While training for a race, Andre's dad ran 12 miles in 75 minutes on a treadmill. If he runs at that rate: How long would it take him to run 8 miles? How far could he run in 30 minutes? (Constant Speed)

(a) compute the maclaurin polynomial m2(x) for f(x) = cos x. (b) use the polynomial of part (a) to estimate cos π 12. (c) use a calculator to compute the error made using the estimate from part (b) for the value of cos π 12. remember that the error is defined to be the absolute value of the difference between the true value and the estimate.

5x + 2 = 12 solve the following equation. then place the correct number in the box provided.

Which shows the correct lengths of side c in both scales? scale 1: 45 m; scale 2: 60 m scale 1: 60 m; scale 2: 45 m scale 1: 36 m; scale 2: 27 m scale 1: 27 m; scale 2: 36 m mark this and return save and exit
