\n" ); document.write( ":
\n" ); document.write( "I assume you want to solve for p when you know d
\n" ); document.write( ":
\n" ); document.write( "The original formula
\n" ); document.write( "\".75%2Asqrt%282.8p%29\" = d
\n" ); document.write( ":
\n" ); document.write( "divide both sides by .75
\n" ); document.write( "\"sqrt%282.8p%29\" = \"d%2F.75\"
\n" ); document.write( "\"sqrt%282.8p%29\" = 1.33d
\n" ); document.write( ":
\n" ); document.write( "Square both sides
\n" ); document.write( "2.8p = (1.33d)^2
\n" ); document.write( "2.8p = 1.778d^2
\n" ); document.write( ":
\n" ); document.write( "Divide both sides by 2.8
\n" ); document.write( "p = \"%281.778d%5E2%29%2F2.8\"
\n" ); document.write( ":
\n" ); document.write( "You can check this: substitute 84 for d and confirm that p = 4480
