The wind chill factor represents the equivalent air temperature at a standard wind speed that would produce the same heat loss as the given temperature and wind speed. one formula for computing the equivalent temperature is

w(t) = {■([email  protected](10.45+10√v-v)(33-t)/[ema il  protected](33-t) ) ┤ ■(if 0≤v< [email  protected] 1.79≤v< [email  protected] v≥20)

where v represents the wind speed (in meters per second) and t represents the air temperature . compute the wind chill for an air temperature of 15°c and a wind speed of 12 meters per second. (round the answer to one decimal place.) show your work.
