Express each of these quantifications in English. a) ∃x N(x) b) ∀x N(x) c) ˺∃x N(x) d) ∃x ˺N(x) e) ˺∀x N(x) f ) ∀x ˺N(x)Define the following sets: A={x, y, z, t}, B={s, t, u, v, w, x}, C={t, v, u, s}, D={s, t, u, v}Determine whether each of the statements is true, false, or meaningless. State your answer clearly.(You do not have to justify your answers, but they have to be correct.) (a){s, t}⊂D (b)A⊆B (c)A∈C (d)|C|=|B|5 A. Let * be a new logical connective such that p * q does not hold if and only if p and q are either both false or both true. (i) Write down the truth table for p * q (ii) Write down the truth table for (p * p) * (q * q). (iii) Does the table in (b) coincide with a table in *Truth table available on the given image* (By "Coincide" we mean that the respective columns of T and F values are the same) B. Construct a formula in CNF based on each of the following truth tables: *Truth table available on the given image* C. Compute CNF (NNF ( IMPL_FREE ¬(p → ( ¬ (q ∧ ( ¬p → q))))))
- Let l be a line in the x-yplane. If l is a vertical line, its equation is x = a for some real number a. Suppose l is not a vertical line and its slope is m. Then the equation of l is y = mx + b, where b is the y-intercept. If l passes through the point (x₀, y₀), the equation of l can be written as y - y₀ = m(x - x₀). If (x₁, y₁) and (x₂, y₂) are two points in the x-y plane and x₁ ≠ x₂, the slope of line passing through these points is m = (y₂ - y₁)/(x₂ - x₁). Instructions Write a program that prompts the user for two points in the x-y plane. Input should be entered in the following order: Input x₁ Input y₁ Input x₂Part I. Let p, q, and r be the following simple statements: p: Sydney is the capital of Australia. q: Thirteen is a prime number. r: The Trinity University of Asia is in Quezon City. Express each of the following propositions as an English sentence and determine its truth value. Part II. Use the truth table to determine whether the following pairs of statement are logically equivalent or not . 1. ~(p↑q)and~p↑-q 2. p↓(q↑r)and(p↑q)↓(p↑r)5. Suppose X and Y are both TRUE, A and B are both FALSE, P and Q are unknown, which of the following can have the identifiable truth value? a. (P ∨ X) → B s. ( X ∧ Y) → P d. (P→X) ∧ Q f. (A ∨ P) ⇔ X

- 2) (L2) Prove using laws of logic that the conditional proposition (p ∧ q) → r is equivalent to (p ∧ ¬ r) →¬ q. 3) (L3) Show that the converse of a conditional proposition p: q → r is equivalent to the inverse of proposition p using a truth table. 4.1) (L4) Show whether ((p ∧ (p→q)) ↔ ¬p) is a tautology or not. Use a truth table and be specific about which row(s)/column(s) of the truth table justify your answer. 4.2) (L4) Give truth values for the propositional variables that cause the two expressions to have different truth values. For example, given p ∨ q and p ⊕ q, the correct answer would be p = q = T, because when p and q are both true, p ∨ q is true but p ⊕ q is false. Note that there may be more than one correct answer. r ∧ (p ∨ q) (r ∧ p) ∨ qI.
