Answer with explanation:
A number of the form , Z= A + Bi, is called complex number ,where A is real part ,whose Domain is set of real Numbers and B is called Imaginary part,whose Domain is also set of Real numbers.
i= Iota =Square root of (-1).=√-1.
Also,→ a number of the form ,K i ,is called Imaginary Number.
P= Set of Complex number={3 i, - 5 i, 6 - i, }
Q=Set of Imaginary Number= {3 i, - 5 i, }
→Following are the Set of complex numbers and Imaginary Numbers, that is ,⇒ P ∩ Q=Common elements of Both P and Q
A: 3 i
B: - 5 i

Answer:
<em>Pool 1 leaks faster than pool 2.</em>
Step-by-step explanation:
<u>Rates of change</u>
The rate of change (ROC) is a measure that compares two quantities, usually to know how fast one variable changes in time.
We are given two rates of change for two pools that are leaking. The first one loses 2/3 gallon in 15 minutes, and the other loses 3/4 gallon in 20 minutes.
To compare them, we are required to express time in hours. Recall one hour has 60 minutes, or equivalently, one minute has 1/60 hours. Converting both times, we have:
15 minutes = 15/60 = 1/4 hours
20 minutes = 20/60 = 1/3 hours
Now compute both rates of change:
Pool 1:
Pool 2:
Comparing both ratios, it's clear pool 1 leaks faster than pool 2.
