question 85

Multiple Choice

Line of best fit = -0.68x + 82.91
Choose the one alternative that best completes the statement or answers the question.
-Super Sally, a truly amazing individual, picks up a rock and throws it as hard as she can. The table below displays the relationship between the rock's horizontal distance, d (in feet) from Sally and the initial speed with which she throws. $$\begin{array} { l | c c c c c } \text { Initial speed( in ft/sec) , v } & 10 & 15 & 20 & 25 & 30 \\\hline \text { Horizontal distance of the rock (in feet) , d } & 9.9 & 14.8 & 19.1 & 24.5 & 28.2\end{array}$$ Assume that the horizontal distance travelled varies linearly with the speed with which the rock is thrown. Using a
Graphing utility, find the line of best fit, and estimate, rounded to two decimal places, the horizontal distance of the rock
If the initial speed is 33 ft/sec.

• A) 31.34 feet
