Bill is concerned about the frostbite risk for workers clearing snow. The weather report predicts the air temperature will be -15 degrees Fahrenheit.
Joe comes up with an equation relating air temperatures caused by the wind and wind speed: y =- 5/ 3 x-38.3
where x is the temperature adjusted for wind speed (in degrees Fahrenheit) and y is the wind speed (in mph).
What is the wind speed, if the temperature adjusted for wind speed is -38 degrees Fahrenheit?
just substitute -38 for x and simplify the result.
Thank you
To find the wind speed when the temperature adjusted for wind speed is -38 degrees Fahrenheit, we need to substitute the given value of x into the equation and solve for y.
The given equation is: y = -5/3x - 38.3
Substituting x = -38 into the equation:
y = -5/3(-38) - 38.3
y = 190/3 - 38.3
y = 63.33 - 38.3
y ≈ 25.03
Therefore, when the temperature adjusted for wind speed is -38 degrees Fahrenheit, the wind speed is approximately 25.03 mph.
