You can put this solution on YOUR website!
In the year 2000, you can say $\"+t+=+0+\"$
\n" ); document.write( "and $\"+N%280%29+=+10+\"$ in millions
\n" ); document.write( " $\"+N%28t%29+=+N%2Ae%5E%28r%2At%29+\"$
\n" ); document.write( " $\"+N%280%29+=+N%2Ae%5E%28.012%2A0%29+\"$
\n" ); document.write( " $\"+10+=+N%2Ae%5E0+\"$
\n" ); document.write( " $\"+N+=+10+\"$ at $\"+t=0+\"$
\n" ); document.write( "--------------------------------
\n" ); document.write( " $\"+13+=+10%2Ae%5E%28+.012%2At+%29+\"$
\n" ); document.write( " $\"+e%5E%28+.012t+%29+=+1.3+\"$
\n" ); document.write( " $\"+.012t+=+ln%28+1.3+%29+\"$
\n" ); document.write( " $\"+.012t+=+.2624+\"$
\n" ); document.write( " $\"+t+=+21.86+\"$
\n" ); document.write( "About 22 yrs have passed when population
\n" ); document.write( "reaches 13 M
\n" ); document.write( " \n" ); document.write( "

\n" );
