Solve the differential equation.cos x  + y sin x = sin x cos x

A. y = sin x ln |sec x| + C sin x B. y = cos x ln |sec x| + C cos x C. y = cos x ln |sec x + tan x| + C cos x D. y = cot x + C cos x

A. 4.8 B. 1.6 C. 4.2 D. 2.8

Form a polynomial f(x) with real coefficients having the given degree and zeros.Degree: 3; zeros: -4 and 3 - 2i

A. f(x) = x3 - x2 + 11x + 52 B. f(x) = x3 - x2 - 11x + 52 C. f(x) = x3 - 2x2 - 11x + 52 D. f(x) = x3 - 2x2 + 5x - 52
