The volume of a rectangular prism is (x4 + 4x3 + 3x2 + 8x + 4), and the area of its base is (x3 + 3x2 + 8). If the volume of a r

ectangular prism is the product of its base area and height, what is the height of the prism?

Dividing the volume by the base area, you find the height to be ...
\frac{x^{4}+4x^{3}+3x^{2}+8x+4}{x^{3}+3x^{2}+8}=x+1-\frac{4}{x^{3}+3x^{2}+8}

The height of the prism is x+1-\frac{4}{x^{3}+3x^{2}+8}

Solution:

Volume of Rectangular Prism = x^4 + 4 x^3 + 3 x^2 + 8 x + 4

Area of Base of Prism = x^3 + 3 x^2 + 8

As Given:

→→Volume of Rectangular Prism = Base Area ×  Height

→Height of Prism = \frac{\text{Volume of Rectangular Prism}}{Base Area}

→Height of Prism = \frac{ x^4 + 4 x^3 + 3 x^2 + 8 x + 4}{x^3+3 x^2+8}

                  =\frac{(x+1)(x^3 + 3 x^2 +8) - 4}{ x^3+3 x^2+8 }\\\\=(x + 1)- \frac{4}{x^3+3x^2+8}

B) Which one of the following points lies on the line 2y = 5x - 3?
sergeinik [125]
Given the equation 2y = 5x - 3:

A way to find out which of the ordered pair options lie on the line is to substitute their coordinates into the equation.


A) (2, 5)
2y = 5x - 3
2(5) = 5(2) - 3
10 = 10 - 3
10 = 7 (False statement). this means that (2, 5) is not a solution to the given equation.

B) (6, 3)
2y = 5x - 3
2(3) = 5(6) - 3
6 = 30 - 3
6 = 27 (False statement). this means that (6, 3) is not a solution to the given equation.

C) (3, -6)
2y = 5x - 3
2(-6) = 5(3) - 3
-12 = 15 - 3
-12 = 12 (False statement). this means that (3, -6) is not a solution to the given equation.

D) (3, 6)
2y = 5x - 3
2(6) = 5(3) -3
12 = 15 - 3
12 = 12 (True statement). This means that (3, 6) IS a solution to the given equation.

E) (2, -5)
2y = 5x - 3
2(-5) = 5(2) - 3
-10 = 10 - 3
-10 = 7 (False statement). this means that (2, -5) is not a solution to the given equation.

Therefore, the correct answer is Option D: (3, 6).

number of white beans = 35

number of black beans = 70

number of orange beans = 25

number of green beans = 47

<h3>Step 1</h3>

if two beans selected are different

6 C 2

(6 colours of beans)

<h3>Step 2</h3>

if two beans selected are same

6 C 1 = 6

(6 colours of beans)

<h3>Step 3 </h3>

The height of a building is 1734 ft. How long would it take an object to fall to the ground from the​ top? Use the formula s equ
koban [17]

Answer:

t is approximately 10.41 seconds

Step-by-step explanation:

s = 16t^2

1734 = 16t^2

divide by 16

1734/16 = 16t^2/16

1734/16 = t^2

take the square root  of each side

sqrt(1734/16) = sqrt(t^2)

we only take the positive square root because time must be positive

sqrt(1734/16) = t

t is approximately 10.41 seconds
