Which system of linear inequalities is represented by the graph? y > One-thirdx + 3 and 3x – y > 2 y > One-halfx + 3 and 3x – y > 2 y > One-thirdx + 3 and 3x + y > 2 y > One-thirdx + 3 and 2x – y > 2

(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.

Can someone me with this problem i don't understand i need

Ijust need these 2 questions answered (the second pic is just confirmation i'm not confident in that answer)
