Which rule is an example of rigid transformation?

Mathematics
1 answer:
GalinKa [24]3 years ago

We know that

Rigid transformation:

A rigid transformation (also called an isometry) is a transformation of the plane that preserves length.

Reflections, translations, rotations, and combinations of these three transformations are "rigid transformations"

so, it's length must be preserved

now, we will check each option

option-A:

we have (x,3y)

y-value changes but x-value will remain same

It changes length

so, this is not rigid transformation

option-B:

we have (3x,y)

x-value changes but y-value will remain same

It changes length

so, this is not rigid transformation

option-C:

(2x, y+2)

It changes length of x-value

but it is only shifting y-value

so, it changes length

so, this is not rigid transformation

option-D:

Both shifts values

but it's length will always be same

so, this is rigid transformation..............Answer

How do u find the area?
nydimaria [60]
Act like it's a rectangle. The height is 10 because 7+3=10 and the length it 27. Multiply them for the are and you get 270 in. Then multiply 6x7=42 because that's the are of the space that is missing from the imaginary rectangle. Multiply by 2 (84 in.) because there are 2 missing spaces and subtract from 270= 186 inches is your answer.

When the following expression is written in simplest form, what is the coefficient of the variable term? -2.5y + 8y - 10.5y
LUCKY_DIMON [66]

Answer:

Option 1 is correct.

-5

Step-by-step explanation:

Given:

The given expression is.

=-2.5y+8y-10.5y

Write the given expression in simplest form.

=-2.5y+8y-10.5y

Add negative term of y.

=-13y+8y

=-5y

The simplest form of given expression is =-5y

Therefore, the coefficient of the variable term is -5

A store buys frozen burritos from a supplier for $1.40 each. The store adds a markup of 80% to determine the retail price. This
boyakko [2]
$1.40  -  price from a supplier = 100%
100% + 80% = 180% = 1,8  -  the retail price

1,40 * 1,8 = $2,52 - the retail price 

100% - 25% = 75% = 0,75  -  on sale for 25% off 

2,52 * 0,75 = $1,89  -   the sale price.
