Assume that the ball rebounds the same percentage on each bounce. using the initial drop height and the height after the first bounce, find the common ratio, r. note: round r to three decimal places. use this formula: (3 points: 2 points for showing your work, 1 point for the answer)

Let from the height at which ball was thrown = h units

It is given that , ball rebounds the same percentage on each bounce.

Let it rebounds by k % after each bounce.

Height that ball attains after thrown from height h(on 1 st bounce)=

Height that ball attains after thrown from height h (on 2 n d bounce)=

Similarly, the pattern will form geometric sequence.

S=

So, Common Ratio =

Common Ratio= 1 + the percentage by which ball rebounds after each bounce

the percentage by which ball rebounds after each bounce= negative integer= k is negative integer.

x= 149. 24+7=31. 180-31=149

your welcome

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.
