In Exercises 35–42, use technology to find the inverse of the given matrix (when it exists). Round all entries in your answer to two decimal places. [Caution: Because of rounding errors, technology sometimes produces an “inverse” of a singular matrix. These often can be recognized by their huge entries.]
