Answer:
10
Step-by-step explanation:
Given that t<span>he
native bird population in a city is decreasing at a rate of 10% per
year due to industrialization of the area by humans. The population of
native birds was 14,000 before the decrease began.
Thus f(1) = 14,000 and
f(n) = (1 - 0.1)f(n - 1) = 0.9f(n - 1)
Thus,
f(2) = 0.9f(1) = 0.9(14,000) = 12,600
f(3) = 0.9f(2) = 0.9(12,600) = 11,340
Therefore, After 3 years, 11,340 birds will remaiin.

Answer:
2/5x+2/5
Step-by-step explanation:
Answer:
the third one
Step-by-step explanation:
bc like there are 2 boxes of 1 and 5 boxes of 1/6 so thats already 2 and 5/6 which applies to all of them. then there is 1 box of 1 and 2 boxes of 1/3 so thats 1 and 1/3 which applies to all of them also but when you make them have the same denominator you get 2 and 5/6 + 1 and 4/6 which deletes the second one. When you add you should get the same denominator so that deletes the first one so then you simplify that and the fraction should still be equal to the unsimplified fraction so you should get 4 and 1/2 if that makes sense
