Can a simple graph exist with 9 vertices all of degree 5?
A simple graph has 6 vertices and 12 edges. Each vertex has degree either 2 or 5. How many vertices have degree 2 and how many have degree 5? Can you draw an example of such graph? Show that in a connected simple graph any two paths of maximum length must intersect (i.e. must have at least one vertex in common).
3 Show that it is not possible to creak a graph with 9 vertices such that the degree ( a of every vertex is 3.
True or False: There exists a simple graph with 9 vertices each of degree 5.
4. Is the graph below bipartite? If so, list the vertices in the one part and the vertices in the second part. As in left = { list of vertices} and right = { list of vertices}
Explain thoroughly!!
2. Let G be a connected (simple) planar graph where the number of vertices = 8. What can be said about the possible number of edges?
Which of these graphs have the property that the removal of any vertex and all edges incident with that vertex produces a planar graph? K7 K5 K4,4 K3,4
Either draw the graph that meets the conditions below or explain why no such graph exists: A 9 vertex connected graph with no loops and no multiple edges with exactly 12 edges and three cycles.
How many edges do the wheel Wn and the complete tripartite graph Kr,s,t have?
