An example of a graph with 4 vertices, with at least one vertex having a degree of 1 is a square graph.

There are 11 simple graphs on 4 vertices.

A graph is a set of points, known as vertices, and lines between those points are referred to as edges. there are many exclusive styles of graphs, along with linked and disconnected graphs, bipartite graphs, weighted graphs, directed and undirected graphs, and simple graphs.

This sort of graph with an even wide variety of vertices of diploma 4 has an even length, so our graphs must have 1, three, or 5 vertices of degree four. as much as isomorphism, there is precisely one graph of each type. A related graph G is known as a Hamiltonian graph if there's a cycle that includes each vertex of G and the cycle is referred to as a Hamiltonian cycle.

Step-by-step explanation:

a linear function must follow the structure

y = ax + b

we use the given data point numbers for x and y to solve for the 2 variables a and b.

we use 2 data points to get a solution for the 2 variables. if the third data point then fits into the same equation, then all 3 points are on a line, and the function is therefore linear. if not, then not.

-8 2/5 = a×-7 1/2 + b

-6 = a×-1 1/2 + b

let's subtract the second from the first equation to eliminate b and solve for a :

-8 2/5 = a×-7 1/2 + b

- -6 = a×-1 1/2 + b

----------------------------------

-2 2/5 = a×6 0

6a = -2 2/5 = (-2×5 - 2)/5 = -12/5

a = -12/5 / 6 = -2/5

and now we use one of the 2 original equations with the newly found information to solve for b :

e.g.

-6 = -2/5 × -1 1/2 + b = -2/5 × -3/2 + b = 6/10 + b = 3/5 + b

-6 - 3/5 = b

(-6×5 - 3)/5 = b

-33/5 = b

so, our proposed linear function is

y = -2x/5 - 33/5

let's see, if the third point is on the line (then the equality is true for its coordinates) or not :

-2 = -2/5 × 8 1/2 - 33/5 = -2/5 × (8×2 + 1)/2 - 33/5

-2 = -2/5 × 17/2 - 33/5 = -34/10 - 33/5 = -34/10 - 66/10

-2 = -100/10 = -10

that is not true (-2 is not equal to -10), so the third point is not on the line between the first 2 points.

that means the function is nonlinear.

Answer:

  C) The circumcenter is on the outside of an obtuse triangle.

Step-by-step explanation:

You want to know where the circumcenter is in relation to the sides and vertices of different triangles.

The circumcenter of a triangle is the center of the circle through its vertices. As such, it will never lie on a vertex of the triangle.

As you can see in the attached figure, the circumcenter of an acute triangle is inside the triangle.

For a right triangle, the circumcenter is the midpoint of the hypotenuse.

The circumcenter of an obtuse triangle is outside the triangle.

__

Additional comment

The circumcenter is located at the point where the perpendicular bisectors of the sides meet.

For dilation, a figure's size and shape only change during transformation, but during translation, the size of the figure's image and preimage are congruent.

Congruent in geometry refers to being the same size and shape. Congruence can be used with figures, angles, and line segments. If any two line segments are equal in length, they are said to be congruent. If two angles have the same measure, they are said to be congruent.

Techniques for transformation: In a xy-plane, transformation involves changing the size and shape of an item.

Translation and dilation are a couple of the transformation methods used.

For dilation, a figure's size and shape only change during transformation, but during translation, the size of the figure's image and preimage are consistent.

The area of a parallelogram is:

a = bh

The base, b, of the parallelogram is 14.

The issue with this particular figure? We need the perpendicular height. We are given the side width, but that cannot be used in the final equation. So, we employ the Pythagorean Theorem.

We know that in the right triangle, a = 4, and c = 8.

a^2 + b^2 = c^2
4^2 + b^2 = 8^2
16 + b^2 = 64
16 - 16 + b^2 = 64 - 16
b^2 = 48
√b^2 = √48
b ≈ 6.93

So, b in this right triangle is equal to h in the parallelogram. So:

a ≈ 14(6.93)
a ≈ 97.02

After decreasing £16870 by 3% we get, £16363.90

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%".

First, find the percentage of £16870 by 3%

%value = 3% * 16870

            = (3 / 100) * 16870

            = 506.1

Now, just minus with actual value

New value = actual value - %value

We know, actual value = £16870 and %value = 506.1

so, New value = 16870 - 506.1

we get, New value = £16363.90

Therefore, After decreasing £16870 by 3% we get, £16363.90

We proved that [tex]\angle2\cong\angle4[/tex].

Given: [tex]\angle2[/tex] and [tex]\angle4[/tex] are vertical.

We have to prove [tex]\angle2\cong\angle4[/tex]

The [tex]\cong[/tex] means congruence which means [tex]\angle2[/tex] and [tex]\angle4[/tex] both have same size and angle. We have to show that they both have same size or angle to prove them congruence.

As we know that the value of straight line is [tex]180^{o}[/tex].

From the given figure we can see that

[tex]\angle1+\angle2=180^{o}[/tex]

[tex]\angle3+\angle4=180^{o}[/tex]

[tex]\angle1+\angle4=180^{o}[/tex]

[tex]\angle2+\angle3=180^{o}[/tex]

To prove the [tex]\angle2\cong\angle4[/tex] we subtract [tex]\angle1+\angle2=180^{o}[/tex] and [tex]\angle1+\angle4=180^{o}[/tex]

[tex]\angle1+\angle2-(\angle1+\angle4)=180^{o}-180^{o}[/tex]

We first simplify bracket. When we multiply with the subtraction sign then the sign under the bracket will changed.

[tex]\angle1+\angle2-\angle1-\angle4=0[/tex]

There have [tex]\angle1[/tex] in addition and subtraction then there only remains

[tex]\angle2-\angle4=0[/tex]

We can write that notation as

[tex]\angle2=\angle4[/tex]

Since [tex]\angle2=\angle4[/tex], that means they both have same angle.

Cost of the TV before sale £350

We come across phrases like cost price, tagged price, discount, and selling price when making a purchase. Shop owners give discounts to customers to encourage product sales. Discount is the term used to describe a rebate or an offer made to clients on the listed price of goods. Let's examine the connections between these concepts.

Given,

Sale% = 20%

The cost of TV after the sale = £280

Finding the original price:

                   100% - 20% = 80%

So 80% is the price £280

We have to find the 20% which has been less

Or, £280 = 0.80 x T

Let the original price be T,

                               280 = 0.80 x T

                               280/0.80 = T

                                      350 = T
