Take the equation <span> h (t) = 73 – 16 t^2 and plugin 9 for h(t) and then solve for t like the following:
</span>9 = 73 - 16 t^2
9 - 73 = 73-73 - 16t^2
-64 = -16t^2
-64 / -16 = -16t^2 / -16
4 = t^2
Now square both sides of 4 = t^2
2 = t
t = 2
Answer = 2 seconds
</span>9 = 73 - 16 t^2
9 - 73 = 73-73 - 16t^2
-64 = -16t^2
-64 / -16 = -16t^2 / -16
4 = t^2
Now square both sides of 4 = t^2
2 = t
t = 2
