Pls answer my question :)

U={1,2,3,4,5,6,7,8,9,10,11}

A={4,8,12}

B={2,4,6,8,10}

A union B ( A U B ) = { 2,4,6,8,10,12}

ans: { 2,4,6,8,10,12}

A ∪ B = {2, 4, 6, 8 10}

Step-by-step explanation:

Given the following set notation:

U = {x|x is a counting number less than 11)

A = {x|x is a number divisible by 4 but less than 12} ← This means it doesn't include 12!

B = {x|x is a multiple of 2 between 2 and 10}  

U = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}

The following are the elements of A and B:

A = {4, 8}

B = {2, 4, 6, 8, 10}

Therefore, the union of A and B are:

A ∪ B = {2, 4, 6, 8 10}

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
