A blimp can be seen flying at an altitude of 7100 Blimp feet above a motor speedway during a race. The slanted distance directly to the pagoda at the d start-finish line is d feet. Express the horizontal 7100 ft distance h as a function of d. h The horizontal distance h as a function of d is h(d)= (Do not simplify. Do not factor. Type an exact answer, using radicals as needed.)
