The temperature in a room is controlled by an electronic thermostat. The temperatures vary according to the sinusoidal function: y= 6 sin[90(x − 11)] + 19, where y is the temperature (°C) and x is the time in hours past midnight. A) what are the maximum and minimum temperatures in the room?

B) at what time does the temperature first hit 13 degrees Celsius

Graph the system of inequalities presented here on your own paper, then use your graph to answer the following questions: y > 2x + 3y is less than negative 3 over 2 times x minus 4part a: describe the graph of the system, including shading and the types of lines graphed. provide a description of the solution area. (6 points)part b: is the point (â’4, 6) included in the solution area for the system? justify your answer mathematically. (4 points)
