In triangle abc, angle a=40, angle c=70, and bc=8.5. to the nearest tenth, what is ab?

(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.

On a piece of paper, graph y< x+1. then determine which answer matches the graph you drew.

Labc is reflected across x = 1 and y = -3. what are the coordinates of the reflection image of a after both reflections?
