In desperate need. I have a D in this class. (Cal 1) Use implicit differentiation to find an equation of the tangent line to the curve at the given point. 16(x^2 + y^2) = (x^2 + y^2 - 5x)^2 (0, 4) (Limacon)

If the dimensions of a rectangular prism are 5 ft x 3.5 ft x 2 ſt, what is the surface area?

Asphere has a diameter of 10 in. what is the volume of the sphere?

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
