What is the measure of an angle vertical to a 50 degree angle

Find the volume of the solid bounded by the plane z=0 and the paraboloid z=1-x^2 –y^2

If 5x - 2 = -12, then x = a) -50 b) -4.4 c) -2.8 d) -2

Ven the functions, f(x) = 5x2 - 3x + 1 and g(x) = 2x2 + x - 2, perform the indicated operation. when applicable, state the domain restriction. (f - g)(x) 3x2 - 4x + 3 3x2 - 2x - 1 3x2 - 4x - 1 3x2 - 2x + 3
