You serve a volleyball with a mass of 2.8 kg. The ball leaves your hand with a speed of 35 m/s. What type of energy does the ball have? Calculate the energy. KE = ½ mv^2 PE = mgh

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.

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
