Answer:

Reflection is when light bounces off an object. If the surface is smooth and shiny, like glass, water or polished metal, the light will reflect at the same angle as it hit the surface. This is called specular reflection. Light reflects from a smooth surface at the same angle as it hits the surface.

Answer:

Hi, There!

Part A: tell me the Characteristics of a Reflection

There are several important characteristics of a reflection:

A reflection maps a line to a line, a ray to a ray, a segment to a segment, and an angle to an angle. Each piece of the original pre-image is exactly the same in the image.

A reflection preserves lengths of segments. The length of a line segment will be the same in a reflection.

A reflection preserves degrees of angles. The angles of the image are congruent to the angles in the pre-image.

Part B:

Rigid transformation: Moving a figure so that it is in a new location but has the same size, shape, and area. A mathematical reflection is a type of rigid transformation

Part C:

what is Line of reflection: The line over which a pre-image is reflected to create a new image

A square desktop has an area of 324 square inches. What is the length of one side of the desktop

Sveta_85 [38]

Question: The area of a square is 324 square inches. What is the length of one side of the square?
The formula for finding area of squares is:

Length x Width

Squares have 4 sides, and all sides measure the same. If the area is 324 square units, that means the length and width are the same.

x X x=x2

X2=324

x squared(x²) is equal to 324. To find x, you have to do the opposite of squaring, which is finding the square root.

x2= 324 —> square root of 324=x

To find x, you have find the square root of 324.

Square root of 324 is 8

The length of one side is 18 inches
Check:
The formula for finding area is:

Length x Width

The length and width gotten was 18. Put that into the formula:

18 x 18

Multiply:

18 x 18= 324

That means the answer is correct. Your answer is 18 inches.

Answer:

2 : 3

Step-by-step explanation:

Given:

The two cylinders are similar. So, their corresponding dimensions must be in proportion.

$\frac{\textrm{Radius of small cylinder}}{\textrm{Radius of larger cyclinder}}=\frac{12}{18}=\frac{2}{3}=2:3$

$\frac{\textrm{Height of small cylinder}}{\textrm{Height of larger cylinder}}=\frac{20}{30}=\frac{2}{3}=2:3$

Therefore, the similarity ratio of the smaller to the larger similar cylinders is 2 : 3.

9. Which of the following is true about the Venn diagram below?

bonufazy [111]

Answer:

(d) All of the above

Step-by-step explanation:

In order to solve this question we will have to find out which numbers are located in which group (the group of numbers are U, B, B').

So lets start of with finding out what numbers are a part of group U. By looking at that picture we can see that all number on the graph are a part of group U. So.....

U = {0,1,2,3,4,5,6,7,8,9}

Then we can find out what numbers are part of the group B. We just have to include the numbers that are located within the circle and exclude all of the numbers out side of the circle. So........

B = {0,1,4,5,6,7,8}

We find numbers that are parts of group B' by using a similar method that we used to find out what numbers were part of group B (Just this time we include all numbers outside of the circle and exclude all of the numbers inside the circle). So ......

B' = {2,3,9}

Now we see that the right option is option d.
