We are given the following in the question:
A circle centered at origin and radius 5 units.
We have to find the equation of a point that lies on the circle.
Let (x,y) lie on the circle.
Distance formula:
Putting
We get,
is the required equation of point on the circle centered at the origin with a radius of 5 units.

Answer:
-12
Step-by-step explanation:
The average rate of change of a function f(x) on an interval [a, b] is defined as ...
average rate of change = ((f(b) -f(a))/(b -a)
For the given function and interval, this is ...
average rate of change = (f(1.25) -f(0.75))/(1.25 -0.75)
= (4 -10)/(0.5) = -12
The average rate of change is -12 on the interval.
__
The calculator results for f(1.25) and f(0.75) are shown in the attachment, along with the computation of the average rate of change.
