2. Let A={1,2,3,4,...,45} and R be the relation defined as “is square of” on A. Write R as a subset of AX A. Also, find the domain and range of R.
A Relation is giyen by the set {(2,y)/y=x +3, € 0,1,2,3,4,5}}. Determine its
3

22 and 22

step-by-step explanation:

10 plus 12 equals 22.

12 plus 10 also equals 22 because regardless of what order they're in, they're gonna equal the same thing.

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.

r = 78539458390583095803458309458039485093485 or just 3
