Multiple choice A certain population of bacteria doubles every 60 minutes. Beginning with 50 bacteria in thr culture, the population can be represented by the function A= 50(2)^t, where A is the number of bacteria after t numbers of hours. Which of these is the appropriate domain for the function A in the terms given context?

A.) All real numbers greater than or equal to zero.

B.) All intergers greater than or equal to 50.

C.) All real numbers greater than 50.

D.) All intergers greater than or equal to 0.​

1- is the product of two rational numbers irrational or rational? first, make a hypothesis by multiplying two rational numbers. then, use variables such as x=a/b and y=c/d and the closure property of integers to prove your hypothesis. 2- 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. 3- 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 part b?
