e^(x^2))dxdy = ∫[0,2] (6e^(x^2))dx ∫[0,x/2] dy = ∫[0,2] (6e^(x^2))dx (x/2) = [3e^(x^2)] at [0,2] = 3e^(4) - 3e^(0) = 3(e^4 -1).

2)To find the volume of this solid, we can use the method of cylindrical shells.

we can find the function of the surface (1/3)x+(1/2)y+(1/4)z=1

by using cylindrical coordinates:

x = rcosθ , y = rsinθ , z = z

and substitute them in the equation (1/3)x+(1/2)y+(1/4)z=1

(1/3)rcosθ+(1/2)rsinθ+(1/4)z=1

(1/3)r(cosθ+2sinθ)+(1/4)z=1

z = 4(1-(1/3)r(cosθ+2sinθ))

V = ∫∫∫ 4(1-(1/3)r(cosθ+2sinθ)) rdrdθdz = 4π ∫[0,3] (1-(1/3)r(cosθ+2sinθ)) r^2 dr = 4π ∫[0,3] (1-r+(2/3)r^2) dr = 4π(3 - (3/2) + (2/3)) = 4π(19/6).

Hence , The volume of the solid is 4π([tex]\frac{19}{6}[/tex]) and the integral of the f(x) , the line 2y=x, and x=2 is 3([tex]e^{4}[/tex] -1).

Yes, the graph of linear equation is always a straight line.

Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

Consider the equation y = mx + c to define a linear function with a straight line as its graph.

We are aware that the rate of change, m, for a linear function is constant. On the graph, shifting by 1 always causes you to go up by m as shown in attached image.

The graph thus resembles a staircase. It is a straight line because it always rises in equal-sized steps.

If f '(t) =20/1 + t2 f(1) = 0, f is f(x) = 20tan⁻¹(t) - 5π.

Integrals are the values of the function seen by the process of integration.

The procedure of getting f(x) from F (x) is called integration.

Given f '(t) = 20/ 1 + t2 and f(1) = 0

We know that by definition of the integral of tan⁻¹(x) = 1/1 + t2

f '(t) = 20 / 1 + t2 = 20(1/ 1 + t2)

Integrate on both sides, we get

f(t) = 20tan⁻¹(t) + c

f(1) = 0; f(1) = 20tan⁻¹(1) + c = 0

c = -20(π/4) = -5π.

Therefore, f(x) = 20tan⁻¹(t) -5π.

If f '(t) =20/1 + t2 f(1) = 0, f is f(x) = 20tan⁻¹(t) - 5π.

Finding C is easy because C is simply the y-intercept(The point that crosses the y axis) which we can see from the graph is 4.

That allowed me to isolate possible answers of B and D because they contain a C which is equal to 4.

To determine which equation it was, i substituted an X coordinate to see if i got the correct Y coordinate from the graph.

Lets try B first and substitute the coordinate -3:

3/4 ×(-3)+4=1.75

As we see thats incorrect because the coordinate on the graph is (-3;0).

B. The total number of students is > 160.

C. The percent as a part-to-whole ratio is 16/100.

E. There are 1600 students in the school.

In Mathematics, a percentage can be defined as any number that is expressed as a fraction of hundred (100). This ultimately implies that, a percentage indicates the hundredth parts of any given number.

For the total number of students, we have:

Total number of students = 10/100 × T = 160

0.1T = 160

T = 160/0.1

T = 1,600 students.

Note: Percentage as a part-to-whole ratio is 10/100.
