Access now pays 237? Does that mean they now pay more than Gtb? pls who knows the actual take home of entry level in Gtb? No guess pls as I want actual figure.

Sure, Access pays more than GTB. The only bank that I know pays better than Access is Diamond bank but I don't have the precise figures for GTB.

Thanks man...I should brace up

Yeah, and you have to be very careful at the training school, don't be carried away. You must not score less than 65% in each of numerous courses, you can retake a failed course just once and you must pass it the second time. You also have to follow all instructions strictly particularly during exams because once you err, you would be automatically dismissed and that's the end, they dismiss people at the slightest misconduct and this is not the time to go start dating your classmates, you need concentration. You will enjoy the training, the meals, the fun, outings etc. If you score best in any of the courses, you will get a gift. There are fantastics prizes for overall 1st,2nd and 3rd positions. All the best to you!

Very true. You will get 43k per month during your 4 months training and at least 237k per month after training when you resume. My lil sister works there.

I was gonna slap the OP if UNAAB (FUNAAB) didn't make the list. There is no how you will talk about best Unis in Nigetia and Funaab won't be there. Moreover, it is even underated. Funaab is far better than most of these federal unis on the list.

so[b] do you agree na ojoro?[/b] Anyway, I like your love for mathematics. Thanks to you guys on this thread... it just had me going back to some basics. There is a method that could have worked. I cant remember but I guess it would be found in Pure Mathematics text book. That small book with red coloured shapes.

Hahahaha. The ojoro wasn't intentional you know? I have some other challenging maths problems which I was able to solve. I will open a thread for it subsequently and attach a prize to it. Nice day!

Thanks bro. I understand every other process used to arrived at your answer which is mathematically correct but where I am confused is this. can you explain the mathematical principle used here:

You say Let 2^x = P. That's fine. But how is X then = sqrt P? Thanks.

That's what we are saying bro. The rule I used there is wrong.I hurriedly tested it for two values and it worked, so, I didn't bother testing for other values again until mathefero pointed it out. I tested it for values of 2 and 4 . E.g. If 2^(X) = 4, I said X = sqrt 4 = 2 and if 2^ (X) = 16, X = sqrt of 16 = 4. Unfortunately, it was just a coincidence that we got the same answer as the rule is wrong. When you test it with 2 ^ (X) = 8, you know X is supposed to be = 3. If I now say, X = sqrt 8, I won't get 3.So, the rule I used is wrong and we have to find another way to solve that problem.

lemme attempt the question..
Cheat code; pls do nt ask me where i gt the law from

2^x = 4x,
~~2^x/2 + 2² = 4x,~~
then, 2^x/2 = 4 OR 2² = x..
Whichever way, x = 4

I'm sorry bro, there's still an ojoro in your solution o.
if 2^x = p then
x != sqrt(p) ( x is not a square root of p)
you might want to check it out using numbers.
2³ = 8 but the sqrt of 8 is not equal to 3. smiles

Yeah, you are right, it should be if X^2 = P, the X = sqrt (P). That was what was on my mind. Although, I tested the rule with values of 2 and 4 and it worked, that was why didn't bother testing with other values again. Thanks for pointing it out. Men, I no go chop today o.

The same method works for 3^X = 9X when solved to get X = 3. Solution attached below;

Use the inequality values to obtain some figures. When you plot the graph, if there is no break at all when you are drawing the linem then the function is continuous but if there is a break in the line, the function is not continuous. You can check online for how to go about it, I am sure there would be more than enough materials. If I am free and settled, I may attempt plottiing the graph too (not promising o) but if I do, will let you see it.

Thank you very much. Although we were told to plot a graph with the information, which is what I'm pondering. How will that be possible?

Mr. Naturalwaves.
Could you assist me with this question ?

A function of y={×, ×<_1}
. . . . . . . . . . . . . . {2-×, ×>2}.
Judge whether the function is continuous at ×=1. Differentiable at ×=1.
Thanks for the assistance.
.

I think the function is continuous but not differentiable at x= 1 cos after differenciating f(x) , there was no place to slot in 1 at all as it gave outright figures. Check what I got below and review with colleagues as it has been long I did this.

Thanks bro. Some advance maths can be frustrating too.I think the key to that is getting the right textbooks.I observed overtime that some authors just rush through some concepts without a preciseand concise method. Thank God for the internet, one can get more than enough study materials online.

Alright...so far I've been convinced there are great mathematicians in Nigeria....naturalwaves I salute you sir. As for the guyz saying Calculus cannot be applied in real life sense...Ever considered how the equations of motion came into existence?...Cars moves in accordance with our equations. Actually the questions i sent earlier on 're not thd hardest mathematics... I actually framed up this questions with the solutions known.....the password to myPc u guyz supplied were wrong..Did you consider PERMUTATION with repetition?

more questions loading...

Honestly , I have been so bored till I came across this thread. Thanks for making my day less boring. If you actually set those questions, then, I must commend you cos they seem to be application based and requires a bit of deep reasoning. Welldone and keep it up!
