2. (5 pts) The table below gives the average high temperature, in °F, for Clemson, SC. Month Mar Apr May June July Aug Sept Oct Nov Dec Temp 63 72 80 87 90 89 83 73 64 54 Source: usclimatedata.com a. Look at the scatter plot of the data. Let Mar = 3, Apr 4, etc. What characteristics make a quadratic model an appropriate fit for the data? b. Find a completely defined quadratic model for the given data, T(m). c. Find and interpret T(1) in the context of the problem. d. Did you do interpolation or extrapolation in part c? Is your answer to part c considered reliable? Explain.

Planetary Velocity The following table gives the mean velocity of planets in their orbits versus their mean distance from the sun. Note that 1AU astronomical unit is the mean distance from Earth to the sun, abut 93 million miles. Planet d=distance AU v=velocity km/sec Mercury 0.39 47.4 Venus 0.72 35.0 Earth 1.00 29.8 Mars 1.52 24.1 Jupiter 5.20 13.1 Saturn 9.58 9.7 Uranus 19.20 6.8 Neptune 30.05 5.4 Astronomers tell us that it is reasonable to model these data with a power function. a Use power regression to express velocity as a power function of distance from the sun. b Plot the data along with the regression equation. c An asteroid orbits at a mean distance of 3AU from the sun. According to the power model you found in part a, what is the mean orbital velocity of the asteroid?
