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.

Arc cd located on circle a has a central angle of 135 the radius is the circle is 24 centimeters what is the length of arc cd
kherson [118]

\textit{arc's length}\\\\ s = \cfrac{\theta \pi r}{180}~~ \begin{cases} r=radius\\ \theta =\stackrel{degrees}{angle}\\[-0.5em] \hrulefill\\ r=24\\ \theta =135 \end{cases}\implies s=\cfrac{(135)\pi (24)}{180}\implies s=18\pi ~cm

Martin is 6 years younger than his sister. The sum of their ages is no more than 22 years.
Kobotan [32]

So their age can be no more than 22. And Martin is 6 years younger, which means you subtract.

22 ≥ x + x - 6
