Let U be a square matrix such that Upper U Superscript Upper TUequalsI. Show that det Uequalsplus or minus1. Assume that Upper U
Superscript Upper TUequalsI. Since the desired result is that det Uequalsplus or minus1, an intermediate step must be found which contains the expression det U. Which of the following can be applied to the assumption Upper U Superscript Upper TUequalsI to achieve the desired result? A. det (Upper U Superscript Upper TU)Superscript negative 1equalsdet I B. det (Upper U Superscript Upper TU)equalsI C. (Upper U Superscript Upper TU)Superscript negative 1equalsISuperscript negative 1 D. det (Upper U Superscript Upper TU)equalsdet I Simplify the right side of the equation found in the first step. nothing Which property can be used to simplify the left side of the equation found in the first step? Select all that apply.
Percentage of pages of a book read by Katie = 32% Total number of pages of the book read by Katie = 80 Let us assume the number of pages that the book has = x Then (32/100) * x = 80 32x = 80 * 100 32x = 8000 x = 8000/32 = 250 So the book has a total of 250 pages in it. Then The number of pages that Katie still needs to read = 250 - 80 = 170 So Katie needs to read 170 more pages in the book.
