Una lancha que viaja a 10 m/s pasa por debajo de un puente 3 segundos después que ha pasado un bote que viaja a 7 m/s, ¿después

ExtremeBDS [4]

Answer:

La lancha y el bote se encontrarán a 70 metros de distancia del puente.

Step-by-step explanation:

Sea el punto debajo del puente el punto de referencia y que ambas lanchas se desplazan a velocidad a continuación, las ecuaciones cinemáticas para cada embarcación son presentadas a continuación:

Bote a 7 metros por segundo

$x_{A} = x_{o}+v_{A}\cdot t$ (Ec. 1)

Lancha a 10 metros por segundo

$x_{B} = x_{o}+v_{B}\cdot (t-3\,s)$ (Ec. 2)

Donde:

$x_{o}$ - Posición debajo del puente, medido en metros.

$x_{A}$ , $x_{B}$ - Posición final de cada embarcación, medido en metros.

$v_{A}$ , $v_{B}$ - Velocidad de cada embarcación, medida en metros por segundo.

$t$ - Tiempo, medido en segundos.

Para determinar la posición en la que ambas embarcaciones se encuentran, se debe determinar el instante en que ocurre a partir de la siguiente condición: $x_{A} = x_{B}$

Igualando (Ec. 1) y (Ec. 2) se tiene que:

$v_{A}\cdot t = v_{B}\cdot (t-3\,s)$

Ahora despejamos el tiempo:

$3\cdot v_{B} = (v_{B}-v_{A})\cdot t$

$t = \frac{3\cdot v_{B}}{v_{B}-v_{A}}$

Si sabemos que $v_{B} = 10\,\frac{m}{s}$ y $v_{A} = 7\,\frac{m}{s}$ , entonces:

$t = \frac{3\cdot \left(10\,\frac{m}{s} \right)}{10\,\frac{m}{s}-7\,\frac{m}{s}}$

$t = 10\,s$

Ahora, la posición de encuentro es: ( $x_{o} = 0\,m$ , $v_{A} = 7\,\frac{m}{s}$ y $t = 10\,s$ )

$x_{A} = 0\,m + \left(7\,\frac{m}{s} \right)\cdot (10\,s)$

$x_{A} = 70\,m$

La lancha y el bote se encontrarán a 70 metros de distancia del puente.

I NEED HELP ASAP PLEASE PLOT IT

sergejj [24]

So for 1 1/3 you would go to 1 and count 3 lines after that and that is where you would plot it.

and for 2 4/9 you would count 4 lines after 2 but because there is only 6 lines you would divide by 2

What is the common denominator of StartFraction 1 Over a EndFraction StartFraction 1 Over b EndFraction in the complex fraction

stepladder [879]

The common denominator is 1

Given the expression:

$\frac{1/a-1/b}{1/a1/b}$

Find the LCM of the numerator to have:

$\dfrac{\frac{b-a}{ab} }{\frac{1}{a} \frac{1}{b} }$

Simplify both the numerator and the denominator to have:

$= \dfrac{\frac{b-a}{ab} }{\frac{1}{ab} }\\= \frac{b-a}{ab} \times ab\\=\frac{b-a}{1} \times 1 \\=\frac{b-a}{1}$

From the result, we can see that the common denominator is 1

Cory found a job listed in a classified that pays a yearly salary of $54,013. What is the biweekly

Anon25 [30]

Answer:

2077.42

Step-by-step explanation:

There are 52 weeks in a year, so there are 26 "biweekly" weeks in a year.

Cory receieves $54013 per year, so he gets 54013 / 26 dollars biweekly.

We can compute that number, getting 2077.42 dollars.
