Answer:
see attached
Explanation:
A differential equation solver says the exact solution is ...
y = 5/2 -14e^(-2x) +1/2e^(-4x)
The y-values computed by Euler's method will be ...
y = ∆x·y' = 0.1(5 - e^(-4x) -2y)
The attached table performs these computations and compares the result. The "difference" is the approximate value minus the exact value. (When the step size is decreased by a factor of 10, the difference over the same interval is decreased by about that same factor.)
Negativ numbers no matter how big, will always be less than zero. The correct Answer is A) 45,15,0,-11,-37
Answer:
A HUB
Explanation:
A hub can described as an hardware or network device use for multi purpose functions like connecting series of internet devices together there by making it possible for all devices to work or function together on a single network.
Hubs are classified into active hub, passive hub, and intelligent hub.
ACTIVE HUB: This type of hub boost the signals but can not perform calculations.
PASSIVE HUB: this type only send the signals but can not boost a signal.
INTELLIGENT HUB: it brings about the boosting of signals and also bring about packets to be analyzed.
Answer: Coaxial Cable got its name as "coaxial cable" as it has two physical layer of channel in same cable axis.
Explanation: Coaxial cable is the cable that is basically composed of copper and shield of other materials.They have two physical channels and having a insulating layer between them and the outer layer serving as the ground layer. Both the channel of physical layer have the same axis that why it is termed as "coaxial".These cables are commonly used in the cable televisions , sometimes in telephone line etc.
