help 4 * f(6)−6*g(5)=

(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.

If 7x=9y, y/z = 7/5 , then x/z = (a) 2/7 (b) 7/9 (c) 9/5 (d) 9/7 (e) 5/9

Will give brainliest, 5/5 rank and use the function rule, y=2x +5, to find the values of y when x=1,2,3, and 4. write the answer as ordered pairs that would be used to graph the function.
