A lily pad grows so that each day it doubles its size. On the 1414th day of its life, it completely covers a pond. On what day was the pond half covered
-----------------------------
A(t) = Ao*2^t
------
pond area = Ao*2^(1414)
(1/2) pond area = (Ao/2)*2^1414
----
(1/2) pond area = Ao*2^(1413)
Ans: 1413th day
