Question

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, t, in seconds, since Zakir threw the ball, and its horizontal velocity, V(t), in cm/s is modeled by the following function: V(t) = 4 x(5/8)^t Complete the following sentence about the rate of change of the horizontal velocity of the ball. Every second, the horizontal velocity of the ball grows/shrinks v by a factor of Report a problem Stuck? Watch a video or use a hint.​

Answer 1

Answer:

5/8

Step-by-step explanation:

For khan the full correct answer is Shrinks by 5/8.

Answer 2

Every second, the horizontal velocity of the ball shrinks v by a factor of 5/8.

What is a Function?

A function is a law that relates a dependent and an independent variable.

The horizontal velocity in relation with elapse time is given by

$\rm V(t) = 4 x(\dfrac{5}{8})^t$

The rate of change of the the horizontal velocity of the ball is given by $\rm (\dfrac{5}{8})^t$

Every second, the horizontal velocity of the ball shrinks v by a factor of

$\rm (\dfrac{5}{8})^1$

= (5/8)
