111 thirty dollars is to be divided among three girls and two boys so that each of the girls receives twice as much as each of the boys. how much does each receive?

(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.

Simplify the expression. -2/5(10+15m-20n)
