The temperature dropped 3°C every hour for 7 hours. What was the total number of degrees the temperature changed in the 7 hours?

21 °C

Step-by-step explanation:

Let's assume the temperature drop (3 °C) per hr is x

This means the total temperature drop would be 7x because 7 hours

7(3°C)=21°C

answer: a) (0,0), (1,1), (2,8), and (3,27).

step-by-step explanation:

0^3=0

1^3=1

2^3=8

3^3=27

in effect, the exponential equation for this would me y=3^x. each x-coordinate cubed is giving the y coordinate, so a is your answer : )
