Statistics 9 Data is collected on the sale of a particular model car over time. The following table is the sale price y verses the age x of the car. years X | 3 | 5 | 7 | 7 | 8 | 10 dollars Y | 16000 | 13000 | 11000 | 9500 | 8000 | 5500 a Make a suitable graph of these points. (years verses dollars) b Does there appear to be a linear relationship between the age and the value of a car? If so is there a positive or negative relationship? c Assuming the following equation to be an actual relationship between age and price find the value after 15 years. y = -1500 x + 20500

Write the equation of a sine function with Amplitude = 3 and Period = ̀. Type the equation in the form y = Asin(̀x) or y = Acos(̀x). Select the correct choice below and fill in the answer box to complete your choice. A. There are two equations; the equation when ̀ < 0 is y = and the equation when ̀ > 0 is y = . (Simplify your answers. Type an exact answer, using ̀ as needed. Use integers or fractions for any numbers in the expression.) B. There is one equation. It is y = . (Simplify your answers. Type an exact answer, using ̀ as needed. Use integers or fractions for any numbers in the expression.) C. There are two equations; the equation when A < 0 is y = and the equation when A > 0 is y = . (Simplify your answers. Type an exact answer, using ̀ as needed. Use integers or fractions for any numbers in the expression.)

A company tracks the value of a particular photocopier over a period of years. The data in the table below show the value of the copier at time $t,$ in years, after the date of purchase. $$\begin{array}{|c|c|}\hline\text { Time, } t \text { (in years) } & \text { Salvage Value } \\\hline0 & 534,000 \\1 & 22,791 \\2 & 15,277 \\3 & 10,241 \\4 & 6,865 \\5 & 4,600 \\6 & 3,084 \\ \hline\hline\end{array}$$ a) Use REGRESSION to fit an exponential function $y=a \cdot b^{x}$ to the data. Then convert that formula to $V(t)=V_{0} e^{-k t},$ where $V_{0}$ is the value when the copier is purchased and $t$ is the time, in years, from the date of purchase. (See the Technology Connection on p. 341 .) b) Estimate the salvage value of the copier after 7 yr; 10 yr. c) After what amount of time will the salvage value be $\$ 1000 ?$ d) After how long will the copier be worth half of its original value? e) Find the rate of change of the salvage value, and interpret its meaning.
