I need help with part b in the attached question. Please make sure to Round the x1^2​-coefficient to one decimal place as needed. Round all other constants and coefficients to the nearest integer as​ needed. Thanks

A ball is dropped from a height of 11 feet and bounces. Suppose that each bounce is 7/8 of the height of the bounce before. Thus, after the ball hits the floor for the first time, it rises to a height of 11() = 9.625 feet, etc. (Assume g = 32ft/s and no air resistance.) A. Find an expression for the height, in feet, to which the ball rises after it hits the floor for the nth time: hn = B. Find an expression for the total vertical distance the ball has traveled, in feet, when it hits the floor for the first, second, third and fourth times: first time: D= second time:D = third time: D = fourth time: D = C. Find an expression, in closed form, for the total vertical distance the ball has traveled when it hits the floor for the nth time. Dn =

A severe storm has an average peak wave height of u=16.4 feet for waves hitting the shore. Suppose that a reading of 38 waves showed an average weight height of x=16.9 feet. Previous studies of severe storms indicate that o=3.5 feet. Does this information suggest that the storm is increasing above the severe rating? Use a=0.01 

Suppose that y varies inversely as the 4th power of x, and that y=8y=8 when x=4x=4. What is y when x=8x=8? Round your answer to two decimal places if necessary.
