A certain forest covers an area of 3100. Suppose that each year this area decreases by 4.75% . What will the area be after 7 years?

9514 1404 393

  2205

Step-by-step explanation:

The area is multiplied by 1-4.75% = 0.9525 each year. After 7 years, the multiplication factor is 0.9525^7. Then the area is predicted to be ...

  3100 × 0.9525^7 ≈ 2205

300

step-by-step explanation:

28-600w < 300

28-600w > 300

600-28w < 300

600-28w > 300

see explanation

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
