We know that the ocean floor has a depth of 247 ft, and we also know that the diver is<span> underwater at depth of 138 ft, so its distance from the ocean floor will be:
</span>

ft
<span>
Now, the </span>rock formations rises to a peak 171 to above the ocean floor, so to find <span>how many feet below the top of the rock formations is the diver, we are going to subtract the distance to the driver form the ocean floor from the rock formations height:
</span>

ft
<span>
We can conclude that the diver is 62 feet </span><span>
below the top of the rock formations.</span>
Answer:
3' 6" left
Step-by-step explanation:
6' 11" = 83"
10' 5" = 125"
125 - 83 = 42"
42" = 3' 6"
Answer:

Step-by-step explanation:
Given

Required
The inverse

Replace f(n) with y

Swap positions of y and n

Make y the subject

Replace y with f'(n)

Answer:
C
Step-by-step explanation:
For
to be conservative, we need to have



Integrate the first PDE with respect to
:

Differentiate with respect to
:

Now differentiate
with respect to
:

So we have

so
is indeed conservative.
