Based on the given graph and line, the distance between the pair of points is 5
How to find the distance between a pair of points?To find the distance between two points on a line or a pair of points, first find the coordinates of the points:
(-1, -2) and (-1, 3)
The distance then be found by applying the formula:
=√((x2 – x1)² + (y2 – y1)²)
Solving for the distance gives:
=√((-1 – (-1))² + (3 – (-2))²)

The ratio of the weight of max to that of his friend artur is 5:9. artur goes on a diet and lose 4kg and now the ratio of their weights is 5:7. how much does artur weigh now?
After losing 4 Kg ,the weight of Artur is 14 Kg .
In the question ,
it is given that ,
the ratio of weight of Max : Artur is 5 : 9 .
So the weights of Max and Artur before dieting is 5x and 9x .
Now Artur goes on dieting and lose 4 Kg weight and
the ratio of weight of Max and Artur becomes 5:7 .
and the weights of Max and Artur after dieting is 5x and 7x .
Present weight of Artur = 7x .
As we can see that the change in Artur weight is 9x - 7x = 2x
According to the question
2x = 4
x = 2
hence Artur now weighs 7*(2) = 14 Kg
Therefore , after losing, 4 Kg the weight of Artur is 14 Kg .

A pizza shop offers a choice of 3 sizes (small, medium, and large) and 7 different toppings. Different pizzas can be created by changing the size and/or the choice of toppings. If Cody wants to order a pizza with exactly 2 different toppings, how many different pizzas can he create?
1. 6
2. 21
3. 63
4. 121
Using permutation and combination we can calculate that she can get 63 different types of pizza.
Permutations and combinations are the various ways in which elements from a set may be chosen, typically without replacement, to create subsets. This choice of subsets is known as a permutation when the order of the selection is taken into account, and as a combination when it is not.
The total of the decisions we make given an initial set of n items is known as a combination. Permutation, on the other hand, counts the number of possible arrangements of n separate items. This will help us recall that combinations place more emphasis on choice than on placement, order, or arrangement.
Now Cody can get any two toppings out of the 7.
Number of ways in which Cody can pick 2 toppings out of 7 is given by the use of combination,
7C2 = 21 different ways.
Again the number of ways in which 3 different pizza s can be selected is given by 21 × 3 = 63 ways.
Hence Cody can create 63 different pizzas.

find the measure of each interior angle and each exterior angle of a regular 12 -gon (a twelve-sided polygon).
Answer:
interior = 150° , exterior = 30°
Step-by-step explanation:
the sum of the exterior angles of a polygon = 360°
since the polygon is regular then each exterior angle is
360° ÷ 12 = 30°
the sum of the exterior angle and interior angle = 180° then
interior angle = 180° - 30° = 150°

By solving a simple linear equation, we will get that:

How to find m∠AOB?
We can write a simple linear equation here, we know that:
m∠AOC = 108°
And we also know that:
m∠AOC = 3*m∠AOB
If we replace the first equation into the second one, then we will have the linear equation:
108° = 3*m∠AOB
And we want to solve this for m∠AOB, to do so, we just need to divid both sides by 3, we will get:
108°/3 = m∠AOB
36° = m∠AOB

Vertex
The quadratic equation has a vertex at point (3, 1).
Axis of symmetry
The axis of symmetry of the parabola is x = 3.
Min/Max value
For as the vertex constant is a negative number, then the vertex represents a maximum. Then, we evaluate the function at x = 3:
f(3) = 1
y-Intercept
The y-intercept is the value of the quadratic equation evaluated at x = 0.
f(0) = - (0 - 3)² + 1
f(0) = - 9 + 1
f(0) = - 8
x-Intercepts
The x-intercepts are the values of x such that f(x) = 0, all these can be found by using algebra properties:
- (x - 3)² + 1 = 0
- (x² - 6 · x + 9) + 1 = 0
- x² + 6 · x - 9 + 1 = 0
x² - 6 · x + 8 = 0
(x - 2) · (x - 4) = 0
Then, the x-intercepts of the parabola are (2, 0) and (4, 0).
Domain
The domain of all quadratic equations are all real numbers.
Range
Since the vertex constant is negative, the range of the quadratic equation is the subset of all real numbers equal or less than the y-value of the vertex.

The integer in the solution set of 5/6m - 4 < 1/3m + 5 that would make it false is 20
How to determine the integers in the set?The set is given as
S:{−18, 2, 15, 20}
The inequality expression is given as
five sixths m minus four is less than one third m plus 5
Rewrite the inequality expression properly
So, we have
5/6m - 4 < 1/3m + 5
Subtract 1/3m from both sides of the inequality expression
So, we have
1/2m - 4 < 5
Add 4 to both sides of the inequality expression
So, we have
1/2m < 9
Divide both sides of the inequality expression hy 1/2
So, we have
m < 18
This means that the integers in the solution set are integers that are less than 18
These integers are −18, 2, 15
All other integers would make the inequality false

Omar has been training for the Candlewood Footrace. The first week he trained, he ran 7 days and took the same two routes each day: 3 miles around the track before work and a longer route through his neighborhood after work. By the end of the week, Omar had run a total of 63 miles.
Which equation can you use to find how many miles, x, Omar ran each day after work?
The equation that can be use to find the how many miles, x, Omar ran each day after work is x = (Total distance he ran in one week - The total distance he run before the work in one week) ÷ 7, he ran 6 miles each days after work
The total number of days he run = 7 days
Total distance he ran in one week = 63 miles
The distance he run before the work = 3 miles
The total distance he run before the work in one week= 7×3
= 21 miles
The total distance he run after the work = 63 - 21
= 42 miles
The equation that can use to find how many mile x, Omar ran each day after work = (Total distance he ran in one week - The total distance he run before the work in one week) ÷ 7
Substitute the values in the equation
= 42/7
= 6 miles

Find the slope and write an equation of the line which passes through the points.
A
(5,6) and (3,4)
The slope and equation of line with the coordinates (5,6) and (3,4) are 1 and y = x + 1 respectively.
How determine the slope of a line segment line?Slope is simply expressed as change in y over the change in x.
Slope m = ( y₂ - y₁ )/( x₂ - x₁ )
Given the data in the question;
Point A(5,6)
x₁ = 5y₁ = 6Point B(3,4)
x₂ = 3y₂ = 4Slope m = ?
To determine the slope, plug the given coordinates into the slope formula and simplify.
Slope m = ( y₂ - y₁ )/( x₂ - x₁ )
Slope m = ( 4 - 6 )/( 3 - 5 )
Slope m = ( -2 )/( -2 )
Slope m = ( -1 )/( -1 )
Slope m = 1/1
Slope m = 1
Next, use the the formula for the equation of line to determine the y-intercept 'b'.
y = mx + b
Plug in slope m = 1 and point (5,6)
6 = 1(5) + b
6 = 5 + b
b = 6 - 5
b = 1
Now that we have both the slope m ( 1 ) and y-intercept b ( 1 ), plug these values into y = mx + b to find the linear equation.
y = mx + b
y = 1x + 1
y = x + 1
Therefore, the slope is 1 and equation of line is y = x + 1.

Here, we are given that the volume of a box is 216 cm cube.
Here, we assume that the box is a cube and not a cuboid since only then we will be able to find the edge of the box.
The volume of a cube is given by the formula-
Volume = side × side × side
Let the side of the given cube be x.
Then we can form the following equation-

Identify the zeros of the functions.
1. y = 5(x - 3)(x + 5)
2. y = (x - 7)^2
Help with these problems above would be greatly appreciated, thanks!
Answer:
1. 3 and -5
2. 7
Step-by-step explanation:
The zeros of functions are the x-values when y = 0, i.e the point(s) at which the line crosses the x-axis.
To find the zeros of the given functions, set the function to zero and solve for x.
Question 1Given function:
[tex]y=5(x-3)(x+5)[/tex]
Set the function to zero:
[tex]\implies 5(x-3)(x+5)=0[/tex]
[tex]\implies \dfrac{5(x-3)(x+5)}{5}=\dfrac{0}{5}\\[/tex]
[tex]\implies (x-3)(x+5)=0[/tex]
Using the Zero Product Property, set each factor equal to zero and solve for x:
[tex]\implies (x-3)=0 \implies x=3[/tex]
[tex]\implies (x+5)=0 \implies x=-5[/tex]
Therefore, the zeros of the function are 3 and -5.
Question 2Given function:
[tex]y=(x-7)^2[/tex]
Set the function to zero and solve for x
[tex]\implies (x-7)^2=0[/tex]
[tex]\implies \sqrt{(x-7)^2}=\sqrt{0}[/tex]
[tex]\implies x-7=0[/tex]
[tex]\implies x=7[/tex]
Therefore, the zero of the function is 7 (with multiplicity 2).
