Question: 
Write a function to calculate wind chill index.


Model's Code:
def wind_chill(temperature, wind_speed):
    return 35.74 + 0.6215 * temperature - 35.75 * (wind_speed ** 0.16) + 0.4275 * temperature * (wind_speed ** 0.16)



Sample Correct Code:
import math
def wind_chill(v,t):
 windchill = 13.12 + 0.6215*t -  11.37*math.pow(v, 0.16) + 0.3965*t*math.pow(v, 0.16)
 return int(round(windchill, 0))


Asserts:
assert wind_chill(120,35)==40
assert wind_chill(40,70)==86
assert wind_chill(10,100)==116
