Answer:

A.The scale factor is 0.25 ⇒ <u>True</u>

B.The scale factor is 4 ⇒ <u>False</u>

Step-by-step explanation:

<u>See the attached figure.</u>

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.

A dilation that creates a smaller image is called a reduction.

As Shown, two right triangles, The first triangle is dilated to form the second triangle.

We can deduce that the second image is a smaller than the first triangle.

The hypotenuse of the first triangle = 4.4

The hypotenuse of the second triangle = 1.1

So, the scale factor = 1.1/4.4 = 11/44 = 1/4 = 0.25

<u>We will check the options:</u>

A.The scale factor is 0.25 ⇒ True

B.The scale factor is 4 ⇒ False

Someone pls help me plsss
Lelu [443]

Answer:

A) 2 5/12

Step-by-step explanation:

The word <u>MORE </u>refers to subtraction. If you know how to calculate fractions. Great! You should know what 2 3/4 - 1/3 equals. But if you do not:

You can use a regular calculator. Just convert everything to decimals. ( "/" means divide)

3/4 (3÷4) = 0.75 (dont forget the 2 since is has 2 3/4) so 2.75.

1/3 (1÷3) = 0.33<u>3 </u>(underline or overline (above the number) means that number repeats. if you are using a calculator. just max the numbers out till you can put it anymore.

2.75 - 0.<u>3</u> = 2.41<u>6</u>. Now you dont know what that 416 is so just subtract the answers until it matches.

B) 1 ÷ 12 = 0.8<u>3. </u> well it isnt 416 so that isnt right.

4 ÷ 7 = 0.571... (... means a bunch of numbers that go on and on.) again that isnt correct. Now lets try A):

5 ÷ 12 = 0.41<u>6</u>!

Hope this helps!

For which pair of functions is the vertex of k(x)7 units below the vertex of f(x)?
kvv77 [185]

Answer: Option C

f(x) = x^2;\ k (x) = x ^ 2 -7

Step-by-step explanation:

Whenever we have a main function f(x) and we want to transform the graph of f(x) by moving it vertically then we apply the transformation:

k (x) = f (x) + b

If b> 0 then the graph of k(x) will be the graph of f(x) displaced vertically b units down.

If b> 0 then the graph of k(x) will be the graph of f(x) displaced vertically b units upwards.

In this case we have

f (x) = x ^ 2

We know that this function has its vertex in point (0,0).

Then, to move its vertex 7 units down we apply the transformation:

k (x) = f (x) - 7\\\\k (x) = x ^ 2 -7.

Then the function k(x) that will have its vertex 7 units below f(x) is

k (x) = x ^ 2 -7
