Tentukanlah bayangan titik A(4,6) setelah dilatasikan dengan faktor skala 5 dan pusatnya P(3,2)
nikolasjerry
Geser sesuai pusat dilatasi = (4-3,6-2) = (1,4). lalu kali dgn faktor skala menjadi (5,20). kembalikan ke titik asal (5+3, 20+2) = (8,22 )bayangannya. semoga ini bisa membantu kamu. jadikan yang terbaik ya
