Answer:

Step-by-step explanation:
Given Equation:

Solving the bracket on L.H.S

Taking the terms of 'x' to one side and the constants to other side

The value of 'x' after solving the equation is:

pi = 3.14...
pi^2 = 9.86...
3^2 = 9
4^4 = 16
Pi is between sqrt(9) and sqrt(16).
Answer:
The running time is quadratic (O(n²) )
Step-by-step explanation:
For the set up, we have a constant running time of C. The, a log-linearsorting is called, thus, its execution time, denoted by T(n), is O(n*log(n)). Then, we call n times a linear iteration, with a running time of an+b, for certain constants a and b, thus, the running time of the algorithm is
C + T(n) + n*(a*n+b) = an²+bn + T + C
Since T(n) is O(n*log(n)) and n² is asymptotically bigger than n*log(n), then the running time of the algorith is quadratic, therefore, it is O(n²).
The answer would be a 28% decrease.
Hope that helps!!
