To find the resultant vector you need to add the horizontal and vertical components of each individual vector.
Cosine for horizontal, Sine for vertical.

Where |v| is magnitude or length of vector.
Lets look at first ranger station. First vector has magnitude 4.5 with angle of 90.
Next has magnitude of 8.1 with angle of 125.


Find magnitude:

Do the same with 2nd ranger station:



Therefore the 2nd ranger station is closest to starting point.
Correct Question: Find the simplified product: 
Answer:

Step-by-step explanation:
Based on the rules of radicals, since
and
has the same index (square root), therefore:

To simplify this, multiply their bases together, and add their exponents.

Answer:
C
Step-by-step explanation:
Recall the equation for a circle:
, where the center is (h,k) and the radius is r.
The given equation is:

Another way to write this is:

Thus, we can see that h=-5 and k=-7.
The center is at (-5, -7).
