The required distance between given pair of points ( 2, 0 ) and ( -2,0 ) is equal to 4 units.
As given in the question,
Given pair of points in the coordinate plane is represented by the coordinates
( x₁ , y₁ ) = ( 2, 0 )
( x₂ , y₂ ) = ( -2,0 )
Apply the standard formula to calculate the distance between two pair of points in the coordinate plane is :
= √(x₂ - x₁ )² + ( y₂ - y₁ )²
Substitute the values in the formula and calculate the distance between two pair of points :
= √ ( -2 - 2 )² + ( 0 - 0 )²
= √(-4)² + 0²
= √16
= 4
Therefore, the required distance between the given pair of points ( 2, 0 ) and ( -2,0 ) is equal to 4 units.

Give a short note on triangle?A triangle is a three-sided polygon that is defined by three points in a plane, called its vertices. The three sides of a triangle are also called edges, and are connected by three angles. The sum of the angles in a triangle is always 180 degrees. There are different types of triangles, including:
Right triangle: has one angle of 90 degrees.Acute triangle: all three angles are less than 90 degrees.Obtuse triangle: has one angle greater than 90 degrees.Isosceles triangle: has two sides of the same length.Equilateral triangle: has three sides of the same length.Triangles are fundamental in mathematics and are used in many areas such as geometry, trigonometry, and engineering.
In a triangle, the measure of an angle is related to the lengths of the sides opposite and adjacent to it by the formula:
c = a/sin C
Given that c = 75 cm and mm∠C = 13°, we can use this formula to find the length of a:
a = c*sin C
where C is in radians.
a = 75 * sin(13°) = 75 * 0.2225 = 16.7 cm
Also, we know that the sum of the angles in a triangle is always 180°, so we can use that information to find the measure of angle A.
mm∠A = 180 - (mm∠B + mm∠C) = 180 - (154 + 13) = 180 - 167 = 13°
Therefore, using the Law of Sines, we can find the value of a.
[tex]\frac{a}{sin A}[/tex] = [tex]\frac{b}{sin B}[/tex] = [tex]\frac{c}{sin C}[/tex]
a = [tex]\frac{c*sin A}{sin C}[/tex]
a = [tex]\frac{75*sin(13^{0}) }{sin(154^{0}) }[/tex]
Now, you can use a calculator or a table of trigonometric values to find sin(13°) and sin(154°) and substitute them in the above equation to find the length of a. To the nearest tenth of a centimeter, a is approximately 18.6 cm.

first we subtract 92.1 from 41 which gives us 51.1 now we want to see how many hours we can keep the room for while staying under 91.1 so we divide the value of 51.1(as we have to first pay the fee of $41) by 7.3 as that is the amount they are charging per hour(51.1/7.3) which gives us 7 so we can rent the roof for 7 hours max or just for 1,2,3,4,5 or 6 hours
Are 1 4 and 2 8 equivalent fractions?.
Yes, 1/4 and 2/8 equivalent fractions.
Mathematical fractions that have the same denominator but different numerators are called equivalent fractions. As an illustration, since 2/4 and 3/6 both equal 1, they are both comparable fractions. The total is divided into fractions. When referring to identical components of the total, equivalent fractions are utilized.
By multiplying the numerator and denominator by the same integer, it is possible to determine the equivalent fraction of each fraction. In spite of differences in appearance, equivalent fractions signify the same value.

Rachel's non-brokerage fee-related closing costs can be calculated by subtracting the brokerage fee from her total closing costs.
Since the brokerage fee was 6%, the fee comes out to be $1,105.20. To calculate the non-brokerage-related closing costs, subtract $1,105.20 from the total closing costs of $18,427, which yields a total of $17,321.80.
18427-1105.20=17321.80
This is the amount of non-brokerage fee-related closing costs that Rachel paid for her home. Rachel's net gain from the sale of her home was $230,063, which is the difference between the sale price of her home and the total closing costs, including the brokerage fee.

Akio draws a graph to record the distance he rides on a long bike ride. What is the slope of the line for the first two hours? What is the slope of the line for all five hours? What does the slope mean in this situation?
Answer:
Below
Step-by-step explanation:
To find the slope of a line, we use the formula:
slope = (change in y-coordinates) / (change in x-coordinates)
In this case, if Akio recorded the distance he rode on his bike ride in hours, the slope of the line for the first two hours would be the change in the y-coordinates (distance) divided by the change in the x-coordinates (time) between those two points.
To find the slope of the line for all five hours, we will need to know the specific coordinates of all five points, otherwise, it's impossible to calculate the slope.
The slope of a line represents the rate of change in the y-coordinates (distance) per unit of change in the x-coordinates (time). In this situation, the slope represents Akio's speed, since the change in distance is divided by the change in time. A positive slope indicates an increase in distance over time, which means Akio is getting faster, whereas a negative slope indicates a decrease in distance over time, which means Akio is getting slower.
It's worth noting that a slope of zero would mean that there is no change in distance over time, which would mean that Akio isn't moving.

The equation that shows how the price of a personal pizza y depends on the number of toppings x is y = 7 + x.
The equation of a straight line is an equation that comes in the form of an algebraic equation. It is also referred to as Slope - Intercept form. It can be represented using the equation below:
Equation : y = mx + c
where:
m = Gradient
c = Slope of the line
The equation that shows how the price of a personal pizza y, depends on the number of toppings x is y = 7 + x
This question can be solved and represented using the equation of a straight line.
Let's represent
y = price of a personal pizza
x = number of toppings
The price for a plain cheese pizza = $7
The price for each of the toppings = $1
Therefore, the equation that shows how the price of a personal pizza y, depends on the number of toppings x is written as:
y = $7 + $1 × x
y = 7 + x
Therefore, y = 7 + x is the equation represents the relationship between the price of a personal pizza and the amount of toppings.
