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:
There is a circle with a diameter[d] of 2.
Step-by-step explanation:
the Radius=diameter /2=2/2=1 units
now
circumference=2πr=2×π×1=6.29=6 units
area=πr²=3.14 unit²
400,000,000 + 30,000,000 + 200,000 + 90,000 +100
Answer: -7
Step-by-step explanation:
First, lets use the functions to find the answer to f(-8) and g(4)
f(-8) is the same as asking for the value of y when x is -8
Therefore, f(-8) = -5 (according to the graph)
Using the same rule, g(4) would be the value of y when x = 4 which,
according to the graph, g(4) = 3
Plug these values back into the original equation to get:

using the order of operations, we will multiply the values first

<h2>Therefore, our final answer is -7</h2>
