The value of a house is increasing at 4.2% yearly. at this rate how long will it take for the value to double?
\n" ); document.write( ":
\n" ); document.write( "Let original value of the house = 1
\n" ); document.write( "Let t = time for this to happen
\n" ); document.write( "1*(1.042)^t = 2
\n" ); document.write( "Using logs
\n" ); document.write( "log(1.042^t) = log(2)
\n" ); document.write( "the log equiv of exponents
\n" ); document.write( "t*log(1.042) = log(2)
\n" ); document.write( "t = \"log%282%29%2Flog%281.042%29\"
\n" ); document.write( "using your calc
\n" ); document.write( "t = 16.847 yrs
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check this on your calc, enter: 1.042^16.847 ~ 2,00
\n" ); document.write( "
\n" );
