Answer:
The average acceleration of train is 
Step-by-step explanation:
We have,
A train that slows down from 15 m/s to 8.6 m/s in 1.2 s. It means that 15 m/s is its initial velocity and 8.6 m/s is its final velocity.
It is required to find the average acceleration of the train.

The average acceleration of train is
. Negative signs shows that the train is decelerating.
Answer:
The slope of the line is 2. To find the slope I marked two points on the line, which were (-3, 0) and (-2, 2). Then I used the
technique. Moving up 2 units and to the right 1 unit, which would be represented by
.
Answer:
work is shown and pictured
LCD(34, 45, 23) = LCM(4, 5, 3) = 22×3×5 = 60
34 = 4560
45 = 4860
23 = 4060
