Please help review this explain why its wrong and tell me whats right pls

The table shows the cost of several bunches of bananas. what equation can be used to represent the cost c of a bunch that weights p pounds?

Me ! write an equation for the interior angles of this triangle that uses the triangle sum theorem

(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.
