Question

Complete the sentences.

Answer 1

Answer:

• years 1–4: 62.4 bass per year
• years 5–8: 67.6 bass per year

Step-by-step explanation:

If the population in year n is ...

  p(n) = 3000·1.02^n

then the average rate of change from year 1 to year 4 is ...

  (p(4) -p(1))/(4 -1) = 3000(1.02^4 -1.02^1)/3 = 1020·(1.02^3 -1) ≈ 62.4

The average rate of change for years 1–4 is 62.4 bass per year.

___

For years 5–8, the rate of change is similarly computed:

  (p(8) -p(5))/(8 -5) = 3000(1.02^8 -1.02^5)/3 = 1000·1.02^5·(1.02^3 -1) ≈ 67.6

The average rate of change for years 5–8 is 67.6 bass per year.
