lim x-> infinity sqrt(x^2+x)-x) = 1/2

But why? how would you show it mathamatically

How would you antiderrive dy/dx= (4x+1)/(x^2 +1)

Hey guys, i'm a high school student. I have a pretty clear idea of the things i need to do to achieve success in my life, and there are a lot of things i need to get done. But despite constantly thinking about these things, i'm still wasting a lot of time to useless things. Im working really inefficiently, and overall im just pretty lazy. Any tips?

This was a question on my test and i solved it to get pi/8 and other solutions, but no real ones. How would you prove that there are real solutions or is the question just wrong?

When 1.0 mole of Cu3FeS3 and 1.0 mole of O2 are mixed and allowed to react according to the equation

2Cu3FeS3(s) + 7O2(g) → 6Cu(s) + 2FeO(s) + 6SO2(g)

Which would be the reagent in excess, how would you work it out?

What is the x intercepts of y=2-|sqroot(x+1) - 8 |.

My book says its 35 and 99, but i cant seem to get 35

If a quadratic equation is z^2 +pz+q=0, and solutions are 1+i and 4+3i, find complex numbers p and q.

I tried this by subbing (1+i) into z, and i end up with, (2+p)i+p+q=0. I then used null factor law but i get it wrong. Could some one please explai

I have irritable bowel syndrome, but im not quite sure what causes it. Ive recently started to keep a journal of the foods i eat (i eat alot of chinese food since im asian), but i pretty much get bloated everyday regardless, especially during night and during the mornings.

I think it might also be from anxiety, i do feel anxious since sometimes the urgency to go comes up really quickly and randomly. If it is anxiety, what are my options?

thanks guys

If a tugboat weighing 4000tonnes (which is propelled by a thrust of 9.2*10^6N) accelerates to 50km/h, and the friction force is a constant 4*10^6N, how much distance will it travel?

I was told when using the formula W=Fx, to use friction force as F, and let W= the change in kinetic energy. This doesnt really make sense to me, could someone explain?

My maths skills are very basic, i am almost finished high school and i do all the maths subjects. I find maths really interesting, and sometimes i want to purse it as a hobby, especially when i hear about these theory for everything and quantum mechanics and string theory and all these other random stuff. I want to be able to understand some of the maths thats going on behind these things.

How do you guys think i should get there? I know it will take a while but how long would something like this take?

I don't really know much about maths and physics, so it seems strange that the speed of light in a vacuum is in this equation. What does the c have to do with energy and mass?

Stomach cancer in particular, and in the teenage years. If you have family history of it, should you be concerned at a young age?

If someone where to give me a bribe to say, promote them to a position, how would you prove that it was a bribe? Couldn't you say the bribe was a gift of friendship? and that the decision to promote that person was not influenced by the bribe? or is that all the evidence you need?
