Below is the linear programming for the Shortest Path Problem. Considering the second contraint in the mathematical model :
∑ixji−∑ixij=0∀j≠s, j≠t
What is the logic behind this contraint?
A. To make sure there is only one solution
B. To make sure that the path is connected between the nodes
C. To make sure the variable stays binary
D. This contraint is redundant and not necessary

it would take 7/10 of an hour too fill the pool.

step-by-step explanation:

hi how are you doing today, if you need just ask me.

step-by-step explanation:

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
