To find: Difference of the given expression

Answer to Problem 2.3.16EP
Explanation of Solution
Given information:
Calculation:
While subtracting the numbers, the sign in final value will be the sign of greater number in expression. If both the numbers are negative, final value will be their sum with negative sign.
We know product of numbers with same sign is always positive and product of numbers with opposite sign is always negative.
Difference of the given expression can be calculated as shown:

- 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?
