The wind-chill index (in degrees C) is modeled by the function W = 13.12 + 0.6215T − 11.37v0.16 + 0.3965Tv0.16 where T is the air-temperature (°C) and v is the wind speed (km/h). When T = −9°C and v = 46 km/h, at what rate is windchill changing as air-temperature increases? (Round your answers to two decimal places.) Incorrect: Your answer is incorrect. °C of windchill per °C of air-temperature When T = −9°C and v = 46 km/h, , at what rate is windchill changing as wind-speed increases?

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?
