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>
They are both equal. 96/12=8
And 8x12=96.
Hope that helped!
Answer:
1. 3.14
Step-by-step explanation:
If we have

That just equals

For example, consider function

The inverse of that function is




So

If we compose the function, f(x) into f^-1(x).
We get

That proof of that.
1. Here x=f^-1(3.14)and f(3.14) cancel out so the answer is 3.14
2. We first find f(-7) which is -12,
We then find f(-12)= 5 so the answer here is 5.
You can evaluate all numbers and in the prosses, make any problem easier.
