Algebra.Com's Answer #519584 by josgarithmetic(39620)![]() ![]() ![]() You can put this solution on YOUR website! Your model is ... not bad. Try this: \n" ); document.write( "\n" ); document.write( "Simplify and solve for k. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now, let t=12 hours, and find the bacteria count. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Notice that my solution simply used three significant figures while yours used two significant figures in the k value. That is why you found C=2601. \n" ); document.write( " \n" ); document.write( " |
