1. Rick runs four miles on a treadmill in a total of 52 minutes. If he ran at a constant rate, how many minutes did he clock to cover a
distance of 3 miles?
2. The learning and development team conducted 45 training

(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.

How many solutions does the nonlinear system of equations graphed bellow have?

Ineed i been stuck on this question since yesterday
