Since 1990, the number of arrivals of migratory birds to a wetland has been monitored. Based on the data collected over the years until 2022, a model was created to predict the size of the colony of migratory birds that would come to the wetland each year. The model was found to be
P = 3250(0.98)^t
Where P is the size of the colony (number of birds), and t is the time (t = 0 for year 1990). What do we know from this model about the number of arrivals of migratory birds to the wetland?

Select all the correct answers.

Accepted Answer

The model estimates that there were 3250 birds arriving in 1990.

Accepted Answer

The size of the colony in 2021 is 98% that of 2020.

Accepted Answer

The size of the colony of migratory birds arriving has been declining exponentially over the years at a constant rate of 2% each year.

Answer

The size of the colony of the migratory birds arriving has decreased exponentially with a total rate of decay of 2% between 1990 to 2022 inclusive.
