Answer 1

Answer:

For this case, we have that by definition:

$(-0.5) ^ 3 = -0.125$

Then we can rewrite the given expression as:

$\sqrt [3] {(- 0.5) ^ 3}$

For properties of roots we have that:

$\sqrt [n] {(a) ^ n} = a$

So:

$\sqrt [3] {(- 0.5) ^ 3} = - 0.5$

So, we have to:

$\sqrt [3] {- 0.125} = - 0.5$

Considere as mesas com 4 cadeiras, com 6 cadeiras e com 8 cadeiras. ©Shutterstock/jenjira Com base nessa sequência de imagens, qual expressão indica a quantidade de cadeiras utilizadas ao colocarmos n mesas lado a lado?

Answers

Responder:

C. Tₙ = 2n + 2

Explicación paso a paso:

De la pregunta, la secuencia de imágenes, cuya expresión indica es 4 cadeiras, 6 cadeiras, 8 cadeiras ...

Se puede ver la secuencia una progresión aritmética de la forma 4, 6, 8 ... Para obtener la expresión que indica la cantidad de cadenas utilizadas o colocaremos n tablas una al lado de la otra, tendremos que encontrar el enésimo término de la secuencia que usa la fórmula para encontrar el enésimo término de una secuencia aritmética.

El enésimo término de un AP se expresa como Tₙ = a + (n-1) d donde;

a es el primer término

n es el número de términos es la diferencia común

De la secuencia generada, a = 4, d = 6-4 = 8-6 = 2

Tₙ = 4+ (n-1) 2

abre el paréntesis

Tₙ = 4 + 2n-2

Tₙ = 2n + 4-2

Tₙ = 2n + 2

Por lo tanto, la expresión que indica la cantidad de cadenas utilizadas o colocaremos n tablas una al lado de la otra es 2n + 2

Solve the following equation for the given variable 3(x+6)=-9

Answers

Answer:

x = -9

Step-by-step explanation:

3(x+6)=-9

Divide each side by 3

3/3 *(x+6)=-9/3

x+6 = -3

Subtract 6 from each side

x+6-6 = -3-6

x = -9

Answer:

Step-by-step explanation:

so... 3(x+6)=-9

at 1st you do 3*x which is 3x then 3*6=18

all together is (3x+18)=-9

then get rid of brackets 3x+18=-9

after that take away 18 from both sides 3x+18=-9

-18 -18

which is 3x = -27

then you divide 3 in the both side

its going to be 3x = -27

3/3=1x or x then -27/3 = -9

so x = -9

Solve for the unknown.a) sin (x – 5°) = cos (35°)

b) sin (2x – 17°) = cos (x – 4°)

c) sin (x)= cos (x)

Show steps

Answers

Step-by-step explanation:

Use shifts to write sine and cosine in terms of each other.

a) sin (x – 5°) = cos (35°)

sin (x – 5°) = sin (90° – 35°)

sin (x – 5°) = sin (55°)

x – 5° = 55°

x = 60°

b) sin (2x – 17°) = cos (x – 4°)

sin (2x – 17°) = sin (90° – (x – 4°))

sin (2x – 17°) = sin (90° – x + 4°)

sin (2x – 17°) = sin (94° – x)

2x – 17° = 94° – x

3x = 111°

x = 37°

c) sin (x) = cos (x)

sin (x) = sin (90° – x)

x = 90° – x

2x = 90°

x = 45°
