Answer:
After 15 minutes, the temperature of both the furnaces will be same.
Step-by-step explanation:
Let be the minutes when the temperature of both becomes same.
Now, as per question:
Temperature of the furnace after minutes that is cooling at the rate of 15 degree per minute is given as:
Temperature of the furnace after minutes that is heating at the rate of 5 degree per minute is given as:
Now, equating both the temperatures, we get
Therefore, after 15 minutes, the temperature of both the furnaces will be same.
Given:
First, let us find two points from this equation.
We can set values of x and then solve for y.
Let us find the values of y when x = 1, 2, 3, 4, 5
We now have a set of points:
(1, 21)
(2, 16)
(3, 11)
(4, 6)
(5, 1)
Since the given plane is limited to values of 10 and -10, the points that we can plot are the points (4, 6) and (5, 1)
The graph would then look like this:
