a helicopter takes off from the roof of a building that is 200 ft above the ground. The altitude of the helicopter increases by 150 feet each second.
\n" ); document.write( "1. create an equation to express the altitude of a helicopter as a function of time.
\n" ); document.write( "h(t) = 150t + 200
\n" ); document.write( "----------------------------------------------
\n" ); document.write( "2. calculate the altitude of the helicopter 90 seconds after take off.
\n" ); document.write( "h(90) = 150*90 + 200 = 13700 ft.
\n" ); document.write( "--------------------------------------------
\n" ); document.write( "3. How long does it take for the helicopter to reach 20,000 feet?
\n" ); document.write( "20000 = 150t + 200
\n" ); document.write( "150t = 19800
\n" ); document.write( "t = 132 seconds
\n" ); document.write( "========================
