Identify the set as integers, natural numbers, or whole numbers. -1, 0, 1, 2, 3

In set theory, the complement of a set A refers to elements not in A. The relative complement of A with respect to a set B, written B \ A, is the set of elements in B but not in A. When all sets under consideration are considered to be subsets of a given set U, the absolute complement of A is the set of elements in U but not in A.

The empty set is the set containing no elements. In mathematics, and more specifically set theory, the empty set is the unique set having no elements; its size or cardinality (count of elements in a set) is zero.

Roster Form: This method is also known as tabular method. In this method, a set is represented by listing all the elements of the set, the elements being separated by commas and are enclosed within flower brackets { }. Example: A is a set of natural numbers which are less than 6.

Set-Builder Notation. A shorthand used to write sets, often sets with an infinite number of elements. Note: The set {x : x > 0} is read aloud, "the set of all x such that x is greater than 0." It is read aloud exactly the same way when the colon : is replaced by the vertical line.

Universal set:the set containing all objects or elements and of which all other sets are subsets.

HARDEST QUESTION IN THE ENTIRE WORLD. CAN YOU SOLVE?

makvit [3.9K]

Hello, there!

The distance from Mia to Eva is 15 feet, and the distance from Mia to Abigail is 25 feet. A triangle is drawn connecting the positions of Mia, Abigail, and Eva. How far is Eva from Abigail if the angle marking Mia’s position is 50°?

Let's pretend that:

Mia is point A

Abigail is point B

Eva is point C.

The answer is 19.2 feet.

That means that the answer is C

I have drawn the triangle to scale, and attached it below. That way, you can see how I got this answer.

I hope I helped!

Let me know if you need anything else!
