The period of a pendulum is the time the pendulum takes to swing back and forth. The function relates the length L= 0.81t in feet of a pendulum to the time t in seconds that it takes to swing back and forth. A convention center has a pendulum that is 90 feet long. Find the period.

111.11 seconds

Step-by-step explanation:

Given: The period of a pendulum is the time the pendulum takes to swing back and forth

The function relates the length in feet of a pendulum to the time t in seconds that it takes to swing back and forth.

If L= 90 feet then put this in the above function, we get

Hence,  the period = 111.11 seconds
