Solve True or False and try bonus.
Highlight (use this or similar color) whether the statement is true or false; 1 pt each. 1. True/False: Given matrix (A), I [A] represents the absolute value of [A]. 2. True/False: While absolute value represents a strictly magnitude value, determinants represent more of a vector quantity. 3. True/False: While absolute value can be fractional, determinants are always an integer. 4. True/False: One application of determinants is to find the volume of a parallelepiped....
