Answer:

Step-by-step explanation:
Given


Required
f(10)
An exponential function is represented as:

impleies that:
--- (1)
implies that
--- (2)
Divide (2) by (1)



Take 4th root

Substitute
in 


Solve for (a)


f(10) is calculated as:



Volume = (1/3) * base area * height
= 1/3 * 24 * 18
= 144 ft^3

To solve for

You first need to find a common denominator.
To do so, you need to make both denominators 10 by multiplying the top and bottom of

by 5

=

Reduce by dividing both the top and bottom by 2
