Rodents & other pests will never get used to the ultrasonic sound waves emitted from this repeller. The Attack Wave effectively protects an area up to 4,000 - 5,000 unobstructed square feet. In a home with rooms, hallways, and furniture the effective range is closer to 2000 square feet.
Definition. of the Centroid of a Triangle. The Centroid is a point of concurrency of the triangle. It is the point where all 3 medians intersect and is often described as the triangle's center of gravity or as the barycent.1  It is formed by the intersection of the medians.he Centroid is a point of concurrency of the triangle.

The centroid coordinates are two thirds away from. the vertex and 1/3 away from the right angle. Consider the right triangle shown in Figure 1. Along the hypotenuse, y = a x. The area of the triangle is The x coordinate of the centroid, X, multiplied by the area is equal to the integral of x multiplied by the area da. That is, it is the sum of the small areas da multiplied by their x coordinate. where, Therefore, Solving for the x coordinate of the centroid,
