  • Pimple on pubic area?

    Is this normal? How do I get rid of it? I'm a virgin so the idea that it's an STI or an STD is off the list as far as I know.

    Does anyone have any solutions for this? It doesn't really bother me that much but it's strange and it doesn't seem to be like warts or anything. Though I've had a wart before on my neck, close to my ear. I don't think it's the same thing though. I'm fairly sure it's just a pimple- what do you think?

    It feels like a pimple and is sorta pink but not really. (I can't really see the color correctly since I have a lot of hair down there...) Sorry for all the details.

  • AB Calculus problems help?

    Let f be a function that is differentiable on the

    open interval (1,10). If f(2) = −5, f(5) = 5,

    and f(9) = −5, which of the following must

    be true?

    I) f has at least 2 zeros.

    II) The graph of f has at least one horizontal tangent.

    III) For some c, 2 < c < 5, f(c) = 3

    ______________________________________…

    pot fall before it is too late for a warning

    shouted from the balcony to reach the man in

    time? Assume that the man below requires

    0.313 s to respond to the warning, and the
