Step-by-step explanation:
I'm not entirely sure what you mean by "from the origin", but hopefully this helps.
The distance formula for a Cartesian coordinate system (your standard x-y graph) is .
If you're measuring "from the origin", that just means one of your points is (0,0).
For example, if you were to measure between the origin and the point (1,4) your formula would look like this:
So, the distance between the origin and (1,4) is .
I hope this helps! Please let me know if you have any other questions!
The scaled down size is 1/5 time 14

If the price is now 81 cents and the price was 8% less the price would have been 64 cents.
Answer:
1/3
Step-by-step explanation:
The average rate of change of a function f(x) on an interval [a, b] is given by the formula ...
rate of change = (f(b) -f(a))/(b -a)
__
For the given function and interval, this is ...
(log₂(4·8) -log₂(4·2))/(8 -2) = (5 -3)/(6) = 1/3
The average rate of change is 1/3.
_____
In the attached graph, the line between the points at the ends of the interval can be seen to have a rise of 1 for a run of 3. Its slope is 1/3.
