use the following equation, where x and y are the measured in meters, to model a cross section of the Barringer Meteor crater, near Winslow, Arizona
\n" ); document.write( "--------------------------
\n" ); document.write( "y=1/1800(x-600)(x+600)
\n" ); document.write( "1) assuming the lip of the crater is at y=0, how wide is the crater?
\n" ); document.write( "(1/1800)(x-600)(x+600) = 0
\n" ); document.write( "(x-600)(x+600 = 0
\n" ); document.write( "Positive solution:
\n" ); document.write( "x = 600 meters
\n" ); document.write( "======================\r
\n" ); document.write( "\n" ); document.write( "2) what is the depth of the crater?
\n" ); document.write( "Assuming the crater is deepest in the center, let x = 300 meters;solve for y.
\n" ); document.write( "y = (1/1800)(300-600)(300+600)\r
\n" ); document.write( "\n" ); document.write( "y = (1/(1800)*-300*900
\n" ); document.write( "y = -150 meters
\n" ); document.write( "============================
