It is using the completing the square method.
That's all I will post.

Except it's wrong, brainlet.
>1 - sqrt(1 - c)
>1 + sqrt(1 - c)
These are the only 2 roots.

Hook, line and sinker, /sci/-kun.
I knew you would be here.

all according to keikaku

Why is X = 1 - 2*i*c?

When do we start substituting c for pregnant hamsters?

X=1
C=0

Understanding basic, babby tier mathematics is /sci/ level now?
Guess we've hit a new low (not like we were that high to begin with)

Sci currently has a thread where half the people can't do basic physics.
I don't know if there is a bottom to this abyss but we sure are aiming for it.

No, I meant that I knew someone from /sci/ will try to join this thread, not that OP's problem was /sci/ level.

What do you expect from a bunch of dumb wojakposters?

hahaha
japanese are stupid!!!!

>i
We never had imaginary numbers in high school, I actually don't know the implications of that shit.

Is /sci/ where all the dumb wojacks are coming from?

There are a lot of wojack posters there. I don't do it but I recognize the problem.

Not them, but yes.
And also the smart wojaks and maybe virgin vs chad.

Treat it like you would treat any irrational root, just know that i^2 = -1

I thought the dumb wojack was a Sup Forums spin-off from the 'tfw too intelligent for x''

it's easier to insert c:
c = -x^2 + 2x
x = 1 - 2ic = 1 + 2ix^2 - 4ix
0 = 2i x^2 - (4i+1)x + 1
x = (+-sqrt(15) + (4-i))/4

Smartjak is /sci/, brainlet wojak is /lit/.

>virgin vs chad
that's from r9k

Math time lads.

division comes before
addition and subtraction
answer is 1

9 - 3 / (1/3) + 1
9 - 9 + 1
= 1

>We never had imaginary numbers in high school

Really? Even in Brazil we learned this in school. I remember taking a SAT exam in America and scoring higher than 99% of the population.

Now you're just stealing from the /sci/ thread and putting an anime girl in the picture. I like it.

right

too many unknown factors

/sci/ is a disgrace, there isn't a single informed post there

t. physicist/applied mathematician

...

Didn't have imaginary numbers in Canada either. I only learned about it in 1st year uni.

assuming both spheres have the same volume and the amount of water in both containers is equal.
it tips to the side of the ping-pong ball.

>applied

Correct. But why?

Nope you have everything you need to know.

the water push on ball
ball push back

Hint: You NEED to know Japanese.

It's 3. There is no such thing as division, it's multiplication by the recipricol.
6 / 2 (1+2)
=6*(1/2)*(1+2)
=3*(3)
=9

That is technically true.

9* not 3 xd

Suiyoubi

theres more string in left picture btfo

...

I'm a quant. You want to study topology? Fine, go a ahead. Meanwhile I'm making tons of cash applying stuff while doing research on the side.

Nah doesn't matter that there is more string.

more=more heavy
go to university idiot

The string is made out of neutron star.

go fuck yourself

B

Calling me an idiot doesn't make you any more right.
Did your university education not include buoyancy?

Actually lost my shit a little.

It wouldn't go right, you fuck.

...

You filthy ningen brainlets should be able to solve this

IT'S THE WAITER

Fuck me, I'm wrong.

I want to say 550, but then you're going to tell me 1000 is binary or some shit.

Unless you really believe in proof by intimidation you are still wrong.

>Equation has values such as 900 and 0.5
>Binary

The muslim girl because that's the sort of thing they do.

Could be in duodecimal.

...

Depends on if you want a car or a goat.

I don't know what the fuck buoancy is or how it would affect the scale. No wonder I couldn't cut it in university.

>Study maths on and off for years in high school and engineering/CS school
>6 months into my job after graduation and I've forgotten most of it.
This sure was worth it.

>baby's first probability problem
yes, conditional probability, you always switch blabla, baye's theorem, blablabla

Monty Hall Problem, higher chance of success should you switch doors.

I have barely touched math in years and I feel kind of sad about it.

that's because you are a brainlet that has a job that does not require constant study of math

You're not wrong about that.

3 has spilled infidel blood. The plate and handbag symbolizes her inner emptiness after the deed.

It's 4. He is missing a knife. Could be 1 but we can't see the cuttlery there so it's still unknown to us.

ITT : Sup Forums is filled with brainlets.

I suck at math, gave it all i've got.

Holy shit user, how retarded are you?!
Why are you trying to solve for fucking (i)?!

Water pressure is applied equally on all sides of the steel ball, tension force is applied to the stand on the right. Effectively no change in forces.

Water pressure is applied equally on all sides of the ping pong pall, but the tension force from the buoyancy of the ping pong ball pulls the scale up just a tiny bit.
Weight on the right side > weight of the left side, therefore scale tips to the right

t. got an A in Uni Physics I

>but the tension force from the buoyancy of the ping pong ball pulls the scale up just a tiny bit.

Like a helium balloon. The density inside the ping pong ball is less than it's surroundings, so naturally it pushes upward.
I have no idea what I'm talking about

>Water pressure is applied equally on all sides of the steel ball.
Nope there is a gradient as the water gets deeper that's how buoyancy works.

>buoyancy of the ping pong ball
Why do you think that buoyancy only applies to the ping-pong ball?

>pulls the scale up just a tiny bit
Why would this happen? Is the ping-pong ball filled with helium?

>Weight on the right side > weight of the left side, therefore scale tips to the right.
This is the only part you got right and you got it the wrong way.

>t. got an A in Uni Physics I
You should ask them to take your degree back.

And that buoyant force is transmitted to the water and the beaker counteracting the tension. Net force = the weight of the ping-pong ball and string.

youtube.com/watch?v=QD3hbVG1yxM

A balloon pushes against the atmosphere, the beaker can't pull itself up.

Math is dumb and for nerds. Fuck off with that pretentious shit.

...

Dumb nerds in my Sup Forums? Say it ain't so!

I haven't learned anything about buoyancy yet. I only guessed from my knowledge of free-body diagrams and tension forces.
Thank you anons, I see I have yet a lot to learn.

d. This shit is easy as fuck

>never know if these are supposed to left->right, top->down, or both

The answer is C the bottom left box is an error and should contain a rectangle with an empty circle inside.

>he's studying pure math

All of them

I think it's c
Well fuck me then.
