A ball is thrown into the air with an initial velocity of 30 meters per second.
The quadratic function h(t) = −4.9t^2 + 30t + 10 represents the height of
the ball above the ground, in meters, with respect to time t, in seconds.
Determine h(3) and explain what it represents.

    Answer:

    55.9

    Step-by-step explanation:

    The ball takes 3 seconds to go up 55.9 meters.

    3^2=9

    -4.9 x 9 = -44.1

    30 x 3 = 90

    -44.1 + 90 = 45.9

    45.9 + 10 = 55.9
