3. On a coordinate plane, a line segment has P(6,2) and Q(3,8).

Point M lies on PQ and divides the segment so that the ratio

of PM:MQ is 3:2. What are the coordinates of point M?

A. (4.5, 5.0)

B. (5.6, 4.2)

C. (4.8, 4.4)

D. (4.2, 5.6)

Step-by-step explanation:

Given

Required

Determine the coordinates of M

To solve this, we make use of the following partition formula:

Substitute values for m, n, x's and y's

Option D is correct

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5

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.
