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
Answer:
Area of a circle is πr²
where r is the radius
r = 7.29m
Area = π × 7.29²
= 166.957
= 166.96m² to 2 decimal places

Tada! Hope that helps. :)
ANSWER:

STEP-BY-STEP EXPLANATION:
We have the following equation:

The inverse is the following (we calculate it by replacing f(x) by x and x by f(x)):

The domain would be the range of the original equation, and it would be the range of values that f(x) could take, which was from -4 to positive infinity, that is, f(x) ≥ -4.
Therefore, the domain is x ≥ -4.
So the correct answer is D.
