4. Kennedy and Tess are constructing a racetrack for their horses. The
track encloses a field that is rectangular, with two semicircles at each end.
A fence must surround this field. How much fencing will Kennedy and Tess
need? Use the PI button NOT 3.14. Round to the nearest tenth. Label your
answer for example "meters".

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?
