Answer:
The correct option is option A
A. The statement is false. Each matrix is row equivalent to one and only one reduced echelon matrix
Step-by-step explanation:
The matrix in echelon form is not in a unique form, as such row reduction can yield an infinite amount of answers. However a row reduced echelon form is unique and will give the same answer in every order that the row operation is performed
The statement is false. Each matrix has only one unique row echelon form, therefore, the correct option is option A.
Sqrt(27)+sqrt(48)+sqrt(12)
Sqrt(27)=sqrt(3*3*3)=3*sqrt(3)
Sqrt(48)=sqrt(4*4*3)=4*sqrt(3)
Sqrt(12)=sqrt(2*2*3)=2*sqrt(3)
Add the three to get 9*sqrt(3)
Final answer:
9*sqrt(3)

Answer:
Not a function
Step-by-step explanation:
This is not a function because there are different outputs for the same input.
<u>ANSWER: </u>
Jack picked 10 ears of corn. The amount of corn left is
ears of initial corn.
<u>SOLUTION:
</u>
Given, Jack picked 10 ears of corn.
Now the total corn present is 10 ears.
He and two of his sisters ate two each.
Then, remaining corn = 10 ears – eaten corn
= 10 – 2 (by him) – 2 (by his first sister) -2 (by his second sister)
= 10 – 6 = 4
Now, the amount of corn left in fraction is remaining corn divided by initial corn.
Left over corn = ![\frac{remaining corn}{initial corn}](https://tex.z-dn.net/?f=%5Cfrac%7Bremaining%20corn%7D%7Binitial%20corn%7D)
![= \frac{4}{10} = \frac{2}{5}](https://tex.z-dn.net/?f=%3D%20%5Cfrac%7B4%7D%7B10%7D%20%3D%20%5Cfrac%7B2%7D%7B5%7D)
Hence, the amount of corn left is
ears of initial corn.
