Question

1. a plane descends from 30,000 ft at a constant rate of 2,500 feet per minute. which function best models the altitude? a. increasing linear b. decreasing linear c. increasing exponential d. decreasing exponential

Explanation:

Step1: Analyze the rate of change

The plane descends at a constant rate of 2,500 feet per minute. A constant rate of change indicates a linear function.

Step2: Determine the direction of change

Since the plane is descending (altitude is decreasing) as time passes, the function should be a decreasing linear function. Exponential functions involve a multiplicative rate of change, not a constant additive rate like 2,500 feet per minute.

Answer:

B. Decreasing linear
