Answer:
The train will travel 493.817 meters until it stops completely.
Step-by-step explanation:
In this case, we know that train applies the brakes and decelerates at constant rate until rest is reached after travelling an unknown distance. Travelled distance (
), measured in meters, can be found by using this kinematic formula:
(Eq. 1)
Where:
- Initial speed, measured in meters per second.
- Final speed, measured in meters per second.
- Acceleration, measured in meters per square second.
Now travelled distance is cleared within the formula:

If we know that
,
and
, then the distance travelled by the train is:


The train will travel 493.817 meters until it stops completely.
Answer:
I think it is B. It does not look comparable.
There are 365 days in a year, well,unless is a leap-year, but we're assuming 365 days per year, now, "t" is how many years it takes for population to grow to "P" much, however, 1 day in year terms is really just 1/365 year or about 0.003 years, and 2 days is just 2/365 year, and 3 days is 3/365 year and so on, thus,
Y = -3x + 6....the slope here is -3. A parallel line will have the same slope.
y = mx + b
slope(m) = -3
(-4,7)....x = -4 and y = 7
now we sub into the formula and find b, the y int
7 = -3(-4) + b
7 = 12 + b
7 - 12 = b
-5 = b
so ur parallel equation is : y = -3x - 5 <==
