  1. I would say that the answer is clearly "10". As far as an explanation is concerned my first thought would be to note that the numbers in the left column are decreasing by "1" each time, that 54 is 9 times 6, that 40 is 8 times 5, and that 28 is 7 times 4 so following that pattern, the "next row" would have 3 on the left, and 6 times 3= 18 but that row is missing so the next row has "2" on the left and then 2 times 5= 10. But you don't like that explanation because, for some reason, you don't like the appeal to a "missing row", So, instead, I would say that each number on the left is decreasing by "`1" until we get to the last, "2", which is 2 less than 4. I would also note that each number on the right is the number on the left multiplied by 9, 8, 7, also decreasing by 1. but since for the last step the left number decreased by 2, I would also decrease the multiplier by 2 to 7- 2= 5 and so the number on the right is 2*5= 10. 这是相同的解释,但不影响“缺失行”。
  2. 我会说分子永远不会“蒸发”。当分子离开水体时,蒸发的是水体。当然,当您将水加热到沸点时,气泡会出现在水中。您是否想将其视为“蒸发”?
  3. 我一直以为这就是所谓的“薛定inger之猫”的意思,即量子作用(一个射出亚原子粒子的原子核)会产生宏观后果,猫死或活着。对于人体或任何大量的量子物体,量子效应将趋于平均。
  4. 我突然开始感到不规律。
  5. " In what sense are functions curves? I think you are talking about the graphs of functions. Do you know the definition of "function"? It follows immediately from that definition that the graph of any function, elementary or not, is a simple curve. In fact, the graph of $x^2+ y^2= 1$ is a circle, so a "simple curve" even though y is not a function of x nor is x a function of y.
  6. 我不知道你从哪里得到这个主意的!上一个冰河时代,即“地球上大部分地区都被冰覆盖的时代”结束了大约3,000,000年前(也许您刚刚丢下了“ 000”)。有一个时期,有时被称为“小冰期”,其温度低于正常温度,但没有冰盖,直到200年前才结束(这就是为什么“华盛顿穿越特拉华州”这幅画在河中结冰的原因)。
  7. 那我怎么搬到那儿呢?

    题?

    It's hard to believe you are serious! From your other posts I had thought that you were past third or fourth grade arithmetic- which is basically what this is. I would hope that you know that 1x1= 1, 2x1= 2, and 1- 1= 0. And if 1- ?= ? the, adding "?" to both sides 1= 2?. What number, multiplied by 2, gives1?
  9. “大量生物”?今天的蓝鲸比恐龙大得多!
  10. 这不是“一致性”的含义。说Peano公理是一致的,这意味着Peano公理不能用来证明陈述“ p”和“ not p”。说Peano公理不能用来证明其自身的一致性,就意味着该公理不能用来证明该陈述。
  11. 这与这里的要点并不真正相关,但是大多数人不会因为“事件”而死亡。他们死是因为他们的身体磨损了。那将在任何宇宙中发生。
  12. If I remember correctly, a region in $R^2$ is "regular" if its boundary is a simple closed curve. (And a curve is "simple" if it does not cross itself.) Yes, the rectangular region $a\le x\le b$, $c\le y \le d$ is a "regular region". As to the integral, $\int_{u(x)}^{v(x)} f(x,y)dy$, Assuming that f is an "integrable" function of y, then $\int_{u(x)}^{v(x)} f(x,y)dy$ is a function of x, F(x). I might think of the "x" as a "parameter" in the integral but as a variable in f(x,y) and in F(x).
  13. “建筑师”唯一可以肯定地表明的是他不是数学家! (而且我很希望他也不是建筑师-我讨厌不得不住在他设计的高层或建筑物中。)
  14. 您了解这主要是阅读理解练习吗? (这是编程或软件工程中极其重要的技能)。几乎没有数学或程序设计。
  15. 这与我所说的有什么矛盾?生活在救济金中的人仍然需要金钱-活着并不是令人满意的生活!
