Unit test: line and triangle relationships - part 1 question 8

What are the coordinates of the centroid of a triangle with vertices P(−4, −1), Q(2, 2), and R(2, −3)?

Enter your answers in the boxes.

( , )

Step-by-step explanation:

Given that:

The coordinates of the vertices of a triangle are given as:

, , and .

To find:

The coordinates of the centroid of the triangle.

Solution:

The coordinates of the centroid of a triangle is given as:

Where are the coordinates of the vertices of the triangle.

As per the given values, we have:

Putting the values,we can find the coordinates of centroid as:

Therefore, the coordinates of the centroid is:

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.
