Answer
[tex] \boxed{10 \: \: units}[/tex]
Step by step explanation
Let the points be A and B
A ( 5 , 1 ) ⇒ ( x₁ , y₁ )
B ( -3 , -5 )⇒ ( x₂ , y₂ )
Now, let's find the distance between theses two points:
Distance = [tex] \mathsf{ \sqrt{ {(x2 - x1)}^{2} + {(y2 - y1)}^{2} } }[/tex]
Plug the values
[tex] \mathsf{ \sqrt{ {( - 3 - 5)}^{2} + {( - 5 - 1)}^{2} } }[/tex]
Calculate
[tex] \mathsf{ \sqrt{ { ( - 8)}^{2} + {( - 6)}^{2} } }[/tex]
Evaluate the power
[tex] \mathsf{ \sqrt{64 + 36} }[/tex]
Add the numbers
[tex] \mathsf{ \sqrt{100} }[/tex]
Write the number in exponential form with a base of 10
[tex] \mathsf {\sqrt{ {10}^{2} } }[/tex]
Reduce the index of the radical and exponent with 2
[tex] \mathsf{10 \: units}[/tex]
-------------------------------------------------------------------------------
The distance formula is used to determine the distance ( d ) between two points. If the co-ordinates of the two points are ( x₁ , y₁) and ( x₂ , y₂ ) , the distance equals the square root of x₂ - x₁ squared + y₂ - y₁ squared.

If a polygon has an area of 10 cm² and is dilated by a factor of 2, what will be the area of the dilated polygon?
Area depends on the product of sides,
so if the sides are shortened by a factor of 2, area will reduce by a factor of 4. (2×2)
new area = 10/4=2.5 cm²
According to Hooke's Law, the force needed to stretch a spring varies directly to the amount the spring is stretched. If 50 pounds of force stretches a spring five inches, how much will the spring be stretched by a force of 180 pounds? inches
The length a spring stretches when subjected to the given load is required.
The spring is stretched by 18 inches.
Hooke's lawF = Force
k = Spring constant
x = Stretched length

What is the factored form of 125x6 – 8?
Answer:
Step-by-step explanation:
125 = 5 *5 * 5 = 5³
8 = 2 * 2 *2 = 2³
125x⁶ - 8 = 5³(x²)³ - 2³
= (5x²)³ - 2³ { a³ - b³ = (a -b)(a² + ab + b²)

Mai says that the glow necklace is 24 inches. 1. Do you think that all these circles are the same size? 2. What part of the circle did each person measure? Explain your reasoning.
Answer:
Yes they are of the same size since they have the same number and standard unit of measurement (i.e 24 inches).
Each person measures the circumference of the circle.
Step-by-step explanation:
Given that :
Priya, Han, and Mai each measured one of the circular objects from earlier.
Priya says that the bike wheel is 24 inches.
Han says that the yo-yo trick is 24 inches.
Mai says that the glow necklace is 24 inches.
Do you think that all these circles are the same size?
Yes they are of the same size since they have the same number and standard unit of measurement (i.e 24 inches).
What part of the circle did each person measure?
Each person measures the circumference of the circle.
The circumference also known as the perimeter of the circle is denoted by :
C = 2π r
The circumference of a circle is the distance round the edges of the circle.
Given that C = 24
24 = 2π r
r = 24/(2π)
r = 3.8 inches
This confirms the claim that all the circle are of the same size since they possess the same radius.
Answer:
The person who answered first is WRONG
Step-by-step explanation:
I did this and these are the answers the teacher gave me:
the circles are NOT the same size

Answer:
Description of the given points can be defined as follows:
Step-by-step explanation:
In points A, If b is less than a and c. so, it calls the smiley face (a, b , c), so we'll have a smiling smile whenever we create a chart! And if b is bigger then a and c, then it should be an angry face, although when we switch the head inside out, they get a grumpy face.
In point b, the smirks, which including a greater than b and c, then it is the neutral faces like a is equal to and b equal to c , it can also be seen in certain forms of faces. When the facial is positive, therefore b and b is similar to c. because when we pick a, b and c, but there's a choice of n are neutral.
Its quantity of scowls has been counted. There are many n options to choose a or n-1 forms of picking b. Each value that we can choose for the could also have been the price of b or c. There is also multiplication by 3. Thus 3n(n-1) scowls were present.
A number of happy face faces we note now. There will be n options for such a then n – 1 options for b, but n – 2 options for c. There were the happy faces of n(n-1)(n-2) = 3C(n,3). There are many grumpy face faces of the configuration of 3C(n,3).
Thus, n^3 = n + 3n(n – 1)+ 6C(n,3) was its total amount of faces.
(b) We can select two groups of 2 categories one at two numbers to choose three numbers and the other with one group. Its total number of n+2 can be divided into two groups.
First, there are many two numbers with one group, then n number in another one. This makes up n + 2 number of all. C(2,2) = 1 represents selecting two digits from the two sets. There are many C(n,1) = n forms to select a single organization amount. Which offers us a first 1*n term.

Ms. Mitchell brings in 700 sour worms to distribute to the students at ... /1
her school. She gives 2/7 of the worms to the Kindergartners. Of the
remaining worms, she gives 7/25 to the 1st graders. Of the remaining
worms, she gives 4/9 to the 2nd graders. Of the remaining worms, she
gives 37/50 to the 3rd graders. Ms. Mitchell then distributes the
remaining worms evenly between the 4th graders. If there are 13 4th
graders, how many worms does each 4th grader get?
================================================
Explanation:
We'll step through the grade levels in increasing order
The teacher starts with 700 sour worms total. Then 2/7 of that is given to the Kindergartners
2/7 of 700 = (2/7)*700 = 200
So Ms. Mitchell handed out 200 worms to the Kindergartners.
This means she has 700-200 = 500 left over.
-----------------
Now onto the 1st graders.
The teacher hands out 7/25 of the remaining total (500) to the first graders
7/25 of 500 = (7/25)*500 = 140
She hands out 140 worms to the first graders and has 500-140 = 360 worms left.
-------------------
Now the 2nd graders
"Of the remaining worms, she gives 4/9 to the 2nd graders" tells us that
4/9 of 360 = (4/9)*360 = 160 worms are given to the second graders
This leaves 360-160 = 200 worms left
-------------------
Now the 3rd graders
37/50 of 200 = (37/50)*200 = 148
The teacher hands out 148 worms to the 3rd graders
There are 200 - 148 = 52 worms left.
--------------------
Finally, we're at the 4th graders
Each 4th grader gets the same number of worms (aka the amount is distributed equally). Since there are 52 worms left, and 13 fourth graders, this means each fourth grader gets 52/13 = 4 worms. It's a slightly interesting coincidence that the number '4' matches up with the grade level. It's possible your teacher adjusted the numbers to make this an intentional goal.
--------------------
To recap everything, we found these worm counts for each grade level
Kindergarten = 200 wormsFirst graders = 140 wormsSecond graders = 160 wormsThird Graders = 148 wormsFourth graders = 52 wormsNote how those values add back up to 700, ie 200+140+160+148+52 = 700. This helps confirm the answer.
Then once we see that 52 worms are left, each fourth grader gets 52/13 = 4 worms a piece.
So this is why the final answer is 4.
Help me on Domain and Range
Answer:
Domain: 0 ≤ x < 9
Range: 0 < y ≤ 3
Step-by-step explanation:
The domain is the set of all values used for x-coordinates of all points on the curve.
The range is the set of all values used for y-coordinates of all points on the curve.
Look at the graph. The leftmost point is (0, 3). That point is included in the graph since there is no open circle there.
So far we know this:
Domain goes from 0 to ...
Range goes from 3 to ...
Now we look at the rightmost point. It is (9, 0), but there is an open circle on it, so that point itself is not included in the domain or range.
Now we know this:
Domain goes from 0 to just less than 9.
Range goes from 3 to to just more than 0.
Domain: 0 ≤ x < 9
Range: 0 < y ≤ 3

Hi,
we need to substitute 4 and 1 in the equation, so for every y, we replace it with a 1 and every X with 4 as X= 4, Y = 1
equation: X + X (X + Y) + Y
equation after substituting the numbers: 1 + 1 (1 + 4) + 1
Bidmas rules apply.
expand the bracket first. 1 (1 + 4)=
1 X 1= 1
1 X 4= 4
1 + 4 = 5
then the equation becomes: 1 + 5 + 1= 7
your answer is 7 if you want to evaluate it.
your answer is 1 + 1 (1 + 4) + 1 if you need the equation.
, hope that helps :)
