Applying an Exponential Function to
Newton's Law of Cooling
60. Water in a water heater is originally
Aa ←
122°F. The water heater is shut off and
the water cools to the temperature of the
surrounding air, which is 60°F. The water
cools slowly because of the insulation
inside the heater, and the value of k is
measured as 0.00351.
a. Write a function that models the
temperature T (t) (in °F) of the water t
hours after the water heater is shut off.
b. What is the temperature of the water
12 hr after the heater is shut off? Round
to the nearest degree.
c. Dominic does not like to shower with
water less than 115°F. If Dominic waits
24 hr. will the water still be warm
enough for a shower?
