The police have _____ him for robbery
a)arrest
b)arrested
c)arresting
Answers
Answer:
b) arrested
Explanation:
Let A and B be sets. The Cartesian Product of A and B, denoted by A×B, is the set of all ordered pairs (a,b), where a∈A and b∈B
. Hence,
A×B={(a,b)∣a∈A∧b∈B}.
Youre forming a set of all the possible ordered pairs where one element is a member of the first set and the other element is a member of the other set.
How would you start this proof or explanation? To me these should be the same because it involves the same operation (Cartesian cross product). Usually when there are three expressions that are applied the same operation, you just go left to right, say 4 * 5 * 6. I don't understand how you would explain A x B x C is not equal to (A x B) x C. To me, using my last example, that's like explaining 4 * 5 * 6 is not equal to (4 * 5) *6.
