Suppose that x is a tree such that for every vertex v of x, (deg(v))%3=1. Prove that x cannot have 25 vertices.
Can you draw the tree diagram for this please 12. Let T be a tree with 8 edges that has exactl 5 vertices of degree 1Prove that if v is a vertex of maximum degree in T, then 3 < deg(v) < 5 12. Let T be a tree with 8 edges that has exactl 5 vertices of degree 1Prove that if v is a vertex of maximum degree in T, then 3
Please write your answer clearly and easy to read. Please only answer the ones you can. I will upvote all the submitted answers. Question 5. Prove by contradiction that every circuit of length at least 3 contains a cycle Question 6. Prove or disprove: There exists a connected graph of order 6 in which the distance between any two vertices is even Question 7. Prove formally: If a graph G has the property that every edge in G joins a...
1. Suppose the address of vertex v in the ordered rooted tree T is 4.5.4.6. At what level is v? What is the address of the parent of v? What is the least number of siblings v can have? What is the smallest possible number of vertices in T? If v has two children, what are their addresses? 2. Suppose the address of vertex v in the ordered rooted tree T is 4.3.5.3.4. At what level is v? What is...
Suppose that T is a tree with four vertices of degree 3, six vertices of degree 4, one vertex of degree 5, and 8 vertices of degree 6. No other vertices of T have degree 3 or more. How many leaf vertices does T have?
Answer all the BLANKS from A to N please. 7. For the graph shown below at the bottom, answer the following questions a) Is the graph directed or undirected? b) What is the deg ()? c) Is the graph connected or unconnected? If it is not connected, give an example of why not d) ls the graph below an example of a wheel? e) Any multiple edges? 0 What is the deg'(E)? ) What is the deg (B)? h) Is...
Discrete Structures 3. Suppose that the address of the vertex v in the ordered rooted tree T is 3.4.5.2.4 At what level is v? What is the address of the parent of v? What can you conclude about the number of siblings v? What is the smallest possible number of vertices in T? List the other addresses that must occur 3.

Discrete Math: Please help with all parts of question 5. I have included problem 3 to help answer part (a) but I only need help with question 5! 5. 3. (a) (4 points) Prove that a graph is bipartite if and only if there is a 2-coloring (see problem 3) of its vertices. (b) (4 points) Prove that if a graph is a tree with at least two vertices, then there is a 2-coloring of its vertices. (Hint: Here are...
Solve all parts please 5. In the following problems, recall that the adjacency matrix (or incidence matrix) for a simple graph with n vertices is an n x n matrix with entries that are all 0 or 1. The entries on the diagonal are all 0, and the entry in the ih row and jth column is 1 if there is an edge between vertex i and vertex j and is 0 if there is not an edge between vertex...
Answer the following true or false questions with a brief justification. A) There exists an undirected graph on 6 vertices whose degrees are 4, 5, 8, 9, 3, 6. B) Every undirected graph with n vertices and n − 1 edges is a tree. C) Let G be an undirected graph. Suppose u and v are the only vertices of odd degree in G. Then G contains a u-v path.
