This is about understanding rigid transformations.

<u><em>Option 4 is not a rigid transformation.</em></u>

  • In mathematics, transformation could be;

Rigid Transformation; This includes reflection, rotation, translation.

Non - Rigid Transformation; This includes dilation and shear.

  • Now, a transformation is said to be a rigid transformation when the newly transformed image retains the same shape and size as it was before it was transformed. Although it can change position.

Whereas, it is termed non - rigid transformation if the shape or size changes.

Let us look at the triangles in the option;

  • Option 1; In this  option, we see that the two triangles maintain the same shape and size and thus the transformation is rigid.

  • Option 2; In this  option, we see that the two triangles maintain the same shape and size and thus the transformation is rigid.

  • Option 3; Similar to options 1 & 2, we see that the two triangles maintain the same shape and size and thus the transformation is rigid.

  • Option 4; We see that one of the triangles is bigger than the other. Since the transformed triangle is not the same size as it was before transformation, then it is not a rigid transformation.

A rectangle has a width of 2cm and a perimeter of 25cm. Find the length and the area .
Gwar [14]

2w + 2l = 25

2 * 2 + 2l = 25

<em><u>Simplfiy.</u></em>

4 + 2l = 25

<em><u>Subtract 4 from both sides.</u></em>

2l = 21

<em><u>Divide both sides by 2.</u></em>

l = 10.5

Now that we have the value of l, we can find the area.

A = lw

A = 10.5 * 2

A = 21.

The length is 10.5cm.

The area of the rectangle is 21cm^2

Please help me Im really about to cryyyy also can some help me with other questions
Hunter-Best [27]

Answer:

x = 25

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse x is equal to the sum of the squares on the other two sides, that is

x² = 20² + 15² = 400 + 225 = 625 ( take the square root of both sides )

x = \sqrt{625} = 25

a home health care assistant prepares 10 and a half ounces of formula the mixture is 1/3 formula and 2/3 water how much formula
Dimas [21]

Total amount of the mixture = 10\frac{1}{2}=10.5 ounces

Proportion of formula = \frac{1}{3}

Proportion of water = \frac{2}{3}

Amount of water needed to make the mixture can be given as:

Total amount of mixture x Proportion of water

Using the values, we get:

Amount of water needed = 10.5*\frac{2}{3} = 7 ounces

Similarly the amount of formula needed will be:

Total amount of mixture x Proportion of formula

Using the values, we get:

Amount of formula needed = 10.5*\frac{1}{3} = 3.5 ounces

Therefore, the home health care assistant needs 3.5 ounces of formula and 7 ounces of water to prepare 10 and a half ounces of formula.
