Assume that the temperatureduring a summer week in
seattle varies sinusoidally with
time. suppose the hightemperature of 74 f occurs
each day at3: 00 pm and the low
temperature of 56f occurs each day at 3: 00 am. on
mondayafternoon at 5 pm you finish
painting the exterior door toyour house. the paint
product information states that 20
hours of 70 f drying time is required; that is, the
paint requires 20hours of temperatures
above 70 f to dry. when will the door be dry?

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?
