Triangle ABC is located at A(-4, 5), B (-4, -1), and C(-1,1). A translation of the triangle is located at A’(-2, 8), B’(-2, 2), and C’(1, 4). How is the triangle translated?

answer

C. Triangle ABC is translated 2 units right and 3 units up.

Reflection across x axis means (x,y) turns to (x,-y)

just see which 2nd number becomes the oposite of the first one

that is option C

What is the approximate area of a semicircle with a radius of 6 in.? Use π≈3.14 .

### Answers

Area of a circle =πr²

or 3.14r², in your case.

3.14 * 6² = 113.04 in²

A semicircle is half of a full circle, therefore we can just half our answer.

113.04 / 2 = 56.52 in²

I REALLY NEED help someone HELP Triangle XYZ where X(7, 2), Y(-3, 8), and Z(-4, 6) is dilated with a scale factor of two-third Where is the dilation located?

A.X’the coordinate (fourteen-thirds, four-thirds), Y’the coordinate (negative 2, sixteen-thirds)and Z’the coordinate (

B.X’the coordinate (fourteen-thirds, four-thirds), Y’the coordinate (4, negative three-fourths)and Z’the coordinate (two-thirds, negative 2)

C.X’the coordinate (seven-thirds, one-thirds), Y’the coordinate (negative 1, 2)and Z’ the coordinate (negative 1, 1)

D.X’the coordinate (negative one-eighth, negative seven-fourths),Y’the coordinate (negative 2, three-fourths)and Z’ the coordinate (negative 2, three-fourths)

### Answers

The answer is a. the simplest method to ever use in a dilation is multiplying the number by the scale factor. E.g X(7,2), you multiply the x-axis(7) by 2/3= 7* 2/3=14/3. And then multiply the y-axis(2) by 2/3= 2*2/3=4/3. If there are two options that contain the same answer, solve for the next coordinate which is y coordinate. I solved it and got Y( -2,16/3) .this tells me that the answer is A.
