The function \( h(t) = -16t^2 + 75t \) represents the height of a ball thrown into the air after \( t \) seconds. The expression \( h(5) \) specifically calculates the height of the ball at \( t = 5 \) seconds.
Thus, \( h(5) \) represents:
A. The height of the ball 5 seconds after it had been thrown.
The other options do not accurately describe what \( h(5) \) indicates in this context.
