All you have to do is write your question and someone will answer. For example, instead of writing "I do not understand how I find answers on here" you would ask something like what is 9*5? Then 2 people will see your question and answer. There are no pre-recorded answers, everything happens live. Hope this helps!
Answer:
A
Step-by-step explanation:
refer to the pic above
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
Answer:
2

Answer:
Step-by-step explanation:
In the morning he works four hours and 15 minutes and in the afternoon he works four hours and 15 minutes for a total of eight hours and 30 minutes. 30 minutes is 1/2 of an hour so he works for a total of 8 1/2 hours. Multiply this by his hourly rate which is $15 and this gives you $127.50
15 x 8.5 = 127.5
