Asixth- grade math teacher can grade 25 homework assignments in 20 minutes. is he working at a faster rate or slower rate than grading 36 homework assignments in 30 minutes?

( comparing rates)

(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 g(x) is an odd function, which function must be an even function?

What values of x satisfy the inequality x^2-9x< 0? how is your answer shown on the graph?
