The shaded area is above the line The line itself is dotted.
Answer:
5.4 hours
Step-by-step explanation:
As the number of hours of daylight y is modeled as a function of sin, and sin has the minimum value of -1. Therefore
So the minimum number of hours of daylight in Anchorage is 5.4 hours
1 gallon = 3.785 liters
Water in pool = 8000 x 3.785
Water in pool = 30,280 liters
Chlorine dosage = 2.5 mg / liter
Chlorine = 2.5 x 30,280
Chlorine = 75,700 mg
To the nearest thousand milligram:
Chlorine = 76,000 mg
