Let A and B be two sets. For each of the following equalities, say whether the quality is always true, never true, or sometimes
lions [1.4K]

Answer:

hello your question is incomplete below is the missing parts

(a) A\ (A\B) = B\(B\A)

(b) A\ (BA) = B\(A\B)

answer : A\ (A\B) = B\(B\A) = always true

               A\ (BA) = B\(A\B) = sometimes true and sometimes false

Step-by-step explanation:

(a) A\ (A\B) = B\(B\A). = ALWAYS TRUE

using de Morgan's law to prove this

A\ (A\B) = A\ ( A ∩ B^c )

             = A ∩ ( A^C ∪ B )

             = ( A ∩ A^C ) ∪ ( A ∩ B )

             = Ф ∪ ( A ∩ B )

             = ( A ∩ B )

ALSO : B\(B\A) = attached below is the remaining parts of the solution

B) A\ (BA) = B\(A\B) = Sometimes true and sometimes false

attached below is the prove using De Morgan's law

Amy looks up to the 8-foot basketball hoop as shown. If the vertical distance from the ground to Amy’s eyes is 5.9 feet, what is
Igoryamba
The angle of elevation<span> of an object as seen by an observer is the </span>angle<span> between the horizontal and the line from the object to the observer's eye (the line of sight). since you did give the horizontal distance between amy and the hoop, so let us represent it as x.
so the angle of elevation = tan^-1 ( (8 - 5.9) / x)
angle elevation = tan^-1 ( 2.1 / x )</span>
