Ibought 4 pairs of jeans. my total bill including tax was 80.29. if each pair of jeans cost 18.50 before tax was added, what tax rate did i pay on the jeans

(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.

(60 points) explain this in detail

What is the ordered pair of m’ after point m (5, 6) is rotated 90° counterclockwise?
