-1/2
Step-by-step explanation:
Answer:
k = 3
Step-by-step explanation:
We have the distance formula:
. We can plug in
= d, x2 = 6, x1=2, y2 = 7, y1 = k.
Then, we can solve the question using some algebra to find that k = 3.
Edit: Here is a step by step:









Sqrt(49)*sqrt (-1) -4 = 7i-4
You know when it is a periodic function if the values repeats in regular intervals or periods. An example of this is trigonometric functions that repeat over intervals of 2 pi radians.
