Answer:
Step-by-step explanation:
<u>Let the depreciation rate is x per year, then we have:</u>
- 28000*x² = 22000
- x² = 22000/28000
- x² = 0.7857
- x = √0.7857
- x = 0.8864
<u>Exponential function for this case is:</u>
- V(t) = 28000*0.8864^t, where V(t) - future value, t- number of years
<u>Value of the car after 3 years:</u>
- V(3) = 28000*0.8864^3
- V(3) = 19500
Check the picture below.
make sure your calculator is in Degree mode.
So 53.5 + 12.9 =66.4 then thats a. -66.4
