The acceleration is constant

Can you be immortal if you just clone yourself?

Because your body changes all the time anyways. You are not the same person you were 5 minutes ago.

If you cloned yourself, but your original self died. Could you still be considered alive?

Investopedia explains 'Risk-Return Tradeoff'
Because of the risk-return tradeoff, you must be aware of your personal risk tolerance when choosing investments for your portfolio. Taking on some risk is the price of achieving returns; therefore, if you want to make money, you can't cut out all risk. The goal instead is to find an appropriate balance - one that generates some profit, but still allows you to sleep at night.

Is there an easy way to solve a system like this;

sin(A) - sin(B) = .1663;
cos(A) - cos(B) = .0323;

Is there an identity I could use?

hey /sci/ I'm taking the sat 2 bio in jan 29 but the problem is I don't remember shit from bio tips / advice?
main reason I'm taking it is to allow my hs to let me take both ap chem and ap bio despite my lesser bio grade last year.
(this is all hypothetical I'm not a minor mods)

Objectively speaking, why do you post here? The only things that this would be best for compared to a board are trolls, homework threads, and repetitive threads, the very things this board is supposedly against.

The reason I do is because I want a fast response, but if we all agree to move to the same forum then we can get our fast responses in a archived and accountable environment.

So what forum(s) would you suggest?

I've got seven months before entering University and I want subjects to study.

All precalculus topics (geometry, trig, algebra) already done, as is both sections of AP Physics C (classical mechanics and electromagnetism). I'm already a computer programmer, a relative novice but I'm getting two hours of practice each day and slowly but surely improving.

So - /sci/entists, tell me what you think are the subjects most deserving of attention. (Mentioned topics are out)

is anywhere i could learn maths with other students or a instructor live over the internet or something that can help me self-study? i am doing horrible and the only thing i'm doing is just mechanical math problem solving such as factoring.

also park your fucking elitism because i could kick your ass in real life if you try to act all superior to me just because you have different brains then me.

Can anyone give me an example of an organism that is classified as an animal but doesn't have DNA? I know it's almost impossible, but it doens't hurt to ask.

need some quick algebra help brahs

14 = x/(.3-x)(.7-x)

Can somebody let me borrow their coureshero acct for a day so I can get my fluids fix

! Most igneous activity is related to processes
operating at active plate boundaries
! Most magmas originate at 50 to 200 km depth
! Basalt magma is generated from partial melting of
Peridotite in the upper Mantle
! Granite magma is generated from partial melting of
rocks in the lower crust

Consider a complex function R with derivative R'.

Is there another way to write out Im(R'/R) in terms of R' or R so that I can take derivatives with respect to R?

How long can sperm survive outside the body to make someone pregnant?

I keep hearing that sperm can live for 3 days outside the body which has made me really paranoid about making people pregnant accidently. So does that mean if theres sperm thats 2 days old and a woman manages to get it on her hands and fingers herself, she can become pregnant?

Any Modelsim pros on?

I'm trying to simulate a simple state machine and I have no idea how to go about doing this.

Basically I have to write an entity that acts as the test bench? I'm not quite sure.

Anyone hit me with some insight?>

How do I get over my fear that my sperm from fapping will get someoen pregnant accidently

can anyone help me with this?
review how you use any logical reasoning tools on a daily basis. What tools do you use, and do you note any logical fallacies in your daily routines?
im getting a blank here

IF causality, a fundamental element of sane reality was legit, existence could not come out non-existence.
Logically:
a) time is eternal
or b) reality proceeds either randomly or as externally scripted outside of the universe
c) there is a flaw in my logic...

ok so

was looking up at the night sky just now. noticed how stuff like trees are clearly silhouetted as black against space, which was a lighter blue (in the gaps between stars)

the moon isn't up, so what is this? i live in a village, so it could be low levels of light pollution; is the night sky in non-polluted areas totally black? is it residual sunlight being reflected off the atmosphere; it's around three hours past sundown.

pic not very related, does not suit a hat either.

would suing your university (state public uni) be grounds for them to expel you or do something bad to you? or can they not do that?

(PIC UNRELATED)

How important is GPA for Engineering majors. I've had a 4.0 for my first and second years in EE. However, I've just started my 3rd year which happened to coincide with my first Accutane treatment. I'm really concerned that this stuff may mess with my head and make me not perform as well academically. However I don't seem to have a choice, I don't see why anyone would hire someone who is plagued by constant acne.

Any advice? I'm just kinda venting :(

Write the base-10 equivalent of each of the following two’s complement binary
numbers: (a) 00110011 (b) 11111111 (c) 00000000 (d) 11001100

How exactly do you do something like this? It doesn't say if there is a sign bit or anything.

So I am trying to isolate delta time from this formula:

Delta Displacement = Velocity Initial x Delta Time + 0.5 x acceleration x Delta Time squared.

If you could explain step by step that would help a lot.

Thanks in advance.
