Answer:

Option B) add 5 to both sides of the equation

Step-by-step explanation:

we have

$x^{2}+18x+76=0$

step 1

Add 5 to both sides of the equation

$x^{2}+18x+76+5=0+5$

$x^{2}+18x+81=5$

step 2

Rewrite as perfect squares

$(x+9)^{2}=5$

Answer:

${10}^{th} \: term = \frac{5}{512}$

Step-by-step explanation:

geometric progression formula:

${n}^{th} \: term = ar ^{n - 1}$

given:

common ratio, r = 1/2

$first \: term \: = 5$

1) find the value of a

${n}^{th} \: term \: = a {r}^{n - 1}$

we're finding the 1st term, so substitute 1 into n:

${1}^{st} \: term = a( \frac{1}{2} ) {}^{1 - 1}$

first term is 5. so we substitute 5 into the equation:

$5 = a(1)$

$a = 5$

2) find the 10th term

we're finding the 10th term, so substitute 10 into the equation and don't forget to substitute 5 into a:

${10}^{th} \: term = 5( \frac{1}{2} ) {}^{10 - 1}$

${10}^{th} \: term = 5( \frac{1}{512} )$

${10}^{th} \: term = \frac{5}{512}$

Una empresa de comunicaciones internacional ofrece paquete de servicios de internet por demanda y que incluye un cargo fijo mens

just olya [345]

El costo por el consumo de 512 MB, con base en los cargos mencionados, es de $25408.

Cálculo del costo paso a paso.

Según los datos en el ejercicio, se puede identificar que el costo mensual debe contener el cargo fijo mensual ($8000), más los megabytes consumidos por $34, teniendo eso en cuenta, se puede generar la siguiente fórmula:

Costo por consumo = Cargo fijo mensual + MB * $34

Donde:

MB = Megabytes consumidas.

Si reemplazamos el valor de MB por la cantidad mencionada en el ejercicio (512 Mb), y el cargo fijo mensual ($8000) obtenemos:

Costo por consumo = $8000 + 512 * $34
Costo por consumo = $8000 + $17408
Costo por consumo = $25408

Por lo tanto, el costo por consumo de 512 Mb es de $25408.
