Graphs of Functions

BACKROUND INFO: (Answer from question a)Tidal waves such as the one below do not really follow a normal trigonometric graph of the form $y= k cos at+ c$ So the behaviour of the data instead that preve...

Looking for a detailed step by step solution if possible, it's just an awkward question and I can't figure it out at all

I need to use a substitution method to prove and show that T(n) is in O(n³) for$T(n) = 2T(\lfloor \frac{n}{2} \rfloor) + 5n^3 $ for n ≥ 2, T(1) = 20I am supposed to come up with an explicit guess for...

solve all parts please

thanks
