Multiplying -15 by 60 yields -900, so the amount of water in the pool changes by -900 gallons in one hour.
Answer:
.12 km/min.
Step-by-step explanation:
1.8 kilometers / 15 minutes = .12 kilometers per minute
(x - 2)^2 will always be positive and will have a minimum value of 0
so f(x) will have minimum of 2
Range is [2,∞)
<em>Answer:</em>
∠WVR = 156
<em>Step-by-step explanation:</em>
Angles in a triangle add up to 180
∴ ∠SRT + RST + RTS = 180
∴ ∠SRT + 109 + 47 = 180
∠SRT = 24
Alternate Angle Theorem
∠SRT = 180 - ∠WVR
24 = 180 - ∠WVR
24 - 180 = - ∠WVR
-156 = - ∠WVR
∠WVR = 156
Have a beautiful day.
