Answer:
G A pool fills at a rate of 90 gallons per hour
Step-by-step explanation:
i dont know
as the exterior angle is known
sum of that angle and f angle = 180
142 + f = 180
f = 180 - 142
f = 38
2 1/2 and -2 1/2 beacause negative absolute value is the same number without negative sign
Given function:

To find:
The input if the output is 32.
The output if the input is 4.
Solution:
Input is x and output is c.
Substitute c = 32 in f(x).

Divide by 4 on both sides, we get


Taking cube root on both sides.

The input is 2 if the output is 32.
Substitute x = 4 in f(x).



The output is 256 if the input is 4.
