Aconstruction company purchased some equipment costing $300,000. the value of the equipment depreciates
(decreases) at a rate of 14% per year.
b. what is the value of the equipment after 9 years?

$ 77,198.22

Step-by-step explanation:

The value depreciates 14% per year, it means that for the first year, the value will be 0.86 of the initial value, the second year, 0.86 of the first, so 0.86x0.86 of it, and then  successively. So, for t years:

V(9) = 300,000*(0.86)⁹

V(9) = $ 77,198.22

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
