Can anyone please help me answer this math question right away? I need the correct answer right away!

If f(x) = x^3+ x^2- 4 and
g(x) = x^2 - 1
Evaluate
f(g(-2)) =

Lorenzo ate 2/5 of his bag of almonds. his 4 friends ate equal shares of the remaining bag of almonds?

(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.

Collin did the work to see if 10 is a solution to the equation r/4=2.4
