Answer:

The number of students enrolled at a college is 18,000 and grows 3% each year. Complete parts (a) through (e).

a) The initial amount a is 18,000.

b) The percent rate of change is 3%, so the growth factor b is 1 + 0.03 = 1.03.

c) To find the number of students enrolled after one year, you calculate 18,000 · 1.03.

d) Complete the equation y = 18000 · 1.03^2 to find the number of students enrolled after x years.

e) Use your equation to predict the number of students enrolled after 21 years.

Answer:

The volume of the solid is 420m³

Step-by-step explanation:

The area of any pyramid is "1/3 · B · h", where B is the area of the base, and h is the height.

Knowing this we just need to solve for a couple of things.

First, and the easiest is the height of the triangle which (thankfully) is given to us. The height is 15m, which plus one number into our equation.

1/3 · B · 15

Second, we need to find the area of the base of the pyramid. That's done easily by finding the area of a triangle ( $\frac{base * height}{2}$ → $\frac{24*7}{2}$ → $\frac{168}{2}$ → $84$ ) giving us 84 units. This puts another number into our equation.
