Also estimating here as I don't feel like getting a calculator out. Roughly 96 m^2

Though I'm genuinely interested in how the fuck you would solve this mathematically to two decimal places. Seems impossibru with the supplied information.

Add all widths, divide to find average
Add 2m increments, times it by above number
Then find it's square root figure.
It's one of the easiest math questions I have had to do.
READ THE QUESTION CHILDREN
>>706338959
Well apparently it wasn't that easy because this answer is incorrect.
Thanks for playing though
>>706338783
Midpoint rule...
>>706335680
92,32
dunno if its correct, im bad at maths.. but i just took the average height of the pool, which should be 5.77m and the length is 16m. then just multiple this numbers. is it close? :D
>>706339187
which answer was yours anon
71.8222m^2
>>706339142
Well fuck my ass
>>706337822
>>706338783
Took the average of the right side (5) times the distance from 5 to the end (6). = 30
Average of left side (7) times distance (6) = 42
Average of middle (6) times distance (4) = 24
Add them all together = 96 m^2

We are just trying to get an estimate here, it's already a 'close' kind of question. You don't need any more room for error.

JESUS DO YOU RETARDS EVEN HAVE A BASIC GRASP ON MATH? DO YOU KNOW HOW TO DRESS YOUSELVES AND FEED YOURSELVES TOO??
>>706335680
Lol I used to have c++ console programs to do these problems for me. I took c++ 1 the same semester as calc 2. have no idea where the program is now, on some old flashdrive
>>706340913
You seem surprised
80.8 m^2
>>706341091
Python is much better for math problems
>>706340913
I was never really good at math, even in school. I've been out of high school for 8 years, and haven't used anything from that time. So, yeah, not only do I not know any at all how to do the problem in the OP, I no longer give a shit.
The pool is made up of 8 segments that are 2m wide.
The midpoint rule requires that each segment's length is equal to the length of both sides divided by two. So we have the following segment lengths:
Segment 1: (0 + 6.2)/ 2 = 3.1m
Segment 2: (6.2 + 7.2)/2 = 6.7m
Segment 3: (7.2 + 6.8)/2 = 7m
Segment 4: (6.8 + 5.6)/2 = 6.2m
Segment 5: (5.6 + 5)/2 = 5.3m
Segment 6: (5 + 4.8)/2 = 4.9m
Segment 7: (4.8 + 4.8)/2 = 4.8m
Segment 8: (4.8 + 0)/2 = 2.4m
The area of each segment is double the segment length (given its width of 2m). Therefore the total area is simply the sum of the 8 lengths above multiplied by two:
Area = 2m x 40.4m = 80.8 square metres
>>706341234
NOPE haha
I see what you did to get that answer though
80.80 or 72.53 m^2 not sure which method is which.
85.74 square meters
>>706341447
sorry buster but this answer is incorrect
>>706341707
Sorry, it is 80.80 square metres
84 m^2
>>706341282
never learned it, considering it now. I think for this problem the python program wouldn't be much smaller in code lines. My modern physics teacher used python last year for different simulations, I liked the graphing libraries
>>706341863
Again, this answer is INNCORRECT.
Check your math there buddy, I have the answer.
calculate a curve length (sqrt(2+difference)), multiply by height absolute difference, do n times, take sum
i got 95m squared. thats rounded up. i got it by assing all of the 2 meter intervals to find the length of the pool.. thats 16 m. then i added all of the mid lengths then divided my answer by 7 becuase there is 7 intervals. so i multiplied the average width of the pool by its length of 16 = roughly 95m squared
>>706342204
whoops assing --> adding
2*[1/2*[(0+6.2)+(6.2+7.2)+(7.2+6.8)+(6.8+5.6)+(5.6+5.0)+(5.0+4.8)+(4.8+4.8)+(4.8+0)]]=80.8
>>706342168
My math is fine. I know I'm right. You can't prove me wrong.
Nigger I told you. (40.8/9)*16 = 72.53m^2
>>706342484
wrong
>>706342492
You really shouldn't take math personally. When you're wrong, try and figure out why, then try again.
>>706342695
Incorrect, sir
>>706342753
wrong, i made that quiz
this had to do sth with integrals right
>>706341963
Amiright?
>>706342753
>>706342170
I dont want to calculate, but is this method good? This midpoint shit was 2 years ago, and we only use integrals now, so i dont recall.
>>706342828
Well if its not 80.80 or 72.53 then you're doing your math wrong.
>>706342956
haha well you better figure out what you're doing wrong, especially if you're designing quizzes
Do your own homework little fag
>>706342967
yes this has to do with integrals, common I wanna see you be the one to answer this
>>706343198
sorry bro i have no idea how to do it
>>706343076
I literally have the answer in front of me, these two answers are incorrect.
Try something else. Especially if you're claiming two answers, you may realize that you don't know what you're talking about...
>>706342753
I'm not taking it personally. I'm saying that I know I'm right, because the midpoint rule is simple as shit and I applied it perfectly.
Stop fucking with people on the internet.
For everyone else, here is a document that shows an answer for this exact problem using Simpson's Rule: http://orion.math.iastate.edu/rymartin/RUcourses/RU152/hw3_ans.pdf
>>706342967
yeah you need to numerically calculate an integral, and one of the ways to do it is like this:
>>706341447
>>706342484
>>706335680
FFFFFUCK if i know what a midpoint rule is. EU masterrace calculation reporting in.
((6.2+7.2+6.8+5.6+5.0+4.8+4.8)/8)*8 = 46.17m^2 average.

>>706343357
wrong
>>706335680
90 m^2
>>706343581
You're actually slow
everyone don't forget that the sides of the pool are 0 in length and so you still calculate the sum with them, so it will be (0 + 6.2 + 7.2 + 6.8 + 5.6 + 5 + 4.8*2 +0) = 40.4
divide it by 9 because we count the sides,
40.4 / 9 = 4.488888
and multiply by length which is 16
and we get 71.8222
>>706344314
wrong

Nigger I said that in the first 20 posts.
>>706344472
>mfw
>>706344459
OPis officially retarded. You divide by 8 not 9. Answer is 80.80
>>706335680
im not doing your home work anon.
you do mine.
given: f(x,y)=xsin^2(x+y) find: f xyy
>>706345080
why 8 when you have 9 segments?
delete this
I'm a TA for Calc 3. The answer is absolutely 80.80. Any other answer is wrong, obviously
>>706345080
thats what i got as well but >>706345234
there is only 8 segments not 9 delete this
80.40 m^2
>>706345250
Then you're a shit TA
>>706345250
he's never gonna learn if you give it to him. he can use wolfram.
>>706345347
how are there 8 segments? explain or gtfo
>>706345422
Not really, I'm getting my masters in mathematics. I'm smarter and better at math than you will ever be.
But keep being wrong, it's no skin off my ass when you fail your baby calc 1 homework.
>>706345250
this answer is incorrect, TA.
>>706345662
I never thought someone would ask how to fucking count on /b/
>>706345683
prove you are right babyboy
>>706345250
>TA for multi
>thinks he's hot shit
okay
>>706345798
WRONG
wow you guys are really starting to depress me
>>706346018
Fuck off randy you fatass
go suck more dick for cheeseburgers
>>706346029
that literally is the midpoint rule through and through if you think this is wrong then you dont know what the midpoint rule is
>>706346029
you're the one who's begging for help on his easy homework assignment.
post the """""right answer""""" so we can all laugh at you
>>706345683
Lol go ask ur professor then. Don't go thinking you're a bad ass because you're a TA in calc 3. That class is child's play compared to real higher level math courses. Let me know when you take real math courses like analytic number theory or advanced topology.
>>706346165
this.
>>706346228
show us how its done then plz thank you
>>706346101
>a math major with no friends
checks out
>>706345798
this adds too much slack, just average all heights at intervals of 2 including the 0's and multiply by length
>>706346165
>>706346131
>>706346234
>>706346314
aww the babies are getting frustrated, how cute. I know, it's okay, math is harddd.
fucking high schoolers
>>706346228
I've already done those. I'm TA for Calc 3, I'm not taking Calc 3. I've almost got my masters in mathematics.
Maybe you should take Reading for Disadvantaged Adults next semester so you look like less of a fucking moron next time you try to comprehend basic English.
>>706346450
thats not the midpoint rule
the midpoint rule is exactly what I fucking posted
>>706346582
this is no longer believable. no one is this much of a prick.
>>706346720
>waah wahh stop being mean to me
>>706346557
sorry
midpoint rule is exactly what is done here
there is no other way to do a midpoint rule but exactly what this anon did

oh great, one person can count apparently. That's a start /b/
