The forms of each of the matrices depicts how the row and column elements of the matrices are arranged
The matrix A is in row echelon formThe matrix B is in reduced row echelon formThe matrix C is is neither in row echelon form nor in reduced row echelon formHow to determine the form of the matrices?The matrix A is given as:
[tex]\left[\begin{array}{cccc}4&11&2\\0&-5&8\\0&0&-2\end{array}\right]\left[\begin{array}{c}-6&7&3\end{array}\right][/tex]
The elements on the leading diagonals are: 4, -5 and -2
The elements under the leading diagonals are 0, 0 and 0
When the elements under the leading diagonals are 0, then the augmented matrix is row echelon form
The matrix B is given as:
[tex]\left[\begin{array}{cccc}1&0&0\\0&1&0\\0&0&1\end{array}\right]\left[\begin{array}{c}-6&3&3\end{array}\right][/tex]
The elements on the leading diagonals are: 1, 1 and 1
All other elements in the matrix are 0's
When the elements on the leading diagonals are 1's, and other elements are 0's, then the augmented matrix is reduced row echelon form
The matrix C is given as:
[tex]\left[\begin{array}{cccc}1&0&3\\0&6&0\\7&0&1\end{array}\right]\left[\begin{array}{c}-6&8&13\end{array}\right][/tex]
The above matrix is neither in row echelon form nor in reduced row echelon form, because it does not satisfies the condition of both forms of matrices

A camera is mounted on a tripod feet high at a distance of feet from george, who is feet tall. look at the model to the right. if the camera lens has angles of depression and elevation of , will george's feet and head be seen by the lens? if not, how far back will the camera need to be moved to include george's feet and head?
To capture his feet and head, the camera will need to be moved at least one foot backward. This is an Angles of Elevation and Depression theorem exercise.
What is the Angle of Elevation Theorem?The angle of elevation is the angle between the line of sight and the horizontal line when an observer looks up. While the Angle of Depression refers to the angle that is formed when the observer looks down.
The formulas are given as:
tan θ = y/x ⇒ θ = tan -1 (y/x).
How to calculate the distance required for the camera to capture Geroge completelyLet us assume that x is the distance in feet that the tripod must be moved back.
Recall that the angle of depression and elevation as given in the question (full version attached) is 20°
The height of the Tripod is 4 feet, at a distance of 10 feet, therefore,
tan (20°) * (10 + x) = 4
⇒
x =4/tan (20°)-10
x= 4/(10.989909678 - 10)
x = 0.9899
x ≈ 1 feet.
Hence the camera must be moved back about 1 feet to capture Geroge..
