Answer:
The value of x that gives the maximum transmission is 1/√e ≅0.607
Step-by-step explanation:
Lets call f the rate function f. Note that f(x) = k * x^2ln(1/x), where k is a positive constant (this is because f is proportional to the other expression). In order to compute the maximum of f in (0,1), we derivate f, using the product rule.

We need to equalize f' to 0
- k*(2x ln(1/x) - x) = 0 -------- We send k dividing to the other side
 - 2x ln(1/x) - x = 0 -------- Now we take the x and move it to the other side
 - 2x ln(1/x) = x -- Now, we send 2x dividing (note that x>0, so we can divide)
 - ln(1/x) = x/2x = 1/2 -------  we send the natural logarithm as exp
 - 1/x = e^(1/2)
 - x = 1/e^(1/2) = 1/√e ≅ 0.607
 
Thus, the value of x that gives the maximum transmission is 1/√e.
 
        
             
        
        
        
I think isn't anyone of these alternatives because if we put number 15 in the place of y it is x-y=30. X-15=30
X=30+15=45.
X=45
