Question:
Miriam is making a bulletin board that is shaped like a square. She has 72 inches of border material. If x represents the length of one side of the bulletin board, which inequality model and solution set best represents the possible side lengths of Miriam's bulletin board?
Answer:
Step-by-step explanation:
Given
Required
Determine an inequality for x
Represent the side lengths of the border with y. So:
Since the border is on the 4 sides, then
-- i.e. the perimeter of the border material
Solve for y
Recall that x represents the board's side length.
Since x will be situated inside the boarder, then.
Substitute
Answer:
The value of a Cartesian product between an empty set and set A is equal to the empty set.
Step-by-step explanation:
The cartesian product is given by:
A×B= {(a,b): a∈A, b∈B}
This means that each element of set A is combined with an element of set B.
The empty set is the unique set having no elements and its size is zero.
Let Ф be the empty set and let A be a set of elements chosen from U.
A×Ф=Ф
Since the empty set has no elements, no ordered pairs can be formed and the result is the empty set.
The answer would be z=wx/6
