This room has become so noisy these days.

Anyway, I salute all of una o...

Umartins1:
M² + n² = 29 ...... (1)
M+n=7....... (2)


From eqn (2), m+n= 7

M= 7-n


Sub for m in eqn (1)


(7-n)² + n² = 29


(7-n)(7-n) + n² = 29


49-7n-7n+n²+n² = 29

49-14n+2n² = 29

2n²-14n+49-29= 0


2n²-14n+20= 0


n²-7n+10= 0


n²-5n-2n+10= 0


n(n-5)-2(n-5) = 0


(n-2)(n-5) = 0


n=2 or n=5


When n=2,


Sub for n in eqn (2)


M+n=7


M+2=7


M= 7-2


M= 5



When n=5


Sub for n in eqn (2)


M+n= 7


M+5= 7


M= 7-5


M= 2

Well done bro. I wouldn't advice any jambite to use this method though because of the time constraint. Instead, I'll enjoin them to use the trial by error method, i.e. try each of the options in equation 2 as that wouldn't take more than a few seconds and if peradventure, more than one of the options work with equation 2, screen them out with the equation 1.

Affirmative Sir

Here you have it. Sorry for the late reply

bawz012:
16cm ...... corrected

Do you still need help with the solution?

bawz012:
pls check dis out...

The total lenght of a spring when a mass of 200g is hung from it's end is 14cm, while it's total lenght is 6cm when a mass of 30kg is hung from the same end. Calculate the unstretched lenght of the spring assuming Hooke's law is obeyed.

This question is a bit illogical because extension is directly proportional to the load so the more the load, the more the extension. In other words, it is impossible to have a total length of 6cm by a mass of 30kg when you have 14cm for just a mass of 200g(0.2kg) on the same spring. So check and rectify the error. However, after correcting the error in the values, you can then use the formula:
F1/(L1 - l) = F2/(L2 - l)
Where F1 and F2 are the weights of the two masses, (L - l) the extension while L1 and L2 represents the total lengths(extended) of the spring when the 2 masses were hung from the end of the spring and l is the original length(unstretched) being requested from the question.

is it jiayu.es App

Yah

donkripton:
guys i have Jiayu G4S with Jellybeans OS but i want to upgrade the OS to newer version.

i will be happy if someone can give me the link to the new OS for download and how to do the upgrading.

thankyouJesus:
Thanks so much op, God will bless your hustle.
Cc; You all need to be here

Thanks bro

I hail thee my Oga for the wonderful with you're doing here. Although I'll suggest that questions should be asked and answered in details pertaining to the topic at hand instead of giving a kind of note. I'll be around to help henceforth when needed

Good morning guys.
You recent conversation about indomie and garri reminds me of a dude with a crazy food combination. He loves seasoned chief indomie and garri like Kilode.
Anyway, my own special combination is Cold eba and hot beans(the one with epo pupa) . You guys got to try it out...

See y'all laterlater

adexeli:
Like seriously, when mobdro is still alive and there's Etisalat Free Browsing. I'll pass

please, which of the sport channels on mobdro shows live premier league matches?

Please house, I'll like to know if I can use the cwm recovery I did in my phone on another jiayu F2 without consequences?

Lstar4real:
yeah so cool I will update it Tomorrow because my data almost finish

Aiit bro

Lstar4real:
update received Just now on my mobile Phone

wow, cool. Oya update sharp sharp.

As you can see from the name, @Youngzedd, it's a lollipop Rom just like other people who have received it earlier reported

PrinceCEE:
My nigga, I sight u big time....


According to Aristotle, " In an intellectual debate, both parties are right in what they affirm but wrong in what they deny".




Some don't even understand what they're studying. I don't blame u guys but I put the blame on the government for not providing the requisites for education.


Mathefaro, we'll see in school na

Yes bro, by God's grace

@thankyouJesus, thumbs up for the wonderful with you're doing here.

[email] Differentiation and integration gives me a headache [/email]

Eyaah! This shouldn't be the case cos it's a very interesting topic. Trust me, you'll agree with me once you get on with it. And don't worry, JAMB will only set questions at the surface of the topic.

I'll be available for any assistance you guys might need. And for more effective and faster response, contact me

Temiel:
Okay, thanks. Reg starts on feb 13 right?

Yah, and runs through to April 25.

Hmm! Page 505 already, moving steadily....

Youngzedd:
I don't believe that until tomorrow.

Xiaomi have stopped update of kitkat last year.

Issokay, tomorrow it's here already. BTW, I'll also be Very happy if we can get the May update sooner than later

Youngzedd:
Good news!

Android M is coming tomorrow. (My thought because Xiaomi no longer release update on Kitkat. Currently Mi 3 and 4 is running on kitkat) This update is likely to be Android M.

#MIUI 7.1 global stable build is to roll out on Jan.5, 2016! Devices getting this update are Mi 3, Mi 4, Mi Note, Mi 4i, Redmi Note 4G, Redmi 2 / Prime, Redmi 1S, Redmi Note Prime, Redmi Note 2, Redmi Note 3G, and Mi Pad. Yours by design! Get ready for another awesome upgrade! See more:

With Xiaomi, OTA is sure. Mi 3 is 2013 flagship device.

It's not android M. People confirmed it's still KK for Mi 3 & 4

Temiel:
Good morning, please where did you get the calendar?

Mawnin bro. Got it from some departmental excos(Osas, Gift & co) on whatsapp.

misspresident:
seen thanks.

You're welcome dearie

Khan1993:
pls what does it say. Cnt view d tin. Thanks

Oh! sorry for the late response. The summary of what's in the picture is that first semester runs between Feb. 13 and June 10 when we go for mid season break, while the second semester runs between July 4 and December 12

Recently adjusted UI calendar.

At least something to keep the thread going

lexiconkabir:
bro, only a mathematician can tell you that what is in that pics is woefully wrong, i can also prove it to be 3,4,5,6,... using another dubious method, ever heard of anything called infinite solution? an infinite solution is an arbitrary number in the real axis, so 2,3,4,5,6,7 and so on are solutions to 0/0, what the person did was to find that of 2, also 3,4,5,... can be found too, dont be deceived! durrent did you fall for this?

Thumbs up

sholikay:
check the workings very well,its just a case of expanding and dividing like terms..

so you're assuming 0/0 is just 1 all in the sake of dividing like terms? SMH!

I just don't understand why this argument must hold. Must there always be a superior?
May God help us in this country o

Interesting!

misspresident:
lol happy new year.

Thank God last year is gone and now I can reply you. Wishing you the same over here. May this year be our year of breakthrough in all our endeavors

As nobody remember my own moniker, I don vex . I won't talk to anyone of you again this year.

misspresident:
we are all preparing..........as u can see.......@_@ this thread is so dry lol that's the result of the preparation.

I seeeeeee

Compliments of the season to y'all. I hope preparations got resumption are going simultaneously with the festivities

Abusule007:
My redmi note 2 came with miui 7 developer build. So far I'm enjoying it but i can't install twrp in it. I've downloaded different types of twrp for note 2 but it's not installing. Help needed. I need to root.

2ndly, I think there's need for redmi note 2 whatsapp group for easy communication among members. I'm creating one. Please note 2 users, drop your contacts lemme add you guys

nice one

golddeejay:
the only bad review i read abt dis phone is d battery. pls anyone dat has bn using dis fone for a while should tell me how good or bad the battery is.

It actually depends on the ROM you have installed on it. Try the latest Global stable rom. The battery optimization on it is okay
