Braking distance. The data in the table shows the braking distance of Cheryl's car travelling at different speeds just before the brakes are applied. Speed 12.5 15 16.7 20 26.7 29.2 33.3 (m/s) Braking distance 7.80 11.3 13.9 20.0 35.6 42.5 55.6 (m) 12 (i) The data can be modelled by d = v²/k +c , where d represents the braking distance in metres, v represents the speed in m/s and k is a non-zero constant. State the value of c and give a reason for your answer.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
