Which complex number has a distance of StartRoot 17 EndRoot from the origin on the complex plane? 2 + 15i
17 + i
20 – 3i
4 – i

4 - i

Step-by-step explanation:

Intuitively, the answer will be 4 - i, as the other numbers are too big to have a square as small as 17i.  Also, we know that  i will not be in the end result, which means that we should have a negative in the result as well.

To test this, we can simply treat 4 and -i as the sides of a right triangle and find the hypotenuse:

So indeed the answer is 4 - i

yes   because as the functions are graphed they eventually will intersect unless otherwise
