linear algebra problem 1. True or False. If true, explain why. If false provide a counterexample. . If A? - B2, then A - B (you can assume that A and B have the same size). • If columns 1 and 3 of B are the same, so are columns 1 and 3 of AB. • If rows 1 and 3 of B are the same, so are rows 1 and 3 of AB. • (AB) - A’B?
Determine whether the statement is true or false. If false, explain why or give a counterexample that shows it is false. (2 pts each) b. If f(x,y) S g(x, y) for all (x, y) in , and both f and g are continuous over 2, then c. If f is continuous over 2 and 22, and if JJ, dA- jJa,dA, then f(x.y) dA- Jf(x.y) dA for any function fx,y). Determine whether the statement is true or false. If false, explain...
6. True or False. If the statement is true, explain why using theorems/tests from class, and if the statement is false provide a counter example. (a) If an and are series with positive terms such that is divergent and an <by for all r, then an is divergent. I (b) If a, and be are series with positive terms such that is convergent and an <br for all 17, then an is convergent. (e) If lim 0+1 = 1 then...
if false, plz do give a data set, thanks 2. Decide if the following is true or false: In every RBD setup, either the MSTR MSE or MSB2 MSE (or maybe both). If it is true, explain why. If it is false, give a data set that is a counterexample. 2. Decide if the following is true or false: In every RBD setup, either the MSTR MSE or MSB2 MSE (or maybe both). If it is true, explain why. If...
True or False: If n=1 an is a series with terms an which are nonnegative real numbers, and the partial sums N=1 an are uniformly bounded in- dependent of N E N, then n=1 An is a convergent series. If true, prove it; if false, give a counterexample.

4. (8 points) True or false? Give a reason if true and a counterexample if false. [ 1] [ 1 3 2007 a) The vector -1 is in the Columnspaceof 0 1 -5 1 0 10 | 2 0 0 3 1 (b) Let A be a 4 x 6 matrix, then the nullspace of A may have only one vector. (c) The product of two rank 1 matrices (assuming the product exists) is also rank 1. Let A be...
any help would be awesome Explain why or why not Determine whether the following state- ments are true and give an explanation or counterexample. a. The sum Σ is a p-series. b. The sumeve IS a p-series. c. Suppose f is a continuous, positive, decreasing function, for re l'and ak =f(k), for k = 1,2,3, . . . . If Σ@g converges to L, then | f(x) dx converges to L. d. Every partial sums, of the series Σ underestimates...
Is the following series cos n convergent or divergent? Prove your result. 2 if Σ an with an > o is convergent, then is Σ a.. always convergent? Either prove it or give a counter example. 3 Is the following series convergent or divergent? if it is divergent, prove your result; if it is convergent, estimate the sum. 4 Is the following series 2n3 +2 nal convergent or divergent? Prove your result.
For each of the statements below, state whether it is true or false. If true, explain why each of its directions → and ← is true. If false state which direction is false and give a counterexample. (a) ∀x (A(x) ∨ B(x)) ↔ ∀xA(x) ∨ ∀xB(x) (b) ∀x (A(x) ∧ B(x)) ↔ ∀xA(x) ∧ ∀xB(x) (c) ∃x (A(x) ∨ B(x)) ↔ ∃xA(x) ∨ ∃xB(x) (d) ∃x (A(x) ∧ B(x)) ↔ ∃xA(x) ∧ ∃xB(x)
