The height of a missile (h), in feet, is given by the equation h=8000t-16t^2, where t us time in seconds. What is the time it takes to reach the maximum height?

  • algebra -

    0 = 8000t -16t^2
    -16t( t-500) = 0
    t = 0, t= 500
    0r
    Max = 500/2 = 250
    Max
    t = -b/2a

    t = -8000/2(-16)
    t = 250
