Problem
Name: ID: A 40. Graph the function \( d=\sqrt{1.5 h} \) which gives the approximate distance \( d \) in miles to the horizon, where \( h \) is the height of the viewer's eyes above the ground in feet. Approximately how high above the ground must a person be if the horizon is 7.6 miles away? 12 c
Solution
Step 1 ：Step 1: Plot the function \( d=\sqrt{1.5 h} \).
Step 2 ：Step 2: Substitute \( d = 7.6 \) into the equation: \( 7.6 = \sqrt{1.5 h} \).
Step 3 ：Step 3: Solve for \( h \) to determine the height above the ground: \( h = \frac{(7.6)^2}{1.5} \)
