Can someone please solve these? Identify the segment bisect of XY. Then find XY

Answer:

Vertical: x = 1

Horiz: y = 8

Step-by-step explanation:

The equation of a

vertical line is always:

x = anumber

The equation of a horizontal line is in the form:

y = anumber

In the question a point is given, the point (1,8) is in the form (x,y) So x is 1 and y is 8.

We can fill in this given information to complete the equations.

Vertical: x = 1

Horizontal: y = 8

By solving the inequality we get [tex]y\leq -3[/tex]

What is graphing the inequality?

The act of illustrating which area of the number line contains values that will "satisfy" the specified inequality is known as graphing the inequality. Take a look at the first inequality, "x > -5." The numbers that can be used to substitute x in our inequality to produce a true statement can be shown on a graph of our inequality.

Natalie will be paid $656.61 for a week and for summer $10505.76.

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given that Natalie earns $15.27 per hour while working as a playground supervisor for 8 weeks throughout the summer. Although she works a 40-hour week, she typically puts in 3 hours of overtime.

For a week = ( 40 + 3 ) x 15.27 = $656.61

For a summer = 4 x 4 = 16 weeks

For a summer = 16 x $656.61 = $10505.76

Therefore, Natalie will be paid $656.61 for a week and for summer $10505.76.

The value of QR when points P, Q, R and S are collinear is .13

We are given that:

Points P, Q, R and S are collinear points.

Also,

PS = 23

PR = 18

We need to find the value for QR.

Now, we have that PQ is congruent to RS.

So, This means that PQ = RS

This can also be written as:

PR - QR = RS

18 - QR = RS

Also,

PR + RS = PS

Substituting the values, we get that:

18 + ( 18 - QR ) = 23

18 - QR = 23 - 18

18 - QR = 5

QR = 18 - 5

QR = 13

Therefore, we get that, the value of QR when points P, Q, R and S are collinear is .13

Using the definition of slope, the triangle with vertices (3 , 5), (-2 , 6), and (1 , 3) is a right triangle.

The slope, m, determines the steepness of a line. It can be measured by the vertical distance from one point to another divided by the horizontal distance of the same points.

m = (y2 - y1)/(x2 - x1)

To prove that the triangle with vertices (3 , 5), (-2 , 6), and (1 , 3) is a right triangle, there should be a pair of adjacent lines perpendicular with each other(forms 90 degree angle). The slope of this pair of adjacent lines must be negative reciprocal of one another.

let A = (3 , 5)

B = (-2 , 6)

C = (1 , 3)

Determine the slope of each line of the triangle: AB, BC, AC.

AB : m = (6 - 5)/(-2 - 3) = 1/-5 = -1/5

BC : m = (3 - 6)/(1 - -2) = -3/3 = -1

AC : m = (3 - 5)/(1 - 3) = -2/-2 = 1

-1 is the negative reciprocal of 1. The slope of BC is the negative reciprocal of the slope of AC, hence, side BC is perpendicular with each other.

Therefore, the triangle with vertices (3 , 5), (-2 , 6), and (1 , 3) is a right triangle.

The distance from the center of a circle to a point in the interior of a circle is always less than radius of the circle.

It is given that there is a point inside the circle.

We have to find that whether its distance from center of circle is sometimes, always, or never less than the radius of the circle.

What is the radius of a circle ?

The distance between the center of a circle and any point on the circle is called the radius of circle.

We know that ;

Radius is the distance between the center of a circle and any point on the circle.

Let's assume three points which are A, B, and C, where A is a point inside circle, B is a point on circle, and C is a point outside circle.

Also ;

O is the center of circle.

So ;

OA = the length of the line from center to point inside the circle.

OB = radius of the circle.

OC = the length of the line from center to the point outside the circle.

So ;

We can conclude that ;

OA<OB<OC.

or

The length of the line from the center of a circle to any point inside the circle will be always less than it's radius.

Thus , the distance from the center of a circle to a point in the interior of a circle is always less than radius of the circle.

The required error in Caroline's quadratic equation in vertex form by completing the square is -2(x² - 6x + 9) - 9 - 15 is should be -18 in place of -9.

Given that,
To figure out the error made by Caroline in the calculation of a quadratic equation in vertex form by completing the square.

His calculation,
= -2x² + 12x - 15

= -2(x² - 6x) — 15

= -2(x² - 6x + 9) - 9 - 15-2(x - 3)²9 - 15
= -2(x - 3)² - 24

Correct calculation,
= -2x² + 12x - 15
= -2(x² - 6x) - 15

= -2(x² - 6x + 9) - 18 - 15
= -2(x - 3)² - 18 - 15
= -2(x - 3)² - 33

The correlation coefficient is simply the specific measure that quantifies the strength of the linear relationship between two variables in a correlation analysis. It varies from -1 to 1.

Now, we are told that the correlation coefficient is 0.93. This means that it is close to 1. Now, we know that when the correlation coefficient is near 1 or −1, the linear relationship is strong; when it is near 0, the linear relationship is weak.

We also know that correlational studies allow researchers to detect the presence and strength of a relationship between variables, while experimental studies allow researchers to look for cause and effect relationships.

When two sides are provided without an angle measurement, such as a = 13m and b = 17m , we can create an infinite number of obtuse triangles.

As an example:

How many different obtuse triangles can we make if our side lengths are 13m and 17m, and our angle value ranges from 90 to 360 degrees?

Make a triangle with sides of 13m and 17m metres, a 120 degree angle, and a third side that can be protractored to the length you desire. You've constructed a triangle.

We may create a whole different triangle that is identical to this one by altering the third side's length and angle.

You must always remember to select the side lengths and angles. It's hinted that you could choose another course of action. There are an infinite amount of distinct triangles that can be created by using the same angles.
