For The Dilation With Center (0,0) Shown On The Graph, Your Friend Says The Scale Factor Is . What Is

Answers

Answer 1

Answer:

5/7

Step-by-step explanation:

read the graph

Answer 2

Answer:

Step-by-step explanation:

From the given figure:

Coordinates of Pre-image triangle ABC are:

A (0, 5), B(-5, 0) and C(5, -5)

and

Coordinate of image triangle A'B'C' are;

A'(0, 2), B'(-2, 0) and C'(2, -2)

The rule of dilation with scale factor k and centered at the origin is given by;

(x,y) ---> (kx,ky)

To find k;

A'(0, 2) = A'(0, 5k)

Comparing both sides we get;

5k = 2

k=2/5

Therefore, the correct scale factor is 2/5

He did mistakes in transformations i.e a huge mistake mathematically.

Answers

Answer:

6.32[tex]cm^{2}[/tex]

Step-by-step explanation:

The area of a triangle is the base multiplied by the height, divided by 2. So take the base of 8 cm, then multiply by the height of 1.58 cm, and divide by 2.

[tex]\frac{8*1.58}{2} =6.32 cm^2[/tex]

Answer:

Area = 632mm^2

Step-by-step explanation:

Area of a triangle is

1/2 × base × height

OR

= (base × height)/2

There is a tiny trick tho' because the measurement is given in cm but they asked for the answer in mm. Well, there are 10 millimeters in a centimeter.

So the base given as 8cm is 80mm. And the height given 1.58cm is 15.8mm

Area = 1/2(80)(15.8)

= 40(15.8)

= 632 mm^2

A.
6p = 42
B.
42 + p = 6
C.
6 + p = 42
D.
42p = 6

Answers

The answer is A

It is A because if Quiana had 42 text messages from Yolanda, you will need to find how much text messages does Yolanda have from Pierre. So if you are looking for the answer, you will have to do this:

6p=42
