Answer:

Step-by-step explanation:
Given : Vertices of Triangle
,
and 
To find : Centroid of a triangle
The centroid of a triangle is the point of intersection of the three medians of the triangle.
The formula to calculate the centroid of a triangle is:

Where,
are the coordinates of the centroid
Substituting the values in the formula gives us:



Therefore, 
Answer:
D
Step-by-step explanation:
the polynomial written in descending order:
3X^10+X^6+2X^2-4X+8
Answer: 2/3 (two thirds)
Explanation: Divide both denominator and numerator by the common factor of fourteen
This is equivalent to:
(2.2533/2.59)(10^8/10^4)
(0.87)(10^4) which is:
0.87X10^4 which is equal to:
0.87X10000 which is equal to:
8.7X1000 and since 1000=10^3 we can say:
8.7X10^3
