Help me with this please everyone e

false I wouldn't say its a consequence.

layer a is the exosphere and layer b is the thermosphere.   is the answer i think but i hope this .

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.
