114 In the vincity of a bonfire the temperature T in degrees

114. \"In the vincity of a bonfire the temperature T, in degrees celcius, at a distance of x meters from the center of the fire was given by T=600,000/(x^2+300). At what range of distances from the fire\'s center was the temperature less than 500 degrees celcius?\"

Solution

114)

T=600,000_/(x²+300)

temperature less than 500 degrees celcius

600,000_/(x²+300)<500

=>(x²+300)>600000_/500

=>(x²+300)>1200

=>x²>900

=>x>30

temperature less than 500 degrees celcius for the distances from the center that is morethan 30 meters

x(30,)
