Please help with the red box. I just can’t figure it out The temperature adjusted for wind chill is a temperature that tells you how cold it feels, as a result of the combination of wind speed, w, in miles per hour, and actualtemperature, T, as measured by a thermometer in degrees Fahrenheit. The table below shows the temperature adjusted for wind chill, f(w,T), as a function of w and T.The left column of the table gives the wind speed in miles per hour, the top row gives the actual temperature in degrees Fahrenheit, and the remaining entries give thetemperature adjusted for wind chill in degrees Fahrenheit as a function of wind speed and actual temperature.w\T15105 0 -5 -10 -15 -20571-5 -11 -16 -22 -28 -34103-4-10 -16 -22 -28-35 -41150-7 -13 -19 -26 -32 -39 -4520-2-9-15 -22 -29 -35 -42 -4825 -4 -11 -17 -24 -31 -37 -44Table of windchills."-51(a) Estimate fu (15, -15) and give a practical interpretation. fw (15, -15) -0.6If the wind is blowing 15degrees Fahrenheit colder for each 1 mph increase in wind speed.(b) Estimate fr (10, 10) and give a practical interpretation. fr (10, 10)~ 1.4mph and the actual temperature is -15If the wind is blowing 1010mph and the actual temperature isdegrees Fahrenheit warmer for each 1 degree Fahrenheit increase in actual temperature.11degrees Fahrenheit, it will feel -0.6degrees Fahrenheit, it will feel 1.4
