Answer:216
Step-by-step explanation:
again, we're assuming that both triangles are similar, and thus using proportions.

we do not use the -10, because whatever value "x" may be, can't be negative or even 0.
Answer:

Step-by-step explanation:
When it is converted it is -4.4
First we have to find the derivative of the function:
f ` ( x ) = ( ln x / x^6 ) ` =
=

The critical point is when f ` ( x ) = 0
1 - 6 ln x = 0
6 ln x = 1
ln x = 1/6
![x = \sqrt[6]{e}](https://tex.z-dn.net/?f=x%20%3D%20%20%5Csqrt%5B6%5D%7Be%7D%20)
f ( e^(1/6)) = e^(-1) * 1/6 = 1 / (6 e)
