What value of a makes sinA =cos20 degrees a true statement (need answer for both parts plz and ty)

Through non-collinear points there is exactly one plane.

Does the function satisfy the hypotheses of the mean value theorem on the given interval? f(x) = 4x^2 + 3x + 4, [−1, 1] no, f is continuous on [−1, 1] but not differentiable on (−1, 1). no, f is not continuous on [−1, 1]. yes, f is continuous on [−1, 1] and differentiable on (−1, 1) since polynomials are continuous and differentiable on . there is not enough information to verify if this function satisfies the mean value theorem. yes, it does not matter if f is continuous or differentiable; every function satisfies the mean value theorem.

Rewrite the following quadratic functions in intercept or factored form. show your work. y = 9 + 12x + 4x^2
