    庾佩14789368007: 喷瓜是葫芦科的一种植物,其性别决定由基因决定.决定性别的是三个等位基因,即aD、a+、ad;其显隐关系为aD对a+为显性,a+对ad为显性.aD基因决定发... -
    45993宰才 :[答案] (1)aD对a+、ad为显性,a+对ad为显性,则当aD存在时植株表现为雄性,当基因型为adad时植株表现为雌性,当基因型为a+a+、a+ad时植株表现为雌雄同株,如果雄性植株为纯合体,则它的基因型即为aDaD,这需要此植株的父本和母本各提供一...

    庾佩14789368007: 在三角形ABC中,AB=2,AC=3,D是BC的中点,则向量AD乘以向量BC=? -
    45993宰才 :[答案] =2.5首先建立直角坐标系以A为原点AC设在x轴上,则B轨迹为以A为原点半径为2的圆方程为x2+y2=4.设B为(a,b)则B满足方程.此时D的坐标为{(3+a)/2,b/2},向量AD同D坐标,向量BC为(3-a,-b).向量AD乘BC为(3+a)*(3-a)/...

    庾佩14789368007: (2014•盘锦三模)如图,▱ABCD的周长为16cm,AC、BD交于点O,且AD>CD,过O作OM⊥AC,交AD于点M,则△CDM的周长为______cm. -
    45993宰才 :[答案] ∵四边形ABCD是平行四边形, ∴OA=OC, ∵OM⊥AC, ∴AM=CM, ∴△CDM的周长为:CD+DM+CM=CD+DM+AM=CD+AD, ∵▱ABCD的周长为16cm, ∴CD+AD=8cm, ∴△CDM的周长为8cm. 故答案为:8.

    庾佩14789368007: 如图在三角形abc中角c90度角b45度ab平分角bac且交bc于点d求证ab=ac+cd -
    45993宰才 :[答案] 证明:过D作DE⊥AB于E, ∵AD平分∠BAC,∴∠DAC=∠DAE, ∵∠AED=∠C=90°,AD=AD, ∴ΔADC≌ΔADE(AAS), ∴AE=AC,CD=DE, ∵ ΔABC是等腰直角三角形,∴∠B=45°, ∴ΔBDE是等腰直角三角形, ∴DE=BE, ∴AB=AE+BE=AC+CD.

    庾佩14789368007: 正方形abcd,ab边上有一点e,ae=3,eb=1在ac上有点p使ep+bp为最短ep+bp为?ac为abcd对角线,p图上没有. -
    45993宰才 :[答案] 连接BD交AB于P,则P为所求(即PE+PB最小). 连接DE,AB=AE+BE=4, ∵ABCD是正方形,∴∠DAE=90°,AD=AB=4, ∴DE=√(AE²+AD²)=5, ∴PE+PB最小=5.

    庾佩14789368007: 如图,三角形ABC中∠B=60°AD,CE分别是∠BAC,∠ACB的角平分线.E点在AB上,D点在BC上在.求证AE+CD=AC. -
    45993宰才 :[答案] ∵∠ABC=60° ∴∠BAC+∠BCA=120° ∵AD、CE是∠BAC、∠BCA的角平分线 ∴∠OAC+∠OCA=60° ∴∠AOC=120° ∴∠AOE=∠COD=60°(对顶角,圆周角=360°) 作∠AOC的角平分线OM交AC于M 则∠AOE=∠AOM=60°∠COM=...

    庾佩14789368007: 在三角形ABC中 角B=40度,BD平分角B交AC于点D,且BD+AD=BC,求证AB=AC -
    45993宰才 :[答案] 证明: 在BC上截取BE=BD,连接DE ∵BD+AD=BC BE+CE=BC ∴AD=CE ∵BD平分∠ABC ∴AB:BC=AD:CD ∴AB:BC=CE:CD 又∵∠ACB=∠ECD【公共角】 ∴⊿ACB∽⊿ECD【对应边成比例夹角相等】 ∴∠A=∠DEC ∵∠B=40º ∴∠DBE...
