Exercise 15

Several applied functions are given below. In each case, find the indicated quantity (including unit) and interpret the value in the context of the application.

The period of a pendulum (s) is given by $\fe{P}{x}=\frac{6}{x+1}$ where $x$ is the number of swings the pendulum has made. Find and interpret $\frac{\fe{P}{29}-\fe{P}{1}}{29-1}$.
