When Mustafa 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 Mustafa 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⋅(0.81)t Complete the following sentence about the percent change of the horizontal velocity of the ball. Every second, %\%%percent of horizontal velocity is the total horizontal velocity of the ball.

The rate at which the horizontal velocity of the ball changes every second is, 19%.

Step-by-step explanation:

The exponential decay function is given by:

Here,

y = final value

a = initial value

r = decay rate

t = time

The relationship between the elapsed time, t, in seconds, since Mustafa threw the ball, and its horizontal velocity, V (t) is:

The expression for the horizontal velocity of the ball represents the exponential decay function.

On comparing the two equations we get:

Thus, the rate at which the horizontal velocity of the ball changes every second is, 19%.

i think you should think about the question and not look online.
