<u>Given</u>:
Let X and Y be two sets.
The two sets are given by and
We need to determine the value of the set
<u>Value of the set </u><u>:</u>
The value of the set is the set that contains all the elements that are at least in one of the two sets.
Hence, the union of the set is given by
Arranging in ascending order, we get;
Thus, the union of the sets X and Y is
Let's say that the coordinates of the squirrel are: (x, y)
Since the coordinates of the acorn is halfway, between the tree and the squirrel, that means the acorn is the midpoint.
To work out the midpoint you do:
(sum of x-coordinates) divided by 2, (sum of y coordinates) divided by 2.
We can use this to form an equation .
So the sum of the x coordinates of the tree and the squirrel = -1 :
x-coordinates of the squirrel:
<em>(now solve for x)</em>
y-coordinates:
<em>(now solve for y)</em>
So the coordinates of the squirrel are: (1, 2)
