A snowmobile manufacturer claims that its newest model is 25% lighter than last year’s model. If this year’s model weighs 900 pounds, how much did last year’s model weigh?

(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.

Consider the function f(x)=-5x+3 what is f(-2)
