Question 94797: the equation d=1.2 square root h, gives the distance, D, in miles that a person can see to the horizon from a height ,h, in feet.
A. solve equation for h,
B. a national park peak is 14,255 feet in elevation. How far can you see to the horizon from the top of peak.
I am lost on how to solve the equation and then figure out the steps to take to come up with the answer for B.

the equation d=1.2 square root h, gives the distance, D, in miles that a person can see to the horizon from a height ,h, in feet.
:
A. solve equation for h,
1.2sqrt%28h%29 = d
Divide both sides by 1.2
sqrt%28h%29 = d%2F1.2
Square both sides:
h = %28d%2F1.2%29%5E2
:
B. a national park peak is 14,255 feet in elevation. How far can you see to the horizon from the top of peak.
Given the formula: d = 1.2* sqrt%28h%29
d = 1.2*sqrt%2814255%29; find Square Root on a calculator
d = 1.2 * 119.3943
d = 143.273 miles to the horizon from an elevation of 14,255 ft
