A rock is dropped from the top of a 2000-foot building. After second, the rock is traveling feet per second. After seconds, the rock is traveling feet per second. Let y be the rate of descent and x be the number of seconds since the rock was dropped. Part A: Write a linear equation that relates time x to rate y. (Hint: Use the ordered pairs (1,32) and (2,64) ) Part B: Use this equation to determine the rate of travel of the rock 17 seconds after it was dropped.

The rate is 224 ft/s

Step-by-step explanation:

Solving (a):

Given

Required

Determine the linear equation

First, we need to determine the slope using

The equation is then calculated using:

Add 32 to both sides

Solving (b):

Given

Required

Determine y

We have that:

Substitute 7 for x

Hence, the rate is 224 ft/s
