Answer:
Step-by-step explanation:
x²+y² = 5²
3²+y² = 25
y² = 16
y = ±√16 = ±4
Since the terminal side is in quadrant IV, y = -4
sinθ = -4/5
I'm pretty sure it was Step One. When you multiply -1/4, I don't think the symbol is supposed to change to an addition sign. It's supposed to still be a minus sign.
Answer:
y=12
x=48
Step-by-step explanation:
Relationship shows that
y=1/4x
if we put y=12 and x=48 it holds.

Step-by-step explanation:
Your Universe is D, set B ={swimmers}, set C = {weightlifters}.
First, you are looking for what is either swimmers or weightlifters and that is given by the union of sets B and C: B∪C
Then, you have to look for everything that is not swimmers or weightlifters, and that is the complement of the previous set: ¬(B∪C)
An other notation could be everything that is in the Universe which is not a swimmer or a weightlifter: D - (B∪C)
The area will be therefore the one outside the circles.
