  • Let f(x) = 2kx and g(x) = kx^2, where k is a constant. Is there a value of k >1 such that the averages of f and g are equal on [1, k]?

    I tried writing it out using formula for avg of a function,

    1/k-1 integ(2kx) from 1 to k = 1/k-1 integ(kx^2) from 1 to k

    Expanding, I got 2k^4 - 6k^3 + k = 0.

    I am not allowed to use calculators in my course, and the solutions for k are decimal values that I cannot understand how to get without a calc.

    Or am I doing this wrong and there is no k?

    Thanks

    How do I measure the period of a bifilar pendulum?

    I have a formal lab due, and my idea is to use a bifilar pendulum, model its period using experimental data, and examine the effect of the length of the strings on the amplitude of the period.

    For anyone unfamiliar with it, here is a picture of the pendulum. This is how I plan on setting up my experiment.

    My control variables will be the distance between the strings and the angle the rod is turned to begin the oscillation. I plan on shining a laser at the end of the rod, which will reflect the light back at different angles. If I can measure the amount of time it takes to cross a distance, I can plot a time vs displacement/degrees from equilibrium position. But I'm not sure how I can accurately measure the time. I don't have the budget for expensive gadgets. Is there any way to do this?

    Thanks for any help.

  • Which gaming computer should I get my brother?

    I'm giving him a new one for his birthday. His friend said he needs a lot of RAM because he multitasks, a large screen (his current one is 24 inches). A video card is also important (he has a GTX280) and a fast processor (his current one is a quad processor).

    Note I have no idea what most of these terms mean :')

    Thank you!

  • Ideas for a documentary?

    I'm in the IB program, and as a diploma requirement, we have to do a group-initiated CAS project. CAS stands for Creativity, Action, and Service. Our project must combine two out of those three. My friends and I are planning to do a documentary, about 15-30 minutes long, but we are short on ideas. We could always do the traditional First Nations one, or talking about sex and gender equality, but we want something new and not already overdone. It needs to connect to service to the community, so an idea that would benefit society in some way. Possibly by raising awareness for the issue. Any ideas would be great..Thanks!

  • Why do literary works have strong female characters?

    I am doing a comparison essay on Things Fall Apart and Macbeth. Why do the writers include these strong female characters in a male dominated society? Why couldn't they just write a novel (or play) about the rise and fall of a tragic hero WITHOUT the use of female leads?

  • Things Fall Apart Chapter Six Passage Analysis?

    I need to do a passage analysis (the passage can be no longer than 20 lines) from chapter six in Things Fall Apart, by Chinua Achebe. We need to focus on ONE of the following: character development, theme development, or plot development. The task is to explain why the passage is important to the chapter as a whole, not to summarize the chapter.

    It has to be a concise paragraph with a clear topic sentence.

    I picked out two passages, the one that explains Chielo, and the song at the end of the chapter, which praises Okafo. Are there are other passages that might be better? I keep getting stuck and I don't know what to write.

    Thank you :)

  • What topic should I choose?

    For French we have a project where we have to choose two photos, any pic you can find on the internet, and talk about it for 2-3 minutes. It has to relate to one of the following themes:

    Traditions and history

    Cultural diversity

    Leisures and pastimes

    Medicine and health

    Science and technology

    For my first one, I picked a nuclear reactor, and talked about the pros and cons of nuclear energy. This, obviously, relates to science and technology. I can't think of what my second pic should be. I dont know much about sports, music is my passion, im very science oriented, and i like talking about history. Any ideas? Thank you!!
