Prove that p (gp) is a tautology using the laws of propositional logic.
Prove that p((pVq) → q) is a tautology using the laws of propositional logic.
Let us say a natural number n is ok if there are two natural numbers whose sum
is n and whose product is n. (Convention: the natural numbers consist of 0, 1, 2,...)
(a) Give a logical expression that means "n is ok".
(b) Show that 0 and 4 are both ok.
(c) Give a logical expression that means "every natural number is ok".
(d) Give a logical expression that means "it is not the case that every number is ok". Push
the negations into the expression as far as possible.

Let E(x, y) be a two-variable predicate meaning "x likes to eat y", where the
domain of x is people and the domain of y is foods. Write logical expressions that represent
the following English propositions:
(a) Alice doesn't like to eat pizza.
(b) Everybody likes to eat at least one food.
(c) Every student likes to eat at least one food other than pizza.
(d) Everyone other than Alice likes to eat at least two different foods.
(e) There are two different people that like to eat the same food.
Show all steps. Correct answer is 1/2sec(theta) +Ccos(theta)

- Ruff, Inc. makes dog food out of chicken and grain. Chicken has 10 grams of protein and 5 grams of fat per ounce, and grain has 2 grams of protein and 2 grams of fat per ounce. A bag of dog food must contain at least 222 grams of protein and at least 162 grams of fat. If chicken costs 11¢ per ounce and grain costs 1¢ per ounce, how many ounces of each should Ruff use in each bag of dog food to minimize cost?

Remember that: A matrix is in row echelon form if Any row that consists only of zeros is at the bottom of the matrix. The first non-zero entry in each other row is 1. This entry is called aleading 1. The leading 1 of each row, after the first row, lies to the right of the leading 1 of the previous row.arrow_forward7. Show that for R sufficiently large, the polynomial P(z) in Example 3, Sec. 5, satisfies the inequality |P(z)| R.
