The temperature in a room T = T ( t ) is 60 F at time t = 1 (hours). The graph of its rate of change with respect to t is shown in Figure 1. The area of region A in the drawing is 10.9 and the area of region B is 15.4. What is the temperature in the room at t = 4? t 3 4 r (degrees per hour) - 10 - 5 5 10 15 r = T p ( t ) A B 1 (hours) FIGURE 1 Perform the integrations in Problems 2 through 5.
