Concept: Inverse Variation \n" ); document.write( "If F varies inversely with L then F=k/L, where k is a constant (number)\r \n" ); document.write( "\n" ); document.write( "Know: Usually in this problems, you have to find the constant before you can continue to find other frequencies or lenghts \r \n" ); document.write( "\n" ); document.write( "Answer: \n" ); document.write( "F=k/L \n" ); document.write( "175= k/3 \n" ); document.write( "3(175=k/3) \n" ); document.write( "3(175) = 3(k/3) \n" ); document.write( "525 = k \n" ); document.write( "***** \n" ); document.write( "Then F = 525/5 \n" ); document.write( "F= 105 \n" ); document.write( " |
