the number of bacteria in a certain culture is given by the function b(t)=10000e^.04t
\n" ); document.write( "where t represents time in hours. how long will it take for the number of bacteria to reach 15000. round to nearest hundredth
\n" ); document.write( ":
\n" ); document.write( "\"10000%2Ae%5E%28.04t%29+=+15000\"
\n" ); document.write( "divide both sides by 10000
\n" ); document.write( "\"e%5E%28.04t%29+=+15000%2F10000\"
\n" ); document.write( "\"e%5E%28.04t%29+=+1.5\"
\n" ); document.write( "using natural logs
\n" ); document.write( "\"ln%28e%5E%28.04t%29%29+=+ln%281.5%29\"
\n" ); document.write( "log equiv of exponents
\n" ); document.write( ".04t*ln(e) = ln(1.5)
\n" ); document.write( "the nat log of e is 1. find the nat log of 1.5
\n" ); document.write( ".04t = .405465
\n" ); document.write( "t = \".405465%2F.04\"
\n" ); document.write( "t = 10.34 hrs to reach 15,000
\n" ); document.write( "
\n" ); document.write( "
\n" );
