Exercise V: Depreciation (3 X 5 = 15 points) If a car is used for T years where 0 S T S 25, then its value V (in thousands of dollars) is given by 2T + 24000 1'3 WT) = (aw+3) You can use a calculator when needed, and round all answers to one decimal place. 1. When does the value of the car reach half its initial value? 2. Find V' (T). Simplify as much as possible. Then, evaluate and interpret V'(10). 3. Assume that after 25 years, the value of the car (still represented by V(T)) decreases linearly until it vanishes 5 years later. Sketch a graph of the entire function V(T) after writing its piecewise expression
