We defined the operation of concatenation for sets of strings on p. 10, AB = { XY | X ∈ A and y ∈ B}Are the regular sets closed
lakkis [162]

Answer and Explanation:

Solution: The operation of concatenation for a set of string on p. and the set is

     AB = {XY | X ∈ A and y ∈ B}.

We need to satisfy all these following properties to find out the standard set is closed under concatenation.

1- Union of two standard sets also belongs to the classic collection. For example, A and B are regular. AUB also belongs to a regular group.

2- Compliment of two standards set A and B are A’ and B’ also belonging to the standard set.

3- Intersection of two standards set A and B is A∩B is also a regular set member.

4- The difference between two regular sets is also standard. For example, the difference between A and B is A-B is also a standard set.

The closure of the regular set is also standard, and the concatenation of traditional sets is regular.

Suppose you bought D DVD's and B Books. If each DVD cost $14.95 and each book you bought off the 'specials' table cost $6.95, wr
Doss [256]

Answer:

14.95D + 6.95B

Step-by-step explanation:

Well a simple expression would make D the amount of DVD's you bought and B the amount of Books purchased.

In simple cases the prices don't change depending on that amount so you can multiply them by making it 14.95D and 6.95B.

Making the expression 14.95D + 6.95B.
