说 明:本卷共七大题,全卷共24题,满分120分,考试时间为100分钟.

一、选择题(本大题共6小题,每小题3分,共18分)

1. 4的平方根是 ( )

A.2 B.4 C.±2 D.±4

考点:平方根

分析:根据平方根的定义,求数a的平方根,也就是求一个数x,使得x2=a,则x就是a的平方根,由此即可解决问题

解答:解:∵(±2)2=4

∴4的平方根是:±2.

故选C.

点评:本题考查了平方根的定义.注意一个正数有两个平方根,它们互为相反数;0的平方根是0;负数没有平方根

2.如图是一次函数的图象,则它的解析式最有可能是( )

A.y

3x 23C.yx2 22x 32D.y1x 3B.y

考点:一次函数图象与系数的关系

分析:该函数图象经过第二、四象限,所以一次函数y=kx+b(k≠0)中的k<0;直线与y轴交于正半轴,则b>0

解答:解:如图,该直线经过第一、二、四象限.

A、该直线经过第一、三象限.故A选项错误;

B、该直线经过第二、四象限,故B选项错误;

C、该直线经过第一、二、三象限,故C选项错误;

D、该直线经过第一、二、四象限,故D选项正确;

故选:D.

点评:本题主要考查一次函数图象在坐标平面内的位置与k、b的关系.解答本题注意理解:直线y=kx+b所在的位置与k、b的符号有直接的关系.k>0时,直线必经过一、三象限.k<0时,直线必经过二、四象限.b>0时,直线与y轴正半轴相交.b=0时,直线过原点;b<0时,直线与y轴负半轴相交

3.在一次“爱心互助”捐款活动中,某班第一小组7名同学捐款的金额(单位:元)分别为:6,3,6,5,5,6,9.这组数据的中位数和众数分别是( )

A.5,5 B.6,5 C.6,6 D.5,6

考点:众数;中位数.

分析:找中位数要把数据按从小到大的顺序排列,位于最中间的一个数(或两个数的平均数)为中位数;众数是一组数据中出现次数最多的数据,注意众数可以不只一个.

解答:解:从小到大排列此数据为:3,5,5,6,6,6,9.数据6出现了三次最多,为众数;第4位是6,为中位数.∴本题这组数据的中位数是6,众数是6.

故选C.

点评:本题属于基础题,考查了确定一组数据的中位数和众数的能力.一些学生往往对这个概念掌握不清楚,计算方法不明确而误选其它选项.注意找中位数的时候一定要先排好顺序,然后再根据奇数和偶数个来确定中位数,如果数据有奇数个,则正中间的数字即为所求.如果是偶数个则找中间两位数的平均数.

4.已知三角形相邻两边长分别为20cm 和13cm.第三边上的高为12cm,则第三边长( )

A.19cm B.19cm或9 cm C.21cm D. 21cm或11cm

考点:勾股定理.

专题:分类讨论.

分析:此题考虑两种情况:①第三边上的高在三角形内部;②第三边上的高在三角形外部,分别利用勾股定理结合图形进行计算即可.

解答:解:①第三边上的高在三角形内部;

如图1所示,AB=20cm,AC=13cm,AD=12cm,

∵AD是高,

∴△ABD、△ACD是直角三角形,

∴BD=

同理CD===5cm, =16cm,

∴BC=BD+CD=16+5=21cm;

②第三边上的高在三角形外部;

如图2所示,AB=20cm,AC=13cm,AD=12cm,

∵AD是高,

∴△ABD、△ACD是直角三角形,

∴BD=

==16cm,

同理可求CD=5cm,

∴BC=BD﹣CD=16﹣5=11cm.

故选D.

点评:本题考查的是勾股定理,在解答此题时要注意分两种情况进行讨论,不要漏解.

5.如图AB=AC,则数轴上点C所表示的数为( )

A.+1 C.-+1

B.-1 D.--1

考点:勾股定理;实数与数轴.

分析:根据勾股定理列式求出AB的长,即为AC的长,再根据数轴上的点的表示解答. 解答:解:由勾股定理得,AB==,

∴AC=,

∵点A表示的数是﹣1,

∴点C表示的数是﹣1.

故选B.

点评:本题考查了勾股定理,实数与数轴,是基础题,熟记定理并求出AB的长是解题的关键.

6.小刚去距县城28千米的旅游点游玩,先乘车,后步行.全程共用了1小时,已知汽车速度为每小时36千米,步行的速度每小时4千米,则小刚乘车路程和步行路程分别是( )

A.26千米, 2千米

C.25千米, 3千米 B.27千米, 1千米 D.24千米, 4千米

分析:设小刚乘车路程为x千米,步行路程y千米,根据题意可得等量关系:①步行路程+乘车路程=28千米;②汽车行驶x千米时间+步行y千米的时间=1小时,根据题意列出方程组即可.

解答:解:设小刚乘车路程为x千米,步行路程y千米,由题意得:

, 解得:.

故选:B.

点评:此题主要考查了二元一次方程组的应用,关键是正确理解题意,找出题目中的等量关系. 二、填空题(本大题共8小题,每小题3分,共24分)

7. 计算:-2

考点:二次根式的加减法.

分析:运用二次根式的加减法运算的顺序,先将二次根式化成最简二次根式,再合并同类二次根式即可.

解答:解:原式=2﹣=.

故答案为:.

点评:合并同类二次根式实际是把同类二次根式的系数相加,而根指数与被开方数都不变. 8 .已知点A(l,-2),若A、B两点关于x轴对称,则B点的坐标为_______

考点:关于x轴、y轴对称的点的坐标.

专题:计算题.

分析:平面直角坐标系中任意一点P(x,y),关于x轴的对称点的坐标是(x,﹣y),记忆方法是结合平面直角坐标系的图形记忆,另一种记忆方法是记住:关于横轴的对称点,横坐标不变,纵坐标变成相反数.

解答:解:∵A、B两点关于x轴对称,

∴点B的坐标是(1,2).

故答案为(1,2).

点评:本题比较容易,考查平面直角坐标系关于坐标轴成轴对称的两点的坐标之间的关系.是需要识记的内容.

9. 若a<1,化简(a1)21是考点:二次根式的性质与化简.

分析:

而得到原式的值.

解答:解:∵a<1,

∴a﹣1<0,

=﹣(a﹣1)﹣1

=﹣a+1﹣1

=﹣a.

【数学八年级上全册单元测试卷(含答案)新目标】

故答案为:﹣a. =|a﹣1|﹣1,根据a的范围,a﹣1<0,所以|a﹣1|=﹣(a﹣1),进=|a﹣1|﹣1

点评:本题考查了二次根式的性质与化简,对于

再去绝对值符号,即.: 化简,应先将其转化为绝对值形式,

10.某校八年级(1)班共有男生30名,女生20名,若测得全班平均身高为1.56米,其中男生平均身高为1.6米,则女生平均身高为 米.

考点:加权平均数.

分析:根据平均数的公式求解即可.用50名身高的总和减去30名男生身高的和除以20即可.

解答:解:某班共有50名学生,其中

30名男生,20名女生,平均身高为1.56m; 设女生的平均身高为x米,依题意有:

=1.56,

解得x=1.5.

故答案为:1.5.

点评:本题考查的是样本平均数的求法及运用,解题的关键是牢记平均数的计算公式.

11.若一次函数y2x6与ykx图象的交点到x轴的距离为2,则k的值为. 考点:两条直线相交或平行问题.

分析:首先根据一次函数y=2x+6与y=kx图象的交点到x轴的距离为2,得到两直线的交点的纵坐标为2或﹣2,代入一次函数求得交点坐标为(﹣2,2)或(﹣4,﹣2),然后代入y=kx求得k值即可.

解答:解:∵一次函数y=2x+6与y=kx图象的交点到x轴的距离为2,

∴两直线的交点的纵坐标为2或﹣2,

∴2=2x+6或﹣2=2x+6,

解得:x=﹣2或,x=﹣4,

∴交点坐标为(﹣2,2)或(﹣4,﹣2),

代入y=kx得k=﹣1或,

故答案为:﹣1或.

点评:本题考查了两条直线平行或相交问题,解题的关键是能够分类讨论.

12. 若关于x,y的方程组2xymx2的解是,则|mn|= . xmyny1

考点:二元一次方程组的解.

分析:所谓“方程组”的解,指的是该数值满足方程组中的每一方程的值,只需将方程的解代入方程组,就可得到关于m,n的二元一次方程组,解得m,n的值,即可求|m﹣n|的值. 解答:解:根据定义把

, ∴, 代入方程,得

∴|m﹣n|=2.

故答案为2.

点评:此题主要考查了二元一次方程组解的定义.以及解二元一次方程组的基本方法.

13.将一张等宽的直条型纸片按图中方式折叠,若∠1 = 50°,

则∠2的度数为考点:平行线的性质;翻折变换(折叠问题).

专题:推理填空题.

分析:由已知∠1=50°,可得,∠3=50°,那么∠4=(180°﹣∠3)÷2=65°,所以∠2=180°﹣∠3﹣∠4.求出∠2.

解答:

解:由已知矩型纸片和平行线的性质及折叠原理得:

∠3=∠1=50°,

∴∠4=(180°﹣∠3)÷2=65°,

∴∠2=180°﹣∠3﹣∠4=180°﹣50°﹣65°=65°.

故答案为:65°.

点评:此题考查的知识点是平行线的性质和翻转变换问题,解题的关键是由平行线的性质先求出∠3,再由折叠原求出∠4.从而求出∠2.

14.在平面直角坐标系中, 已知点 A

, 0) , B

, 0) ,

点C在x轴上, 且AC+BC = 6, 写出满足条件的所有点C的坐标.
