if y=(kx^2)/sqaure root (P) find the % change in y if x inxreases by 10% and p decreases by 15%
\n" ); document.write( ".
\n" ); document.write( "\"y+=+%28kx%5E2%29%2Fsqrt%28P%29\"
\n" ); document.write( "Now, if
\n" ); document.write( "x = x+.1x = x(1+.1) = 1.1x
\n" ); document.write( "P = P-.15P = P(1-.15) = .85P
\n" ); document.write( ".
\n" ); document.write( "Plug the values in:
\n" ); document.write( "\"y+=+%28k%281.1x%29%5E2%29%2Fsqrt%28.85P%29\"
\n" ); document.write( "Working the numerator:
\n" ); document.write( "\"y+=+%28k%281.21%29x%5E2%29%2Fsqrt%28.85P%29\"
\n" ); document.write( "\"y+=+%281.21%29%28kx%5E2%29%2Fsqrt%28.85P%29\"
\n" ); document.write( "Working the denominator:
\n" ); document.write( "\"y+=+%281.21%29%28kx%5E2%29%2F%28sqrt%28.85%29sqrt%28P%29%29\"
\n" ); document.write( "\"y+=+%281.21%2Fsqrt%28.85%29%29%28kx%5E2%29%2Fsqrt%28P%29\"
\n" ); document.write( "\"y+=+%281.312%29%28kx%5E2%29%2Fsqrt%28P%29\"
\n" ); document.write( ".
\n" ); document.write( "Percent change:
\n" ); document.write( "\"%28%281.312%29%28kx%5E2%29%2Fsqrt%28P%29%29+%2F+%28%28kx%5E2%29%2Fsqrt%28P%29%29+%2A+100\"
