 Hi, and welcome to our session. Let us discuss the holy question. The question says, find the Cartesian equation of this pair, which is points A having coordinates 2 minus 3 4, and B having coordinates minus 5, 6, minus 7, as the endpoints of one of its time meter. Also find its center and radius. Now we begin with the solution. A, B is the diameter of this pair. Coordinates of endpoints of time meter is given to us, and we have to find the Cartesian equation of this pair. And we have to also find center and radius of this pair. Now let C be the center of the sphere of A, B. We easily find that point of A, B by using the section formula. Right? Generates of C will be A divided by 2 and A divided by A, B. You can find A, B by using distance formula 121, and take care.
