Problem 2 - Dominating Set Problem (DSP): A subset D of vertexes in a directed graph G
is a dominating set if every other vertex in G is adjacent to some vertex in D (for every x /2 D there
is an edge (y, x) for some y 2 D). We are asked ”Given an undirected graph G, does it contain a
dominating set of cardinality k?”
Is DSP in P? if not, is it in NP?
• If the problem is in P give a polynomial-time algorithm that decides it;
• If the problem is in NP, but you cannot show that it is in P give a polynomial-time verifier.

Problem 1 - Triangle Problem (TRIANGLE). A triangle in an undirected graph is a
subgraph that has 3 vertexes connected to each other (so that they form a triangle). We are asked
”Given an undirected graph G, does it contain triangle?”
Is TRIANGLE in P? if not, is it in NP?
• If the problem is in P give a polynomial-time algorithm that decides it;
• If the problem is in NP, but you cannot show that it is in P give a polynomial-time verifier.

Does anyone on here know of a good web site to get second grade math sheets for my daughter to get some extra practice??? I have found a couple of sites, but not real pleased with them. I will check any and all that you people give me. She does pretty good at math, just needs extra practice.

According to Yahoo, it's 100. I have 7 percent best answers and 92 percent others!

Okay, I know it's because they've rounded things off, but it still looks silly!

There is this scheme in our townYou buy a certificate containing five names for sh 500. The seller appears last on this list. You are then asked to send another sh 500 to the coordinator of the scheme and sh 1,500 to the person appearing the top of the list. Your total investment comes only shs 2,500. When these monies are paid, you get another five certificates bearing your name at number five on the list. The other people have been moved up one slot each and the person who was at the top removed. Now you sell these papers to five new recruits at sh 500 each. At that point, you recover your sh 2500 , and the numbers begin multiply . When the five certificates with your name at number five are sold, they generate 25 ( 5 x 5) more with you at position four. When these are sold, they produce another 125(25x5) with your name at number three. The next level has 625 (125 x 5) certificates “out there”. Now each of these 3,125 new members will pay you sh 1,500 making at total of sh 4,687,500!
