Since the exponent (-3) is negative, flip the expression to: 1/(5n^4)^3.

Notice how the negative exponent becomes positive as you flip it.

Now evaluate the powers in the denominator: 1/((5^3)(n^4)^3

I separated the constant (5) from the variable (n) to show you how the powers are evaluated.

1/(5x5x5)(nxnxnxn)(nxnxnxn)(nxnxnxn)
—-> the power four means that there are 4 multiples of n in the parentheses. The power 3 corresponds to how many groups.

1/(125)(n^12)

= 1/125n^12

Which of the following lines goes downwards from left to right?
Delicious77 [7]
"Goes downwards from left to right" is basically saying that the slope of this line is negative. We go downhill from left to right. 

y = 2x+5 has a positive slope because m = 2 is the slope (b = 5 is the y intercept)
So choice A is out

Similarly choice B is eliminated as well because the slope is also m = 2

Choice C is false as well. The slope here is m = 2 (think of y = 2x as y = 2x+0)

The only choice with a negative slope is choice D. The slope is m = -2 

This is why the answer is choice D

Side Note: I'm using slope intercept form y = mx+b where m is the slope and b is the y intercept

Answer:

I don't know what is in the drop down question, but here are the answers for the others:

1. Triangle possible

2. Triangle possible

3. Triangle possible

4. Triangle not possible

Angles need to add up to 180.

The 2 smallest sides have to be greater summed up than the 3rd side.

Hope this helps!

Please put brainliest if possible.

Ejercicio Nº 4 Desde la parte superior de un acantilado de 80 metros de altura se dispara horizontalmente una piedra a razón de
vaieri [72.5K]

Answer:

1) La piedra permanece en el aire en 4 segundos.

2) La piedra alcanza una distancia horizontal de 32 metros.

3) La velocidad de la piedra con la que alcanza el suelo es aproximadamente 40.792 metros por segundo.

Step-by-step explanation:

El problema nos indica un caso de tipo parabólico, el cual consiste en la suma de un movimiento horizontal a velocidad y un movimiento uniforme acelerado por la gravedad desde el reposo.

1) El tiempo total que la piedra permanecería en el aire es tiempo requerido entre la parte superior del acantilado y el fondo. La ecuación cinemática que vamos a utilizar es la siguiente:

y = y_{o} + v_{o,y}\cdot t +\frac{1}{2}\cdot g \cdot t^{2} (Ec. 1)

Donde:

y_{o} - Altura inicial, medida en metros.

y - Altura final, medida en metros.

v_{o,y} - Velocidad vertical inicial de la piedra, meadida en metros por segundo.

g - Aceleración gravitacional, medido en metros por segundo al cuadrado.

t - Tiempo, medido en segundos.

Si sabemos que y_{o} = 80\,m, v_{o,y} = 0\,\frac{m}{s} y g = -10\,\frac{m}{s^{2}}, entonces encontramos la siguiente función cuadrática:

-5\cdot t^{2}+80 = 0 (Ec. 2)

El tiempo en el que la piedra permanece en el aire es:

t = 4\,s

La piedra permanece en el aire en 4 segundos.

2) La distancia horizontal es descrita por la siguiente fórmula cinemática:

x = x_{o}+v_{o,x}\cdot t (Ec. 3)

Donde:

x_{o} - Posición horizontal inicial, medido en metros.

x - Posición horizontal final, medido en metros.

v_{o,x} - Velocidad horizontal inicial de la piedra, medida en metros por segundo.

Si sabemos que x_{o} = 0\,m, v_{o,x} = 8\,\frac{m}{s} and t = 4\,s, entonces la distancia horizontal alcanzada por la piedra es:

x = 0\,m + \left(8\,\frac{m}{s}\right)\cdot (4\,s)

x = 32\,m

La piedra alcanza una distancia horizontal de 32 metros.

3) En primer lugar, determinamos los componentes vertical y horizontal de la velocidad final de la piedra por medio de las siguientes fórmulas cinemáticas:

Velocidad final horizontal (v_{x}), medida en metros por segundo.

v_{x} = \frac{x-x_{o}}{t} (Ec. 4)

Velocidad final vertical (v_{y}), medida en metros por segundo.

v_{y} = v_{o,y}+g\cdot t (Ec. 5)

Si x = 32\,m, x_{o} = 0\,m. t = 4\,s, v_{o,y} = 0\,\frac{m}{s} y  g = -10\,\frac{m}{s^{2}}, los componentes de la velocidad final de la piedra son:

v_{x} = \frac{32\,m-0\,m}{4\,s}

v_{x} = 8\,\frac{m}{s}

v_{y} = 0\,\frac{m}{s}+\left(-10\,\frac{m}{s^{2}} \right) \cdot (4\,s)

v_{y} = -40\,\frac{m}{s}

Por último, determinamos la velocidad final de la piedra por Teorema de Pitágoras:

v = \sqrt{v_{x}^{2}+v_{y}^{2}} (Ec. 6)

v = \sqrt{\left(8\,\frac{m}{s} \right)^{2}+\left(-40\,\frac{m}{s} \right)^{2}}

v \approx 40.792\,\frac{m}{s}

La velocidad de la piedra con la que alcanza el suelo es aproximadamente 40.792 metros por segundo.
