On solving the provided question, we can say that = 9227446, depreciation  If round at hundredth, then, Number of tree = 9227400.

Identify the asset's cost. Get the asset's total depreciable value by deducting the projected salvage value from the asset's purchase price. Determine the asset's useful life. The annual depreciation amount is obtained by dividing the sum of steps (2) and (3) by the figure determined in steps (3).

Depreciation is the practice of deducting the cost of a company asset over a number of years as opposed to just one. There are four primary ways to depreciate assets: linear, twofold declining, sum of the years' digits, and manufacturing units.

As it is given, 1% of left tree is decaying every year.

Number of tree left after 8 years.

A = P{1-R/100}^ = 10M{1-1%/100}^  

= 10M *(0.99)^

= 9227446

If round at hundredth, then,

Number of tree = 9227400.

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.

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:

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.

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)

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).

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).

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.
