Find a point within a triangle such that the sum of the square of its distances from the three angular points is a minimum.

Expert Solution

Procedure of finding the point:

1. First find out the two variable distance function considering a locus point P(x,y) and adding the squares of distance of point P to each of the vertices.

2. We thendthen the critical points of the distance function by equating fx =0 and fy =0.

3. Then we use the second derivative test on the critical points to find out if the point is a local minimum or local maximum.

We know distance between two points =

Incidentally, this point has a particular name which is known as the centroid of the triangle.

Find the optimal solution for the mini-sum location model assuming: (a) squared Euclidean distances; (b) Euclidean distances. For each case find the optimal location of a new machine, assuming existing machines located at (4, 3), (7, 5), (11, 8), and (13, 4) with weights equal to 1/3, 1/6, 1/3, and 1/6, respectively?.

Consider three point charges at the corners of an equilateral triangle, its base sitting on the x-axis, with charge qA positioned at the origin, qB is at x=+3.50 cm, and qC is at the (top) third corner. qC = +2.60 μC, and the net electric force on qC is 375.0 N in the negative y direction. a. Explain briefly but clearly how you know that qA and qB must have the same magnitude charge and what the sign of that...

Write in c++ as simple as possible In a right triangle, the square of the length on one side is equal to the sum of the squares of the lengths of the other two sides. Write a program that prompts the user to enter the length of three sides of the tringle (as doubles) and the outputs a message indication whether the triangle is a right triangle. You should split this into two functions (but only one .cpp file). One function is main()...

1. Treacherous Triangle Trickery. Consider a charge distribution consisting of an equilateral triangle with a point charge q fixed at each of its vertices. Let d be the distance between the center of the triangle and each vertex, let the triangle’s center be at the origin, and let one of its vertices lie on the x-axis at the point x = −d. 1.1. Compute the electric field at the center of the triangle by explicitly computing the sum of the...
