Agraduated cylinder is filled with water to the 24-ml mark. when a rock is placed in the cylinder, the level rises to the 53-ml mark. what is the volume of the rock?

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.

explanation:

v=uf/(u-f)

= 5.-10/(5+10) convex lens has negative focal length
