You can put this solution on YOUR website!
c = 20e^-0.1t \r
\n" ); document.write( "\n" ); document.write( "..
\n" ); document.write( "\"c=+20%2Ae%5E%28%28-0.1%2A1%29%29\"
\n" ); document.write( "\"c=20%2Ae%5E%28-0.1%29\"
\n" ); document.write( "c=18.096\"mu\"g
\n" ); document.write( "..
\n" ); document.write( "Plug the value of 2 seconds
\n" ); document.write( "\"c=+20%2Ae%5E%28%28-0.1%2A2%29%29\"
\n" ); document.write( "\"c=20%2Ae%5E%28-0.2%29\"
\n" ); document.write( "c=16.374\"mu\"g\r
\n" ); document.write( "\n" ); document.write( "18.096-16.374=1.722mug/second
