Question

. Se consideran los conjuntos A = (– 7, 3 ), B = [ – 2, 5 ), C = ( – 4, 9 ] y D = [ – 1,8 ]. Expresa cada intervalo por comprensión y calcula A∪B , A'∩B , (B∪C)∩D , (B – A)∪(C – D), (A – B)' y ( B– A)' .

Answer 1

Datos: 

A= (-7,3) 
B= [-2,5)
C= (-4,9] 
D= [-1,8]

Calcula: 

1) A∪B = (-7,3) u [-2, 5) = [-2, 5) 

2) A'∩B: 

A'= (-∞, -7] u[3, ∞) 
A'∩B= [3,5) 

3) (B∪C)∩D

BUC = (-4,9]

(BUC)∩D= [-1,8]

4) (B – A)∪(C – D): 

(B-A) = (-7, -2) U (3,5) 

(C-D)= (-4, -1) U (8,9] 

(B – A)∪(C – D) = (-7, -1) U (3,9]

4) (A – B)' 

(A - B)= (-1, -2) U (3, 5) 

(A - B)'= (-∞,-1) U (-2,3) U (5,∞)

5) ( B– A)'

(B-A)= (3,5) 

(B-A)' = (-∞,3) U (5, ∞) 

Answer 2

Respuesta:

Help, I lost myself again

But I remember you

Don't come back, it won't end well

But I wish you'd tell me to

Our love is six feet under

I can't help but wonder

If our grave was watered by the rain

Would roses bloom?

Could roses bloom

Again?
