    Best answer: Please try posting again. Your monolithic ramble got cut off by the character limit. I do have a few suggestions, though: (1) Learn English. I suspect that very few people will read through the horrid level of errors you've posted above. When you try again, get someone competent in the language to read through your material for grammar and composition. (2) You are not in love; you are infatuated. Infatuation is a good beginning for a fuller relationship, but please don't mistake it for something more lasting. You've already made a couple of highly questionable decisions based on this misinterpretation. The strongest evidence of this is how you admit that you've been cheated, but you're still holding to your inner fantasy of this guy. (3) Post clearly. State the your needs clearly and succinctly at the outset. Summarize the problem.

  • Whats the derivative of y=sqtr x using first principle?

    Best answer: Your previous responder failed to use the first principle. f(x) = √x f'(x) = [lim h-> 0] (f(x+h) - f(x)) / h Substitute the functional definition: f'(x) = [lim h-> 0] (√(x+h) - √x) / h Since you gave no hint of where you're stuck, I have to assume that it was at the beginning. I hope that you can finish from here. show more

  • How should I plot these two sets of values on a graph (physics, oscillating experiment)?

    Best answer: k is the decay constant; it's a measure of how quickly the amplitude decays. n is time, for all practical purposes, with n=1 denoting a full swing (from initial point to both sides and back). On the graph, you plot "n" as the ordinal (horizontal) value and "A" as the abscissa (vertical) value. You're... show more
    Best answer: k is the decay constant; it's a measure of how quickly the amplitude decays. n is time, for all practical purposes, with n=1 denoting a full swing (from initial point to both sides and back). On the graph, you plot "n" as the ordinal (horizontal) value and "A" as the abscissa (vertical) value. You're experimentally finding the value of k. For instance, measure the value of A[10], which is after 10 full swings. The decay ratio is A[10] / A[0]. e^(-k) is the 10th root of that ratio.

    Best answer: Part A 0.134 moles of NaN3 is 2 units in the given equation's left side. This will produce 3 units of N2 gas. If 2 units = 0.134 moles, then 3 units = 3/2 * 0.134 moles = 0.201 moles. What is the volume of 0.201 moles of a gas at STP? What is its volume at the same pressure, but a temperature of 300C (573 K, rather than 273 K)? That's 573/273 of the previous volume. Part B Given the volume you just computed, how many "units" of NaN3 do you need to produce 2.51L of gas? What is the molecular weight of NaN3 (sodium + 3*nitrogen)? Mulitply; there's your answer. Part C Let "b" be the mass you found in part B. This one is a simple proportion: you know that "b" grams produces 2.51 L of gas. How many grams will produce 1.00/1.057 L ? Set up the proportion and solve. Got it?

    Best answer: Tim, you've posted four problems in this set, without managing to do even the first step of any of them yourself. You need to see your teacher about a little extra help on this section; you're not getting something, somewhere, that's critical to your success in the class. That said, this one is easy, since it's a single inequality (the others are two inequalities). Just like any other single inequality, you graph it as if it were an equality: x^2 - 7x + 10 = 0 You already know how to factor this to get the zeroes; getting the y-intercept is trivial, and you know how to find the vertex. That lets you draw the graph pretty easily. Since it's a strict inequality, use a dashed curve. All that's left is to figure out whether to shade the inside or the outside of the curve. There are two simple ways: (1) Experimental: choose one point that's not on the dashed line. (0,0) is usually really easy. If that gives you a true statement in the inequality, then shade that side of the curve; otherwise, shade the other side. (2) Analytical: Think of this as y = x^2 - 7x + 10 y > 0 Now ... which side do you shade if the y-value has to be *more* than the values on the curve? Think of drawing a lot of little vertical lines, each starting on one point of the curve, and shooting to infinity in the y-positive direction. Do those get you going for this and similar problems?

    Best answer: You'll get better responses if you move this to the proper group. This belongs in Singles & Dating, not Homework Help. That said, keep in mind that this is a permanent, semi-public record. This is roughly equivalent to standing up in your last class at school and telling her how you feel in front of 25 other students. What can you say that will be sufficiently personal for you, but won't embarrass either of you, now or later? Remember, she'll have to explain this to her children in 20 years. ----------------------- As for specific words ... well, it's pretty hard to help you out, because you've told us *nothing* about the state of your relationship with her. Does she like you? Does she know you like her? How does she feel about you? Most of all, anything unstable, uncertain, or potentially embarrassing should be handled face to face, not in the yearbook. If you have a solid understanding between the two of you, then feel free to leave her a representative piece of your heart on that page. If not, then drop back to something less definite, such as "Your presence makes every school day easier to navigate; I'll really miss you over the summer." Then handle the rest in private. However, the best solution is likely to talk to her ASAP. Tell her how you feel, let her know that you're conflicted about what to write in her book. Get things settled between the two of you, and then ask what sort of inscription she'd like to remember you. That gives her a framework of input, but lets you work within any boundaries she might care to set. Will that work for you?

Depending on where you live, you might want to choose a colony with a similar history. For instance, if you live in the South or Southwest, you might find that the Carolinas somewhat easier. Also, do consider Pennsylvania and New York. After all, Philadelphia and New York City had enough influence to be our first capital cities. New york began as a Netherlander colony, while Pennsylvania (founded by William Penn) also gave us Benjamin Franklin and quite a few other critical figures from that period, and rivaled Virgina for influence in the early days.

    Best answer: Different guys, different likes. Also, it depends a lot on how comfortable you are with yourself. One of my fondest memories is of a lady who was decidedly overweight, but quite comfortable and upbeat, and willing to let me be her friend on short notice and a strong recommendation. My strong involvements have ranged from 5' zilch to a hair over six feet, and from what I *did* consider too thin to the aforementioned "large squeeze". If she's pretty on the inside, great -- pretty on the outside is a nice bonus, but I'll give that up for the girl who laughs with me and makes my mind sing.
