Which of the following is equivalent to the complex number i^15?

Step-by-step explanation:

The basic relation of the complex numbers is:

So, we decompose in factors of .

So:

Each is replaced by -1.

So:

Any negative value powered to an odd value will be negative. So:

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
