Percent of change = (new value - old value)/(old value) * 100
percent of change = (6400 - 8700)/(8700) * 100
For the same reasons as the last problem...
s(n)=20(1-(1/2)^n)/(1-1/2)
s(n)=40(1-(1/2)^n)
But this time we are not starting at one so we must subtract the sum of s(2) from the sum of s(12) so:
40((1-(1/2)^12-(1-(1/2)^2)
40(0.249755859375)
≈9.99 (to nearest one-thousandth)
It’s congruent. The line OL is shared which means it’s congruent for both triangles and since ON is congruent to ED, EN and OD have to be congruent.

Answer:
The notation "f(x)" is exactly the same thing as "y"
Step-by-step explanation:
The effect of using f(x) instead of y is that it allows us to talk about f.
If we have an equation relating X to Y then that's a relationship between rwo nimbers.
For example if you have that y=
![y = {x}^{3}](https://tex.z-dn.net/?f=y%20%3D%20%20%20%7Bx%7D%5E%7B3%7D%20%20)
...then that means that X and Y are some numbers obeying that equation
