∩ stands for the intersection of the two arrays think a venn diagram in this it would be three
<span>∪ stands for objects that belong to either set
</span>
It would be A <span>∪ B because that set shows objects from both sets
If i'm wrong sorry its been a while since I've practiced or learned it</span>
Step-by-step explanation:
180 degrees is (-a, -b) and 360 is (a, b). 360 degrees doesn't change since it is a full rotation or a full circle. Also this is for a counterclockwise rotation. If you want to do a clockwise rotation follow these formulas: 90 = (b, -a); 180 = (-a, -b); 270 = (-b, a); 360 = (a, b)
Answer: -7 , anything bellow 0 is just - then the number.
Answer:
Option 1 I believe
Step-by-step explanation:
Answer: Hope this helps!
Step-by-step explanation:
Area of a trapezoid formula base a+base b/2*h
Base a is the top length (22.5)
Base b is the bottom length (49.9)
Add those two lengths together (22.5+49.9=72.4)
Divide that by two (72.4/2=36.2)
Then multiply that by the height (36.2*23.8=861.56)
So your area is 861.56
