Brenda (45-kg) sledding down a Roller Coaster at Six Flags Great America from three different heights (10m, 5m, 0m) calculate:

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.

answer; (arch); good luck

1= 26.17

2= 1.17

3=30.86

4=5.86

just took the assigment on edge

the answer is a. hope this .
