6 [-5 3 0 -4] equal matrix is [-30 18 0 -24]

a collection of numbers lined up in rows and columns to form a rectangular array is called a matrix. The elements, or entries, of the matrix are the integers. In addition to numerous mathematical disciplines, matrices find extensive use in the fields of engineering, physics, economics, and statistics.

<h3>How do you identify a matrix?</h3>

A rectangular matrix is a grouping of numbers into rows and columns. The number of rows and columns of a matrix, in that order, is indicated by the matrix's dimensions. It is known as a 2 3 2 times 3 2 times 3 matrix because matrix A has 2 rows and 3 columns.

The entries or elements of the matrix are its numbers, symbols, or phrases. In a matrix, the terms "rows" and "columns" refer to the horizontal and vertical rows of entries, respectively.

The inventor of matrices is Arthur Cayley. In his Memoir on the Theory of Matrices, which was published in, he gave the theoretical definition of the matrix.

Pls help me math work
3241004551 [841]

Answer:

180.48ft^{2}

Step-by-step explanation:

The area of a rectangle = bh

Area of a circle = πr^{2}

Rectangle = 8 x 10 = 80

Circle = 3.14(8^{2}) = 200.96

But because it's a hlaf circle, divide the number by 2

100.48

Now add the numbers together

180.48ft^{2}

The graph of which function has an axis of symmetry at x = 3?
USPshnik [31]
You do this by converting to vertex form a(x - b)^2 + c   where the axis of symmetry  is x = b

the correct function to have a symmetry x = 3 will be the one which includes -6x
which is the last one 

x^2 - 6x - 1 =  (x - 3)^2 -9-1

the last option is the correct one

Find the dimensions of the closed rectangular box with maximum volume that can be inscribed in the unit sphere.
Anestetic [448]

Answer:

Step-by-step explanation:

Let the rectangle have (x,y,z) as vertex in positive octant.  The rectangular box has to be necessarily symmetrical about all the three axes.

Then the sides of the box would be

2x,2y,2z

Volume = 8xyz

Maximize volume subject to

x^2+y^2+z^2 =1

i.e. g(x,y,z) = x^2+y^2+z^2 -1=0

Use Lagrangian multipliers , we have

∇f(x,y,z)=λ∇g(x,y,z)at the maximum

∇f(x,y,z)=λ∇g(x,y,z) =(8yz,8xz,8xy)\\∇g(x,y,z)=(2x,2y,2z)

8yz=2λx8xz=2λy8xy=2λz

Dividing we get

\frac{y}{x} =\frac{x}{y} \\x^2=y^2

Similarly y^2=z^2

Thus we get 3x^2 =1\\x = \frac{1}{\sqrt{3} }

Hence dimensions are

(2x,2y,2z)

So dimensions are

\frac{2}{\sqrt{3} } ,\frac{2}{\sqrt{3} } ,\frac{2}{\sqrt{3} } )
