Please help me to solve the questions below in detail. Many thanks, and have a great day!

4) 5) a) Show using tangent line approximation that V 5.1 V3 is larger than V101 - m. b) The radius of a spherical ball is measured as 1.3 inches with a possible error of 0.04 inch. Use differentials to approximate both the possible propagated error and the percent error in computing the surface area of the sphere. Let f(x) = x3 + 4x + 20. :3) Explain using Calculus Why f has an inverse function (invertible). b) Ifg(x) = f "(35), nd the equation of the line tangent to the graph of g at x = 4
