Answer:

4 feet

Step-by-step explanation:

Let the side length of the square be x feet.

x^2 - 5 = 59

x^2 = 64

x = ±4 (reject - 4 since length > 0)

Let S(x, y) denote the statement "x has seen y" and D denote the set of all students in our class and M be the set of all movies
oksano4ka [1.4K]

Answer:

Step-by-step explanation:

a) Recall the quantifiers \forall, \exists.

Then, we can translate the proposition as follows

\forall m \in M \exists x \in D \exists y \in D S(x,m)\land S(y,m)

b) Recall that an expression of the form \exists x P(x) its negation is of the form \forall x \neg P(x) which means that it is not true that for all elements the proposition P holds. Equivalently, we have that the negation of an expression of the form \forall x P(x) is \exists x \neg P(x) which means that there is at least one x such that P doesn't hold. Using this, we get the following

\neg(\forall m \in M \exists x \in D \exists y \in D S(x,m)\land S(y,m))= \exists m \in M \neg (\exists x \in D \exists y \in D S(x,m)\land S(y,m))= \exists m \in M \forall x \in D \neg (\exists y \in D S(x,m)\land S(y,m))= \exists m \in M \forall x \in D \forall y \in D \neg(S(x,m)\land S(y,m))

By De Morgan's law, we have that \neg (A \land B) = \neg A \lor \neg B

So, the final statement is

\exists m \in M \forall x \in D \forall y \in D \neg S(x,m) \lor \neg S(y,m)

c)

This statement means: There is a movie that for every pair of students, at least one of the students hasn't seen the movie yet.

PLS ANSWER QUESTION. PLS ASAP. AND YOU WILL SAVE ME.
Maksim231197 [3]

Answer:

less than, more than, more than, more than (in order)

Step-by-step explanation:

It depends on the number you're multiplying to 6 3/4.

For example, for the first one, the equation is 6 3/4 x 1/2.

Since 1/2 is less than 1, the answer will be less than 6 3/4.

The zero of the polynomial f(x) = -2x +8​
Damm [24]

Answer:

x = 4

Step-by-step explanation:

to find the zero let f(x) = 0 , that is

- 2x + 8 = 0 ( subtract 8 from both sides )

- 2x = - 8 ( divide both sides by - 2 )

x = 4
