Write a method isMultiple that determines, for a pair of integers, whether the second integer is a multiple of the first. The method will take 2 integer arguments and return true if the second is a multiple of the first and false otherwise. [Hint: Use the remainder operator]. Incorporate this method into an application that inputs a series of pairs of integers (1 pair at a time) and determines whether the second value in each pair is a multiple of the first.

Many everyday occurrences can be represented as a binary bit. for example, a door is open or closed, the stove is on or off, and the fog is asleep or awake. could relationships be represented as a binary value? give example.

Suppose there is a relation r(a, b, c) with a b+-tree index with search keys (a, b).1. what is the worst-case cost of finding records satisfying 10 < a < 50 using this index, in terms of the number of records n1, retrieved and the height h of the tree? 2. what is the worst-case cost of finding records satisfying 10 < a < 50 and 5 < b < 10 using this index, in terms of the number of records n2 that satisfy this selection, as well as n1 and h defined above? 3. under what conditions on n1 and n2, would the index be an efficient way of finding records satisfying the condition from part (2)?
