To find the height of the triangle you will use the formula to find the area of the triangle and the information provided about the area and the base length.
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 f ( e^(1/6)) = e^(-1) * 1/6 = 1 / (6 e) Answer:
