When you want to add a foreign key, the following must be true The foreign key must have the same data type of the referenced column and must refer to a .a O primary key. The foreign key must have the same name and data type of the referenced column; and must b O refer to a primary key. The foreign key can refer to any column in any table. .c O The foreign key must have the same name of the referenced column and must refer to a .d O primary key.

The values of x and y should be swapped. Does the following algorithm work?
than 10, nence y(5) -1.78 which is evaluated according to the expression y = 4sin (x) cos (x) since x(6) is 18.30 which is greater than 10, hence y (6) - -1.78 which is evaluated -according to the expression y = 4sin (x) cos (x) Since x(7) is 5.60 which is less than or equal to 10, hence y(7) = -0.37 which is evaluated according to the expression y = 3sin (5x) cos (3x) >> EXERCISE 19 Write a program using for loop that generates a multiplication table for any integer (given by the user) up to any multiple (also given by the user).
