Answer:
-6x^4 + 7x^3 + 17x^2 -4x
Explanation:
( f x g )( x )
Substitute
[( -2x^2 + 5x -1 )( 3x + 4 )]( x )
Use the Distributive Property
[-2x^2( 3x) + 5x( 3x) - 1( 3x) -2x^2( 4) + 5x (4) -1 (4)] (x)
Simplify
( -6x^3 + 7x^2 + 17x -4)(x)
Distributive Property
-6x^4 + 7x^3 + 17x^2 -4x
Answer: Transmission mode or communication mode is referred to as transmission of data between two devices using a communication channel that includes an optical fiber, copper wires, wireless channels, and various storage media. The data that gets transmitted is in the form of electromagnetic waves. There are various ways of data transmission where the message that is passed is in the sequence of pulses using digital modulation. The transmission mode of data was first introduced in a computer networking system during the 1940s in modems, then in LANs, WANs, repeaters, and other networking system
is this what u are looking for?
the second answer is correct
Answer:
d. all of the statements are correct
Explanation:
Frame Relay is a high-performance WAN protocol that operates at the physical and data link layers of the OSI reference model. i.e Layers 1 and 2 They are designed to cope with bursty traffic. Frame relay is also a form of data networking based on packet switching in which the packets are variable in length and experience packet delays.
Based on the above definition the correct statement is option d as all of the statements define in the other option correctly defines the function of frame relay.
