If Bryan randomly selects a T-shirt to wear, what is the probability it will be white?

What is the square root of 45? (step by step working plz)

(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.

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.
