Answer

Step 3: Solve for \( h \) to determine the height above the ground: \( h = \frac{(7.6)^2}{1.5} \)

Steps

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: \( h = \frac{(7.6)^2}{1.5} \)
