Pplease help me with this question, I don't understand how to get an answer![]()
A point P needs to be located somewhere on the line AD so that the total length L of cables linking P to the points A, B, and C is minimized (see the figure). Express L as a function of x = |AP| and use the graphs of L and dL/dx to estimate the minimum value of L. (Round your answer to two decimal places. Assume that |BD| = 1 m, |CD| = 3 m, and |AD| = 4 m.)
