A ball is thrown vertically upward. After t seconds, its height h (in feet) is given by the function h (i) = 441–167'. What is the maximum height that the ball will reach?
Do not round your answer

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?
