What type of service does time safari, inc. provide?

Explanation:

“The Sound of Thunder” is set in the year 2055. Time Safari, Inc. offers time-travel opportunities to hunt and kill exotic and now-extinct animals. In the hunt described in the story, the team of two guides and three hunters goes back to prehistoric days in order to kill the largest dinosaur of them all, a Tyrannosaurus rex. The business has already put safety precautions into place so that these trips can be made without unduly impacting the future. The animals that are killed are ones that have already been identified as doomed. For example, the T rex in question was going to be killed by a falling tree anyway. The safari leaders also built a path for visitors to step on so that no element of the past setting is tampered with. Even the slightest misstep could have implications for the future.

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.
