Solve the problem.
-The distance in miles that can be seen on the surface of the ocean is given by $\mathrm { d } = 1.4 \sqrt { \mathrm { h } }$ where $h$ is the height in feet above the surface of the water. How many feet high above the water (to the nearest tenth) would a pirate have to climb to see 16 miles?
A) $501.8 \mathrm { ft }$
B) $5.6 \mathrm { ft }$
C) $65.3 \mathrm { ft }$
D) $130.6 \mathrm { ft }$

To find the height $h$, set $d = 16$ and solve $16 = 1.4 \sqrt{h}$. Squaring both sides gives $256 = 1.96h$. Solving for $h$ gives $h \approx 130.6$ feet.

Solve the Problem d=1.4h\mathrm { d } = 1.4 \sqrt { \mathrm { h } }d=1.4h​

Solve the Problem $\mathrm { d } = 1.4 \sqrt { \mathrm { h } }$
