Analyze the graph of the exponential decay function.

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.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

80 the answer is 80

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
