During an exploratory activity, a student measured the diameter and circumference of several circular objects. She recorded her
data in the table below. What equation best represents this data?
y = 6.28x
y = 3.14x + 6.28
y = 3.14x
y = 6.28x + 3.14
y = 6.28x
y = 3.14x + 6.28
y = 3.14x
y = 6.28x + 3.14

Answer:
The expression used to find the change in temperature per hour is Algebraic expression
Thus per hour; the temperature falls at the rate of
Step-by-step explanation:
A temperature falls from 0 to in
Which expression finds the change in temperature per hour.
From the above given information;
The initial temperature is 0
The final temperature is
The change in temperature is
Thus;
-12.25 ° = 3.5 hours
To find the change in x° per hour; we have;
x° = 1 hour
The expression used to find the change in temperature per hour is Algebraic expression
From above if we cross multiply ; we have;
(- 12.25° × 1 hour) = (x° × 3.5 hour)
Divide both sides by 3.5 hours; we have:
x° = - 3.5
x° =
Thus per hour; the temperature falls at the rate of
