Step-by-step explanation:

[tex] {5}^{2} = {x}^{2} + {x}^{2} \\ {5}^{2} = {x}^{4} \\ 5 = \sqrt{ {x}^{4} } \\ 5 = {x}^{2} \\ x = \sqrt{5} =2.236068\\ [/tex]

the first four terms of the sequence is 51,51.8,52.6,53.4

we can find first four terms by using formula given by

[tex]a_{n} =a_{1} +(n-1) *d[/tex]

[tex]a_{n}[/tex] = the nᵗʰ term in the sequence

[tex]a_{1[/tex] = the first term in the sequence

d = the common difference between terms

Arithmetic progression is a progression in which every term after the first is obtained by adding a constant value, called the common difference (d). So, to find the nth term of an arithmetic progression, we know an = a1 + (n – 1)d. a1 is the first term, a1 + d is the second term, the third term is a1 + 2d, and so on

an=51 + (n-1)*0.8, n=1, 2, 3...

a1 = 51 + (1 -1 ) * 0.8

a1 = 51

a2 = 51 + (2 - 1)*0.8

a2 = 51 + 0.8

a2 = 51.8

a3 = 51 + (3 - 1)*0.8

a3 = 51 + 2*0.8

a3 = 51 + 1.6

a3 = 52.6

a4 = 51 + (4 - 1)*0.8

a4 = 51 + 2.4

a4 = 53.4

Hence , the first four terms of the sequence is 51,51.8,52.6,53.4

the complete question is

Find the first four terms of the sequence given by the following.

an=51 + (n-1)*0.8, n=1, 2, 3...

Answer:

1/6 and 1/7

Step-by-step explanation:

1/6 and 1/7

As we can see the denominator keeps increasing by 1 but the numerator stays as 1 :

1/1 or 1 is the first term

1/2 is the 2nd term

1/3 is the 3rd term

So :

1/6 is the 6th term

and 1/7 is the 7th term

Answer:

a) Hay 210 grupos diferentes de seis ciudades que el representante de ventas podrá seleccionar.

b) Hay 720 secuencias posibles existen para las seis ciudades designadas.

Step-by-step explanation:

a)  Se llama combinaciones de m elementos tomados de n en n a todas las agrupaciones posibles que pueden hacerse con los m elementos de forma que no entran todos los elementos , no importa el orden  y no se repiten los elementos. La combinación se calcula como:

[tex]C=\frac{m!}{n!*(m-n)!}[/tex]

En este caso m corresponde a las 10 ciudades en el área geográfica que va a visitar, mientras que n corresponde a las 6 ciudades que debe visitar un representante de venta durante un viaje.

Entonces:

[tex]C=\frac{10!}{6!*(10-6)!}=\frac{10!}{6!*4!}[/tex]

Considerando que el factorial ! indica que se deben multiplicar todos los números enteros y positivos que hay entre el número que aparece en la fórmula y el número 1, entonces la combinación dará como resultado:

C= 210

Hay 210 grupos diferentes de seis ciudades que el representante de ventas podrá seleccionar.

b) Se llama permutación de n elementos a cada una de las diferentes ordenaciones  que se pueden hacer con esos elementos.

Si se tiene un grupo de n objetos distintos, el número de maneras diferentes que podemos tomar un número r de objetos (r < n) del grupo, está dado por la fórmula de la permutación:

[tex]P=\frac{n!}{(n-r)!}[/tex]

Si m=n para calcular el total de permutaciones se utiliza la fórmula:

P= n!

En este caso se utiliza esta última expresión, ya que se desea calcular las permutaciones de 6 ciudades en 6 posiciones:

P=6!

P=720

Hay 720 secuencias posibles existen para las seis ciudades designadas.

Answer: The equation is w*(w-3)= 180 & Alex is 15 years old

Step-by-step explanation:

Alex= w years old

Claudia= (w-3) years old

a) Equation, w*(w-3)= 180

b) Now,

         w*(w-3)= 180

      ⇒ w²-3w-180= 0

      ⇒ (w+12)*(w-15)= 0

      ⇒ w= 15

Alex is 15 years old

Claudia is (15-3) = 12 years old

The shape that would not fit this description is a trapezoid.

It is a quadrilateral that has one pair of parallel sides and a height.

The area is calculated as 1/2 x the sum of the parallel sides x height.

Examples:

Area of a trapezium that has the parallel sides as 3 cm and 4 cm and a heght o 5 cm.

Area = 1/2 x (3 + 4) x 5

Area = 1/2 x 7 x 5

Area = 35/2 = 17.5 cm^2

We have,

A parallelogram is a four-sided shape where opposite sides are parallel and congruent.

If a parallelogram has diagonals that are congruent, it must be a rectangle.

Therefore, the shape that would not fit this description is any shape that is not a rectangle.

Out of the shapes given,

A trapezoid is not a rectangle and does not have diagonals that are congruent.

Therefore,

The shape is a trapezoid.

Answer:

Step-by-step explanation:

Given the conversion factor;

2inches = 30feet

if the height of the building is 180feet, we are to find the height of the scale model in inches.

Let x = 180 feet.

Equating both;

2inches = 30feet

x inches = 180feet

Cross multiply;

30 * x = 2 * 180

30x = 360

x = 360/30

x = 12inches

Hence the height of the scale model in inches is 12inches

Answer: 60 in

Step-by-step explanation:Let x = 180 feet.

Equating both;

2 inches = 30 feet

x inches = 180 feet

Cross multiply;

30 * x = 2 * 180

30 x = 360

x = 360/30

x = 60 inches

The slope of the graphed linear equation is a = 3/4.

A general linear equation is of the form:

y = a*x + b

Where a and b are real numbers, a is the slope, and b is the y-intercept.

If a line passes through two points (x₁, y₁) and (x₂, y₂), then the slope of that linear equation is given by:

a = (y₂ - y₁)/(x₂ - x₁)

Now, we can look at the graph to identify two points on the line, we can use (20, 40) and (60, 70), using the above formula we can get the slope:

a = (70 - 40)/(60 - 20)

a = 30/40 = 3/4

The slope of the graphed linear equation is a = 3/4.
