I NEED HELP ! 7. After conducting an experiment, a science student found that the force, y,
exerted by a hanging object increased as the mass of the object, x,
increased. Which scatterplot could represent the results of the experiment?

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?

Can somebody 1. what is the formula for finding the vertical distance between two points on a coordinate plane?

Which function has the domain x> -11?
