Consider the following graph, which details the observed bear population in two national parks. A graph titled Bears Observed in Park has month on the y-axis and number of bears observed on the y-axis, going from 37 to 53. In the same month, there are 2 points marked on the graph. All points are connected by overlapping lines. Of the following, which option or options would help make this graph less misleading? I. The scale on the x-axis should be resized. II. The scale on the y-axis should be resized. III. The identity of the two parks should be more clearly differentiated. a. I and II b. II and III c. III only d. I and III
ANSWER IS B

The number of revolutions of two pulleys is inversely proportional to their diameters. if a 24-inch diameter pulley making 400 revolutions per minute is belted to an 8-inch diameter pulley, find the number of revolutions per minute of the smaller pulley.

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?
