Question

The distance D , in miles to the horizon from an obsever's point of view over water or flat earth is given below , where H is the height of the point of view in feet . if a person whose eyes are 5ft above ground level is standing at the top of hill 45 ft above 'flat"earth, approximately how far to the horizon will she be able to see ?

D= sqaure route 2H

The distance to the horizon from the obsever's point of view is approximatley --- mi

Well, you have the formula.
What's the trouble?

Answer 2

Answer 3

The equation d = (1.35h)1/2 represents the distance d (in miles) you can see out into the horizon, where h is the height (in feet) of your eyes above ground level. Determine how tall a person is if he or she can see 2.75 miles out into the horizon. Round your answer to the nearest hundredth.
