Answer: 4 / 5
Reasoning:
1) The function sine is defined as:
sin(x) = opposite-leg / hypotenuse
2) From the figure:
x = A
opposite-leg = 20
hypotenuse = 25
3) Calculations:
sin(A) = 20 / 25 = 4 / 5
Answer: 4 / 5
Answer:
100 resident/km
Step-by-step explanation:
In order to find the population density, we have to calculate the area of the township first.
We know that:
L = length = 5 km
W = width = 4 km
So the area of the township is
A=L\cdot W = 5 \cdot 4 = 20 km^2A=L⋅W=5⋅4=20km
2
Now we can find the population density by using
d=\frac{N}{A}d=
A
N
where N is the number of residents, and A is the area.
Substituting N = 2000, we find:
d=\frac{2000}{20}=100 res./km^2d=
20
2000
=100res./km
2
so, 100 residents per kilometer squared
The answer is 5, C = 5 units.
