Intersection (repeated element in the set)
A={-9,0,5}
B={0,2,5,8}
C={-9,2,5}
Ans: C, {5}
*In set B and C, element 2 was repeated but not for set A.
B. 12/18
Upon simplifying this fraction (taking a 3 out of the numerator and denominator), you end with 4/6
Using the concept of number line, the solution to the questions posed are :
- <em>Pool</em><em> </em><em>surface</em><em> </em>
- <em>The</em><em> </em><em>height</em><em> </em><em>of</em><em> </em><em>slide</em><em> </em><em>is</em><em> </em><em>12</em><em> </em><em>meters</em><em> </em><em>above</em><em> </em><em>the</em><em> </em><em>pool</em><em> </em><em>surface</em><em> </em>
- <em>The</em><em> </em><em>level</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>bottom</em><em> </em><em>of</em><em> </em><em>the</em><em> </em><em>pole</em><em> </em><em>should</em><em> </em><em>be</em><em> </em><em>marked</em><em> </em><em>as</em><em> </em><em>-</em><em>3</em>
The pool surface would be treated as sea level surface, such that, position below are marked as negative and position above are marked as positive.
- Therefore, the surface of the pool is <em>marked</em><em> </em>as the sea level position, 0.
- Since the slide is above the surface of the pool, it's value will the positive. Hence, the height of the slide is 12 feets.
- The marked position is below the <em>pool</em><em> </em><em>surface</em><em>,</em><em> </em>hence, it will take up a negative value of - 3 feets.
