Group A1. Facebook World DominationUse Facebook's own data to predict when everyone in the world will be on Facebook.

Our months are calculated from the beginning count on by month. December 2004 is 11 and Febuary 2010 is month 71.

the expo regression equation is a*b^x

472,032.54*1.1^x

X would be the number month you are trying to find. 1.1 is the constant for the increase in month for the 472032.54 people it increases each month.

Using this equation there are 472,032.54*1.1^73 (71+2)

This month there is 496,178,514.7 users!

In six months from now there will be...

472032.54*1.1^79 = 879,010,505.7 users on Facebook.

There are 6,813,552,087 people in the world right now.

472,032.54*1.1^x= 6,813,552,087

6,813,552,087/472,032.54= 14434.5

14434.5=1.1^x

log(14434.5)= x log(1.1)

log(14434.5)/log(1.1)=x

x= 100.49 months or 8.4 years until facebook consumes the earth.
