Find the area of the rectangle 4.3cm 8.6cm

(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.

Which of the following is an equation of a line parallel to the equation y=4x+1?

Can someone answer this question for me
