12-14= -2
I hope this helps :) haha I was confused why you would need to know what 12-14 is
is the answer of the question
Answer: it will trave 56.89 meters before coming to rest.
Step-by-step explanation:
This is a geometric progression since the distance travelled (height) by the ball is reducing by a constant ratio, r. Since the number of times that the ball will bounce is infinite, then we would apply the formula for determining the sum of the terms in a geometric progression to infinity which is expressed as
S = a/(1 - r)
where
S = sum of the distance travelled by the ball
a = initial distance or height of the ball
r = common ratio
From the information given,
a = 128/9
r = (32/3)/(128/9) = 0.75
Therefore,
S = (128/9)/(1 - 0.75) = 56.89 meters
X + 12 + X - 6 = X + 50
2X + 6 = X + 50
X = 44
44 + 50 = 94
To check you can substitute X into the problem.
44 + 12 = 56
44 - 6 = 38
44 + 50 = 94
56 + 38 = 94
94 = 94
