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
.
Answer:
1.50x+10=34
Step-by-step explanation:
The vertex is (-1,1)
Explanation
The vertex formula to find the x coordinate of the formula is -b/2a
So we plug in the values into the formula which is
-4/2(2)
Simplify it
-4/4
=-1
-1 is now the x cord of the vertex.
So now we will plug in the x into the quadratic equation which is 2x^2+4x+3
2(-1)^2 + 4(-1) + 3 = 2 -4 +3
Simplify it
5 - 4= 1
Y=1
So the Coordinates of the vertex is (-1,1)
You subtract 5 from both sides and get
X<2-5
Then you just solve how it is and keep the inequality
Point slope formula: y-y1=m(x-x1). Answer: y-7=6(x-(-4))
