A parachutist is 800 feet above the ground when she opens her parachute. She then falls at a constant rate of 5 feet per second. How do I write this out as an equation?
\n" ); document.write( ":
\n" ); document.write( "You want x = time in seconds and y = feet above the ground
\n" ); document.write( ":
\n" ); document.write( "Since it falls 5 ft every second, we have -5x feet from 800 ft
\n" ); document.write( "y = -5x + 800
\n" ); document.write( ":
\n" ); document.write( "The graph:
\n" ); document.write( "\"+graph%28+300%2C+200%2C+-20%2C200%2C+-200%2C+900%2C+-5x%2B800%29+\"
\n" ); document.write( ":
\n" ); document.write( "You can see that when x = 160 seconds, the height (y) = 0; (160*5 = 800)\r
\n" ); document.write( "\n" ); document.write( "
