To convert energy, room temperatures are kept at 68.0°F in the winter and 78.0°F in the summer. what are these temperature on the celsius scale

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:

the masses of the objects and the distance between them

this is poiselle's equation from fluid mechanic in physics. mech eng
