An Experiment, Students Measured the Speed S (In Meters Per $t$

question 84

Multiple Choice

an experiment, students measured the speed s (in meters per second) of a falling object $t$ seconds after it was released. The results are shown in the table below. Use the regression capabilities of a graphing utility to find a linear model for the data. Round all numerical values in your answer to one decimal place.
$\begin{array}{|c|c|c|c|c|c|}\hline t & 0 & 1 & 2 & 3 & 4 \\\hline s & 0 & 13.0 & 21.4 & 31.2 & 41.4 \\\hline\end{array}$

• A) \(s = 10.1 t + 1.2\)
• B) \(s = 3.0 t - 1.2\)
• C) \(s = 1.2 t + 10.1\)
• D) \(s = 10.1 t + 3.0\)
• E) \(s = 1.2 t - 3.0\)
