Answer 1

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
