which rule describes the composition of transformations that map ∆abc to ∆a"b"c"?

Step-by-step explanation:

From ABC to A'B'C'

it is a rotation 90 degrees anticlockwise about the origin i.e (0,0)

From A'B'C' to A''B''C''

It is a reflection about the x axis.

constant acceleration- a

constant velocity- c

no velocity or acceleration- b

explanation:

for body moving with a constant acceleration, the rate of change of displacement changes over time. this is proven by the increasing gradient of the curve (a) against time.

a body that is moving at constant velocity covers equal distances over equal periods of time, thus the straight line with a constant gradient c.

a stationary body   covers no displacement as time elapses. thus the flat line with   zero gradient.

answer: -1
