Andrew is paid $4 per hour for the first 30 hours he works each week. he makes $5 per hour for each hour he works over 30 hours per week. in other words, total wages = fixed wages for 30 hours additional wages at $5 per hour. the amount of money that andrew earns varies depending on the number of hours above 30 hours that he works. write the function for the four inputs listed, 32, 36, 38,40. part cexplain how this real-life situation is a function. what are the function’s input, output, domain, and range?

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?
