Q:
# IM SO CONFUSED PLZ PLZ PLZ HELP! 15 POINTS!This graph shows the temperature of a room over time.What situation could match the graph?(A) Aaron turns on the heat to raise the temperature in the room at the beginning of a conference. The temperature steadily increases until the room becomes too hot, so Aaron turns on the air conditioner. The temperature in the room steadily decreases for a while. When the room gets too cold again, Aaron turns the heat back on and the temperature in the room steadily increases. When the room reaches a comfortable temperature, Aaron turns the heat off and the temperature stays the same for the rest of the conference.(b)Aaron turns on the air conditioner in a conference room and the temperature of the room steadily decreases to a comfortable temperature. The temperature of the room stays the same for a while and then Aaron decides it is too cold, so he turns on the heat and the temperature of the room steadily increases. When the temperature in the room becomes comfortable, Aaron turns off the heat and the temperature in the room stays the same for the rest of the conference.Aaron turns on the heat and the temperature of a conference room steadily increases. After the room becomes a comfortable temperature, Aaron turns off the heat and the temperature in the room stays the same for a while. Aaron’s coworker says it is too hot in the room, so Aaron turns on the air conditioner. The temperature in the room steadily decreases. Aaron gets cold again and turns the heat back on so that the temperature of the room steadily increases. Again, when the room becomes comfortable, Aaron turns off the heat and the temperature of the room stays the same.© Aaron turns on the heat in a conference room and the temperature of the room steadily increases to a comfortable temperature. The temperature of the room stays the same for a while and then people complain of being hot. Aaron turns on the air conditioner, causing the temperature to steadily decrease for a while until Aaron turns the air conditioner off and the temperature stays the same for a while. Finally, Aaron turns the heat back on and the temperature of the room increases steadily for the rest of the conference.(d)Graph in the coordinate plane titled temperature of a room. The vertical axis goes from 0 to 80 in increments of 5 and is labeled temperature in Fahrenheit. The horizontal axis goes from 0 to 90 in increments of 10 and is labeled time in minutes. There are five line segments on the graph. The first segment goes from begin ordered pair 0 comma 65 end ordered pair to begin ordered pair 20 comma 75 end ordered pair. The second segment goes from begin ordered pair 20 comma 75 end ordered pair to begin ordered pair 40 comma 75 end ordered pair. The third segment goes from begin ordered pair 40 comma 75 end ordered pair to begin ordered pair 50 comma 63 end ordered pair. The fourth segment goes from begin ordered pair 50 comma 63 end ordered pair to begin ordered pair 70 comma 75 end ordered pair. The fifth ordered pair goes from begin ordered pair 70 comma 75 end ordered pair to begin ordered pair 80 comma 75 end ordered pair.

Accepted Solution

A:

A line which rises to the right means the temperature is increasing with time . Dropping to the right means temperature is decreasing with time. A horizontal line means temperature stays the same for a period of time.
