A prism with a triangular base has a volume of 432 cubic feet. The height of the prism is 8

Rashid [163]

Answer:

9 feet

Step-by-step explanation:

Given:

A prism with a triangular base has a volume of 432 cubic feet.

The height of the prism is 8.

The triangle base has a base of 12 feet.

Question asked:

The height of the triangular base of the prism = ?

solution:

Volume of triangular prism = $Area of triangle \times height$

$432 = Area of triangle \times8$

Dividing both side by 8

$54 = Area of triangle$

$54 =$ $\frac{1}{2} \times base \times height$

$54 = \frac{1}{2} \times12\times height\\54 = \frac{12}{2} \times height$

Multiplying both side by 2

$108 = 12 \times height$

Dividing both side by 12

$9 = height$

Thus, height of the triangular base of the prism is 9

The number of rows in an auditorium can be represented by the function f(x) = 80x. The number of seats in each row can be repres

rusak2 [61]

Answer:

$h(x) = 80x^2 + 560x$

Step-by-step explanation:

To find the function h(x), that represents the total number of seats, we just need to multiply the functions f(x) (number of rows) and g(x) (number of seats per row):

$h(x) = f(x) * g(x)$

$h(x) = 80x * (x+7)$

$h(x) = 80x*x + 80x*7$

$h(x) = 80x^2 + 560x$

So the function that represents the total number of seats is:

$h(x) = 80x^2 + 560x$
