9) Find the tangent line approximationTto the graph offat the given point. Then complete the table. (Round your answer to four decimal places.)

f(x) = 5/x^2, (5,1/5)

T(x) =

x	4.9	4.99	5	5.01	5.1
f(x)
T(x)

10) According to Kepler's Third Law, the periodT(in days) of a satellite moving in a circular orbitxmi above the surface of the earth is given by

T= 0.0588(1+x/3959)^(3/2)

Suppose that a communications satellite is moving in a circular orbit26,000mi above the earth's surface. Because of friction, the satellite drops down to a new orbit25,500mi above the earth's surface. Estimate the decrease in the period of the satellite to the nearest one-hundredth hour. hours
