Hi there!

There are four different types of transformations:

-Reflections

-Translations

-Rotations

-Dilations

In a reflection, the shape is simply reflected across a line of reflection. It does not change size or shape, so therefore it is a congruence transformation.

In a translation, the shape is moved up, down, left, or right. It does not change size or shape, so therefore it is a congruence transformation.

In a rotation, the shape is rotated around a point of rotation. It does not change size or shape, so therefore it is a congruence transformation.

In a dilation, the shape is made larger or smaller by a scale factor. It does change size, so therefore it is not a congruence transformation.

The transformation that is not a congruence transformation is a DILATION.

Hope this helps!! :)

If there's anything else that I can help you with, please let me know!

I'm sorry but maybe you wrote this wrong. If Wendy has 1 pint of milk and only needs 1 pint of milk, then she has exactly the amount she needs.

Liam explains that drawing a yellow card is equivalent to drawing a blue card followed by a red card how many spaces forward or

Ivenika [448]

Complete question :

designs a board game in which a card is drawn on each turn. • A blue card means move forward 4 squares. • A red card means move back 6 squares. Liam suggests adding some other cards to Sia's game Part A Liam explains that drawing a yellow card is equivalent to drawing a blue card followed by a red card. How many spaces forward or backward does a player move after drawing a yellow card? Justify your answer.

Answer:

2 squares backward

Step-by-step explanation:

Given the rule :

Blue card = 4 squares forward

Red card = 6 squares backward

Yellow card = drawing a blue followed by a red

Spaces moved after drawing a yellow card:

Yellow equals :

Blue = + 4 squares ; then

Red = - 6 squares

Net total movement :

Blue + red

+4 + (-6)

4 - 6

- 2

2 squares backward

Find the 53rd term of the arithmetic sequence<br> 27,11, -5

vivado [14]

Answer:

The 53rd term of this arithmetic sequence is -805.

Step-by-step explanation:

The general rule of an arithmetic sequence is the following:

$a_{n+1} = a_{n} + d$

In which d is the common diference between each term, that is, $d = a_{3} - a_{2} = a_{2} - a_{1}$ .

To find the nth term of the sequence, this equation can be written as:

$a_{n} = a_{1} + (n-1)d$

27,11, -5

So $a_{1} = 27, a_{2} - a_{1} = 11 - 27 = -16[/tex[tex]a_{n} = a_{1} + (n-1)d$

$a_{53} = a_{1} + (52)d = 27 + 52*(-16) = -805$

The 53rd term of this arithmetic sequence is -805.
