The number of yeast cells in a ball of bread dough doubles every four hours. The number of billions of yeast cells in the dough, y, can be modeled by the equation below, where h is the
number of hours since the dough was formed.
y = 5(2)0.251
Which expression is equal to the number of hours it takes for there to be 6 billion yeast cells in the dough?

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?
