Suppose that a car traveling in the west( the negative-x direction) begins to slow down as it approaches a traffic light. Which statement concerning its acceleration in the x direction is correct?.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

the answer is f1 and d2 because if you put equal force on those two points the beam would balance trust me on this
