2.初二暑假作业练习题答案数学篇二

AADAC x<3 x=“”>3 0,1,2 k<-1 2=“” p=“”>-6 x≥-2 x>2数轴就不画了啊解不等式①得 x<1 1=“” -2=“” x=“”>-2 解集为-2

解：(1)设租36座的车x辆.

据题意得： 36x<42(x-1)

36x>42(x-2)+30

解得： x>7

x<9

∴7

由题意x应取8.

则春游人数为：36×8=288(人).

(2)方案①：租36座车8辆的费用：8×400=3200元;

方案②：租42座车7辆的费用：7×440=3080元;

方案③：因为42×6+36×1=288，

租42座车6辆和36座车1辆的总费用：6×440+1×400=3040元.

所以方案③：租42座车6辆和36座车1辆最省钱.

练习二

CDAAD 1 k<2 3,2,1,0 m≤2 10 解不等式①得 x<-1 解不等式②得 x≥3 ∴无解

解： 2x+y=m①

x+4y=8②

由②×2-①，得7y=16-m，

∴y=16-m/7

∵y是正数，即y>0，

∴16-m/7 >0

解得，m<16;

由①×4-②，得

7x=4m-8，

∵x是正数，即x>0，

∴4m-8>0，

解得，m>2;

综上所述，2

解：(1)设甲、乙两种花木的成本价分别为x元和y元.

由题意得： 2x+3y=1700

3x+y=1500

解得： x=400

y=300

(2)设种植甲种花木为a株，则种植乙种花木为(3a+10)株.

则有： 400a+300(3a+10)≤30000

(760-400)a+(540-300)(3a+10)≥21600

解得：160/9≤a≤270/13

由于a为整数，

∴a可取18或19或20.

所以有三种具体方案：

①种植甲种花木18株，种植乙种花木3a+10=64株;

②种植甲种花木19株，种植乙种花木3a+10=67株;

③种植甲种花木20株，种植乙种花木3a+10=70株.

(1) 1.2(300-x)m 1.54mx 360m+0.34mx

(2) 1.2(300-x)m≥4/5×300m

1.54mx>1/2×300m

解得97又31/77(这是假分数)

∵x为正整数，

∴x可取98，99，100.

∴共有三种调配方案：

①202人生产A种产品，98人生产B种产品;

②201人生产A种产品，99人生产B种产品;

③200人生产A种产品，100人生产B种产品;

∵y=0.34mx+360m，

∴x越大，利润y越大，

∴当x取最大值100，即200人生产A种产品，100人生产B种产品时总利润最大.

练习三

CBBCD y/x-2 2 x>3 7/10 -3/5 m+n/m-n 8/x+2 原式=x+2y/x-2y 代入=3/7

原式=x+3/x 代入=1+根号3

1/a-1/b=3,(b-a)/ab=3

b-a=3ab

a-b=-3ab

2a+3ab-2b)/(a-2ab-b)

=[2(a-b)+3ab]/[(a-b)-2ab]

=(-6ab+3ab)/(-3ab-2ab)

=-3ab/(-5ab)

=3/5

练习四

BAABA -1/5 2/3 1/a 2 1 2/3 x=4 x=2/3 原式=1/a 代入=根号3-1/2

yˉ1+xˉ1y

即求x/y+y/x

=(x2+y2)/xy

=[(x-y)2+2xy]/xy

=11

x2+y2=3xy

(x2+y2)2=(3xy)2

x四次方+y四次方+2x2y2=9x2y2

x四次方+y四次方=7x2y2

原式=x2/y2+y2/x2

=(x四次方+y四次方)/x2y2

=7x2y2/x2y2

(1)设该种纪念品4月份的销售价格为x元.

根据题意得2000/x=(2000+700/0.9x)-20，

解之得x=50，

经检验x=50所得方程的解，

∴该种纪念品4月份的销售价格是50元;

(2)由(1)知4月份销售件数为2000/50=40件，

∴四月份每件盈利800/40=20元，

5月份销售件数为40+20=60件，且每件售价为50×0.9=45，每件比4月份少盈利5元，为15元，所以5月份销售这种纪念品获利60×15=900元.

练习五

BDDBC y=-3/x -3 m<1 y=90/x c

将点A(-1,2-k2)代入y=k/x 得

2-k2=-k

(k+1)(k-2)=0

∵k>0

∴k=2

∴A(-1,-2)

∴y=2/x

将点A(-1，-2)代入y=ax

-2=-a

a=2

∴y=2x

∵y=k/x与y=3/x关于x对称

∴k=-3

∴y=-3/x

将点A(m,3)代入y=-3/x

3=-3/m

m=-1

∴A(-1,3)

将点A(-1,3)代入y=ax+2

-a+2=3

-a=1

a=-1

(1)将点A(1，3)代入y2=k/x

3=k/1

k=3

∴y=3/x

将点B(-3，a)代入y=3/x

a=3/-3

a=-1

∴B(-3,-1)

将点A(1,3)和B(-3，-1)代入

m+n=3

-3m+n=-1

解之得 m=1 n=2

∴y=x+2

A．势能减少，动能增加，机械能不变B．势能减少，动能不变，机械能减少 C．势能不变，动能不变，机械能不变D．势能减少，动能不变，机械能不变 3.关于机械能的论述，下列说法正确的是（）

A．在空中飞行的飞机只具有动能B．炮弹具有的机械能一定比子弹具有的机械能大

C．质量和速度都相同的物体具有的动能一样大D．质量大的物体的具有的重力势能一定大 4.关于机械效率的说法正确的是（）

A．越省力的机械，其机械效率越高B．做的总功越多，机械效率越高

C．做的有用功越多，机械效率越高D．有用功一定时，额外功越少，机械效率越高

5.甲、乙两辆汽车，功率之比为2∶1，在相同时间内沿水平路面通过的距离之比为1∶2．则它们所做的功之比为（）

A．2∶1 B．1∶1 C．1∶4 D．4∶1 6.下列单位中不是功的单位的是（）

A．W·s B．J C．J/s D．N·m 7.某人用手将一物体竖直举高2m和用机械效率为80％的斜面将它升高2 m．比较两种情况（）

A．用手举高时做功多B．用斜面升高时做功多 C．两种情况做功一样多D．两种情况都不做功

8.跳水运动员从最高点向水面下落的过程中，他的________能逐渐减少，________能逐渐增加． 9.一只小鸟在空中飞行时具有40J的机械能，若它具有10J的势能，则它具有________J的动能． 10.小明在水平面上用50 N的水平推力，加速推着一辆重120 N的小车，前进了10 m，小明的推力做功是________J．水平面对小车的支持力做功是________J．

11.甲、乙两辆汽车在公路上匀速行驶．如果它们的功率相同，行驶速度之比v甲∶v乙＝2∶1．在相同的时间内，甲、乙两车牵引力做功之比为________．

12.用一只铁桶从深井中取水，第一次取半桶，第二次取满桶，两次相比：W1额_____W2额，η1___η2（填“＞”“＜”或“＝”）

二、计算题（每小题5分，共10分）

13.一人用如图所示．的滑轮组匀速提升物重为200牛的物体，此时人对绳的拉力为120牛，不计绳重和摩擦．求： 1）滑轮组的机械效率． 2）如果人的体重为600牛，那么他们用此滑轮组所提升物体的物重不能超过多少牛？ 1）滑轮组的机械效率等于有用功除以总功，有用功等于物体的重力乘以物体上升的高度，总功等于拉力乘以绳子自由端移动的距离．

2）当绳子的拉力和人的体重相等时，滑轮组所提升物体的物重最大，先计算出动滑轮的重力，最大拉力就等于最大物重与动滑轮重和的一半．从而求出最大物重．

功和机械能参考答案1．B 2．B 3．C 4．D 5．A 6．C 7．B 8．势动 9．30 10．500 0 11．1∶1 12．＝＜

13.解答：解：（1）η=Gh2Fh=200N2×120N=83.3% 答；滑轮组的机械效率为83.3%．

（2）设动滑轮重G0，由2F=G+G0，得G0=40牛

设提升的最大物重为G′，人的体重为G1，此时绳的拉力为F′，则F′=G1，由2F′=G′+G0，得所能提起物体的最大物重

G′=2F′-G0=2×600N-40N=1160N．
