00): In the year 2006 it was discovered that global population was increasing at the annual rate of 1.8%. In what year will the global population double?
----------------------------
A(t) = A(0)(1+ 0.018)^t
2A(0) = A(0)(1.018)^t
2 = (1.018)^t
---------------------
t*log(1.018) = log(2)
t = log(2)/log(1.018)
t = 38.85 years
----------------------------------
2006 + 38.85 = 2044.85
Rounded up you get the year 2045
