- The Determinant of a Matrix in Exercises 25-30, find |A1|.Being by finding A1, and then evaluate its determinant. Verify your result by finding |A| and then applying the formula from Theorem 3.8, |A1|=1|A|. A=[223112303]arrow_forwardTrue or False? In Exercises 75-78, determine whether each statement is true or false. If a statement is true, give a reason or cite an appropriate statement from the text. If a statement is false, provide an example that shows the statement is not true in all cases or cite an appropriate statement from the text. (a) In Cramers Rule, the value of xi is the quotient of two determinants, where the numerator is the determinant of the coefficient matrix. (b) Three point (x1,y1), (x2,y2) and (x3,y3) are collinear when the determinant of the matrix that the coordinate as entries in the first two columns and 1s as entries in the third column is nonzero.arrow_forwardFind the determinant of the matrix in Exercise 16 using the method of expansion by cofactors. Use a the third row and b the first column. 16. [342631478]arrow_forward
