The figure is a rhombus J' K' L' M' in a coordinate plane, showing all its vertices.

The vertex J' is the point (0, -2).

And the statement indicates that the quadrilateral JKLM was transformed into the figure J'K'L'M' by the dilation (x,y) -> (x/2, y/2).

Then you have to find the preimag of J' which is J.

You know that x was multiplied by 1/2 to transform into 0, then x/2 = 0 => x =0

And y was mutilplied by 1/2 to transform into -2, then y/2 = -2 => y = -4.

And the pre-image is (0, -4)

Answer: (0, -4)

  • The F-connector is a coaxial RF connector commonly used for "wireless" terrestrial television, cable television, and common for satellite television and cable modems, usually with RG-6/U cable or with RG -59 / U.

  •  F connector is also known as threaded connector. There are two main types: 7mm (6.8mm) is the most common and  used in coaxial cable, and 5mm connector  is used in  thin coaxial cable commonly used in satellite system.

  • The F-connector is an accessory that connects a coaxial cable to an electronic device or  wall outlet.

  • Type F connectors are highly mechanical and electrically stable coaxial screw connectors  for cable television (CATV), set-top boxes, cable modems and satellite television applications up to 4 GHz

lys-0071 [83]

The magnitude of the second atom relative to the first = 10⁻¹¹ / 10⁻¹³ = 100

<h3>Equation</h3>

An equation is an expression used to show the relationship between two or more variables or numbers.

The magnitude of the second atom relative to the first = magnitude of second atom / magnitude of first atom

The magnitude of the second atom relative to the first = 10⁻¹¹ / 10⁻¹³ = 100
