2. Un auto viaja a 60 km/h y se detiene a los 2 segundos. qué distancia recorrió en el
posledela

Se calcula que la aceleración es - 8,35 m/s.

<h3 /><h3>¿Qué es la aceleración?</h3>

Ahora sabemos lo siguiente de la pregunta;

Velocidad inicial (u) = 60 km/h o 16,7 m/s

Tiempo empleado (t) = 2 s

Dado que;

v = tu + en

v = 0 m/s porque el carro se detenía

tu = -en

a = -(u/t)

 a= -1(6,7 m/s/2 s)

a =- 8,35 m/s

La aceleración es negativa porque la velocidad disminuye con el tiempo.

Given the equation square root of 8x plus 1 = 5, solve for x and identify if it is an extraneous solution. x = one fourth, solut
Rainbow [258]

Answer:

x=3, solution is not extraneous

Step-by-step explanation:

we have

\sqrt{8x+1}=5

Solve for x

squared both sides

(\sqrt{8x+1})^2=5^2

8x+1=25\\8x=25-1\\8x=24\\x=3

<u><em>Verify</em></u>

For x=3

\sqrt{8(3)+1}=5

\sqrt{24+1}=5

\sqrt{25}=5

5=5 -----> is true

therefore

x=3, solution is not extraneous
