This will solved using the concept of proportionality:
(height of the cliff)/(height of the pole)=(base of the cliff)/(length from base of pole to the rope)
thus, let the height of the cliff be x, plugging the values in the formula we obtain:
x/6=86/7
hence solving for x we get
x=(86×6)/7
x=73.71 ft
D) Function A is non-linear and Function B is linear.
The volume would be 201.06

84.375 is the profit ALREADY made, so now subtract that from 180 dollars to get
