Apply the pythagorean theorem to find the distance between points a and b. a) 32 units b) 34 units c) 64 units d) 68 units

Distance between points A and B is, units

Step-by-step explanation:

Given the coordinates point :

A = (4 , 2) , B = (-4, 0) and C = (4, 0)

Using distance formula:

i,e

First calculate the length of AC ;

where A = (4, 2) and C = (4, 0)

then using distance formula;

= 2 units.

Similarly, calculate the length of BC;

Using distance formula on the given points B =(-4, 0) and C = (4, 0)

then;

= 8 units.

Now, using Pythagorean theorem in triangle ACB; to find the distance AB

Substitute the values of AC = 2 units and BC = 8 units;

Simplify:

or

units.

Therefore, the distance between points A and B is, units

answer for #1 is c

answer for #2 is d

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.
