4. Veterinarians sometimes need to know the body surface area of an animal in order to determine the proper dose of medicine. The expression 0.1mi gives the
approximate surface area in square meters of a cat with a mass of m kilograms.
What is the approximate surface area of a cat with a mass of 8 kilograms? Explain
how you determined
your answer.

1- 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.2- 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 the first question?
