What is the range of the function represented by the graph?

Answer:

Yes

Step-by-step explanation:

The given points are A(−3,−1), B(−3,2), C(6,9), and D(3,9).

Plot these points on a coordinate plane as shown in the below graph.

Distance formula:

[tex]D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Using this formula, we get

[tex]AB=\sqrt{(-3-(-3))^2+(2-(-1))^2}[/tex]

[tex]AB=\sqrt{(0)^2+(3)^2}[/tex]

[tex]AB=3[/tex]

[tex]CD=\sqrt{(3-6)^2+(9-9)^2}[/tex]

[tex]CD=\sqrt{(-3)^2+(0)^2}[/tex]

[tex]CD=3[/tex]

Since AB=CD, therefore the required answer is yes, AB and CD are congruent.

Answer:

Ms. Davis=83 years

Her mom=126.33 years

Her daughter=66.67 years

Step-by-step explanation:

Let her mother's age=x

Ms. Davis= 7 dozens - 1

=(7*12)-1

=84-1

= 83 years

Ms. Davis= 7.2 + 60% of x

83=7.2 + .6x

83 - 7.2= .6x

75.8= .6x

Divide both sides by .6

75.8 / .6 = x

126.33 years

Ms. Davis daughter = 3.5 + 1/2 of x

=3.5 + 1/2(126.33)

=3.5 + 126.33 / 2

=3.5 + 63.165

=66.665

Approximately 66. 67 years

Answer:

B

Step-by-step explanation:

p(x) = x² - 2√2x + 1

p(2√2) = (2√2)² - 2√2*2√2 + 1

           =2²*(√2)² - 2*2*√2*√2  + 1

           = 4 *2 - 4*2 + 1

           = 8 - 8 + 1

           = 1

Answer:

B

Step-by-step explanation:

Given

p(x) = x² - 2[tex]\sqrt{2}[/tex] x + 1, then

p(2[tex]\sqrt{2}[/tex] )= (2[tex]\sqrt{2}[/tex] )² - 2[tex]\sqrt{2}[/tex](2[tex]\sqrt{2}[/tex] ) + 1 = 8 - 8 + 1 = 1 → B

Answer:

Decrease in TFR of 40%.

Step-by-step explanation:

Given that:

TFR (Total Fertility Rate) in 1995 = 5

TFR (Total Fertility Rate) in 2005 = 3

To find:

Percentage change in TFR from 1995 to 2005 = ?

Solution:

First of all, let us have a look at the formula for calculating the percentage change in any quantity.

Let p be the old value and

q be the new value.

Then percentage change is given as:

[tex]Percentage\ change = \dfrac{New\ Value - Old\ Value}{Old\ Value} \times 100[/tex]

Here, Old value is 5

New value is 3.

[tex]Percentage\ change = \dfrac{3 - 5}{5} \times 100\\\Rightarrow Percentage\ change = \dfrac{- 2}{5} \times 100\\\Rightarrow Percentage\ change = - 40\%[/tex]

Negative sign means there is a decrease of 40%.

So, Decrease in TFR of 40% is the answer.

We know the decimal place is after all those zeroes. Move the decimal x places to the left, until it is located between the 2 and 8. Since it moved 7 spaces, that is how you know the power of the ten. A faster way of doing this is the power is always one less than the number of digits of the number.

Answer:

VM=15

Step-by-step explanation:

4x-1=3x+3 becuase M is the mid point, which makes both sides equal.

Subtract 3x to both sides to get x-1=3.

Add 1 to both sides to get x=4.

Subsitue 4 into the equation 4x-1 to find the lengh of VM.

4(4)-1=

16-1=

15

Using the midpoint concept, it is found that the length of the line segment is of 30 units.

The midpoint divides the line into two segments of equal length, hence [tex]VM = MW[/tex].

Their lengths, as functions of x, are given by:

[tex]VM = 4x - 1[/tex]

[tex]MW = 3x + 3[/tex]

They have the same lengths, hence:

[tex]4x - 1 = 3x + 3[/tex]

[tex]x = 4[/tex]

Hence:

[tex]VM = 4x - 1 = 4(4) - 1 = 16 - 1 = 15[/tex]

[tex]MW = VM = 15[/tex]

The total length is:

[tex]T = VM + MW = 15 + 15 = 30[/tex]

The length of the line segment is of 30 units.

Answer:

The value of M is 91.

Step-by-step explanation:

Suppose T represents the tens digit and U represents the units digit.

Then the numbers M and N are:

M = 10T + U

N = 10U + T

Compute the value of M - N as follows:

M - N = 10T + U - 10U - T = 9T - 9U = 9 (T - U)

Given:

M > N

⇒ T - U > 0

⇒ T > U

Also, M - N is a multiple of 9.

Since M - N is a two-digit number, the possible values of M - N are:

18, 27, 36, 45, 54, 63, and 72

The values 81, 90 and 99 would not be considered since:

9 × 9 = 81

9 × 10 = 90

9 × 11 = 99

T - U = 9 (T - U) = 9 , 10 or 11 respectively and the largest difference for T − U we can get is 9 - 0 = 9 - 0 = 9.

Even this would result in N = 9, which is not a 2-digit number.

It is provided that the integer (M - N) has 12  factors.

Of the possible values of M - N the integer with 12 factors is 72.

The factors of 72 are:

1×72

2×36

3×24

4×18

6×12

8×9

So, M - N = 72.

⇒ M - N = 9 (T - U)

        72 = 9 × 8

⇒ T - U = 8

And since T > U, the values of T and U are:

T = 9 and U = 1

We cannot use T - U = 8 - 0 = 8, because then N will be not a two-digit number.

So, M = 91 and N = 19 and their difference is 72.

Thus, the value of M is 91.

Answer:

radius is 4.5 km

Step-by-step explanation:

Given :

Total number of people living in the area = 1.15 million = 1150000

Population density = 18075 people per sq kilometer

To find:

Radius of region = ?

Solution:

Population density of a region is defined as the ratio of total population divided by the area of the region.

Area here is circular. Let the radius be = r

Area of circle is given as [tex]\pi r^2[/tex]

Formula:

[tex]Population\ Density = \dfrac{Total\ population}{\pi r^2}[/tex]

Putting the values:

[tex]18075 = \dfrac{1150000}{\pi r^2}\\\Rightarrow r^2 = \dfrac{1150000}{18075\pi }\\\Rightarrow r^2 = \dfrac{63.62}{\pi }\\\Rightarrow r^2 = 20.26\\\Rightarrow \bold{r=4.5\ km}[/tex]

Therefore, radius is 4.5 km.

We have two fractions being divided. When we divide two fractions, we flip the second fraction and multiply

1/12 divided by 1/6 = 1/12 * 6/1

-------

From here we multiply straight across.

The numerators multiply to get 1*6 = 6

The denominators multiply to 12*1 = 12

Answer:

Option C.

Step-by-step explanation:

We know the following properties,

1. Product of an irrational number and a non-zero rational number is always an irrational number.

2. Sum of a rational and an irrational number is always an irrational number.

3. Sum or products of rational numbers are always a rational number.

In option A,

[tex]4\frac{2}{3}+\frac{\sqrt{3}}{9}[/tex]

Here, [tex]\sqrt{3}[/tex] is an irrational number.

[tex]\frac{\sqrt{3}}{9}[/tex] is an irrational number using property 1.

[tex]4\frac{2}{3}+\frac{\sqrt{3}}{9}[/tex] is an irrational number using property 2.

So, using the above properties we can say that this expression represents an irrational number.

Similarly,

In option B,

[tex]4\frac{2}{3}\times\frac{8}{\sqrt{3}}[/tex]

Here, [tex]\sqrt{3}[/tex] is an irrational number. So, using the above properties we can say that this expression represents an irrational number.

In option C,

[tex]4\frac{2}{3}-\frac{\sqrt{4}}{8}[/tex]

Here, [tex]\sqrt{4}=2[/tex], which is a rational number.

So, this expression represents a rational number using property 3.

In option D,

[tex]4\frac{2}{3}\times\frac{\sqrt{3}}{9}[/tex]

Here, [tex]\sqrt{3}[/tex] is an irrational number. So, using the above properties we can say that this expression represents an irrational number.

Answer:

The pedestrian fatality rate for California per 100,000 residents would be;

= (858/39,536,653) * 100,000

= 2.17 people per 100,000

In Arizona that figure is;

= (216/7,016,270) * 100,000

= 3.08 people per 100,000

This shows that even though California has a higher number of pedestrian fatalities in absolute terms, when this figure is made relative to population, Arizona has more pedestrian fatalities.

Answer:

C. 4

Step-by-step explanation:

To solve, set each parenthesis equal to the opposite side (0 in this case).

(x - 4)(x - 4) = 0

x - 4 = 0

Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Add 4 to both sides:

x - 4 (+4) = 0 (+4)

x = 0 + 4

x = 4

Do the same for the other parenthesis:

x - 4 = 0

x - 4 (+4) = 0 (+4)

x = 0 + 4

x = 4

C. 4 is your answer.
