An arena hosts a concert on friday a rodeo on saturday. if 12,211 people attend the concert and 9217 attend the rodeo, how many people visit the arena on friday and saturday?

21428 people visited the arena.

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.

definitely a. the others have almost all data points on one side of the line.
