Consider the following recurrence and answer the questions given below T(n)= 4T(n/2) + 5n2 i.) a) How many sub problems are in the above recurrence? b) What the size of each of the sub problems identified above? c) What is the work/time needed for non-recursive part (divide and combine) of the recurrence?

The skating rink rented 872 pairs of skates during april and may.why? : if the skating rink rented three times the pair of skates in april during may, they rented 654 skates. 218 x 3 = 654then, if they want to know how many they rented during both april and may, then you just add 654 (may) and 218 (april) to give you 872 pairs of skates for both months.654 + 218 = 872hope this !
