Responder:
El remolque del tractor no atropellará a la vaca.
Explicación:
Dado lo siguiente:
Velocidad del tractor remolque: 69 km / h
Tiempo necesario para detenerse después de aplicar los frenos = 4 segundos
Distancia de vacas desde el remolque del tractor = 25 metros
Por lo tanto, la distancia recorrida por el remolque del tractor después de aplicar los frenos:
Velocidad del tractor remolque / Tiempo
69 km / h = (69 * 1000) m / 3600s = 69000m / 3600s = 19.17m / s
(19,17 m / s ÷ 4 s) = 4,8 m
Como la distancia de la vaca está más lejos (25 m), el remolque del tractor no pasará por encima de las vacas

Answer:
![S_{250} = 62750](https://tex.z-dn.net/?f=S_%7B250%7D%20%3D%2062750)
Explanation:
Given
![Sequence: 2 + 4 + 6 + ..... + 500](https://tex.z-dn.net/?f=Sequence%3A%202%20%2B%204%20%2B%206%20%2B%20.....%20%2B%20500)
Required
Evaluate the sequence
The sequence shows an arithmetic progression and will be solved using the sum of n terms of an Arithmetic Sequence as follows:
![S_n = \frac{n}{2}(a + L)](https://tex.z-dn.net/?f=S_n%20%3D%20%5Cfrac%7Bn%7D%7B2%7D%28a%20%2B%20L%29)
But first, we need to determine the value of n as follows:
![L = a + (n - 1)d](https://tex.z-dn.net/?f=L%20%3D%20a%20%2B%20%28n%20-%201%29d)
Where
![L = Last\ Term = 500](https://tex.z-dn.net/?f=L%20%3D%20Last%5C%20Term%20%3D%20500)
![a = First\ Term = 2](https://tex.z-dn.net/?f=a%20%3D%20First%5C%20Term%20%3D%202)
![d = Common\ Difference = 4 - 2 = 2](https://tex.z-dn.net/?f=d%20%3D%20Common%5C%20Difference%20%3D%204%20-%202%20%3D%202)
So:
![L = a + (n - 1)d](https://tex.z-dn.net/?f=L%20%3D%20a%20%2B%20%28n%20-%201%29d)
![500 = 2 + (n - 1) * 2](https://tex.z-dn.net/?f=500%20%3D%202%20%2B%20%28n%20-%201%29%20%2A%202)
Open bracket
![500 = 2 + 2n - 2](https://tex.z-dn.net/?f=500%20%3D%202%20%2B%202n%20-%202)
Collect Like Terms
![2n = 500 + 2 - 2](https://tex.z-dn.net/?f=2n%20%3D%20500%20%2B%202%20-%202)
![2n = 500](https://tex.z-dn.net/?f=2n%20%3D%20500)
Divide through by 2
![n = 250](https://tex.z-dn.net/?f=n%20%3D%20250)
So:
becomes
![S_{250} = \frac{250}{2}(2 + 500)](https://tex.z-dn.net/?f=S_%7B250%7D%20%3D%20%5Cfrac%7B250%7D%7B2%7D%282%20%2B%20500%29)
![S_{250} = 125(2 + 500)](https://tex.z-dn.net/?f=S_%7B250%7D%20%3D%20125%282%20%2B%20500%29)
![S_{250} = 125(502)](https://tex.z-dn.net/?f=S_%7B250%7D%20%3D%20125%28502%29)
![S_{250} = 125 * 502](https://tex.z-dn.net/?f=S_%7B250%7D%20%3D%20125%20%2A%20502)
![S_{250} = 62750](https://tex.z-dn.net/?f=S_%7B250%7D%20%3D%2062750)
<em>Hence, the sum of the sequence is 62750</em>
