Compare the costs of bike trips form the two companies shown. For both, the cost is a linear function of the the number of days.

(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.

Express in the simplest form: (x^2+9x+14/x^2-49) / (3x+6/x^2+x-56)

Daniel expanded the expression as shown below -2(-8x-4y+3/4)=-10x-8y-11/4 what errors did he make? check all that apply
