If model is of the form \"p=ae%5E%28-kt%29\"
\n" ); document.write( "then for the given half-life
\n" ); document.write( "\"1%2F2=1%2Ae%5E%28-k%2A5730%29\"
\n" ); document.write( "\"ln%281%2F2%29=-5730%2Ak\"\r
\n" ); document.write( "\n" ); document.write( "\"k=%28ln%281%2F2%29%29%2F%28-5730%29\"\r
\n" ); document.write( "\n" ); document.write( "\"k=0.000121\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "To use the formula and the other given information
\n" ); document.write( "\"p=3%2Ae%5E%28-0.000121%2A1000%29\"\r
\n" ); document.write( "\n" ); document.write( "\"p=3%2Ae%5E%28-0.121%29\"\r
\n" ); document.write( "\n" ); document.write( "\"p=%280.886%29%283%29\"\r
