Answer:
0.3 feet
Step-by-step explanation:
2.75(0.8)^x
in which x is the number of bounces after the firts bouce
bouce 12 would mean x=11
2.75(0.8)^11 = 0.2
In the smaller triangle, let
be the length of the smallest leg. Then the smallest leg in the larger triangle is
.
Within the scope of the smaller triangle, we have
such that

Then within the larger the triangle, we would have

Now we can solve for
:


Log(2x*12)=3
10^3=2x*12
1000=24x
1000/24=x
x=41.667
From least to greatest: |6.99|,|-7.09|,|7.15|,|-7.18|,|-7.21|. This is becauase every value will be positive because of the absolute value
