The distance d in miles that can be seen on the surface of the ocean is given by d=1.3√(h,) where h is the height in feet above the surface. How high (to the nearest foot) would a platform have to see a distance of 13.5 miles?

\n" ); document.write( " $\"1.3sqrt%28h%29\"$ = d
\n" ); document.write( ":
\n" ); document.write( " $\"1.3sqrt%28h%29\"$ = 13.5
\n" ); document.write( ":
\n" ); document.write( " $\"sqrt%28h%29\"$ = $\"13.5%2F1.3\"$
