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 less than 104 feet above the ground?

104 = -16T2 + 729

16t^2 = 729 - 104 = 625

4t = +/-25

t = +/-6.25

Between 6.25 and 13.5 seconds after he jumps
