When Zakir threw a beach ball to his friend, its horizontal velocity changed as it traveled through the air. The relationship between the elapsed time, , in seconds, since Zakir threw the ball, and its horizontal velocity, V(t)V(t)V(t)V, left parenthesis, t, right parenthesis, in cm/s\text{cm/s}cm/sstart text, c, m, slash, s, end text is modeled by the following function: V(t)=4⋅(58)t Complete the following sentence about the rate of change of the horizontal velocity of the ball. Every second, the horizontal velocity of the bal
