erald jumped from a bungee tower. If the equation that models his height, in feet, is h = –16t2 + 729, where t is the time in se
conds, for which interval of time is he less than 104 feet above the ground?
2 answers:
104 = -16t^2 + 729
16t^2 = 729 - 104 = 625
t^2 = 625/16 = 39.0625
t = sqrt(39.0625) = 6.25
Answer= t > 6.25
Hopee this helps!(:
<span>h = –16t² + 729
</span> –16t² + 729<104
-16t²<104-729
-16t²<-625
t²>625/16
t>25/4
t>6.25
after 6.25 sec
