Answer:

7  10  13   16

Step-by-step explanation:

a1 = 4

a6 = 19

n = 6

d = ?

a6  = a1 + (n - 1)d        

19 = 4 + (6 - 1)*d

19 - 4 = 5*d

15 = 5d

d = 15/5

d = 3

So the sequence is

4,7,10,13,16,19

Answer:

671/84 is the answer

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

64 ^1/4

What number multiply by itself 4 times  =64

m*m*m*m = 64

Rewriting 64 as 16*4

(16*4) ^1/4

We can rewrite this as

16 ^ 1/4 *  4^1/4

We know 16 ^ 1/4 = 2

2  * 4 ^ 1/4

Answer:

4

Step-by-step explanation:

64 ¼

Any number multiply by itself 4 times = 64

Let no. be x.

x × x × x × x = 64

x ⁴ = 64

Taking square root of each side

√ x⁴ = √64

x² = 8

Now, again Taking square root

√x² = √8

x = 4

Answer:

Civilization refers to a well-organized and highly cultural urban society. Urban living is based on people's freedom of self-realization, specialization and a self-organizing market economy. It has also been defined as a society where agriculture and handicrafts have developed, social strata have developed, cities and the state have emerged, writing is known and high-quality literary and artistic works are created.

The first civilizations emerged in the region of Mesopotamia, approximately 6000 years ago. For the development of these it was eminently necessary that individuals had developed cognitive and physical capacities that allowed them a correct cultural assimilation with respect to their peers, and also a correct relationship between them without the development of conflicts.

In addition, a large amount of physical and mental work was required for the development of the organization of these civilizations, both at the infrastructure level and their ideological development.

Answer:

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

Step-by-step explanation:

Hi there!

What we need to know:

1) Determine the slope (m)

[tex]x-y=5[/tex]

Rearrange this given equation into slope-intercept form. This will make it easier for us to identify the slope.

Subtract x from both sides of the equation

[tex]x-y-x=-x+5\\-y=-x+5[/tex]

Divide both sides by -1 to isolate y

[tex]y=x-5[/tex]

Now, we can identify clearly that the slope of this line is 1. Because parallel lines have the same slopes, a line parallel to this one would also have a slope of 1. Plug this into [tex]y=mx+b[/tex]:

[tex]y=1x+b\\y=x+b[/tex]

2) Determine the y-intercept (b)

[tex]y=x+b[/tex]

Plug in the given point (-5,-2)

[tex]-2=-5+b[/tex]

Add 5 to both sides

[tex]-2+5=-5+b+5\\3=b[/tex]

Therefore, the y-intercept of the line is 3. Plug this back into [tex]y=x+b[/tex]:

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

I hope this helps!

Answer:

91.19

Step-by-step explanation:

From the given diagram;

BO = 2 BC

BO = 2(48)

BO = 96

To get AB, we will use the pythagoras theroem;

BO² = AB² + AO²

96² = AB² + 30²

9216 = AB² + 900

AB² = 9216 - 900

AB² = 8,316

AB = √8,316

AB = 91.19

Hence the length of AB is 91.19

Answer: Slope is 4/3

Step-by-step explanation:  slope is change of y / change of x

k = Δy/Δx = (7-11) /(2-5) = -4 / -3 =  4/3

==========================================================

Explanation:

If the circumference is r = 12 cm, then the diameter is double that at d = 2*r = 2*12 = 24 cm.

This then leads to the circumference of C = pi*d = pi*24 = 24pi

This is exact in terms of pi. Replace pi with something like 3.14 to find its approximate value. The circumference is the distance around the circle's edge, aka perimeter.

Answer:

every parallelogram is a square? False

every rectangle with four congruent sides is a square? True

every rectangle is a quadrilateral? True

every quadrilateral is a rectangle?​ False

Step-by-step explanation:

every parallelogram is a square?

A parallelogram has two opposite pairs of parallel lines and opposite congruent sides. A square needs to have 4 right angles and all sides need to be equal. In the restrictions of a parallelogram, these cannot be concluded, therefore parallelogram are not always squares.

every rectangle with four congruent sides is a square?

Square require 4 congruent sides and 4 right angles. Rectangles already have  4 right angles. If you add 4 congruent sides to the mix, it means that these rectangles are always squares.

every rectangle is a quadrilateral?

A quadrilateral is defined by a shape having 4 sides. Rectangles have 4 sides, so they fit into the category of quadrilaterals.

every quadrilateral is a rectangle?​

A quadrilateral is a just a shape with four sides. We do not know if it has 4 right angles, so not every quadrilateral is a rectangle.

Answer:

17.6621ft²

Step-by-step explanation:

First we need to find the side length of the patio x

SInce the area of the patio = 750

Area of patio = x * x

Area of patio = x²

750 = x²

Swap

x² = 750

x = √750

x = 27.39ft

Length of the backyard = 27.39ft - 25ft = 2.39ft

Width of the backyard = 27.39ft - 20ft = 7.39ft

Area of the backyard = 2.39 * 7.39

Area of the backyard = 17.6621ft²

The dimension of the backyard is 7.4 feet by 2.4 feet. Then the area of the backyard is 17.76 square feet.

It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.

A homeowner puts a patio in the northwest corner of a square backyard. The area of the patios is 750 square feet.

The dimension of the patio will be

x² = area

x² = 750

x = 27.4 feet

The dimension of the backyard will be

Length = 27.4 – 20 = 7.4

Width = 27.4 – 25 = 2.4

The area of the backyard will be

Area of backyard = 7.4 × 2.4

Area of backyard = 17.76

Answer:

15.6km

Step-by-step explanation:

Given the map scale 1:200000

1cm on the map represents 200000 cm on ground or in actual distance

Hence, if distance from Belfast to Larne is 7.8vm on map ;

Actual distance will be :

7.8 * 200000 = 1560000 cm

Converting to km :

Recall :

1000 m = 1km

100 cm = 1 m

Hence,

100000 cm = 1km

Therefore, (1560000 / 100000) km

= 15.6km

Hence, distance between Belfast and Larne is 15.6km

Total number of children = 23

Estimate the numbers of toffees that each child will get in nearest tens.

Number of toffees each child get = Total number of toffees / Total number of children

= 975 / 23

= 42.391304347826

Approximately,

Number of toffees each child get = 40 to the nearest tens

[tex]{ \bf{y = mx + c}} \\ 2 = ( - 2 \times - 1) + c \\ c = 0 \\ \\ { \boxed{ \bf{y = - 2x}}}[/tex]

Answer:

y = -2x

Step-by-step explanation:

The equation of a line in slope intercept form

y = mx+b  where m is the slope and b is the y intercept

y = -2x +b

Using the point

2 = -2(-1)+b

2 = 2+b

Add -2 to each side

2-2 =b

0=b

y = -2x+0

y = -2x

Answer:

a reflection across line m

Step-by-step explanation:

A reflection across lime m is the final transformation of pre-image GHJK to image G'H"J"K". Option B is correct.

Reflection is defined in an atmosphere as when the beam of light or wave strikes to the plane or curved surface deviates back from the atmosphere.

The final transformation is to determine that transition states have been shown in the image that describes how pre-image GHJK transformed to image G'H"J"K".

Steps of Transformation

Pre-image GHJK first rotates anticlockwise by an angle of 90° to G'H'J'K'.

Then G'H'J'K' reflected across the line m to G'H"J"K". It is the final transition state.

Thus, a reflection across lime m is the final transformation of pre-image GHJK to image G'H"J"K".
