I’ve been stuck on this so long. i really need . express the quantity of water flowing into a tank as a linear function of time. then identify the quantity of water in
the tank after 50 minutes.
time (min) amount of water (gal)

oy - 1.8x + 219; 317 gal
o y = 0.8x + 209; 317 gal
oy=0.8x + 209; 309 gal
y = 1.8x + 219; 309 gal

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?

Wrote and expression for the difference of p and 4
