Answer:
Population density = 
Step-by-step explanation:
The attached figure shows the dimension of an island.
Population density is equal to total population per unit land area.
Firstly we will find the area of the triangle using Pythagoras theorem as follows :

H is Hypotenuse, B is base and P is perpendicular

Area of triangle is given by :


Hence, the population density is
.

The first thing we are going to do to find (g°f)(3), is find (g°f)(x). To do that, we are going to evaluate g(x) at f(x):
(g°f)(x)=

Now, we can evaluate (g°f) at 3:




We can conclude that the correct answer is
c. 49
Answer:
2:1
Step-by-step explanation:
The original ratio is 4:2. Divide both sides by 2. Then you get 2:1.
