pls i have limited time!

(c) Consider two relations called Ri and R2. The number of tuples in Ri and R2 are ti and t2 respectively. The number of attributes of Ri and R2, on the other hand, are ni and n2. (ti, t2, ni, n2 >= 1). Fill in the blanks with formulae containing ti, t2, ni, n2, functions, and constants. Each correct answer - 2 points. If we apply RESTRICT operator to the relation R1, the result will contain a minimum of and a maximum of tuples. The result relation will have a minimum of and a maximum of attributes. If we apply PROJECT Operator to the relation R2, the result will contain a minimum of and a maximum of tuples. The result relation will have a minimum of and a maximum of attributes. Assuming that R1 and R2 are union-compatible, If we UNION R and Rz relations, the result will contain a minimum of and a maximum of tuples. The result relation will have a minimum of and a maximum of attributes. if we AJOIN R1 and R2 over an attribute (or a set of attributes), the result will contain a minimum of and a maximum of tuples. The result relation will have a minimum of and a maximum of attributes
