so their difference is 864π - 648π = 216π.
if we take 864π to be the 100%, what is 216π off of it in percentage?
f(x)=2x+5
first find inverse
write it without f(x)
y = 2x + 5
x = 2y + 5 swap the variables, now solve for y
- 5 -5
x - 5 = 2y
/2 /2 divide both sides by 2
(x-5)/2 = y
so f-1(x) = (x-5)/2
f-1(8) = (8-5)/2
= (3)/2
f-1(8) = 3/2
Answer:
x^5*sqrt(x)
Step-by-step explanation:
5*6 = 30 with one left over
Just plug the inequality in desmos and you get 7<x<13
