sales of a portable MP3 player grew approximately exponentially from $0.06 billion in 1998 to $0.90 billion in 2002. predict sales of MP3 players in 2009.
\n" ); document.write( "this is where im stuck b=(12)^1/4
\n" ); document.write( "my answer sheet says this part of the equation should =1.861
\n" ); document.write( "---------------------
\n" ); document.write( "yes, 12^(1/4) is 1.861
\n" ); document.write( "----
\n" ); document.write( "But:
\n" ); document.write( "y = ab^x
\n" ); document.write( "0.9 = 0.06b^x
\n" ); document.write( "b^x = 0.9/0.06 = 15
\n" ); document.write( "-----
\n" ); document.write( "So b^4 = 15
\n" ); document.write( "Not sure where you got 12.
\n" ); document.write( "---
\n" ); document.write( "The b = 15^(1/4) = 1.968
\n" ); document.write( "===============================
