A scientist plots a vector on a coordinate grid to record the movement of a migrating whale. The units of the coordinate grid are kilometers, and the positive y -axis on the coordinate grid points north. The vector has initial point (0,0) and terminal point (5,12) . What are the approximate distance and direction of the whale’s movement? A
17 kilometers, 65° north of east

B
13 kilometers, 65° north of east

C
13 kilometers, 67° north of east

D
17 kilometers, 67° north of east

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?
