Math Problem Statement

The function f, of, t, equals, 7000, left parenthesis, 1, point, 0, 2, 5, right parenthesis, to the power tf(t)=7000(1.025)t represents the change in a quantity over t weeks. What does the constant 1.025 reveal about the rate of change of the quantity?

Solution

The function f(t)=7000(1.025)tf(t) = 7000(1.025)^t describes the change in a quantity over time, with tt representing the number of weeks.

In this function, 70007000 is the initial value (the quantity at t=0t = 0), and 1.0251.025 is the constant that plays a key role in determining the rate of change.

Interpretation of 1.0251.025:

  • The constant 1.0251.025 is the growth factor.
  • The rate of change is represented by the percentage increase each week, which can be found by subtracting 1 from 1.0251.025:
    1.0251=0.025 or 2.5%1.025 - 1 = 0.025 \text{ or } 2.5\% So, the quantity increases by 2.5% per week.

Conclusion:

The constant 1.0251.025 reveals that the quantity is growing at a rate of 2.5% per week.

  1. How can I find the value of the quantity after a specific number of weeks?
  2. What would happen if the constant was less than 1 (e.g., 1.0151.015)?
  3. How do I determine the time tt when the quantity reaches a certain value?
  4. Can this type of growth be used for other applications like population growth or finance?
  5. What happens to the growth rate if the exponent tt is replaced with 2t2t?

Tip: To convert a growth factor to a percentage rate, subtract 1 from the factor and multiply by 100.
