A triangle has the vertices at A(1,3), B(4,2), and C(3,8). What transformation would produce an image with the vertices A’(3,-1),B’(2,-4), C’(8,-3)? A) Reflection over the x axis

B) Reflection over the line y=x

C) Rotation 90° CW about the origin

D) Rotation 180° about the origin

9514 1404 393

  C) Rotation 90° CW about the origin

Step-by-step explanation:

The transformation for rotation CW 90° is ...

  (x, y) ⇒ (y, -x)

This is apparently the transformation that gets ...

  A(1, 3) ⇒ A'(3, -1)

Attached is a list of the commonly used transformations for your reference.

answer: sorry i can't you.

step-by-step explanation:

the answer is: d) o, f, and kr.

atomic radius of bromine (br) is 114 pm.

atomic radius of oxygen (o) is 73 pm.

atomic radius of fluorine (f) is 72 pm.

atomic radius of krypron (kr) is 112 pm.

the atomic radius of a chemical element is a measure of the size of its atom.

the atomic radius varies with increasing atomic number, but usually increases because of increasing of number of electrons.

the atomic radius decreases across the periods because an increasing number of protons, because greater attraction between the protons and electrons.
