Inside a room where the temperature is 24.6 oC , a Carnot refrigerator consumes 2,014 W of power while operating. If the refrigerator needs to keep a constant temperature of 5.2 oC in order for the food not to spoil, determine the rate of heat removal from it in kW. (Write your answer in 3 decimal places.)

Idon’t understand! use slope intercept form to solve: through: (2,5) slope= undefined

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?

There are three bags: a (contains 2 white and 4 red balls), b (8 white, 4 red) and c (1 white 3 red). you select one ball at random from each bag, observe that exactly two are white, but forget which ball came from which bag. what is the probability that you selected a white ball from bag a?
