Answer:

2[tex]\sqrt{23}[/tex]

Step-by-step explanation:

The distance between the points (-4, -7) and (-8, -13) is 2√13 units as per the concept of distance between the two points.

To determine the distance between two points, we can use the distance formula, which is derived from the Pythagorean theorem. The formula is as follows:

[tex]Distance = \sqrt{((x2 - x1)^2 + (y2 - y1)^2)[/tex]

Given the two points (-4, -7) and (-8, -13), we can assign the coordinates as follows:

x1 = -4, y1 = -7 (coordinates of the first point)

x2 = -8, y2 = -13 (coordinates of the second point)

Now, we substitute these values into the distance formula:

[tex]Distance = \sqrt{(-8 - (-4))^2 + (-13 - (-7))^2)}\\\\= \sqrt{((-8 + 4)^2 + (-13 + 7)^2}\\= \sqrt{((-4)^2 + (-6)^2)}[/tex]

= √(16 + 36)

= √52

= 2√13

Therefore, the distance between the points (-4, -7) and (-8, -13) is 2√13 units.

The equations that represent proportional relationships are:

A. 2x/12 = 3x/18

C. 4/6 = 10/15

E. 5/5 = 11/11

To determine if an equation represents a proportional relationship, ensure each side of the equation gives the same value when simplified. If they do not have the same value, then the equation does not represent a proportional relationship.

A. 2x/12 = x/6

3x/18 = x/6

Therefore, 2x/12 = 3x/18 represents a proportional relationship.

B. 3/6 = 1/2

6/3 = 2

Therefore, 3/6 = 6/3 does not represent a proportional relationship.

C. 4/6 = 2/3

10/15 = 2/3

Therefore, 4/6 = 10/15 represents a proportional relationship.

D. 4x/18 = 2x/9

x/18 = x/18

Therefore, 4x/18 = x/18 does not represent a proportional relationship.

E. 5/5 = 1

11/11 = 1

Therefore, 5/5 = 11/11 represents a proportional relationship.

F. 8/15 = 8/15

4/30 = 2/15

Therefore, 8/15/2/15 does not represent a proportional relationship.

3 × 90 thus equals 280 degrees.

The figure moves onto the following quadrant of the graph with each 90 degree rotation. In order to shift Figure I to the location of Figure J, you must move the three figure quadrants in a clockwise direction. 3 × 90 thus equals 280 degrees. Only one transformation is needed.

Which transformation corresponds to turning a figure 90 degrees counterclockwise?

The coordinate transformation (x, y) (y, x) is equivalent to a rotation of the origin 90 degrees counterclockwise. The coordinate transformation (x, y) (x, y) is comparable to a 180 degree counterclockwise rotation of the origin.

Our point A(x,y) becomes A' when a point is rotated 90 degrees counterclockwise about the origin (-y,x). To put it another way, flip x and y, making y negative.

Step-by-step explanation:

The perimeter of the given polygon rounded to the nearest tenth is; 24.7

What is the perimeter of the Polygon?

The given polygon as we can see has 10 sides.

Now, when we draw a line from the center to the next vertex to the left of the one currently having a line, we will see that the angle can be calculated as; 360/10 = 36° because sum of exterior angles of a polygon sums up to 360°.

Thus, the other two angles will be; (180 - 36)/2 = 72° each

Using sine rule, we can find the length of a side of the polygon as;

x/sin 36 = 4/sin 72

x = (4 * sin 36)/sin 72

x = 2.472

Thus, perimeter = 2.472 * 10 = 24.72 ≈ 24.7

m∠F = 140º

1) Since that trapezoid is a quadrilateral, then we can affirm that the Sum of their interior angles is:

Note that "n" refers to the number of sides:

Notice also that angle H is a right angle since this is not an Isosceles Trapezoid

So we can write out the following

9x +14x +4x + 90 = 360º

27x = 360 -90

27x = 270

x =10

Alternatively, angles between parallel lines are supplementary

2) To find out the measure of angle ∠F We'll need to plug x=10 into that expression:

m∠F = 14x

m∠F = 140º

The area of a pool from the given situation is 816 ft².

Given that, the dimensions of plot is 50 ft and 40 ft.

The area occupied by a rectangle within its boundary is called the area of the rectangle. The formula to find the area of a rectangle is Area = Length × Breadth.

Here, area of a plot = Length × Width

= 50 × 40

= 2000 ft²

Area of a pool = Area of a plot - Area of a grass

= 2000 - 1184

= 816 ft²

Therefore, the area of a pool from the given situation is 816 ft².

The equation of the line in standard form is -1/2x + y = 1 or y = 1/2x + 1 in slope-intercept form.

(note: none of the option given is correct).

In standard form, the equation of a line can be expressed as Ax + By = C, where x and y are coordinate of a point on the line, A, B, and C are integers.

This equation can be rewritten in slope-intercept form as y = mx + b, where b is the y-intercept and m is the slope.

Given:

Substitute m = 1/2, x = 4, and y = 3 into y = mx + b to find b:

3 = 1/2(4) + b

3 = 2 + b

3 - 2 = b

1 = b

b = 1

Write the equation by substituting b = 1 and m = 1/2 into y = mx + b:

y = 1/2x + 1

Rewrite in standard form

Proved the identity sin(x) + sin(3x) = 4sin(x) cos²(x)

Given,

sin(x) + sin(3x) = 4 sin(x) cos²(x)

We have to prove the above given identity:

So,

sin(x) + sin(3x)

sin(x) + sin(2x + x)

By using the identity sin (A + B) we get,

sin(x) + sin (2x) cos(x) + cos (2x) sin(x)

Now use the identities:

sin 2x and cos 2x

We get,

sin(x) + 2sin(x) cos(x) cos(x) + (2cos²(x) - 1) sin(x)

Then,

sin(x) + 2sin(x) cos²(x) + 2sin(x) cos²(x) - sin(x)

We get,

4 sin(x) cos²(x)

Answer:

x = –1/3 and y = 11/3

or can be written as (–1/3, 11/3)

Solve the system of equations:

1x + 2y = 7

y = –2x + 3

Substitute y = –2x + 3 for y in the first equation:

1x + 2y = 7

1x + 2(–2x + 3) = 7

Substract 6 from both sides:

–3x + 6 = 7

–3x + 6 – 6 = 7 – 6

–3x = 1

Divide:

–3x/–3 = 1/–3

x = –1/3

Substitute –1/3 for x in the second equation:

y = –2x + 3

y = –2(–1/3) + 3

y = 11/3

Solution:

x = –1/3 and y = 11/3

or can be written as (–1/3, 11/3)
