Question 635204: An arrow is shot into the air and its path is modeled by the function h(x) = -4.9t2 + 34.3t - 49 where "h" is the height of the arrow (given in meters) at any given time t (given in seconds). Find the number of seconds necessary for the arrow to reach its maximum height.
Thanks, it means a lot! :)

Hi,

h(x) = -4.9t2 + 34.3t - 49   || Note: 

h(x)= -4.9(x-3.5)^2 + 60.025 - 49

    V(3.5,11.025)

 Takes 3.5 sec to reach maximum height 0f 11.025m
