A triangle has side lengths of 3m2 + In-2, -2m2 + 7m - 4n+ 5 and 8m2+n+ + 6m + 1. What is the perimeter of the triangle?
2:
a)
11m2 + m - 11n +6
b) 9m2 + m2 + 13m + 3n + 8
3:
c) None of these
d)
24m2 - 2n +42m - 28n-10
e) 11m2 - n° +13m + 3n+4

(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.

What is the size of the matrix resulting from

If f(x)=x^3 and g(x)=2x+7 when g(x)=-5
