document.write( "Question 1005968: In kick boxing, it is found that the force F needed to break a board varies inversely with the length L of the board. If it takes 30 pounds of force to break a board 2 feet long, how many pounds of force will it take it break a board that is 5 feet long? \n" ); document.write( "
Algebra.Com's Answer #622114 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! An inverse relationship like this can be written as \n" ); document.write( "FL = k \n" ); document.write( "Here 30*2 = 60 = k \n" ); document.write( "Then \n" ); document.write( "F(5) = 60 \n" ); document.write( "F = 12 pounds of force \n" ); document.write( " |
