Circumcenter of Triangle:

The circumcenter of a triangle is defined as the point where the perpendicular bisectors of the sides of that particular triangle intersect. The parallel points of the bisectors of a triangle are called the circumcenter. This is represented by P(X,Y). The circumcenter is also the center of the triangle's circumcircle, which can be either inside or outside the triangle.

Line Segment:

In geometry, a line segment is a portion of a straight line bounded by two different endpoints and includes all points on the line between the endpoints. The length of the line segment is determined by the Euclidean distance between the endpoints. A closed line includes both endpoints, but an open line does not. A half-open line contains only one endpoint. In geometry, line segments are often denoted by lines over two endpoint symbols.

Examples of line segments are the sides of triangles or squares. More generally, if both endpoints of a segment are vertices of a polygon or polyhedron, the line segment is either an edge (of that polygon or polyhedron) if the vertices are adjacent, or a diagonal line . If both endpoints are on a curve (such as a circle), the line segment is called a chord (of that curve).

Option D: The solution of the system of equation is (-1,-2)

A group of equations comprising one or more variables is known as a system of equations. The variable mappings that satisfy each component equation, or the points where all of these equations cross, are the solutions of systems of equations.

A finite collection of equations for which common solutions are sought is referred to as a set of simultaneous equations, often known as a system of equations or an equation system.

To create an equation in one variable using the elimination approach, you may either add or subtract the equations. To remove a variable, add the equations when the coefficients of one variable are in opposition, and subtract the equations when the coefficients of one variable are in equality.

The equations are :

y = 3x + 1 ⇒ y - 3x = 1 (i)

y = -2x -4 ⇒ y + 2x = -4  (ii)

Subtracting (i) from (ii) we get ,

2x +3x = -4 -1

The x values after solving the equation |2x - 5| = |7x + 10| are -3 and [tex]\frac{-5}{9}[/tex].

As per the given data, the given equation is:

|2x - 5| = |7x + 10|

Here we have to solve the given equation.

Which means we have to find the value of x.

|2x - 5| = |7x + 10|

Remove the mod on either side of the equation.

When we remove mod ± should be added to another side of the equation.

We get:

2x - 5 = ± (7x + 10)

When it is positive, we get:

2x - 5 =  (7x + 10)

7x - 2x = -5 - 10

5x = -15

x = -3

When it is negative, we get:

2x - 5 = - (7x + 10)

2x - 5 = -7x - 10

2x + 7x = -10 + 5

9x = -5

The value of the first term that is less than 0 is -4

The formula for the nth term of an arithmetic sequence is:

aₙ = a₁ + (n - 1)d

Where a₁ is the first term in the sequence, d is the common difference between terms, and n is the position of the term that we are trying to find.

If in an arithmetic sequence, the first term is 100 and the fourth term is 76, then the common difference is

aₙ = a₁ + (n - 1)d

76 = 100 + (4 - 1)d

76 = 100 + 3d

3d = 76 - 100

3d = -24

d = -8

Solve for aₙ that is less than 0.

aₙ = a₁ + (n - 1)d

aₙ = 100 + (n - 1)(-8) < 0

100 - 8n + 8 < 0

8n > 108

Quartiles (Quartiles are the most prevalent percentiles. Data sets are divided into quadruples, or four equal sections, by quartiles. The bottom 25% of the data are separated from the top 75% by the first quartile, abbreviated Q1. The first quartile therefore corresponds to the 25th percentile. The second quartile, or Q2, separates the bottom 50% of the data from the top 50%; it is corresponding to the median or 50th percentile.

The SAS congruence states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

First, let's take two triangles ABC and DEF. If the side lengths of both triangles are the same (AB = DE, AC = DF) and the included angle (angle A) is the same in both triangles (angle A = angle D) then the two triangles are congruent. This is known as the SAS congruence.

To prove the SAS congruence, we can use the Law of Congruent Triangles. This law states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

To prove this, we can use the Side-Angle-Side Postulate. This postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then the two triangles are congruent.

This means that if the side lengths of both triangles are the same (AB = DE, AC = DF) and the included angle (angle A) is the same in both triangles (angle A = angle D) then the two triangles are congruent. This is known as the SAS congruence.

Based on a scale factor of 1 inch to 100 feet, the length of the model of the bridge is equal to: D. 89.8 inches.

In Geometry, a scale factor can be defined as the ratio of two corresponding side lengths or diameter in two similar geometric figures such as bridges, which can be used to either horizontally or vertically enlarge (increase) or reduce (decrease or compress) a function that represents their size.

Mathematically, the scale factor of a geometric object can be calculated by dividing the dimension of the image by the dimension of the pre-image (original figure).

Substituting the given parameters into the scale factor formula, we have the following;

Length of model bridge = 8980/100

Length of model bridge = 89.8 inches.

In this context, we can reasonably infer and logically conclude that the model bridge's length is equal to 89.8 inches.
