Let A = {2, 3, . . . , 50}, that is, A is the set of positive
integers greater than 1 and less than 51. Determine the smallest
number x such that every subset of A having x elements contains at
least two integers that have a common divisor greater than 1, and
justify your answer.

Determine if the given set is a subspace of P4. Justify your answer. All polynomials of degree at most 4, with integers as coefficients. Complete each statement below. The zero vector of P4 in the set because zero an integer The set v closed under vector addition because the sum of two integers an integer The set closed under multiplication by scalars because the product of a scalar and an integer an integer Is the set a subspace of P4?...
Let R be the relation on the set of ordered pairs of positive integers such that ((a, b), (c, d)) Element R if and only if ad = bc. Show that R is an equivalence relation What is the equivalence class of of (1, 2), i.e. [(1, 2)]?

1.) Prove the following theorem
Theorem 3.4.6. A set E C R is connected if and only if, for all nonempty disjoint sets A and B satisfying E AU B, there always erists a convergent sequence (xn) → x with (en) contained in one of A or B, and x an element of the other. (2) (10 points) Are the following claims true or false? You must use the ε-δ definition to justify your answers. x-+4 r2 16 (Here [[x]-greatest...
(a) In the vector space, V = {f : R → R}, prove that the set {x9,sin5x,cos2x} is linearly independent. (b) Is {(1,2,3),(−2,1,0),(1,0,1)} a basis for R3? Justify your answer.
1. Which complete bipartite graphs Km,n, where m and n are positive integers, are trees? Justify your answer 2. How many edges does a tree with 229 vertices have? Justify your answer.
Consider the system of components connected as in the
accompanying picture. Components 1 and 2 are connected in parallel,
so that subsystem works if and only if either 1 or 2 works; since 3
and 4 are connected in series, that subsystem works if and only if
both 3 and 4 work. If components work independently of one another
and P(component i works) = 0.73 for
i = 1, 2
and = 0.65 for
i = 3, 4,
calculate P(system...
6.2.24 Justify each Assume all vectors are in R. Mark each statement True or False. Justify each answer a. Not every orthogonal set in Rn is linearly independent. O A. False. Orthogonal sets must be linearly independent in order to be orthogonal. O B. True. Every orthogonal set of nonzero vectors is linearly independent, but not every orthogonal set is linearly independent. O C. False. Every orthogonal set of nonzero vectors is linearly independent and zero vectors cannot exist in...
