Answer:
The first option is the answer (k = +/- 2 square root of J)
Step-by-step explanation:
Since you need to leave k by itself, You multiply both sides by 4 which will leave you with 4J=k^2. To get rid of the square(^2), you need to square root both sides which will leave k by it self. So now you have 4J inside the square root = k. The last step is to take the square root of 4 (which is + or -2) and put it outside the square root sign, leaving J inside the square root.

Answer:
Step-by-step explanation:
We have the two functions: 
and 
.
We want to find 
.
So, let's use the second function to find 
first:
Divide:
Add:
Therefore, our expression is the same to 
.
Now, we can substitute 5 for f(x). This yields:
Multiply:
Subtract:
So:
And we're done!
