Dimas [21]2 years ago
4 0

The matrix is a 2 by 2 matrix, and the determinant of the matrix by hand is -3

<h3>How to determine the determinant?</h3>

The matrix is given as:

1     2

2     1

The determinant of the matrix is calculated using the following product expression

det |A| = 1 * 1 - 2 * 2

Evaluate the product

det |A| = 1 - 4

Evaluate the difference

det |A| = -3

Hence, the determinant of the matrix by hand is -3

Which function is shown in the graph? mc001-1. Jpg mc001-2. Jpg mc001-3. Jpg mc001-4. Jpg.
Elan Coil [88]

The function shown in the graph in the image attached below is y=|x-4|.

<u>Given the following data:</u>

  • Points on the x-axis = (0, 4)
  • Points on the y-axis = (0, 4)

First of all, we would determine the slope of this line by using the following formula;

Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}

Substituting the points into the formula, we have;

Slope. \;m  = \frac{4 - 0}{4 - 0}\\\\Slope. \;m  = \frac{4}{4}\\\\

Slope, m  = 1

Next, we would find the intercept:

Let x = 0, for the y-intercept.

y=mx+b\\\\4=1(0)+b

b = 4

Therefore, the function shown in the graph in the image attached below is y=|x-4|

<h3>What are the building construction members?</h3>

The architectural construction method that consists of two uprights and a crossbeam is called post-and-lintel system. This is because in building construction, a system in which two upright members, the posts, hold up a third member, the lintel, laid horizontally across their top surfaces.

The post-and-lintel system is a simple method of construction involving the use of vertical and horizontal elements. The verticals support the horizontals, creating one Storey of a building. Additional verticals can be placed atop the horizontals to create structures with more than one level.
