So firstly, we have to find f(x) when x = 8 and x = 0. Plug the two numbers into the x variable of the function to solve for their f(x):
Now that we have their y's, we can use the slope, aka average rate of change, formula, which is . Using what we have, we can solve it as such:
In short, the average rate of change from x = 0 to x = 8 is 5/21.
Answer:
Step-by-step explanation:
we know that
If CD is parallel to XZ
then
Triangle XYZ is similar to Triangle YCD
therefore
The ratio of their corresponding sides are equal
we have
CX=5\ units, CY=25\ units, YD=20\ units,
substitute the values
