a.
To write: a compound inequality that determines the elevation range of trees in the low-elevation forest zone.
a.

Answer to Problem 12E
Explanation of Solution
Given:
The elevation of low-elevation forest zone is above 1700 feet to 2500 feet.
Let h denotes the elevation of trees in the low-elevation forest zone.
So, the compound inequality that determines the elevation range of trees in the low-elevation forest zone is:
b.
To write: a compound inequality that determines the elevation range of flowers in the subalpine and alpine zones.
b.

Answer to Problem 12E
Explanation of Solution
Given:
The elevation of subalpine zone is above 4000 feet to 6500 feet.
The elevation of alpine zone is above 6000 feet to summit.
It is also given that elevation of Mount Rainier is 14,410 feet.
Let h denotes the elevation of flowers in the subalpine and alpine zones.
So, the compound inequality that determines the elevation range of flowers in the subalpine and alpine zones is:

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?
