Answer:
17%of 23000
17/100×23000
1 yrs depreciation is 3910
then
after 4 years depreciation is 4×3910
=15640
the worth of after 4 yrs is 23000-15640
=Rs 7360
A) 0.15 times $2,570 = $412.50
B) $122.85 times 2( 12 ) = $2,948.40
C) $2,570
D) All together it's $2,948.40 + $2,570 = $5,518.40
For D I didn't add the down payment because it's not an additional charge.
I only did the first one because I don't know if you want me to finish the rest.
Hope I helped :)
Step-by-step explanation:
Given that,
The diameter of the merry-go-round, d = 14 feet
Time taken, t = 6 seconds
Radius, r = 7 feet
The linear speed of the merry-go-round is given by :

Also,

Where
is the angular speed
So,

Hence, his linear and angular speeds are 7.33 m/s and 1.04 rad/s.
