Is this relation a function A. Yes, because every x-value corresponds with a single y-value

B. Yes, because the number of x-values is the same as the number of y-values.

C. Yes, because every x- and y-value is positive.

D. No, because two points with the same y-value have different x- values.

the answer is A. you use the vertical line test

sin3a=12/15

step-by-step explanation:

since one side was multiplied by 3 the other side must also be multiplied by 3.

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.
