Answer:
A. 6
Step-by-step explanation:
The wording "set A and set B" means you're interested in elements that belong only to both. In your diagram, that is Region II. There are 6 elements that belong to A and B.
AB = 6
_____
<em>Additional comment</em>
"A and B" is also called the "intersection" of the two sets: A ∩ B.
The number you have chosen is the number in Regions I, II, and III. That is the set of elements that belong to A <u>or</u> B. You have identified the "union" of the two sets: A ∪ B. (It might also be represented as A+B.)
Answer:
Step-by-step explanation:
The foci are horizontally aligned, so the hyperbola is horizontal. The center is midway between foci, at (0,0).
y²/a² - x²/b² = 1
a² + b² = 5²
Directrices: x=± a²/5 = ±2
a=√10
b = √15
y²/10 - x²/15 = 1
Answer:
$8
Step-by-step explanation:
To find 10% of a number, move the decimal point over by one. Since the number is a whole the decimal point looks like this
$40.00
Move it once to get 10% which is 4. Then multiply it by 2 to get 20%.
