  1. 你題目翻譯的怪怪的,應該是: 給定函數f(x)=x^5+3x^3+2x+1,且f(x)有一個反函數g(x),請計算g'(x)=? 2006-11-13 23:55:05 補充: 最後打錯字了,應該是「請計算g'(7)=? 」 2006-11-14 00:27:02 補充: 因為g是f的反函數,也就是如果f(x)=y,則g(y...

  2. 1. y=3x, x increase by 5%: 等號兩端同時乘以1.05 1.05y= 3(1.05x) 1.05y-y=0.05y(增加量) 0.05y / y = 0.05= 5%(增加率) Ans: 5% 2. y=5x*,*=3 所以y=5x^3 x decrease by 20%: 5(x-20%x)^3=5(4/5x) ^3=5╳(64/125) x^3=(64/25)x^3 (64/25)x^3 / 5x^3= 64/125 所以 (64/125)y=(64/25)x^3 y-(64/125)y= (61/125)y(減少量) (61/125)y/ y =61/125=48.8%(減少率...

  3. 五個pump,每個故障機率0.15,超過三個故障系統會停擺,求故障機率 因此方便計算三個、四個、五個的機率 三個 5C3 * (0.15)^3 * (0.85)^2 =0.024384 四個 5C4 * (0.15)^4 * (0.85)^1=0.002152 五個 5C5 * 0.15^5 = 0.000076 將上述三個相加可得機率 0.026612

  4. 翻譯: 蒜素這個化合物是造成大蒜會有特殊氣味的原因 下列有一個分析顯示這個化合物的重量組成 炭占了總重的百分之四十四點四 氫占了總重的百分之六點二一 硫占了總重的百分之三十九點五 氧占了總重的百分之九點八六 計算它的實驗式 當它的莫耳質量約是162克時,它的分子式...

  10. 1.-2-(-2)/-2-(-8)=0/6=0所以斜率為0 2.y-(-3)=0*(x-4)+c y=-3+c 3.因資料不足請補充 (翻譯:下列哪一條線不平行於 y = -3x +3) 2008-08-23 03:58:22 補充: 2.且通過(4.-3)帶入原來等式 得到C=0,因此Y=-3 3.原式斜率為 -3 A.斜率為 -3 B.斜率為 3 C.斜率為 -3...
