The two numbers that differ by 46 is 23
Use SOHCAHTOA. sin=opposite/hypotenuse, cosine=adjacent/hypotenuse, and tangent=opposite/adjacent
This is impossible to answer without knowing what the sets A and B contain (and what ξ even refers to - universal set?).
However, we have
(A U B)' = A' ∩ B'
so that
(A ∩ B) U (A U B)' = (A ∩ B) U (A' ∩ B') = (A U A') ∩ (B U B')
If ξ is indeed the universal set, then both A U A' = ξ and B U B' = ξ, so we end up with ξ ∩ ξ = ξ.
Answer:
Between 3 and 4
Step-by-step explanation:
3^2 = 3 × 3 = 9
4^2 = 4 × 4 = 16
12 is between 9 and 16
