Find the Inverse of a 3x3 Matrix.
First
Find the Determinant of A(The coefficients of e
Proceed towards finding the CO FACTOR of the 3x3 Matrix.
+. - +
A= [ 1 -1 -1 ]
[ -1 2 3 ]
[ 1 1 4 ]
The determinant of this is 1.
Find the co factor
| 2 3 | |-1 3 | |-1 2 |
| 1. 4. | |1 4 | |1. 1 |
|-1. -1 | |1 -1 | |1 -1
| 1. 4 | |1. 4| |1 1|
|-1. -1 | |1 -1 | |1. -1
|2. 3| |-1. 3| |-1 2|
After Evaluating The Determinant of each 2x 2 Matrix
You'll have
[ 5 7 -3]
[3 5 -2 ]
[-1 -2 1]
Reflect this along the diagonal( Keep 5,5 -2)
Then switching positions of other value
No need of Multiplying by the determinant because its value is 1 from calculation.
After this
Our Inverse Matrix Would be
[ 5 3 -1 ]
[7 5 -2 ]
[ -3 -2 1]
THIS IS OUR INVERSE.
SO
OPTION C
Answer:
V = 270 cm³
Step-by-step explanation:
Remember your volume formula: V=<em>lwh</em>
So, plug in all your variables and multiply:
(6)(5)(9) = 270
And we have our final answer!
We conclude that he drove 176 miles on the highway
<h3>how many highway miles did he drive?</h3>
Here we have the equation:
A = (1/18)*c + (1/32)*h
Where A is the consumption in gallons of gas, c is the number of miles driven in the city and h is the number of miles driven in the highway.
Here we know that:
A = 8 gallons of gas.
c = 45 miles
Replacing that in the above equation, we can find the value of h.
8 = (1/18)*45 + (1/32)*h
8 - (1/18)*45 = (1/32)*h
32*(8 - (1/18)*45) = h = 176
We conclude that he drove 176 miles on the highway
