Distance from A to B = 200 miles, Distance from B to C = 300 miles,
Distance from C to D = 540 miles
The speed from B to c is 50% more than A to B . The speed

a.) is the correct answer.

explanation:

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.
