Hi,
The amount of water in a wading pool by given by the function w(t)=30+highlight%285%29t,
where "t" is time in minutes and t= 0 corresponds to when a faucet is turned on...
using Gallons
a. What is the rate of change of the water in the pool? 5gal/min
b. Is this an increasing or decreasing function?
c. How much water is in the pool an hour after the faucet has been turned on?
+w%28t%29=30%2B5t+=+30+%2B+5%2A60+=+330
