Find (2.2 x 10^7)(5 x 10^8)/(2.5 x 10^3)(8.8 x 10^5) expressed in scientific notation.

(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.

Find the solution set of this inequality. enter your answer in interval notation using grouping symbols. |8x-4| ≤ 12
