Answer:
2500 people PER square mile
Step-by-step explanation:
THe population density is the population per unit area.
Here,
Given:
Population = 400,000
Total Area = 160 sq. miles
To get population density, we would need the population PER UNIT AREA, per miles.
We can get that by dividing the total population by total area:
400,000/160 = <u>2500 people PER square mile</u>
This is the population density.
>, because .5 is greater that .0
True. Every irrational number is included in the set of real numbers.
The irrational numbers are a subset of the real numbers.
The given
equation in this case is:
<span> y = -16 t^2 + 400</span>
We can see
that the slope of the equation is negative (-16) which means that the position
of Kay is on the positive y-axis , while the bottom of the river is in the
origin. This is supported by taking t = 0, the initial y becomes y = 400.
Therefore the position of Kay now is at (0, 400).
So to find
for the time when the camera hits the water, then y must be zero (t, 0) so we
have to find for t in this case.
When y = 0
0 = -16 t^2
+ 400
16 t^2 = 400
t^2 = 25
t = 5 s
<span>Therefore it
takes 5 seconds for the camera to hit the water and for Kay to see a splash.</span>
