- X: 4 units of A and 5 units of B per hour
- Y: 3 units of A and 10 units of B per hour
Cost to run machine X:$22/hr
Cost to run machine Y $25/hr
x=number of hours machine X runs
y=number of hours machine Y runs
The objective function is C = 22

The minimum cost is $
M and occurs at

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.
