The diagram shows Earth represented by circle O , a satellite at point B , and AB¯¯¯¯¯¯ tangent to circle O . AB is 21,800 mi. The radius of Earth is about 4,000 miles. What is the approximate distance from the satellite to the surface at point C ? Explain.
The image shows Earth represented by circle with centre O, a satellite is placed at point B and AB is tangent to the circle. O and B are joined which is having point C marked on circumference. Points O and A are joined.

A. 18,164 miles; AB¯¯¯¯¯¯ is a tangent and OA¯¯¯¯¯¯ and OC¯¯¯¯¯¯ are radii. Use the Pythagorean Theorem to find BO and subtract OC to find the distance the satellite is from the surface.
B. 22,164 miles; AB¯¯¯¯¯¯ is a tangent and OA¯¯¯¯¯¯ and OC¯¯¯¯¯¯ are radii. Use the point of tangency theorem to find the distance the satellite is from the surface.
C. 17,430 miles; AB¯¯¯¯¯¯ is a tangent and OA¯¯¯¯¯¯ and OC¯¯¯¯¯¯ are radii. Use the Pythagorean Theorem to find BO and subtract CB to find the distance the satellite is from the surface.

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.
