Algebra.Com's Answer #405059 by DrBeeee(684)![]() ![]() ![]() You can put this solution on YOUR website! I think that compunding continuously at p percent per year (expressed as a decimal) has the factor \n" ); document.write( "(1) e^p, where e = 2.71828... an irrational number named after Euler, a famous Swiss mathematician, 1707-1783. \n" ); document.write( "The balance, B, of account starting with principal, P, earning p percent per year for n years is \n" ); document.write( "(2) B = P*(e^p)^n \n" ); document.write( "For this example we have \n" ); document.write( "(3) B = 7000*(e^.06)^2 \n" ); document.write( "Using a calculator with the e^x key we get \n" ); document.write( "(4) B = 7892.478 \n" ); document.write( "The answer to the nearest cent is $7892.48. \n" ); document.write( "If you did not compound continuously but only yearly you would have \n" ); document.write( "(5) By = 7000*(1.06)^2 or \n" ); document.write( "(6) By = 7865.20 \n" ); document.write( "Giving $27.28 less. \n" ); document.write( " \n" ); document.write( " |
