Answer:
Yes, you are correct.
Step-by-step explanation:
Ok, so this is a sum of aruthmetic sequence and also use some logic
it goes 10 feet down, then 5 up, 5 down, etc (see attachment)
so the total distance is the sum of all the numbers in the sequence doubled, minus the first term (since it didn't bounce 10 feet up, it started from top)
the sum of an aruthmetic is
Sn=

where a1=first term, r=common ratio and n=which time
first term=10
common ratio is 0.5
n=4
so
2[

]-10=answer27.5
the answer is 27.5 feet
Answer:
10
Step-by-step explanation: 17+10=27, 17-10=7
Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
iTones charges $10 per month, and $1 per song.
Music Mine charges $7 per month and $1.50 per song.
<u>To calculate the total cost for each option, we need to use the following formulas:</u>
iTones:
Total cost= 10 + 1x
x= number of songs
Music Mine:
Total cost= 7 + 1.5x
x= number of songs
First multiply 9x10 which is 90, then it would be 90^4 which is 65,610,000.
