Question

100 POINTS HELP!!! Each time a tennis ball is used, its pressure is 999/1,000 what it was after the previous use

-Exponential growth
-Exponential decay
-Linear
-None of the above

Answer 1

B

Explanation:

Looking at the problem, we see that our constant rate is 999/1000 because the pressure is only nine hundred ninety-nine hundredths of the previous pressure. Since this is a rate, it can't be a linear function, so eliminate C.

Now, look at the rate. 999/1000 < 1, which means that the function is decreasing as the x values approach infinity or grow larger. That is an indication that this is an exponential decay.

The answer is thus B.
