Consider the following: Claim: For any sets A and B, if for all x A, x 0 and A B, then for all x B, x 0. Proof: Let A and B be arbitrary sets.(2) If the above proof is valid, explain why. Is that how you would have written a proof? Make sure you can explain why these four statements all say the same thing and how each relates to the mod spiral and clock arithmetic. Why is the symbol used instead of an equal sign, ? Examples: Which statements are true and which are not true? What would be the answer to: (x-a)(x-b)(x-c)(x-d)(x-e)(x-y)(x-z)?Are any of them multiples of any of the others? If they are all different, and are not multiples of each other, then we can look for a pattern by starting small and working our way up 1. 1. Once a segment is full a new segment is created within the same heap, so a heap can have many small object heap segments and many large object heap segments but the number of .net heaps will not change during the life of the process.Could you explain why? Thanks, Michal. a) Explain why this is the same as8-0.5547 E-t, -0.

Those dot products are the same x1 and x2 x1 and x3 x2 that we wrote in equation (4). The newC x D 0 has many solutions. 5. This section is looking ahead to key ideas, not fully explained yet.Why is that plane perpendicular to x? 8 Moving to a 4 by 4 difference equation Ax D b, nd the four Note: The above geometrical application also provides a condition that three given vectors, a, b and c lie in the same plane that is, they are coplanar.Consequently, (a x b) x c, which is the same as c x (a x b), will lie in the plane of a and b. Explain why or why not. Use what you learned about simplifying algebraic expressions to complete Exercises 1214 on page 68.Like terms are terms that have the same variables raised to the same exponents. A term without a variable, such as 4, is called a constant. Answer: Explanation. Explain in detailYou can write g(x)abs(x-b)abs(x-d) as a piecewise function in the same way.Why did European countries compete for colonies in Central Africa and East Africa? 15. We have assumed in the notes above that if two polynomials P (x) and Q( x) are equal for all values of x (that is, if their graphs are the same), then their degrees are equal and their corresponding coecients are equal. Here is a proof using calculus. (a) Explain why substituting x 0 proves that Explain why each is discontinuous at x a, and determine the type of discontinuity.550. A particle is moving along the graph of y x. At what point on the curve are the x-coordinate and y-coordinate of the particle changing at the same rate? (15 points.) True or False? Explain why!Answer: The function f is not injective because for instance it maps 1 and 1.5 (and any other point in [1, 2)) to the same number, namely 1. The function f is not surjective because, as we already saw, no element in its range is divisible by 2 and so 4, for instance tHinK a 1 Use the vertical line test to explain why. the graph is of a function. 2 State the type of correspondence.Consider the function f(x) 5x. a Evaluate f(2). b On the same set of axes sketch the graphs of y 5 x, y 5x and y 5x. c Express y 5x in an equivalent form. Product in each case is ABCD so they look the same to me. No clue. Perhaps someone else will know? I can say that the above proof strategy will work for any number of variables in the same form (ABCDEFG why? The data of the problem are b, c, and A. Using the same information, we can write down a new LP.(The next paragraph explains why.) You know how to write the dual of any LP written in the form Section 5.4 p244 Problem 1. In each part, explain why the given vectors do not form a basis for the indicated vector space.(b) One method is to follow the same procedure as for (a).

Can you also explain why adenine does not base-pair with cytosine. and why thymine does not base-pair with guanine? Answer: Hydrogen bonding, which holds the two DNA strands together, determines which nucleotides will form complementary base-pairs. Occasionally, however, Maple needs to be told explicitly that the entries of a matrix are real numbers since the algorithms used for calculating with integers and real numbers often are not the same.5. Calculate the products AB and B A of the matrices A and B in Exercise 3. Explain why AB B A. Yes if both powersets are the same then each set contains the same elements.The Cartesian Product A x B consists of all ordered of the form (a, b) where a is from set A ( math class at ODU) and b is from set B ( math professor at ODU). as the same in P are actually made equal (literally identical) in Q P/ . Our goal is to prove that Q is a realization of the continuum (ie, that it satises the three axioms of a continuum).If X is a rational number, we may choose a representative (a, b) P for X, meaning that [(a, b)] X. Let Y be another 2. Given a surface z f (x, y), and a point P (a, b, c) on that surface, explain why (a) the vector [fx(a, b), fy(a, b)] is perpendicular to the curve f ( x, y) c (b)7. You have seen that equations of the form f (x, y) k dene level curves of function f . In the same way, equations of the form g(x, y, z) k dene In other words, in this case, Cardanos method and Lagranges method compute exactly the same things, up to a factor of three in the auxiliary variables, the main difference being that Lagranges method explains why thesef ( x ) a x 3 b x 2 c x d displaystyle f(x)ax3bx2cxd . ishm, do not answer the same question twice in the archive.
