Line L is tangent to the graph of y= x- (x^2/500) at the point Q

a) find the x coordinate of point Q

B) right an equation for line L

C) suppose the graph above were a hill (measured in feet). There is a 50 foot tree growing vertically at the top of the hill. Does a spot light (a point P, on the x axis along the line L) shine on any part of the tree?
