A certain ball is dropped from 204 centimeters, and has a rebound factor of 72% (The height of the ball after each bounce is 72% of the height of the bounce before.). Which equation represents the relationship between the the number of bounces, n, and height, h, in centimeters? Group of answer choices

Answer:

The equation that represents the relationship between the number of bounces and the height is [tex]H = 204\cdot 0.72^{n}[/tex].

Step-by-step explanation:

According to this exercise, we notice that maximum height of the ball ([tex]H[/tex]), measured in centimeters, is reduced at geometric rate and as a function of the number of bounces ([tex]n[/tex]), with no unit, which is defined by geometric progression:

[tex]H = H_{o}\cdot r^{n}[/tex] (1)

Where:

[tex]H_{o}[/tex] - Initial height of the ball, measured in centimeters.

[tex]r[/tex] - Bounce factor, no unit.

If we know that [tex]H_{o} = 204\,cm[/tex] and [tex]r = 0.72[/tex], then the equation that represents the relationship between the number of bounces and the height is:

[tex]H = 204\cdot 0.72^{n}[/tex] (2)
