Answer:
i
Step-by-step explanation:
i^ even power
i^2 = i*i = -1
i^4 = =1
So raised to an even power, it will be either 1 or negative 1
raised to an odd power it will be either i or -i
Answer:
Quadrant 1
Step-by-step explanation:
how I understood this is first understanding how a graph works. Once you understand that you can count 13 horizontal on the "X" Axis, then go 18 up on the "Y" axis. you should get a point in the upper left area and that area is called Quadrant 1. Say if 13 was negative instead of going horizontal east you would go horizontal west. And the point should end up in Quadrant 2. Any more questions feel free to ask me below.
