The ratio for population density is population:area

Using this, we find that choices 1, 4, and 5 are true,

we know that

The population density is the number of people living in each unit of area. Is equal to the population divided by the total area.

so

Let

x------> population (number of people)

y------>the area in Km^{2}

z-----> the population density

z=\frac{x}{y}

Find the population density of the cities

City A

z=\frac{2,195,914}{1,553}=1,413.98\frac{people}{Km^{2}}

City B

z=\frac{48,592}{26}=1,868.92\frac{people}{Km^{2}}

City C

z=\frac{1,257,676}{999}=1,258.93\frac{people}{Km^{2}}

City D

z=\frac{196,429}{258}=761.35\frac{people}{Km^{2}}

<u>Statements</u>

<u>case A)</u> The population density for City B can be found using the ratio 48,592 : 26

The statement is true -------> see the procedure

<u>case B)</u> The population density for City D can be found using the ratio 258 : 196,429

The statement is False

Because, the population density for City D can be found using the ratio 196,429 : 258 ----> see the procedure

<u>case C)</u> City A has the greatest population density of the four cities

The statement is False

Because, the greatest population density of the four cities is the city B (see the procedure)

<u>case D)</u> The population density of City B is greater than that of City C

The statement is True -----> see the procedure

the greatest population density of the four cities is the city B

<u>case E)</u> City D has the lowest population density of the four cities

The statement Is True -------> see the procedure

Determine the domain of the function (fog)(x) where f(x)=3x-1/x-4 and g(x)=x+1/x
Katarina [22]

Answer: (-∞,-1) ∪ (0,+∞)

Step-by-step explanation: The representation fog(x) is a representation of composite function, meaning one depends on the other.

In this case, fog(x) means:

fog(x) = f(g(x))

fog(x) = 3(x+\frac{1}{x} )-\frac{1}{x+\frac{1}{x} } -4

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

fog(x)=3x+\frac{3}{x} -\frac{x}{x^{2}+x} -4

fog(x)=\frac{3x^{2}(x^{2}+x)+3(x^{2}+x)-x-4x(x^{2}+x)}{x(x^{2}+x)}

fog(x)=\frac{3x^{4}+3x^{3}+3x^{2}+3x-x-4x^{3}+4x^{2}}{x(x^{2}+x)}

fog(x)=\frac{3x^{4}-x^{3}-x^{2}+2x}{x(x^{2}+x)}

This is the function fog(x).

The domain of a function is all the values the independent variable can assume.

For fog(x), denominator can be zero, so:

x(x^{2}+x) \neq 0

If x = 0, the function doesn't exist.

x^{2}+x \neq0

x(x+1) \neq0

x+1\neq0

x\neq-1

<u>Therefore, the domain of this function is: </u><u>-∞ < -1 or x > 0</u>

Let f(x)=x+a/x+b such that f(f(1)=0 &amp; f(2)=-3 then a&amp;b resctivily are.
Yuliya22 [10]

Answer:

The value of a = - 1  ,   And b = \frac{ - 7 }{3}    

Step-by-step explanation:

Given as :

Function f(x) = \frac{(x + a)}{(x + b)}

And f(f(1)) = 0     And f(2) = - 3

Now For , x = 2 , y = - 3

I.e  f(2) = \frac{(2 + a)}{(2 + b)}

or,  - 3 = \frac{(2 + a)}{(2 + b)}

I.e 2 + a = - 6 - 3b

Or, a + 3b = - 8               ....... 1

Again  f(f(1)) = 0

So,  \frac{(1 + a)}{(1 + b)} = 0

Or,  1 + a = 0

∴    a = - 1

So , put htis value of a i n eq 1 , we get value of  b

So , - 1 + 3b = - 8

Or,   3b = - 7

∴       b = \frac{ - 7 }{3}

Hence The value of a = - 1  ,   And b = \frac{ - 7 }{3}    Answer
