Inverses and Radical Functions · Exercise 71

Determine the function described and then use it to answer the question.

The period $T,$ in seconds, of a simple pendulum as a function of its length $l,$ in feet, is given by $T (l) = 2 π \frac{l}{32.2}$ . Express $l$ as a function of $T$ and determine the length of a pendulum with period of 2 seconds.
