T T想说你是不是钱的符号带错了 怎么又是英镑又是欧元又是便士的..欧元怎么化便士
欧元可以转成英镑，英镑换算成便士，但是我也各种乱 不会做

a tangent line to the eclipse x^2+4y^2=5 has an x-intercept of -5 and passes through the point Q(3,k) in the first quadrant.Determine the value of k
答：与椭圆x²+4y²=5相切的直线在x轴上的截距为-5并且经过点（3,k）,试求k值设直线为y=a(x+5),在x轴上的截距为-5代入椭圆方程得：x²+4a²(x²+10x+25)=5整理得：(4a²+1)x²+40a²x+100a²-5=0直线与椭圆仅有一个交点为切点,上述方程有唯一的解判别式=(40a²)²-4(4a²+1)(100a²-5)=0所以：0a^4+80a²-400a²+20=0所以：320a²=20解得：a²=1/16所以：a=1/4或者a=-1/4直线为y=(x+5)/4或者y=-(x+5)/4x=3代入得：y=k=2或者-2所以：k=2或者k=-2

gave a math test that had 30 questions worth 1 point apiece.Mrs.Thompson
dosen't give any partial credit on questions, and when she scored the test, she found her students got an average of 89%, with a standard deviation of 4%.If katherine scored inside of 3 standard deviations for
the test, how many possible percent scores could katherine have had?A.5
汤普森女士出了一份数学试卷,有30个问题每题1分.答对部分是不能给分的（也就是说每题要么1分,要么0分）.当她批改的时候发现她的学生们的平均答对比例是89%,标准差是4%.那么如果学生凯瑟琳的得分是在3%的标准差之内的,那么她的可能的得分比例有几个?这题应该选D 8个如果凯瑟琳的得分是在3%的标准差之内的 那么她的得分比例就应该在77% 101%之间,其实是77~100%,因为不可能超过100%.所以全打对就是100%,对29题就是97%,对28题是94%,依次下来最后到对23题,79%,一共有8个可能答案.
汤姆森女士给学生数学测试，30道题，每题一分。她并没有给任何一道题特定的权重，当统计大家的分数时，她发现学生得到了一个89%的正确百分比，标准方差是4%。如果凯瑟琳得到了3个标准方差之内的分数，问有多少种她得到的百分比的可能数量？这道题标准方差是4
用89%乘以方差4% 得到3.56% 这时候必须约掉多余的小数后位 因为她的百分比只能是整数 之后再乘以3个标准方差 就是9种整数可能...

本题有三个小问Use the following to answer questions 1-3 Rex and Kaven just graduated from college and got jobs.Assume Rex and Kaven will each live for 2 more years,and that they will each need to purchase a car in year 1 to last them for both years.Rex believes that the price of gasoline will only increase by 5% between year 1 and year 2.Kaven believes that supply constraints will drive the price of gasoline up by 40% between year 1 and year 2.Rex must commute 10 miles round trip to work each day,and Kaven must commute 5.Assume there are 260 working days each year.There are 2 cars on the market to choose from.The ‘F5000’ gets 10 miles per gallon and costs $20,000.The ‘Envy’ gets 45 miles per gallon and costs $21,500.The interest rate is 10%.1.What is the lowest price per gallon of gasoline in period 1 such that Kaven will purchase an ‘Envy’?(Rounded to the nearest cent) A.$2.15 B.$6.53 C.$3.80 D.$23.22 E.None of the above 2.What is the lowest period 1 gas price such that Rex will purchase an ‘Envy’?A.$2.15 B.$6.53 C.$3.80 D.$23.22 E.None of the above 3.If the national economy goes into a recession,and the Federal Reserve decreases interest rates to spur investment.Assuming gas prices remain unchaned,what effect will this have on Rex and Kaven’s car decisions?A.They will be more likely to purchase an ‘F5000’.B.They will be more likely to purchase an ‘Envy’.C.The interest rate change is not important to their decision.D.The interest rate will not change Rex’s Decision if gas is $7 a gallon.E.None of the above
Rex 和Kaven刚刚从大学毕业找到工作.假定他们两人都能再多活两年,他们俩在第一年都要买一辆车并且这辆车能用到他们去世.Rex认为第一年到第二年汽油的价格仅会增长5%.Kaven则认为随着汽油供应的限制,第一年到第二年汽油价格会增长40%.Rex每天要走10英里去工作的地方而Kaven要走5英里.假设他们每年有260天的工作日.市场上有两辆车供他们选择.“F5000"这款车一加仑的油可以走10英里,花费20000美元.“envy”这款车一加仑可以走45英里,花费21500美元.利率为10%.问题1：在第一阶段一加仑汽油的最低价格是多少才能使Kaven买'envy'这款车?（数字就不翻译了,最后一个选项“上面的答案都不对”）问题2：在第一阶段一加仑汽油的最低价格是多少才能Rex 买'envy'这款车?(同上）问题3：如果国民经济呈现衰退趋势,美联储（美国的中央银行）降低利率来刺激投资.假设汽油价格不变,这项举措将会对Rex和Kaven 买车的决定产生什么影响?A.他们更可能买一辆“F5000"B.他们更可能买一辆‘Envy’.C.利率的降低对他们的决定没有影响D.如果汽油价格是一加仑7美元,利率的降低不会改变Rex的决定E.以上答案都不对PS:不好意思楼主,我只能帮你到这儿了.加油算吧 理解不明白的再问我.
