7.在平面直角坐标系xOy中,图形W在坐标轴上的投影长度定义如下:设点P(x1,y1),Q(x2,y2)是图形W上的任意两点.若|x1-x2|的最大值为m,则图形W在x轴上的投影长度l1=M;若|y1-y2|的最大值为n,则图形W在y轴上的投影长度ly=n.如图1,图形W在x轴上的投影长度lx=|3-1|=2;在y轴上的投影长度ly=|...
当点P,Q与点A,C重合时,|x1-x2|的最大值为m=EF,|y1-y2|的最大值为n=GF.图形W的测度面积S=EF•GF,∵∠ABC+∠CBF=90°,∠ABC+∠BAE=90°,∴∠CBF=∠BAE,∵∠AEB=∠BFC=90°,∴△AEB∽△BFC,∴AEBFAEBF=EBFCEBFC=ABBCABBC=4343,设AE=4a,EB=4b,(a>0,b>0),则BF=3a,FC=3b,在RT...
That forwardable ticket can then be used as a /tgs:Y parameter (base64 blob or .kirbi file) to execute the S4U2proxy process. A valid msds-allowedtodelegateto value for the account must be supplied (/msdsspn:X). Say the patsy@testlab.local account looks like this: PS C:\> Get-Do...
【答案】(1)D、F;(2)点K坐标为(1,0)或(0,1);(3)-6≤xN≤-2 【解析】 (1)根据新定义,点A和线段BC的“中立点”是点D、F; (2)点A和⊙G的“中立点”在以点O为圆心、半径为1的圆上运动,因为点K在直线y=-x+1上,设出点K坐标,求解即可; ...

解:(1)根据题意得:y=300-10(x-44)=-10x+740,∴y与x之间的函数关系式为y=-10x+740(44≤x≤52);(2)根据题意得:w=(-10x+740)(x-40)=-10x2+1140x-29600=-10(x-57)2+2890,∵-10<0,∴当x<57时,w随x的增大而增大,∵44≤x≤52,∴当x=52时,w有最大值,最
解:(1)由题意得:y=50+5x,此时70-x>40.∴y与x之间的函数表达式为y=5x+50,0<x<30.(2)由题意,∵利润=(售价-进价)×销售量,∴利润=(70-x-40)(50+5x)=1875.∴解得:x1=15,x2=5.∵为了扩大销售,∴x=15.∴销售单价为70-15=55(元).答:销售单价为55元
