14. A rectangular dog pen is 6 feet longer than the width. The perimeter of the pen is 48 ft. Find the length and the width of the pen.

(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.

What is the value of r of the geometric series?

If you answer right ill give brainliest, : )
