Math Problem Statement

Consider the following case of exponential growth. Complete parts a through c below. The population of a town with an initial population of 61,000 grows at a rate of 4.5% per year. b. Create a table showing the value of the quantity Q for the first 10 years of growth.

Solution

The problem involves exponential growth using the formula Q=61,000×(1+0.045)tQ = 61,000 \times (1 + 0.045)^t, where tt represents the year. The task is to create a table of population values over the first 10 years of growth.

The table provided in the image already lists population values rounded to the nearest whole number. To verify or calculate any missing entries, we use the formula to calculate QQ for each year tt (substitute tt values from 0 to 10).

Here is the step-by-step calculation:

  1. Formula: Q=61,000×(1.045)tQ = 61,000 \times (1.045)^t

Using the given formula, here’s how we calculate:

Example Calculation for t=1t = 1:

Q=61,000×(1.045)1=61,000×1.045=63,745(rounded to nearest whole number)Q = 61,000 \times (1.045)^1 = 61,000 \times 1.045 = 63,745 \, \text{(rounded to nearest whole number)}

Perform similar calculations for t=2,3,,10t = 2, 3, \ldots, 10 as needed.

Follow-Up Questions:

  1. How is the exponential growth formula derived, and why is it used in such cases?
  2. Can you compare the difference between exponential and linear growth for the same initial conditions?
  3. What does the growth rate of 4.5% imply for population trends over 20 or 30 years?
  4. How do rounding errors potentially affect the interpretation of population growth in practical scenarios?
  5. Can this model be adjusted for scenarios where the growth rate is not constant?

Tip: Always double-check calculations involving exponents to ensure rounding is accurate!
