Answer 1

Date Page Given, parabola with vertex (0,0) and focus at (a,0) a=2.8cm let equation of parabola with vertex ch , K) Cy-K)² = 4 alath) ie, Chik) is vertex h=0 K=0 = y² = 4ax Now, focus and vertex lie on the same horizontal line y = 0 a = 2,8-0 = 2.8 0 is equation of parabolic reflector 92= 4(2.8) - y2 = (11.2) 3] x is in cui
