Answer:
The model for the pollutant levels in the soil t years from the first measurement is:
Step-by-step explanation:
We have a first measurement of 65 parts per million (ppm) of pollutant.
We also know that the pollutant levels were growing exponentially at a rate of 4.5% a year.
We can model this as:
The value of Y0 is the first measurement, that correspond to t=0.
The ratio for the pollutant levels for two consecutive years is 1+0.045=1.045. This can be expressed as the division between Y(t+1) and Y(t), and gives us this equation:
Then, we have the model for the pollutant levels in the soil t years from the first measurement:
