Find the value of x..........

Answer:

The answer is below

Step-by-step explanation:

The question is not complete, but I would show how to solve.

Transformation is the movement of a point from its initial location to a new location. Types of transformation is reflection, translation, rotation and dilation.

Dilation is the enlargement or reduction of the size of an object by a factor.

If a point A(x, y) is dilated by a factor k with a center of dilation at (a, b), then the new point is:

A'(x, y) = [k(x - a) + a, k(y - b) + b]

Let us assume that point A(2, 0) dilation with a scale factor of 2 centered at (1, 2). Hence the new point is:

A'(x, y) = [2(2 - 1) + 1, 2(0 - 2) + 2]  = (3, -2)

Answer:

The total number of votes cast in the election was 11,141.

Step-by-step explanation:

To determine the number of negative votes in the voting, taking into account that the ratio of votes between positive and negative is 8 to 5 and that there were 6,856 positive votes, it is necessary to perform the following calculation:

6.856 / 8 x 5 = X

857 x 5 = X

4.285 = X

Therefore, there were 4,285 negative votes in the election. So, since 4,285 + 6,856 equals 11,141, the total number of votes cast in the election was 11,141.

Answer:

(0, 13)

Step-by-step explanation:

The midpoint is halfway between the line segment. First find the distance from the starting point to the midpoint.

2-1 = 1. So Since the midpoint is behind the start point, we are going backwards (moving to the left on the x axis).

So 1 space left from the midpoint is 1-1=0.

For y, the distance between the start and mid is 6 - -1 = 6+1 = 7 spaces. Then add 7 spaces to the midpoint value of 6, so 7+6 = 13. We moved upwards on the y axis.

Answer:

0.5

Step-by-step explanation:

Distance of OL = 0 - (-5)

                         = 0 + 5

                         = 5

Distance of OK = 2(5)

                          = 10

Gradient = [tex]\frac{rise}{run}[/tex]

               = [tex]\frac{0-(-5)}{10-0}[/tex]

               = [tex]\frac{5}{10}[/tex]

               = 0.5

Answer:

Thus, [tex]y=-\sqrt{x+3}[/tex] represents the transformed graph on the attached figure, which is a translated square root graph i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.

Step-by-step explanation:

Consider the function

y = f(x)

The rule of horizontal translation

y = f(x-h)

When 'h' is positive, the function is shifted to the right.

When 'h' is negative, the function is shifted to the left.

The rule of implying vertical reflection across the x-axis

y = -f(x)

Applying the rule:

We know that the square root function is

[tex]y=\sqrt{x}[/tex]

We know that if the graph would be reflected across the x-axis, then

[tex]y=-\sqrt{x}[/tex]

We know that   is horizontally translated or shifted 3 units to the left, it implies  +

3 inside the radical implies. Then the transformed function becomes .

Please check the attached diagram. From the diagram,

Thus, [tex]y=-\sqrt{x+3}[/tex] represents the transformed graph on the attached figure, which is a translated square root graph i.e. vertically reflected across the y-axis and also horizontally translated or shifted 3 units to the left.

Answer:

2y + 4z = x

Step-by-step explanation:

Given

[tex]x = -4[/tex]

[tex]y = -8[/tex]

[tex]z = 3[/tex]

Required

Write an equation that which is true for the above parameters

This question will be answered using trial by error method and the solution is not limited to one equation.

One equation that matches the values above is:.

[tex]2y + 4z = x[/tex]

To check:

Substitute the values of x, y and z in the above equation.

[tex]2y + 4z = x[/tex]

[tex]2 * -8 + 4 * 3 = -4[/tex]

[tex]-16 + 12 = -4[/tex]

[tex]-4 = -4[/tex]

Hence,

Because both sides of the equation are one and the same (-4), [tex]2y + 4z = x[/tex] is true for the above values of x, y and z.

A parachutist's speed during a free fall reaches 162 kilometers per hour. What is this speed in meters per second? At this speed, how many meters will the parachutist fall during 20 seconds of free fall? Do not round your answers.

Answer:

45 m/s ; 900 meters

Step-by-step explanation:

Given that :

Speed = 162 kilometers per hour ;

The speed in meters per second can be found by:

162 km/hr = (162 * 1000)m / (60 * 60) second

162 km/hr = 162000m / 3600 s

162 km/hr = 45 m/s

At this speed, how many meters will the parachutist fall during 20 seconds of free fall?

Speed of free fall = 45m /s

Distance in meters after 20 seconds :

(45 m/s * 20s) = 900 meters

Step-by-step explanation:

Plate: $8 each

Mug: $7 each

Spend Limit: $112

Items Wanted: 8

Considering she wants eight items, she can split that in half and buy four of each item, plate and mug.

8 * 4 = 32

$32 for 4 plates.

7 * 4 = 28

$28 for 4 mugs.

However, if she wanted to spend all the money, she could buy a few more of each item.

The answer is below

Step-by-step explanation:

Two triangles are said to be similar if their corresponding angles are equal and the corresponding sides are in proportion.

The distance between two points on the coordinate plane is given as:

[tex]Distance=\sqrt{(x_2-x_1}^2+(y_2-y_1)^2 \\\\Therefore\ in\ triangle\ PQR:\\\\|QR|=\sqrt{(-2-(-2))^2+(4-0)^2}=4\\\\|PQ|=\sqrt{(-2-4)^2+(0-4)^2}=\sqrt{52}=2\sqrt{13} \\\\|PR|=\sqrt{(-2-4)^2+(4-4)^2}=6[/tex]

In triangle STU:

[tex]|ST|=\sqrt{(-1-2)^2+(-2-(-4))^2}=\sqrt{13}\\\\|SU|=\sqrt{(-1-2)^2+(-4-(-4))^2} =3\\\\|TU|=\sqrt{(-1-(-1))^2+(-4-(-2))^2}=2[/tex]

|QR| / |TU| = 4/2 = 2

|PR| / |SU| = 6/3 = 2

|PQ| / |ST| = 2√13 / √13 = 2

Hence:

|QR| / |TU| = |PR| / |SU| = |PQ| / |ST|

Therefore, △PQR and △STU are similar triangles since the ratio of their sides are in the same proportion.

Similar triangles may or may not be congruent

Triangles PQR and STU are similar by SSS theorem.

The vertices of triangle PQR are given as:

[tex]P= (4, 4)[/tex]

[tex]Q= (-2, 0)[/tex]

[tex]R = (-2, 4)[/tex]

The vertices of triangle STU are given as:

[tex]S = (2, -4)[/tex]

[tex]T = (-1, -2)[/tex]

[tex]U =(-1, -4)[/tex]

Start by calculating the side lengths of the two triangles, using the following distance formula

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

For triangle PQR, we have:

[tex]PQ = \sqrt{(4 --2)^2 + (4 -0)^2} = \sqrt{52}[/tex]

[tex]PR = \sqrt{(4 --2)^2 + (4 -4)^2} = 6[/tex]

[tex]QR = \sqrt{(-2 --2)^2 + (0 -4)^2} = 4[/tex]

For triangle STU, we have:

[tex]ST= \sqrt{(2 --1)^2 + (-4 --2)^2} = \sqrt{13}[/tex]

[tex]SU= \sqrt{(2 --1)^2 + (-4 --4)^2} = 3[/tex]

[tex]TU= \sqrt{(-1 --1)^2 + (-2 --4)^2} = 2[/tex]

Check if the side lengths of both triangles are similar, by dividing corresponding sides

[tex]k = \frac{PQ}{ST} = \frac{\sqrt{52}}{\sqrt{13}} = 2[/tex]

[tex]k = \frac{PR}{SU} = \frac{6}{3} = 2[/tex]

[tex]k = \frac{QR}{TU} = \frac{4}{2} = 2[/tex]

Because the scale factors of the side lengths are the same, then both triangles are similar by SSS theorem.

Answer:

Speed = 25miles per hour

Step-by-step explanation:

Represent the time with x and the distance with y

So, from the attachment; we have the following details:

[tex](x_1,y_1) = (0.5,12.5)[/tex]

[tex](x_2,y_2) = (1,25)[/tex]

[tex](x_3,y_3) = (1.5,37.5)[/tex]

Required

Determine the constant speed

Because the train travelled at a constant speed, the speed can be calculated using:

[tex]Speed = \frac{y_3}{x_3}=\frac{y_2}{x_2}=\frac{y_1}{x_1}[/tex]

[tex]Speed = \frac{12.5}{0.5}=\frac{25}{1}=\frac{37.5}{1.5}[/tex]

[tex]Speed = 25=25=25[/tex]

Notice that the result of each division is the same.
