Answer:
A. Q = 15 °C
B. 0.4 °C
C. Q = 23 °C
Step-by-step explanation:
The following equation models the temperature of Quin's home,
Q = 15 + 0.4t
Where Q is the temperature in degree Celsius and t is the time in minutes
A. What was the temperature when Quinn returned from vacation?
At this time, t = 0 since Quin is just arrived
Q = 15 + 0.4(0)
Q = 15 °C
B. how much does the temperature increase every minute?
0.4(t)
0.4(1)
0.4 °C
The temperature increases by 0.4 centigrade every minute.
C. How much will the temperature increase if Quinn leaves the heat on for 20 minutes
For t = 20 mins
Q = 15 + 0.4(20)
Q = 15 + 8
Q = 23 °C
