Hey there! Hello! 

So, to find population density, all you need to do is divide the number of people (in this case, the population estimate) by the area of the land you've been given. I'll show the first one for you:

36,500,000 / 163,707 = 222.959311, which rounds to 223. 

Hope this helped you out! Feel free to ask me any additional questions if you have any, or if you need any help with the other ones. :-)

Answer:

Population density is defined as the number of people per square unit of an area.

1. California = \frac{36500000}{163707} ≈ 223 people per square mile.

2. Florida = \frac{18300000}{65758} = 278.3 people per square mile.

3. Iowa = \frac{2990000}{56276} = 53.13 people per square mile.

4. New Jersey = \frac{8690000}{8722} = 1007.9 people per square mile.

5. Wyoming = \frac{522000}{97818} = 5.3 people per square mile.

What quadratic function does the graph represent?
nekit [7.7K]

Answer:

f(x)=-\frac{1}{3}(x-2)^2+4,

Step-by-step explanation:

The function of the graph can be written in the vertex form as

f(x)=a(x-h)^2+k, where V(h,k)=V(2,4) is the vertex of the quadratic function.

We substitute the value to obtain;

f(x)=a(x-2)^2+4,

The point (5,1) lies on the graph so we use it to determine the value of a.

1=a(5-2)^2+4,

1-4=a(3)^2,

-3=9a,

a=-\frac{1}{3}

The required equation is

f(x)=-\frac{1}{3}(x-2)^2+4,

What is the radius of a circle with an area of 78.5 cubic inches? Use 3.14 for pi. Enter your answer in the box.
UkoKoshka [18]

\bf \textit{area of a circle}\\\\ A=\pi r^2~~ \begin{cases} r=radius\\[-0.5em] \hrulefill\\ A=78.5 \end{cases}\implies 78.5=\pi r^2\implies \cfrac{78.5}{\pi }=r^2 \\\\\\ \sqrt{\cfrac{78.5}{\pi }}=r\implies 4.9987\approx r

How many solutions does the system have? y=−2x+4
Anna11 [10]

Answer:

There is only one solution and the solution is (0,4).

Step-by-step explanation:

The given system has equations;

y=-2x+4

and

y=x^2-2x+4

We equate the two equations to determine their point of intersection;

x^2-2x+4=-2x+4

\Rightarrow x^2-2x+2x+4-4=0

\Rightarrow x^2=0

\Rightarrow x=0

We put x=0 into the first equation to get;

y=-2(0)+4=4

There is only one solution and the solution is (0,4).
