Answer:

22.68

Step-by-step explanation:

The first step is to find the amount of tax

tax = original cost * tax rate

       = 21 * 8%

       = 21 * .08

      =1.68

Then we add the tax to the original cost to find the total cost

total cost = original cost + tax

               = 21 + 1.68

               =22.68

B(n) = -1 (2)^n-1 What is the 5th term in the sequence?
bija089 [108]

Answer:

<h2>The answer is - 16</h2>

Step-by-step explanation:

<h3>b(n) =  - 1 ({2})^{n - 1}</h3>

where

n is the number of terms

From the question since we are finding the 5th term

n = 5

Substitute the value into the above formula and solve

We have

b(5) =  -  1({2})^{5 - 1}  \\  =  - 2 ^{4}

We have the final answer as

<h3>- 16</h3>

Hope this helps you

Dos cuadrados de lado
Kaylis [27]

La franja amarilla del rectángulo tiene un área de 30 centímetros cuadrados.

<h3>¿Cuál es el área de la franja amarilla del rectángulo?</h3>

En este problema tenemos un rectángulo formado por dos cuadrados que se traslapan uno al otro. La franja amarilla es el área en la que los cuadrados se traslapan. La anchura del rectángulo es descrita por la siguiente ecuación:

(10 - x) + 2 · x = 17

Donde x se mide en centímetros.

A continuación, despejamos x en la ecuación descrita:

10 + x = 17

x = 7

Ahora, el área de la franja amarilla se determina mediante la fórmula de area de un rectángulo:

A = b · h

Donde:

  • b - Base del rectángulo, en centímetros.
  • h - Altura del rectángulo, en centímetros.
  • A - Área del rectángulo, en centímetros cuadrados.

A = (10 - 7) · 10

A = 3 · 10

A = 30

El área de la franja amarilla del rectángulo es igual a 30 centímetros cuadrados.
