What does mean for rg 45?
In the context of telecommunications and networking, "RG-45" appears to be a typographical error or confusion with "RJ-45," which refers to a standard connector used for Ethernet networking. RJ-45 connectors are commonly used to terminate twisted pair cables, facilitating wired network connections. If "RG-45" is intended to refer to something specific, please provide additional context for clarification.
What does it mean to have an inverse math problem?
say u r doing division the inverse, opposite, would be multiplacation, same with add and subtract. Hope That Helps, RJ
Why do perfect numbers end in 6 or 8?
This is only true for even perfect numbers; there is no proof that there are no odd perfect numbers, but if one does exist, it has been proved to be in excess of 101500.All even perfect numbers are of the form 2p-1(2p - 1) where 2p-1 is a Mersenne prime - if p is not a prime number, 2p - 1 is also not a prime number (but if p is prime, 2p - 1 may, or may not, be prime).Firstly, other than 2 all primes are odd numbers. So we'll deal with the case when p = 2 separately now:22 - 1 = 3 which is prime, so 22-1(22-1) = 2 x 3 = 6 is a perfect number and does indeed end in 6 (it is 6).To show that all even perfect numbers must end in 6 or 8 when p is an odd prime number requires the use of modulo arithmetic which considers the remainders when numbers are divided by other numbers. In fact, your question is using modulo arithmetic: you are asking why when all [even] perfect numbers are divided by 10 the remainder is always 6 or 8. In mathematical terms this is "why are all [even] perfect numbers modulo 10 equivalent to 6 or 8".Modulo arithmetic is written:a ≡ b mod nmeaning that when a is divided by n the remainder is b and is read "a is equivalent to b modulo n". This can also be written as:a = kn + b for some integer k.examples:24 ≡ 4 mod 10 since 24 = 2 x 10 + 419 ≡ 4 mod 5 since 19 = 3 x 5 + 420 ≡ 0 mod 4 since 20 = 5 x 4 + 0We now need to work out the value ofab ≡ ? mod ngiven that:a ≡ r mod n → a = kn + r (for some k)b ≡ s mod n → b = jn + s (for some j)So:ab = (kn + r)(jn + s)= kjn2 + ksn + rjn + rs= (kjn + ks + rj)n + rs= tn + rs (where t = kjn + ks + rj)→ ab ≡ rs mod nie multiply their modulo equivalences together. [Result 1]if b = a, then this becomes a2 ≡ r2 mod n, ie ax ≡ rx mod n [Result 2]So, going back to the formula for even prefect numbers, we want to know it to modulo 10, so we have:Given:2p-1 ≡ r mod 10(2p - 1) ≡ s mod 10then (from Result 1)2p-1(2p - 1) ≡ rs mod 10 [Result 3]So now we need to look at the results of the powers of 2 modulo 10:(21 = 2) ≡ 2 mod 10(22 = 21 x 2) ≡ (2 x 2 = 4) mod 10(23 = 22 x 2) ≡ (2 x 4 = 8) mod 10(24 = 23 x 2) ≡ (2 x 8 = 16 ≡ 6) mod 10(25 = 24 x 2) ≡ (2 x 6 = 12 ≡ 2) mod 10(26 = 25 x 2) ≡ (2 x 2 = 4) mod 10...You should notice that at this point, that the modulo repeat the four digits 2, 4, 8, 6, 2, 4, 8, 6, ...; so a quick way to find out the last digit of a power of 2 is to take the power modulo 4 and look at that digit of the sequence, but if this is 0, then the 4th digit of the sequence (6) is the result [Result 4]We're almost there, now for the final proof:As p is an odd number (as we are only considering the primes other than 2 (dealt with separately above) and as such they must be odd), it is such that p = 2n + 1 for some integer n, giving:2p-1(2p - 1) = 22n+1-1(22n+1 - 1)= 22n(22n+1 - 1)Using result 3 (and 1) above, we can calculate the remainder of this divided by 10, by multiplying together the remainder of each part divided by 10:22n2n is an even number. Using result 4 above, when this is divided by 4, the remainder is going to be even (2 ≡ 2 mod 4 which is even, and multiplying this by any number will always result in an even number), so 22n ≡ 4 or 6 mod 10. 22n+1 - 122n+1 = 2 x 22n, so 22n+1 - 1 is one less than the next digit in the sequence (of result 4) that gave 22n, ie one less than 8 or 2 respectively. So if:22n ≡ 4 mod 10 → 22n+1 ≡ 8 mod 10→ 22n(22n+1 - 1) ≡ [4 x (8-1) = 28 ≡] 8 mod 1022n ≡ 6 mod 10 → 22n+1 ≡ 2 mod 10→ 22n(22n+1 - 1) ≡ [6 x (2-1) =] 6 mod 10Thus all even perfect numbers end in 8 or 6.QED.
Will NEET be conducted twice in a year in 2021?
The National Testing Agency has not yet confirmed the date of NEET 2021 exam. Resultantly, there is much prediction and speculation about it. Students across India are waiting to hear the dates as they have already received other important exam dates of 2021 such as CBSE 10th, CBSE 12th and JEE. In this wait time and in the effort to forecast NEET 2021 date, a popular hype is that NEET exam will be conducted twice every year. Well, this news of NEET to happen twice in 2021 happened due to a relevant comment by Education Minister Ramesh Pokhriyal 'Nishank' where he confirmed that the ministry is still considering to conduct NEET 2021 twice in a year. However, Ramesh Pokhriyal 'Nishank' did not add any details to this comment and neither further has been heard from the Ministry of Education. Students across India are now waiting for official announcement about NEET 2021, its dates and if it’s happening twice this year. The only official statement that the National Testing Agency made about NEET 2021 is that the NEET syllabus will remain unchanged from previous year. Based on the official statement received by far about the syllabus of NEET 2021, at RJ Vision, teachers have started preparing NEET 2021 aspirants with utmost care such that students are prepared and can perform their best in NEET 2021, whenever the dates are announced.

What is a standard RJ11 or RJ45?
now currently use for rj 45
More about rj 11 and rj 45 cables?
RJ11 and RJ45 are the names for the terminators at the ends of the cables. RJ11 is the 2 pair (4 wire) terminator used for telephones. RJ45 is the 4 pair (8 wire) terminator used for ethernet cable.
Where is an RJ-11 Jack found in the network?
The RJ11 is found in all new homes the jack is found on a wall. thanks
What is a RJ?
RJ stands for Registered Jack commonly used in Ethernet networking. The Ethernet cables has RJ45 connectors at both the ends.
How many wires does the rj11?
The RJ-11 jack has four pins on it but, in normal application, only two are used - the center two, called ring and tip.
What is the difference between rj15 and rj45?
Cat5 cable is the standard cable for computer networking. The "RJ" in RJ15 stands for registered jack. This is the part at the end of a cable that can be used to connect them to computers, phones, etc.
Does the Ethernet port uses and RJ-45socket to connect a laptop to a standard telephone line?
RJ45 was designed for LAN connection only. For modem lines you need RJ11. Thus the answer is NO.
Why Use RJ45 interface in LAN network?
The simple answer is that there aren't enough wires; RJ11 has 4 wires, and RJ-45 uses 8 wires. In addition, the RJ11 wire is not twisted, so there is a problem with crosstalk.
How many wires does the RJ11 has?
RJ11(Registered Jack-11) has 4 to 6 pins. Generally 4 ports are there in RJ11.
What is an RJ-11?
RJ11 is a physical interface often used for terminating telephone wires. It is probably the most familiar of the registered jacks, being used for single line POTS telephone jacks in most homes across the woeld
