Bonfire Temperature In the vicinity of a bonfire the temperature T in °C at a distance of x meters from the center of the fire was given by
At what range of distances from the fire’s center was the temperature less than 500°C?
The range of the distances from the fire’s center where the temperature is less than
Answer to Problem 114E
The temperature is less than
Explanation of Solution
Given:
The temperature T in
Calculation:
To obtain the range of the distances from the fire’s center where the temperature is less than
That is, solve the inequality
Simplify the above inequality as follows.
Simplify further as follows.
Since x represents the distance, x will be positive.
Hence, the temperature is less than
