The scalar product can be described as the magnitude of b times the component of a that is parallel to b. in terms of the positive scalar quantities a, b, and d, what is the component of a that is parallel to b? suppose that c = 0.

1- what do you think the product of a nonzero rational number and an irrational number is? is it rational or irrational? make use of variables, the closure property of integers, and possibly a proof by contradiction to prove your hypothesis.2- why do we have to specify that the rational number must be nonzero when we determine what the product of a nonzero rational number and an irrational number is? if the rational number were 0, would it give us the same result we found in the first question?
