The answer would be: 3hours 8mins 10 sec
Out of the choices given, B and E will be opposite of each other when the folding occurs. You have to imagine what it would look like, once folded.
-28+28=0, and you add 38. 38 degrees.
A=128x^3*pi +128x^2*pi +40*pi x+4*pi
no spaces is this kind of complicted?
Using Union function of set theory, we get the answer as
A∪B= {3,4,6,8,9,12,15,16,20,21}.
What is Union function?
- The set containing all the elements in a collection of sets is referred to as the union (denoted by ) in set theory. This was one of the core elements that allows sets to be joined together and connected to one another.
- A union of zero A∪B sets is referred to as a nullary union, which is by definition equivalent to the empty set.
- The set containing items in A, B, or both A and B is the union of the two sets A and B.
- In set-builder notation, "displaystyle A" means "∪" and "B" means "x"
- A∪B equals x: x in A's text or x in B's.
Using Union function of set theory, we get the answer as
A∪B= {3,4,6,8,9,12,15,16,20,21}.
