Proof by contradiction that the product of any nonzero rational number and any irrational number is irrational (Must use the method of contradiction). Which of the following options shows an accurate start of the proof. Proof. Let X+0 and y be two real numbers such that their product xy=- is a rational number where c, d are integers with d 0. Proof. Let x0 and y be two real numbers such that their product xy is an irrational number (that...

Claim: {(-1)"} does not converge to any real number a. Proof: Assume that the sequence converges; that is, assume that there is an a E R such that lim,--.(-1)" = a. Then, using E = 1, from the definition of convergence, we know that there exists an no such that |(-1)" - al < 1 for all n > no. Thus, for any odd integer nno, we have |(-1)" - al = 1-1-a[< 1, and for any even integer n>...

7. Give a proof by contradiction that for any subset S of 26 cards from a 52 card deck ( a 52 card deck is composed of 4 suits of 13 cards each), there is a suit such that S has at least 7 cards of that suit. This is an application of the pigeonhole principle.

DO NOT USE CP, IP, or AP in your proofs. I will
not accept any proofs using CP, IP, or AP. Additionally, use only
the 18 rules of inference found in the text and in the notes. If
you use an inference rule such as Resolution or
