PLS HELP!! There are 8 lifesavers in a roll and 3 of them are red. What is the probability of opening the roll and the 1st lifesaver is red? Write as a percent. (Only one end of the roll can be opened)

(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.

For f(x)=2x+1 and g(x)= x^2 -7, find (f•g)(x)

Write as a product of two polynomials. 2(3–b)+5(b–3)^2
