Answer to Problem 30PPS
Explanation of Solution
Given:
Sequence:
Calculation / Explanation:
The common difference of the arithmetic progression is:
So, the weight decreases by
Conclusion:
So, the common difference represents the weight of each year book, i.e.
c.
To determine the number of year books.
c.

Answer to Problem 30PPS
Explanation of Solution
Given:
The weight of the empty box:
The weight of the full box:
Calculation:
The weight of the books = The weight of the full box − The weight of the empty box
The number of year books = The total weight of the all books ÷ The weight of a single book
Conclusion:
So, there are total
d.
To determine the domain and range of the function
d.

Answer to Problem 30PPS
Explanation of Solution
Given:
Sequence:
Calculation:
The domain of the function is the numbers of year books.
The range of the function is the weight of the box contain the books.
So, the domain and range are respectively:
Conclusion:
Therefore, the domain and range are respectively:

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?
