A triangle has rotation symmetry that can take any of its vertices to any of its other vertices. Select ALL conclusions that we can reach this.
A. All sides of the triangle have the same length
B. All angles of the triangle has the same measure
C. All rotations take one half of the triangle to the other half of the triangle
D, it is a right triangle
E. None of the sides of the triangle have the same length
F. None of the angles of the triangle have the same measure
Answers
Answer:
c e f
Step-by-step explanation:
C. All rotations take one half of the triangle to the other half of the triangle
E. None of the sides of the triangle have the same length
F. None of the angles of the triangle have the same measure
If a shape has a rotation symmetry, then the shape will look exactly the same after rotation. The conclusions to reach for a triangle that has a rotation symmetry are:
A. All sides of the triangle have the same length
B. All angles of the triangle has the same measure
Of all kinds of triangle, only an equilateral triangle has a rotational symmetry.
This means that:
All sides of the triangle must be the sameAll angles of the triangle must be the sameThe complete length of each side are rotated (not half).The above points imply that: options (a) and (b) are true
See attachment for an illustration of rotation symmetry of a triangle.

You need $125 to buy an MP3 player. Your allowance is $5 per week and you earn $20 per lawn mowed
Write an equation that represents your weekly income in dollars for x lawns mowed. Interpret the y intercept . How many lawns do you need to mow to earn enough money in one week to buy the MP3 player?
Answers
Answer:
Answer in explanation
Step-by-step explanation:
The equation of a straight line can be represented in the form;
y = mx + c
where m is slope and c is y-intercept
In this particular case
y = 20x + 5
y is the weekly income, x is the number of lawns mowed
The y-intercept 5 is the amount earned in a week given they no lawn was mowed
In a case where y = 125
125 = 20x + 5
20x = 125-5
20x = 120
x = 120/20
x = 6
You need to mow 6 lawns to earn enough money in one week to buy the MP3 player

Equation of the Quadratic Function
The vertex form of the quadratic function has the following equation:
[tex]y=a(x-h)^2+k[/tex]
Where (h, k) is the vertex of the parabola that results when plotting the function, and a is a coefficient different from zero.
The graph provided in the question, assumed as a parabola, has two clear points:
The vertex, located at (-2,-3)
The point (-1,-6)
Substituting the coordinates of the vertex, the equation of the function is:
[tex]y=a(x-(-2))^2-3[/tex]
[tex]y=a(x+2)^2-3[/tex]
The value of a will be determined by using the other point (-1,-6):
[tex]-6=a(-1+2)^2-3[/tex]
Operating:
[tex]-6=a(1)-3[/tex]
Solving:
a=-3
The equation of the graph is:
[tex]\boxed{y=-3(x+2)^2-3}[/tex]

13(3 - z) = 13(3 - z)
13(3 - z) = 39 - 13z
Step-by-step explanation:
To make the equation have infinitely many solutions, when you simplify, the equation will become z = z
To make this happen, the equation has to be the same on either side of the equal sign. Here are the two options :
13(3 - z) = 13(3 - z)
13(3 - z) = 39 - 13z

If x is direct proportional to y cube and x=32 when y=2
1. Find the value of x when y=6
2. Calculate the value of y when x=108
Answers
Answer:
1x=864,
2y=3
Step-by-step explanation:
y=6,x=?
if x is directly proportional to y^3 &if (when x=32, y is=2) we can understand that x=4y^3
1,x=4y^3
x=4(6^3)
x=4(216)
x=864
2,x=4y^3
108=4y^3
108/4=4y^3/4

√27=y
y=3

Ana is going to a craft fair where she'll sell her handmade scarfs. She has six scarf designs, and she's made 15 of each. She's paid $128 for the booth, and each scarf costs $9.80 to make. How much should she charge for each scarf if she wants to break even after selling a third of her scarves?
Answers
Answer:
$33.6667
Step-by-step explanation:
Given the following :
Number of Scarf designs = 6
Number of each made = 15
Total scarfs = (15 * 6) = 90
Cost:
Booth = $128
Production cost per scarf = $9.80
Total production cost = $9.80 * 90 = $882
Total cost = $128 + $882 = $1010
Break even = profit - loss = 0
One third of scarves = 1/3 * 90 = 30
This means he must cover for the total cost of $1010 after selling 30 scarves
Hence price per scarf will be :
$1010 / 30
= $33.6667

What is the x-intercept of the slope of -2 and a y-intercept of 0, 6
Answers
Answer:
x- intercept = 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 2 and c = 6 , thus
y = - 2x + 6 ← is the equation of the line
To find the x- intercept, let y = 0 in the equation and solve for x
- 2x + 6 = 0 ( subtract 6 from both sides )
- 2x = - 6 ( divide both sides by - 2 )
x = 3 ← x- intercept or (3, 0 )
