Question

22. A jet-ski's average speed, \( y \), (in knots) for several engine speeds, \( x \), in hundreds of revolutions per minute (RPM's) are shown below. \begin{tabular}{|l|c|c|c|c|c|c|} \hline Engine speed, \( x \) & 8 & 11 & 14 & 17 & 19 & 22.5 \\ \hline Jet ski speed, \( y \) & 8.97 & 14.18 & 19.62 & 26.05 & 31.29 & 43.13 \\ \hline \end{tabular} A. Find a polynomial model for the data. B. Use your model to estimate the average speed for the jet ski when the engine speed is 2500 RPM's. C. What engine speed will produce a jet-ski speed of 20 knots?
