In the summer a large pool evaporates water at 15% per day. if the pool starts out with 25,700 gallons of water, which function models the pool’s loss of water?

Step-by-step explanation:

we know that

In this problem we have a exponential function of the form

where

y ----> represent the pool’s loss of water

x ----> the number of days

a is the initial value

a=25,700 gal

b ----> is the base

r=15%=15/100=0.15

b=(1-r)=1-0.15=0.85

The function is equal to

d

step-by-step explanation:

d

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
