What is the average common ratio between the successive height values of ball 1? Ball 2? Experimental errors may cause common ratios to have some variances within the data for one ball. Use the average common ratio.

Question

What is the average common ratio between the successive height values of ball 1? Ball 2?  Experimental errors may cause common ratios to have some variances within the data for one ball. Use the average common ratio.

ball 1 = 2.9
ball 2 = 2.08

What is the average common ratio between the successive height values of ball 1? Ball 2
is this asking for the common ratio between ball 1 and 2, or the attempts of ball 1 , if so you should have more attempts listed..

anonymous · Answer

it asking for the common ratio @shamil98

shamil98 · Answer

between what?

shamil98 · Answer

the successive height values of ball 1? 
There should be more than one value listed then..

anonymous · Answer

ok for ball one there are   
2.9 ft
 1.5 ft
 1 ft
0.6 ft
 0.46
ball 2:
  2.08
 1.25 ft
0.5 ft
 0.25
 stop bouncing

shamil98 · Answer

The common ratio is the number you multiply to get the next number , now it says that you will have variances with the common ratio so you are supposed to find the average of the ratios and use that..

shamil98 · Answer

What i'm a bit unsure is that the ratios between the terms are quite different..

shamil98 · Answer

2.9/1.5 = 1.93
1/0.6 = 1.67
0.6/0.46 = 1.3

anonymous · Answer

yeah it says to use the average common ratio

shamil98 · Answer

yeah just find the average of those ratios that i put forth. add them up and divide by the number of terms (which is 3)

shamil98 · Answer

find the common ratios for ball B the same way and average them the same way then

anonymous · Answer

What is the height of each ball on the fifth bounce (i.e., Height 6)? Use the geometric sequence formula, an = a1rn – 1 and show your work.
@shamil98

shamil98 · Answer

you have your average common ratio, your first term, so just plug it into the formula.

anonymous · Answer

then whats rn? @shamil98

anonymous · Answer

@shamil98

shamil98 · Answer

rn = r*n
r = ratio
n = the number of the term you want to find out
