Answer:
The current amount of the Potassium-40 sample is approximately 37.521 grams.
Explanation:
The amount of the sample of the radioactive isotope decays exponentially in time, the amount of mass of the sample as a function of time (
), in grams, is described below:
(1)
Where:
- Initial mass, in grams.
- Time, in years.
- Time constant, in years.
The time constant can be found from half life (
), in years, described in statement:
(2)
If we know that 
, 
and 
, then the current amount of the sample is:
The current amount of the Potassium-40 sample is approximately 37.521 grams.

Explanation:
Body waters like lakes normally produces or receives some organic wastes, from the same living things of the environment or by pollution. In this example the fertilizers that were dropped into the lake, they have a lot of nitrogen, carbon or phosphorous compounds, that by the passing of the time will be consumed by the living things and elevate the production of zooplankton. with the increase of zooplankton, the population of fish is expected to increase also.
