Identify the augmented matrix for the system of equations.
lord [1]

Answer:

The augmented matrix for the system of equations is \left[\begin{array}{cccc}0&2&-3&1\\7&0&5&8\\4&1&-3&6\end{array}\right].

Step-by-step explanation:

This system consists in three equations with three variables (x, y, z).The augmented matrix of a system of equations is formed by the coefficients and constants of the system of linear equations. In this case, we conclude that the system of equations has the following matrix:

\left[\begin{array}{cccc}0&2&-3&1\\7&0&5&8\\4&1&-3&6\end{array}\right]

The augmented matrix for the system of equations is \left[\begin{array}{cccc}0&2&-3&1\\7&0&5&8\\4&1&-3&6\end{array}\right].

Can somebody help me with this plz?!?
fomenos

Answer:

Step-by-step explanation:

The angle is 60 degrees and a whole circle has a total of 360 degrees, of that makes sense. So if you do 360/60, you get 6. This tells you that 6 of those particular arcs fit into this particular circle.

Find the circumference of the circle. You are given the radius, 3. Use the circumference formula, 2(pi)(r). You get 6pi.

6/6 = 1, so the length of that one arc is just p

Hope this helps!.

In the school library, 28% of the books are non-fiction. If there are 1.224 fiction books in
denis-greek [22]

Answer:

1700 books

Step-by-step explanation:

We are given;

  • % of non-fiction books in the library as 28%
  • Number of fiction books in the library as 1,224 books

We are required to determine the total number of books.

First we determine the percentage of non-fiction books

We need to know that;

% of fiction books + % of non-fiction books = 100%

Therefore;

% of non-fiction books = 100 % - 28 %

                                    = 72%

Second we determine the total number of books

We know that;

Total number of books = 100%

But;

72% = 1,224 books

Therefore;

Total number of books = (1,224 × 100%) ÷ 72%

                                      = 1700 books

Hence, the library has a total number of 1700 books

A cylindrical specimen of cold-worked copper has a ductility (%el) of 25%. if its cold-worked radius is 10 mm, what was its radi
loris [4]

The radius of the cylinder before deformation is 7.5mm

<h3>Deformation of an object</h3>

From the given question, we are given that;

cold work radius of the cylinder is 10mm

Ductility = 25%

Determine the radius before deformation

Radius before deformation = (1-  0.5) + 10

Radius before deformation = 0.75 * 10

Radius before deformation = 7.5mm

Hence the radius of the cylinder before deformation is 7.5mm
