What is a half-life? Suppose a radioactive substance has a half-life of 1800 years. What fraction will be left after 1800 years? After 3600 years? After 7200 years? What a half-life? O time required for each doubling in exponential growth is called the half-life B. In the case of exponential decay, the value of the quantity repeatedly decreases to half its value with each halving occurring in a time called the half-life. O C. In case of exponential decay, value of the quantity repeatedly increases to half its value with each halving occurring in a time called the half-life. ODNone of the above. What fraction will be left after 1800 years? Type a simplified fraction) What fraction will be left after 3600 years? (Type simplified fraction. What fraction will be left after 7200 years? Box Type simplified fraction)

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?
