Elevation E, in meters, above sea leve at which the boiling point of water is
\n" ); document.write( "t degrees Celsius is given by the formula:
\n" ); document.write( ":
\n" ); document.write( "E = 1000(100-t) + 580(100-t)^2
\n" ); document.write( ":
\n" ); document.write( "At what elevation is the boing point 99.2 degrees Celsius?
\n" ); document.write( ":
\n" ); document.write( "Substitute 99.2 for t in the formula
\n" ); document.write( ":
\n" ); document.write( "E = 1000(100 - 99.2) + 580(100 - 99.2)^2
\n" ); document.write( ":
\n" ); document.write( "E = 1000(.8) + 580(.8)^2
\n" ); document.write( ":
\n" ); document.write( "E = 800 + 580(.64)
\n" ); document.write( ":
\n" ); document.write( "E = 800 + 371.2
\n" ); document.write( ":
\n" ); document.write( "E = 1171.2 meters above sea level
\n" ); document.write( " \n" ); document.write( "
\n" );
