Starting from the four numbered premises below (which using only the rules of inference (including the instantiation and generalization rules) and the logical equivalences (as both were Make sure that you include both the rule and the line number(s) to which that rule is applied are assumed to be true) and presented in class), show that x E(x) (6 marks) 1) Vx A(x) AGB(x) 2) Эx С (x) — В (х) 3) Vx D(x) > с (х) 4) x...

This is for a computer database class, thank you! Prove or disprove the following inference rules for functional dependencies. A proof can be made either by a proof argument or by using inference rules IR1 through IR3. A disproof should be done by demonstrating a relation instance that satisfies the conditions and functional dependencies in the left hand side of the inference rule but do not satisfy the conditions or dependencies in the right hand side. {W rightarrow Y, X...
1. Py --> [ (Qy ● Ry) v Sy ] 2. (Qy ● Ry) ---> ~ Py 3. Ty ---> ~ Sy // (Py --> ~Ty) Prove valid using the 18 rules of inference.
How to do this problem for discrete math. Use the rules of inference to show that if V x (Ax) v α刈and V xứcAx) Λ α where the domains of all quantifiers are the same. Construct your argument by rearranging the following building blocks. ) → Rx)) are true, then V x("A(x) → A is also tr 1. We will show that if the premises are true, then (1A(a) → Pla) for every a. 2. Suppose -R(a) is true for...
Discrete Structures, Rules of Inference Questions 1) Prove that the premises "There is someone in this class who has been to France" and "Everyone who goes to France visits Louvre" imply the conclusion "Someone in this class has visited Louvre".
-Use the rules of inference and the laws of propositional logic to prove that each argument is valid. Number each line of your argument and label each line of your proof "Hypothesis" or with the name of the rule of inference used at that line. If a rule of inference is used, then include the numbers of the previous lines to which the rule is applied. For the arguments stated in English, transform them into propositional logic first. a) (10...
5. Let ū and w be vectors in R3. Prove that (ö - w) x (v + 2) = 2(vx w).
I just need help with detailed explanations for b and c Use the rules of inference and the laws of propositional logic to prove that each argument is valid. Number each line of your argument and label each line of your proof "Hypothesis" or with the name of the rule of inference used at that line. If a rule of inference is used, then include the numbers of the previous lines to which the rule is applied. (a) p q...
