2022河北省唐山市二模篇一：2022唐山二模理科數(shù)學(xué)試題及答案

唐山市2022—2022學(xué)年度高三年級第二次模擬考試

理科數(shù)學(xué)參考答案

一、選擇題：

A卷：CBDADCBADABCB卷：BCDADCBAADCB二、填空題：

201

〔13〕150°；〔14〕；〔15〕20π；〔16〕．

276

三、解答題：〔17〕解：

〔Ⅰ〕因為2accosB＝a2＋c2－b2，所以2(a2－b2)＝a2＋c2－b2＋bc．12π

整理得a2＝b2＋c2＋bc，所以cosA，即A＝

23

ππ

〔Ⅱ〕因為∠DAB＝AD＝BD·sinB，∠DAC＝．

26

在△ACD中，有

ADCDBD＝3CD，sinCsin∠DAC

π3333

所以3sinB＝2sinC，由B＝－C得cosC－sinC＝2sinC，整理得tanC＝

3227〔18〕解：

〔Ⅰ〕證明：

取PD中點E，連AE，EM，那么EM∥AN，且EM＝AN，

四邊形ANME是平行四邊形，MN∥AE．取AD中點O，連PO，那么PO⊥AD．又因為平面PAD⊥平面ABCD，

所以PO⊥平面ABCD，PO⊥CD．〔Ⅱ〕由AB＝AD，AD⊥CD，得□ABCD是正方形，建立如下列圖空間直角坐標系，設(shè)AB＝2，那么

13

A(1，0，0)，B(1，2，0)，D(－1，0，0)，P(0，03)，E，0，．

22

(

)

→DB＝(2，2，0)，→DP＝(1，0，3)，

設(shè)平面PBD的法向量m＝(x，y，z)，那么

22x＋0×y＋3×z＝0，(

)

→|MN·m|2→設(shè)直線MN與平面PBD所成的角為θ，那么sinθ＝|cos7→|MN||m|

〔19〕解：

560(80×200－40×240)2

〔Ⅰ〕K＝5.657，因為5.657＞5.024，

120×440×320×240

所以能在犯錯概率不超過0.025的前提下認為“是否支持節(jié)能降耗技術(shù)改造〞與“企業(yè)規(guī)模〞有關(guān)．〔Ⅱ〕由〔Ⅰ〕可知“支持〞的企業(yè)中，中小企業(yè)家數(shù)之比為1:3，按分層抽樣得到的12家中，中小企業(yè)分別為3家和9家．

設(shè)9家獲得獎勵的企業(yè)中，中小企業(yè)分別為m家和n家，那么〔m，n〕可能為〔0，9〕，〔1，8〕，〔2，7〕，〔3，6〕．與之對應(yīng)，X的可能取值為90，130，170，210．

0918CC1CC27

P(X＝90)＝，P(X＝130)＝，

C12220C12220
