The point of concurrency which is not always inside a triangle is circumcenter and orthocenter.

We are given that;

The four options

Now,

A point of concurrency is a single point shared by three or more lines1. In a triangle, there are four points of concurrency that are associated with different types of line segments: centroid, incenter, circumcenter and orthocenter.

The centroid is the point of concurrency of the medians of a triangle, which are the line segments that connect the midpoints of the sides to the opposite vertices. The centroid is always inside the triangle.

The incenter is the point of concurrency of the angle bisectors of the triangle, which are the line segments that divide the angles into two equal parts. The incenter is also always inside the triangle.

The circumcenter is the point of concurrency of the perpendicular bisectors of the sides of the triangle, which are the line segments that are perpendicular to the sides and pass through their midpoints.

The circumcenter can be inside or outside the triangle, depending on the type of triangle. For an acute triangle, it is inside; for a right triangle, it is at the midpoint of the hypotenuse; for an obtuse triangle, it is outside

Therefore, by triangle the answer will be circumcenter and orthocenter.

Answer:

[tex]2b^{2}[/tex] + 4b - 8

Answer:

[tex]\sqrt{202}[/tex] units or 14.2 units (rounded to the nearest tenth)

Step-by-step explanation:

To find the distance between a pair of two points, use the distance formula  [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]. Substitute the x and y values of (-1,-2) and (8,9) into the formula and simplify:

[tex]d = \sqrt{(-1-8)^2+(-2-9)^2} \\d = \sqrt{(-9)^2+(-11)^2} \\d = \sqrt{81+121} \\d= \sqrt{202}[/tex]  

So, as an exact answer, the distance is [tex]\sqrt{202}[/tex] units.

(To find the decimal approximate of that answer, enter it into a calculator. This would make the decimal approximate 14.2 units, when rounded to the nearest tenth.)  

Answer:

14.2

Step-by-step explanation:

All you need to do is plug the coordinates into the distance formula.

√(x2 - x1)² + (y2 - y1)²

√[8 - (-1)]² + [9 - (-2)]²

√(9)² + (11)²

√81 + 121

√202

= 14.2

the interest that would he owe at the end of the two years is $880

Step-by-step explanation:

The computation of the interest that would be owe at the end of two years is shown below

here we applied the simple interest formula

Answer:

m∠BAC = 52°  or theta = 52°

Step-by-step explanation:

I am guessing that you are trying to find m∠BAC ( which is theta)

(1)  The measure of an inscribed angle is 1/2 the measure of the intercepted arc

measure of arc BC is twice the measure of ∠CDB

measure of arc BC = 2(26) = 52

(2)  The measure of a central angle equals the measure of the intercepted arc.

m∠BAC = 52°

Note:  You need to remember statements (1) and (2) to help you with this type of problem.  OK?

The graph of the given equation is attached to the solution.

In math, a graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.

Given is an equation, 1.5x+2y = 3 we need to graph it,

So, first finding the coordinates,

1.5x+2y = 3,

Put x = 0

y = 1.5 [0, 1.5]

Put y = 0

x = 2 [2, 0]

Putting the coordinates on the graph and connect them, the line obtained will be the graph of the equation,

Since, the equation is linear the graph will be a straight line,
