Chegg how many solutions are there to the equation x=e^(-x)? will the iteration xn 1 = e^(-xn) converge for suitable choices of x0? calculate the first six iterates when x0=0.

The figure shows triangle def and line segment bc, which is parallel to ef: triangle def has a point b on side de and point c on side df. the line bc is parallel to the line ef. part a: is triangle def similar to triangle dbc? explain using what you know about triangle similarity. part b: which line segment on triangle dbc corresponds to line segment ef? explain your answer. part c: which angle on triangle dbc corresponds to angle f? explain your answer. asap
