An arrow is shot into the air a function representing the relationship between the number of seconds is in the air t and the height of the arrow in them in meters h is given by t equals -4.90x squared + 29.40x + 2.5 how long does it take the arrow to hit the ground
===================
h(t) = -4.90t^2 + 29.40t + 2.5 ----- not x
---
At impact, h(t) = -4.90t^2 + 29.40t + 2.5 = 0
Solve for t
