The range of all real numbers x such that 2x − 5 < 7 and 4x 10 > 6 is

(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.

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)

This is about circle theorems. someone asap : (
