Let's assume we have two sets
First set is A
second set is B
we know that
Union of two sets is the set that contains elements or objects that belong to either A or to B or to both.
So, it does not leave any element from any set
So, for union of two sets to become null , sets A and B won't have any element
For example:
set A={ }
set B= { x : for all real value of x ,x^2 +1=0 }
Since, set B won't have any elements
so,
A∪B=Ф
Yes, the union of two sets have a solution of a null set........Answer

Answer:
Step-by-step explanation:
To find the distance between any two points, we can use the distance formula.
The distance formula is:
Let (2,8) be x₁ and y₁ and let (7,7) be x₂ and y₂. Thus:
Simplify:
Square:
Add:
And that's our answer :)

Answer:</h2>
The error interval for x is:
[3.65,3.74]
<h2>
Step-by-step explanation:</h2>
The number after rounding off is obtained as:
3.7
We know that any of the number below on rounding off the number to the first decimal place will result in 3.7:
3.65 3.66 3.67 3.68 3.69 3.70 3.71 3.72 3.73 3.74
( Because if we have to round off a number present in decimals to n place then if there is a number greater than or equal to 5 at n+1 place then it will result to the one higher digit at nth place on rounding off and won't change the digit if it less than 5 )
Hence, the error interval is:
[3.65,3.74]
