Final answer:
The function s(t) = 3.1 ln(t) - 22 billion dollars represents a financial model. It calculates the value of an investment based on the natural logarithm of time. The question related to this function is likely about finding the value of the investment after a specific number of years or determining the rate of increase or decrease in its value over time.
Step-by-step explanation:
The function s(t) = 3.1 ln(t) - 22 billion dollars represents a financial model.
In this equation, t represents time in years and s(t) represents the value of an investment in billions of dollars at that time.
The function calculates the value of the investment based on the natural logarithm of time.
For example, if we plug in t = 2 into the equation, we can find the value of the investment after 2 years:
s(2) = 3.1 ln(2) - 22 = 3.1(0.693) - 22 = -19.13 billion dollars.
The question related to this function could be to find the value of the investment after a specific number of years, or to determine the rate of increase or decrease in the investment's value over time.
