3. Depreciation: You're a big baller, so you bought a brand new BMW 7 Series back in 2012 with the performance V-8 xDrive engine. It cost a whopping $137,000. Fast forward five years later to 2017, and you
want to sell it. What you didn't know at the time is that on average, BMW 7 Series curs depreciate (decrease) in
value 17 8% each year. How much is your car worth after just these five years? Would you buy a new BMW
again knowing how much it loses in value?

72 is the answer to this problem

the answer is 8.64

step-by-step explanation:

add 8+12 to get a simplified answer of 12r-20

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
