Prove AnB subset A subset AUB?
I shall answer this under the assumption that 'n' means intersection. Recall the definitions of intersection and union: 1) x is an element of AnB if and only if x is an element of A and x is an element of B 2) x is an element of AUB if and only if x is an element of A or x is an element of B and recall that 3) X is an (improper) subset of Y if and only if every element of X is an element of Y Thus, if x is an element of AnB, then x is an element of A and an element of B, so it clearly is an element A (law of simplification in logic). This implies AnB is a subset of A. Now if x is an element of A, it is certainly an element of A or an element of B (law of addition in logic), and therefore x is an element of AUB. There are other ways of answering this based on axiomatic approaches.

Asked in Algebra
What is a relation in which each element of the first set is paired with exactly one element of the second set?
If every element of the first set is paired with exactly one element of the second set, it is called an injective (or one-to-one) function. An example of such a relation is below. Let f(x) and x be the set R (the set of all real numbers) f(x)= x3, clearly this maps every element of the first set, x, to one and only one element of the second set, f(x), even though every element of the second set is not mapped to.
Heavy radioactive elements decay to form what element?
Heavy radioactive elements (parent nuclei) decay to form daughter products that are as varied in number as the parents. Each heavy element has its own daughter. To find the decay mode and end products of the radioactive decay for a given isotope, use a Table of Nuclides. A link is provided to the interactive chart posted by the National Nuclear Data Center at the Brookhaven National Laboratory. The final stable element formed by all radioactive decay is lead (element number 82).

Asked in Chemistry
How does the discovery of isotopes contradict Dalton's theory?
One of the tenets of Dalton's atomic theory was that atoms of an element are all identical to each other. However, isotopes are "versions" of an element that have different numbers of neutrons, so this clearly doesn't fit into his theory. Of course, when he proposed this theory, he didn't know about isotopes yet.
Asked in Sales and Customer Service
What are three important elements of customer service?
One important element of customer service is to smile and put the customer at ease. Another element and maybe the most important is to always put the customer first. Do not make it seem like an effort or hassle to help them, however unusual the request. Another key element is good communication. Speak clearly and slowly so the customer understands exactly what is being said.
Asked in Letters Notes and Memos, Business Writing
Should most business letters have justified alignment?
There are no strict rules for indenting or justified alignment for business letters. The important element of formatting is to ensure that the necessary standard parts of a business letter are included and that they follow a logical sequence. The important element is that the recipient can clearly follow and understand the information provided by a business letter.
