Oliver expects that the number of visitors to a museum(y) is related to the daily rainfall in mm(x). He plots a scatter plot and determines the equation for the line of best fit: y=14.1x+62.0 What is the expected number of visitors when the daily rainfall is 20 mm? Give your answer to the nearest integer.

The table shows the balance of a money market account over time. write a function that represents the balance y(in dollars) after t years.

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?
