In this problem, we have given the mattresses on be an oxidant remind video. The pair of each metrics is the inverse off each other. Let's consider it Mac tricks be find metrics. Be post refined, a productive metrics A and B begin the metrics which is equals toe identity mattress. Now they find a productive be into a The result of markets would be my 00 010 three do which is not equal ist white into Demetris Since the product of too many places on either side are not I'd into demand tricks. The given to my prisons are not in rows on each other.

In this question, we have to use technology to find the inverse of the given metrics. There is our metrics. No, we will use matrix algebra tool in order to find the inverse of these metrics. So here is a tool. This is our tool. Now we will enter the given metrics. A hell. We have entered the Cuban metrics. Now we will and the formula Hair, which is in bus. Now we will enter on compute and this is a inverse metrics. So invest matrixes, right 91.35 -8.65 zero -71.3 -0.07 -0.07, Deal 2.49 2.6 2.6 -4.35 1.37 2.69 2.69 zero -2.1. Thank you.

That's that's one for you with this one. Remember? Our are very so this one doesn't have any solution because we have our last Oh, it was us isn't true. Statement, so we can see that. Is this Listen, but right or all right. What are the right reasons so Or money? Sports. Why you gotta wait a solution? We thought so. This is more only work. Not all right.

So in this problem we're given this matrix which Is a diagonal, right, only has entries on the main diagonal. Everything else is zero and were asked to define the determinant. We can use a matrix calculator to do this with. So what you desmond dot com went to math tools matrix calculator and got this one. So I need a new matrix now and I got five rows and five columns. And the first entry up here Is a -2 And then the entry here is a three And the entry here is a -1 man. She just working my way down the main diagonal here, This is a two And the last entry down here is a -4. There's all my entries now to do the determinant. I go d E t of a and We get -48 for the answer. So there you go. Which by the way, if you multiply the entries on the diagonal there. Look what happens When one is 2 times three is -6. I was in -1 is plus six times two is 12 Times of -4 is -48. Gave us the determinant, didn't it?
