What values of cand d would make the following expression represent a real number?
i(2 +31)(c + di)
O c= 2, d = 3
Oc=-2, d=3
O c=3, d=-2
O C=-3, d = -2

c=3 d=2

Step-by-step explanation:

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.
