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.

Given :
On a number line, suppose the coordinate of A is 0, and AR = 15.
To Find :
the possible coordinates of the midpoint of AR.
Solution :
Their can be two points R which is at a distance of 15 units from the A .
One is -15 and other is 15.
Now, mid-point of A(0) and R(-15) is M (-7/2).
Also, mid-point of A(0) and R(15) is M (7/2).
Therefore, possible coordinates of the midpoint of AR is 7/2 , -7/2.
Hence, this is the required solution.
So their age can be no more than 22. And Martin is 6 years younger, which means you subtract.
22 ≥ x + x - 6
