We can calculate the length of AB using the Pythagorean Theorem, where:

So, replacing PA by 34 and PB by 16 and solving for AB, we get:

Then, AC = AB + BC, But AB = BC, so:
AC = 2*AB
Replacing AB by 30, we get:
AC = 2*30 = 60
Answer: AC=60
Answer:
In terms of negative correlation, I would say it's the longer you exercise, the more you sweat.
The correct choice is w-23=84.
Letting w be the number of wolves on January 1, we know that there are 23 fewer the next year which is given by w-23. We also know that this is a total of 84, so w-23=84.
