What is x-y = 11 and 2xty=19

(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.

Aline passes through the point (–7, 5) and has a slope of 1/2 which is another point that the line passes through?

I’m confused on how to work the pie charts
