Answer:

6 segments are required to connect each point to every other point.

Step-by-step explanation:

If four points are placed on a circle.Then as we know the segment is a line that join two points.

Now as we are given four points on the circle.

  • so we will firstly start with the first point; the first point requires 3 segments to connect to the remaining three points.
  • Next second point will just require 2 segments to connect to the two points as it is already connected to the first point.
  • similarly third point requires just one segment to connect to the last point as it is already connected to first and second point as done above.
  • and hence by the above three steps the fourth point is connected to all the points.

Hence, 6 segments are required to connect each point to every other point.

AleksandrR [38]

Answer:

U₂₁ and U₂₂ fits in the line of upper triangular

Step-by-step explanation:

As explain in the question

An upper triangular matric is square matrix with all zeros below its daignal. A lower triangular matrix is a square matrix with all zeros above its diagonal.

(as shown in the attached image)

(a)for all 3×3 upper triangular matirices U, verify that U2 is also upper triangular

for a matrices U (having a 3*3 matrix), assuming for example, U is given below:

U = \left[\begin{array}{ccc}1&2&3\\0&5&6\\0&0&9\end{array}\right]

the element in the upper triangular are 1,2,3,5,6,9 (U₁₁, U₁₂, U₁₃; , U₂₂, U₂₃, U₂₂)

while lower triangular are 0,0,0, the element in the lower triangular are (U₂₁, U₃₁,U₃₂)

U₂₁ and U₂₂ fits in the line of upper triangular
