Answer:
The solution to the inequality is
x > 2π
Step-by-step explanation:
Given the inequality :
2 - 3cscx > 8
We want to find the solution to this.
2 - 3cscx > 8
-3cscx > 8 - 2
-3cscx > 6
cscx < -2
But cscx = 1/cosx
1/cosx < -2
cosx > -1/2
x > arccos(-1/2)
x > 2π
Answer:
946.10 gallons per week
Step-by-step explanation:
1 cm = 0.393701 inch
Width = 5.0m = 196.85 inch
Length = 12.0 m = 472.44 inch
The volume evaporated weekly is given by:

Converting to gallons:

946.10 gallons of water must be added to the pool each week.
