Step-by-step explanation:
Let the height above which the ball is released be H
This problem can be tackled using geometric progression.
The nth term of a Geometric progression is given by the above, where n is the term index, a is the first term and the sum for such a progression up to the Nth term is
To find the total distance travel one has to sum over up to n=3. But there is little subtle point here. For the first bounce ( n=1 ), the ball has only travel H and not 2H. For subsequent bounces ( n=2,3,4,5...... ), the distance travel is 2×(3/4)n×H
a=2H..........r=3/4
However we have to subtract H because up to the first bounce, the ball only travel H instead of 2H
Therefore the total distance travel up to the Nth bounce is
For N=3 one obtains
D=3.625H

Answer:
- 120
Step-by-step explanation:
call x is the number you want to find
- (3/4 )x + 3
= (2/3)x - 6 - (3/4)x + (7/2) = (2/3)x - (13/2)
- (3/4)x - (2/3)x = - (13 /2) - (7/2)
- (1/12)x = -10
- x = -10 / (1/12) = -120
Answer:
13x + 12
