answer the whole of this question on a piece of graph paper.
the coordinates of the point A,B,C are (1,2),(2,2),(3,0)respectively.given that the triangle ABC is mapped onto triangle XYZ by means of an enlargement with center at origin an scale factor 2.then the triangle XYZis mapped onto triangle RST under a reflection in the line y=1.write down the coordinates of the points R,S,T.
还有一题看不懂:
express:(a)136.80kg correct to the nearest 10kg
(b)0.06280 in standard form,correct to 2 significant figures.
ans:(a)_____________
(b)_____________
你先把题目给偶翻译一下...
在方格纸上回答以下问题。
ABC三点的坐标分别是(1,2),(2,2),(3,0)，给定的三角形ABC是通过三角形XYZ在同中心按比例放大两倍而成。而三角形XYZ与三角形RST关于直线y＝1对称。请写出点RST各自的坐标
rr在一张方格以下回答全部问题:
点 A B C的坐标分别是 (1,2)(2,2)(3,0),三角形ABC是三角形XYZ扩大两倍而成,三角形XYZ与三角形RST关于直线y＝1对称。
写下点 R S T 的坐标。
第二题
用式子表达
(A) 136.80千克改为以10千克为单位
(B)把0.06280 以科学计数法改写,保留两个有效数字
ans是snswer答案
R(0.5,1),S(1,1),T(1.5,2)
在一张方格之上回答全部问题:点 A ,B ,C的坐标分别是 (1,2),(2,2),(3,0),给定的三角形ABC是通过三角形XYZ在同中心扩大两倍而成,三角形XYZ与三角形RST关于直线y＝1对称.写下点 R ,S ,T 的坐标.第二题考察科学技术法的...
