The formula to convert degrees in Celsius, c, to degrees in Fahrenheit, f, is f=c+32 .Solve the equation for c, and then use the new equation to find the temperature in Celsius for the temperature -40 Fahrenheit. What is the temperature in Celsius for the temperature -40° Fahrenheit?

A. 8° Celsius
B. 40° Celsius
C. -40° Celsius
D. -8° Celsius

Asequence {an} is defined recursively, with a1 = 1, a2 = 2 and, for n > 2, an = an-1 an-2 . find the term a241

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?
