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

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

can you put the picture up?
