A building includes a rectangular room that measures 38 feet long and 26 feet wide. The scale for the says that 1 inch on the blueprint is equivalent to 10 feet in the actual building. What are the dimensions of this rectangular room on the blueprint?

(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.

Determine whether the set of whole numbers is closed under addition. explain why the set is or is not closed. give an example.
