Step-by-step explanation:

Hello, we know that the z complex solutions of

$z^4=1$

are

1, i, -1, -i

so, the solutions of $z^4=16=2^4$ are

2, 2i, -2, -2i

Answer: C

Step-by-step explanation:

We are given the information that:

The airplane is at 50,000 feet
It descends 2,500 feet in 1 minute
x = minutes

For ease of solving this question, let's set the number of minutes (x) to 1.

In one minute, we know the plane will drop to 47,500 feet. (50,000 - 2,500(x))

There are multiple ways to write this equation bu shifting around negative and positive values. Another way to write this equation would be (-2,500(x) + 50,000). That would be choice C.

Try it out~

$(-2,500(x) + 50,000)\\ (-2,500(1) + 50,000)\\ (-2,500 + 50,000)\\47,500$

It works, so our answer is C.
