(a)

Answer to Problem 50PPS
The required log function is
Explanation of Solution
Given:
The number of humpback is 5000.
The population decrease at the rate of
Calculation:
Consider the relation between the population and the decrease rate is,
Write the above function as the log function as,
Thus, the required log function is

- 9:41 … 93 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?
