Write the equation of a line that is parallel to the line 3x+5y=−1 and passes through the point (2,-1). Write your equation in standard form.

(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.

Solve each quadratic equation by factoring and using the zero product property. x^2 - 8x + 30 = 3x
