Felix is designing a clock. He sketches the design on a coordinate grid. He graphs the shape of the clock with the vertices (–8, 6), (8, 0), and (8, 6 ). Which statement describes the shape of the clock? The shape has three sides. The shape is a quadrilateral. The shape is a circle. The shape has six sides.

What are the domain and range of f(x)=[1/5]x

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?
