We know that
and
; to find
we are going to divide
by
:
Since the denoinatorcan't be zero:
We can conclude that the correct answer is
A.
543 multiplied by 543 or (543^2) would equal 294,849
Answer:
The sum of the degrees of all the vertices = 8
Step-by-step explanation:
A tree with 5 vertices. N = 5
The number of edges in any tree with N vertices will be N - 1
Using Euler's Sum of Degrees Theorem: Sum of the degrees of all the vertices equals twice the number of edges.
Hence 2(N-1) ==> 2(5 - 1) ==> 2(4) ==> 8
i can not give the answer unless you still cannot find it after these steps but I have steps that might help
1. Set the matrix (must be square).
2. Reduce this matrix to row echelon form using elementary row operations so that all the elements below diagonal are zero.
3. Multiply the main diagonal elements of the matrix - determinant is calculated.
