The area of the blue region A_B is :
A_B = (768)[ (7 + 30√2)^½ + 2 ] - 1408π ≈ 2511.9783 square unit (4 d.p)

Confirm. I can show my working if you want.
Cc. ifada123

Show workings sir. Is like you approximated too early
But very close, show workings let me detect your error sir.

dejt4u:
yea.. I noticed that too. my final answer is 2489 sq. unit

Correct √√√√√√√√√√ (10/10)

You can show your workings for others to learn from it

dejt4u:

Your error

The breadth is not the sum of diamter of one big circle and one small circle,
It is the sum of one small circle and and unknown value which you have to calculate for.
Try it out

dejt4u:
answer is 3257 sq. unit

Show your workings let me detect your error sir

dejt4u:
answer is 3257 sq. unit

No sir try again sir

Lass lass school na scam crew,
When you didn't even got the education,
If you can do this and you are still unemployed,
You need to answer some questions

Martinez39:
If you any maths questions, bring it here.

Check on my post u will see maths questions.
Good to see someone that is interested in mathematics

dawno2008:
Everyone can be a mathematician or a scientist,there are other sectors that improves human existence too,so if I or my children don't know this does not make me a failure

You that know,let your impact be felt,not looking down on who doesn't know

I like your disposition very matured!.
But will u speak calmly like this to a child that made a mistake in English language, not to forget that English is just a subject like mathematics.
My opinion: the way we treat mathematics is not fair.
We make joke with us not understanding it and everyone laugh, but if anyone try that in English everyone including the village people begin to advice him of how he need to improve for his good.

LuciferYaweh:
The area of the blue portion is Agege because that is the only area I know where structures can be jam-packed like this.


*spits

What ?
My friend if u can't do it, wait for others to do it, before u are speaking a language I can't understand

Find the area of the purple portion.

.find the area of the blue portion.

X^logx=10000x^3

With workings

imonisweet:
Bros you sure say this your question legit so

Yes very correct,
If you don't mind send me ur Facebook name via Micah ifada
I will add u to message group were we play with maths.

Bizmagnet:
First find the log of both sides
Log(√2 +1)^x+ log (√2 -1)^x = log34
xlog(√2 +1) + xlog(√2 -1) = log34
x[log (√2 +1) + log(√2 -1)]= log34
xlog[(√2 +1)(√2 -1)]=log34
xlog(2-1) = log34
x = log34/log1
x=log34-log1
x=1.5315-0= 1.5315

U try but ur assumption is not accurate
If a+b=c
Loga +logb is not equal to logc
Rather
Log(a+b)=logc,
Try again sir

ositadima1:
This thread is for a specific problem, their are other place where you can post ur math questions.




Easiest solution is to plot (√2 -1)^x + (√2+1)^x = y

and find x at point y = 34

I am aware of that graphical method,
I would like if u can solve numerically

ePlanet:
is the sq rt covering everything in both brackets?

The square root is covering only 2

ePlanet:
Let Nina's age be denoted with x, her mum's denoted with y and her dad's z

From the questions,

y= 2x....... Equation 1
y + 5 = z...... Equation 2
x+ y +z = 100 ..... Eqn 3

Substituting eqn 1 into eqn 2 for your

2x + 5 = z..... Eqn 4

Substituting for eqn 4 into eqn 3 for z

x + 2x +2x + 5 = 100

Adding items with x

5x + 5 = 100

Subtracting 5 from both sides,

5x = 100 - 5

5x = 95

Divide both sides by 5

x = 95/5

x = 19

Substituting 19 for x in eqn 1

y = 2(19)

y = 38


Substituting for x and y in eqn 3

19 + 38 + z = 100

57 + z = 100

Subtract 57 from both sides

z = 100-57

z = 43

Recal that x denotes Nina's age, y her mum's and z her dad's.

Therefore,

Nina is 19

Her mum is 38

Her Dad 43

Math and physics. Best subjects ever! And, of course ,English.

Try this sir
Solve
(√2 +1)^x +(√2 -1)^x=34

Post a maths question or a part of a topic u find difficult to understand, then u get a simple explanation or solution to it,
And possible an intuition or mnemonics to remember the concept.
This is a free service open to jamb students only.
I remain Mr Shape.

Hi,
Solve (√2 -1)^x + (√2+1)^x =34

A girl went to school and the teacher asked, how old are you? She replied I don't know but I know that I'm half my mother's age.

The teacher asked OK how old is your mother? She said I don't know but I know that my dad is 5 years older than my mother.

The teacher, then asked how old is your dad? She said I don't know but I know that if we add our ages the answer is 100 years...

Now, how old is the girl, her mum, and her dad?

Please show your workings!

The first time I see mathematics on niaraland front page. U most be a friend to a mod.
Any which way.
I need more maths

masterpiecer:
Na so.
After dem don help u find d ansa finish

That is too basic my jss2 will solve it
You solve this
X^(logx3) =10000x^3

bestgift4ever:
Pls I need a Maths and Account teacher for real

Contact me for maths only,
That's what I do.

This trend just prove that a lot of Nigerians don't understand basic maths,
7-15% is very possible for a lending organization,
Alot of market women collect 10k and payback 12k at the end of the month that is even at a high rate of 20%, I can't call that a ponzi scheme, they were closed down for fraud in the system or illegal operation.

Ok
I know it must be a sectarian school.

I have this Toyota Camry 2003 for sale. It is my everyday car and has served me well since May 2018 when I acquired it. I have used it mostly for my daily commute from the Gbagada end of town to Victoria Island.

I have tried to be as detailed as possible:

Toyota Camry LE

VIN: 4T1BE32K13U210268

Style / Body: Sedan 4D

Engine: 2.4L I4 EFI

Mileage as at 30/12/2018: 249,687

(I have attached a Carfax report of the check that I ran at the time I purchased the car).

Car was used by four previous owners before it found its way to Nigeria. I'm the second Nigerian owner. I have not bothered to change the vehicle name to mine. Car still has original owner's name and papers have been renewed in his name.

The AC works perfectly.

Fuel economy is okay. I average about 28-33 miles on every 1000 fuel mostly with AC on. This figure is a guesstimate.

Car has never failed on day. Reliable chap.

Car runs on coolant. Used to evaporate but is now stable.

Reason for sale: I have to free up funds to complete a project.

Summation of the car's condition

-Thermostat was removed and fan was connected directly when I bought it. That has been rectified. Thermostat has been reinstated and fan runs when necessary to cool the engine.

-Car ran/runs on 20w50. After attempts were made to de-sludge it, it was discovered that the system cannot hold synthetic oil. So it still runs on Total's 20w50. I understand that the engine rings are worn. A re ringing has been discouraged by experts

-I must add though that you need an extra 1 litre of oil handy between every 3000 mile cycle. The oil significantly reduces between this interval. This fact wasn't brought to my knowledge at the time of purchase.

- Body work needed for dents acquired on Lagos roads.

Fixes/disclosures.

- Front suspension system needs work primarily caused by bad roads in my area. It has not been touched since I bought it but still drives well. My mechanic's assessment of this is shown below:

Thyrod knuckle 7k
Ball joint 7k
Linkage 5k
Shock absorber 26k
Brake pad 5k
Bushing 7k
Bushing work 2k
Brake lining 7k
Total: 66k

- The back shock absorbers too is giving signs of wear and might need attention too.

- The glasses of the doors do not all whine centrally. Only two can be wound centrally (drivers side and the passenger behind the driver). The front passenger only whines from his side and the passenger behind him doesn't whine at all. One of the buttons is crooked but works.

- because of the car's age (there is no history of flooding as far as I know) there is underbody rust. I have largely ignored it. The panel beater gave me a 33k quote to fix the rust across the underbody and side of the car. See attached photo for rust on the side.

- Although, I have made a full frank disclosure, you are advised not to rely on my representation bring along your mechanic. Car can be inspected on weekdays in Churchgate axis of Victoria Island and in the Gbagada axis on weekends.

Taking into consideration these fixes, I am selling at 750k fixed.

Thank you.

What is the name of your religion ?
And what denomination?

TroubleMaker47:
Am i the only person not understanding this maths?

It was divided by 9 not 12, January to September
They did average per month not per day as they stated there

I believe them more than the army

Hmmm
Story for the gods
I Am sorry for your loss!

Is that not condom sachets behind, about two?

I do buy data online but not with this guy, so don't just label him a scammer when he has not scammed you .
Data sold online is still very real.
Although mtn I do buy is 600 for 1G valid for 3 months.
And it is the code the guy type in his trend that my guy also gave me to check balance data

Anyone?
