Answer: I=sqrt(P/R)
Step-by-step explanation:
R=p/I^2
Multiple l squared on both sides...
(I^2) R=p/l^2 (l^2)
R(I^2)=p
Separate I by dividing both sides by R...
I^2=p/R
Square root both sides...
I=sqrt(P/R)
Answer:
40 inches
Step-by-step explanation:
We know that the height of water in a pool decreased 5 inches per week.
This means that we can form the equation 
, since the amount of water remaining is proportionate to the amount of weeks that have passed.
We know 
, since we need to find the change for 8 weeks.
The change will be the absolute value of -40, which just makes it positive, so 40.
