A monkey throws a nut down to the ground from a branch 15 meters up. The function h(t)=-5t^2-10t+15 models the height of the nut, in meters, and t is the time in seconds
A)which zero needs to be discarded ?why?
Discard the negative zero.
Because it makes no sense.
============================
B)when will the nut hit the ground?
When h(t) = 0
