Identify the transformation that results in an image that's not congruent to the pre-image. Question 9 options: A) Rotation B) T
Romashka [77]

Answer:

C) Dilation

Step-by-step explanation:

Rotation is simply rotating an object, therefore, the size and shape remain the same.

Translation is moving the object across the plane, and again, the size and shape will stay the same.

Reflection is reflecting a shape across a certain line. It will still keep its size and shape.

However, dilation is enlarging or shrinking a shape. This means that the shape will change size, but not shape. A dilation of a shape will be similar, but not congruent, to it.

Hope this helps :) Feel free to ask me any questions!

Please help me!!!! I have no idea how to do this!!!
Alinara [238K]
Basically, to find consecutive odd interferes, you have to make it so that there's three expressions.

1: x

2: x+2

3: x+4

You plug in those numbers using the equation they gave, then go off from there.

Does the equation y = 23x + 1<br><br> represent a direct variation? Why or why not?
Vlad [161]

Answer:

no

Step-by-step explanation:

The equation of 2 quantities varying directly is

y = kx ← k is the constant of variation

y = 23x + 1 is not in this form so does not represent direct variation.

Given: Z = 0.43Y + 12 ; What is Y when Z = 28
jolli1 [7]
Z = 0.43Y + 12; Z = 28
28 = 0.43Y + 12; insert value of Z
16 = 0.43Y; subtract 12 from both sides
37.21 = Y; divide both sides by 0.43; rounded to nearest hundredth

Fill in the box with the appropriate measure.<br> quick please I have only a few min left
Art [367]

Step-by-step explanation:

first box on the left

r=4

d=8

circumference= 2π*4= 8π

area = π*4*4= 16π

Second box on the left

d=6

r= 3

circumference= 2π*3= 6π

area =π*3*3= 9π

third box on the left

A=36π

A=36πarea= π*r*r

A=36πarea= π*r*rr= 6

A=36πarea= π*r*rr= 6d=12

A=36πarea= π*r*rr= 6d=12circumference= 2π*6= 12 π

the last box

C=18π

C=18πC= 2π*r

C=18πC= 2π*rr= 9

C=18πC= 2π*rr= 9d=18

C=18πC= 2π*rr= 9d=18area= π*9*9= 81π
