When fighting a fire, the velocity v of water being pumped into the air is modeled by the function v= √2hg, where h represents the maximum height of the water and g represents the acceleration due to gravity (32 ft/s2).
\n" ); document.write( ":
\n" ); document.write( "The Islip Fire Department must purchase a pump that will propel water 90 feet into the air.
\n" ); document.write( " Will a pump that is advertised to project water with a velocity of 77 feet per second meet the fire departments need? EXPLAIN mathematically and verbally.
\n" ); document.write( ":
\n" ); document.write( "Find the velocity required, replace h with 90 ft, g with 32 ft/s
\n" ); document.write( "\"v+=+sqrt%282%2A90%2A32%29\"
\n" ); document.write( "v = 75.86 ~ 76 ft/sec
\n" ); document.write( "therefore a pump with a 77 ft/sec will just do it
\n" ); document.write( ":
\n" ); document.write( "Find the actual height (h) that a pump with 77 ft/s is able accomplish
\n" ); document.write( "\"sqrt%282%2Ah%2A32%29\" = 77
\n" ); document.write( "\"sqrt%2864h%29\" = 77
\n" ); document.write( "square both sides
\n" ); document.write( "64h = 77^2
\n" ); document.write( "64h = 5929
\n" ); document.write( "h = \"5929%2F64\"
\n" ); document.write( "h = 92.6 ft\r
