Write an equation of a line passing through the point (4,-9) and parallel to the line 3x-6y=30

(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.

Determine which expressions represent real numbers and which expressions represent complex number. asaaap! plis!

What is the range? can’t seem to find it out
