Jerald jumped from a bungee tower. If the equation that models his height, in feet, is h = –16t2 + 729, where t is the time in seconds, for which interval of time is he within 104 feet above the ground?

To determine the time it takes for Jerald to reach 104 feet above the ground, we use the equation given above which is expressed as:

h = –16t2 + 729

We calculate as follows:

104 = –16t2 + 729
t = 6.25 seconds

Hope this answers the question. Have a nice day.
