新思维初中数学试卷答案

一、选择题（每题4分，共20分）1. 下列各数中，有理数是（）A. √2B. πC. 3.14D. 0.1010010001…答案：C解析：有理数是可以表示为两个整数之比的数，其中分母不为零。

3.14是π的一个近似值，但π是无理数，所以A、B选项错误。

0.1010010001…是一个无限不循环小数，也是无理数，所以D选项错误。

C选项3.14是一个有限小数，是有理数。

2. 如果a+b=5，ab=6，那么a²+b²的值是（）A. 19B. 25C. 36D. 49答案：A解析：由平方差公式得，a²+b²=(a+b)²-2ab。

代入a+b=5和ab=6，得a²+b²=5²-2×6=25-12=19。

3. 下列函数中，是反比例函数的是（）A. y=x²B. y=2xC. y=3/xD. y=2x+1答案：C解析：反比例函数的定义是y=k/x（k为常数，且k≠0）。

只有C选项符合这个定义。

4. 在直角坐标系中，点A（-2，3）关于x轴的对称点是（）A.（-2，-3）B.（2，3）C.（2，-3）D.（-2，3）答案：A解析：关于x轴对称的点，横坐标不变，纵坐标取相反数。

所以点A（-2，3）关于x轴的对称点是（-2，-3）。

5. 一个等腰三角形的底边长为10cm，腰长为8cm，那么这个三角形的面积是（）A. 32cm²B. 40cm²C. 48cm²D. 64cm²答案：C解析：等腰三角形的面积公式是S=1/2×底×高。

底边长为10cm，腰长为8cm，那么高可以通过勾股定理计算得到：高²=腰²-（底/2）²=8²-(10/2)²=64-25=39，所以高=√39。

代入公式得S=1/2×10×√39=5√39≈48cm²。
