Answer:
Yes, it is invertible
Step-by-step explanation:
We need to find in the matrix determinant is different from zero, since iif it is, that the matrix is invertible.
Let's use co-factor expansion to find the determinant of this 4x4 matrix, using the column that has more zeroes in it as the co-factor, so we reduce the number of determinant calculations for the obtained sub-matrices.We pick the first column for that since it has three zeros!
Then the determinant of this matrix becomes:
And the determinant of these 3x3 matrix is very simple because most of the cross multiplications render zero:
Therefore, the Det of the initial matrix is : 4 * 3 = 12
and then the matrix is invertible
For this case we have:
Note:<em> Milliliter is a unit of volume. It is not possible to convert distance units into volume units. </em>
We must convert the length 0.13 meters to millimeters.
By definition, 1 meter equals 1000 millimeters. That is to say:
Then, applying the rule of three we have:
1m ------------> 1000mm
0.13m --------> x
Where x represents the length of the marker in millimeters.
Resolving:
Thus, the marker measures 130 millimeters long
Answer:
130 millimeters
Answer:
20.3
Step-by-step explanation:
1 ml = 0.202884 teaspoons
divide 100 by 0.202884 and you should get your answer
round it to get 20.3
