Answer:
4,000 L/h
Step-by-step explanation:
First we'll find the amount of the change.
18,000 - 6,000 = 12,000 L
The time of the volume change was 3 hours: 0230 - 0530
Since we're looking for liters per hour, we will divide the liters (12,000) by the hours (3)
12,000/3 = 4,000 L/h

Step-by-step explanation:
Using the trigonometric identities
cot A =
, tanA =
, cscA =
, secA = 
Consider the right side

= 
= 
=
× sinAcosA ( cancel sinAcosA )
= cos²A - sin²A
= cos2A
= left side ⇒ verified
