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
We are asked to solve for the area of the sector in a circle which central angle measures 125° and the circle also has a diameter of 13 feet. To solve this problem, we need to use the formula in solving area of a sector and it is shown below:
Area of a sector = (central angle / 360) * pi*r²
In the problem, we have radius = diameter / 2 which is r = 13/2 and r = 6.5 feet
Area = (125/360)*pi(6.5)²
Area = (125/360) * 3.14*6.5²
Area = 46.06 feet²
The answer is 46.1 feet².
