document.write( "Question 1096163: the weight W that can be lifted by an automobile jack varies directly with the force F exerted downward on the jack handle. Suppose that a force of nine pounds will lift nine hundred and fifty-four pounds. use direct variation to write a complete model that expresses W as a Function of F \n" ); document.write( "

You can put this solution on YOUR website!
w = k * f\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "w is the weight
\n" ); document.write( "k is the constant of variation
\n" ); document.write( "f is the force.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "then the force is 9 pounds, the weight lifted is 954 pounds.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "formula becomes 954 = k * 9\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for k to get k = 954 / 9 = 106\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "formula becomes w = 106 * f\r
\n" ); document.write( "
