Answer:
May 4th, 2012.
Step-by-step explanation:
The highest level can be found with the help of the First Derivative and Second Derivative Tests. First and second derivatives of the function are, respectively:


The First Derivative Tests consists on equalizing the first derivative to zero and finding the critical points.

Roots are
and
. just the second root offer a realistic solution and is test by the second derivative.
(which leads to a maximum).
Given that a year has 365 days or 12 months, the highest water level occurs at day:

(May 4th).
