Which one doesn't belong 3500 km 3.5m 350 cm 3500 mm

(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 representation has a constant of variation of -2.5

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2
