Web[12 marks] Prove the following theorems using strong induction: a. [6 marks] Let us revisit the sushi-eating contest from Question 13. To reiterate, you and a friend take alternate turns eating sushi from a shared plate containing n pieces of sushi. On each player's turn, the current player may choose to eat exactly one piece of sushi, or ⌈ 2 n ⌉ pieces of sushi. WebProof: Let a;b;c 2Z. Assume that ajb and bjc. Then b = ak for some k 2Z and c= bqfor some q2Z. Thus c= bq= akq. Since kq2Z, ajc. 22. Find the largest integer that cannot be created from a (nonnegative) number of stamps of size 4 and 7. Then prove that all larger numbers can be so represented, by strong induction. The largest integer in 17.

Web1. (2 Points) Show by strong induction (see HW5) that for every n∈N, there exists k∈Z such that k≥0 and 2k∣n and 2kn is odd. 2. Consider the function f:N×N (x,y) 2x−1 (2y−1).N (a) (1 Point) Show that it is surjective. (b) (2 Points) Show that it is injective. Show transcribed image text Expert Answer Transcribed image text: Problem 2. 1. WebIf k+ 1 is odd, then k is even, so 2° was not part of the sum for k. Use strong induction to show that every positive integer n can be written as a sum of distinct powers of two, that is, as a sum of a subset of the integers 20 = 1, 21 = 2, 22 = 4, and so on. Let P (n) be the proposition that the positive integer n can be written as a sum of ... function of the flagella in a cell
Let Sn = the sum of the first n odd numbers greater than 0
WebThen we must have n − 2h < 2h + 1 − 2h 2h(2 − 1) 2h. Hence the greatest power, say 2g, of 2 such that 2g ≤ n − 2h must satisfy g < h. By strong induction on h we can assume that n − … WebPerson as author : Pontier, L. In : Methodology of plant eco-physiology: proceedings of the Montpellier Symposium, p. 77-82, illus.
