Answer:
B.
Step-by-step explanation:
The least amount of water in a pool is zero gallons.
It takes 16 minutes to reach zero gallons (the pool is empty).
The domain is from 0 to 16.
Answer: B.
<span>A(−3, 2), B(−4, −9), C(8, 1)
This is the right answer.
The slope of AB is perpendicular to the slope of BC.</span>

The hypotenuse is the longest side of the triangle. The opposite is the side that is across from a point/angle. The adjacent is the side next to a point/angle.
At ∅ (pretend that's theta LOL), 17 is the hypotenuse, 8 is the opposite side, and 15 is the adjacent side.
So:
sin ∅ = Opposite/Hypotenuse
sin ∅ = 
cos ∅ = Adjacent/Hypotenuse
cos ∅ = 
tan ∅ = Opposite/Adjacent
tan ∅ =
