Answer:

841.6 ft

Step-by-step explanation:

Solve this using the quadratic formula.

y=-16x^2+212x+139 becomes -16x^2 + 212x + 139.  The x-value of the axis of symmetry is

       -212

x = ----------- = 6.625  (This time measurement is in seconds.)

       2(-16)

The maximum height reached by the rocket is the y value when x = 6.625 and is y(6.625) = 841.6 ft
