If you are h feet above the Earth's surface, the distance, d, that you can see is approximately d (in miles) = square root of 3h/2.\r
\n" ); document.write( "\n" ); document.write( "Suppose you are on the roof of a building 900 ft. tall. How far can you see?(Calculate to two decimal places.)\r
\n" ); document.write( "\n" ); document.write( "==================================\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let d = 900\r
\n" ); document.write( "\n" ); document.write( "Plug into the formula and simplify.\r
\n" ); document.write( "\n" ); document.write( "d = sqrt{3h/2}\r
\n" ); document.write( "\n" ); document.write( "We are looking for d or the distance you can see.\r
\n" ); document.write( "\n" ); document.write( "d = sqrt{3(900)/2}\r
\n" ); document.write( "\n" ); document.write( "d = sqrt{2700/2}\r
\n" ); document.write( "\n" ); document.write( "d = sqrt{1350}\r
\n" ); document.write( "\n" ); document.write( "d = 36.742346\r
\n" ); document.write( "\n" ); document.write( "We now round to two decimal places. This means to round to the hundredths place.\r
\n" ); document.write( "\n" ); document.write( "So, the distance d that you can see is about 36.74 miles.\r
\n" ); document.write( "\n" ); document.write( "Understand?\r
