At a height of h meters, you can see V kilometers to the horizon. These numbers are related by the equation V=3.5sqrt(h). A person can see 392 km from the horizon of an airplane window. How high is the airplance? The airplane is how many meters high? Simplify answer. Type an integer of fraction.
-------------------------
V(h) = 3.5*sqrt(h)
392 = 3.5sqrt(h)
sqrt(h) = 392/3.5
sqrt(h) = 112
h = = 112^2
h = 12,544 ft.
