Plz answer! I will mark brainliest! Naoki wants to center a canvas, which is 8 ft wide, on his bedroom wall, which is 17 ft wide. Where on the wall should Naoki mark the location of nails, if the canvas requires nails every 1/5 of its length, excluding the edges? Explain your solution process.

A33 gram sample of a substance that's used to detect explosives has a k-value of 0.1473. n = noekt no = initial mass (at time t = 0) n = mass at time t k = a positive constant that depends on the substance itself and on the units used to measure time t = time, in days

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?

If y varies directly as x2 and y=6 when x=6, find the constant of variation.
