Homework Statement Point A (–4,1) is in the standard (x,y) coordinate plane. What must be the coordinates of point B so that the line x = 2 is the perpendicular bisector of AB ? Homework Equations don't know where to start. The Attempt at a Solution haven't tried.

i have a couple of examples i am working through and i only need to know the differences between 2 equations. this deals with tension. one equation is ma=t-w and the other is almost the same, ma=w-t. my instructor uses both of these but why would you use t-w and then use w-t? one of the...

Homework Statement An 80 N traffic light is supported at the midpoint of a line between two poles that are 30 m apart. If the light sags a vertical distance of 1 m at the midpoint, what is the tension in the supporting line? A 20 lb picture is hung from a nail so that the supporting...
