First week = 5 + 1 = 6 books
Second week = 5 + 1 +1 = 7 books
So each week he got one more book from the library and had a total of the number of books he recently got plus the number from the beginning, 5.

<span>d) y=5+x

Hope this helps :)

What is the value of b for the following circle in general form? x2 + y2 + ax +by+c=0​
liberstina [14]

Answer:

Step-by-step explanation:

<u><em>(1).</em></u> (x - <em>h</em>)² + (y - <em>k</em>)² = <em>r</em>²

where <em>(h, k)</em> are coordinates of a center of the circle with radius <em>r</em>

<u><em>(2).</em></u> ( a ± b )² = a² ± 2ab + b²

~~~~~~~~~~~~~~

( 1 , - 2 ) ; r = 3

( x - 1 )² + ( y + 2 )² = 3²

x² - 2x + 1 + y² + 4y + 4 = 9

x² + y² - 2x + 4y - 4 = 0

a = - 2

b = 4

c = - 4

A recent trend in advertising is viral marketing. The goal is to convince viewers to share an amusing advertisement by e-mail or
77julia77 [94]
I'm not sure what you are looking for but I'll answer this question based on what I think is needed.

Given:
Day 1: 130 
Day 2: 130 x 4 = 520
Day 3: 520 x 4 = 2,080

The exponential equation of this problem is:
V(n) = 130(4)^n

Where n is the number of days since the video was first shown.

Let us assume that 10 days have past. Total view would be:

V(n) = 130(4)^n

V(10) = 130(4)^10
V(10) = 130(1,048,576)
V(10) = 136,314,880

After 10 days, there are more than 136 Million views of the viral video.

Se ha decidido repoblar con 150 000 árboles una zona asolada por un incencio. Se quieren plantar los árboles formando un cuadrad
Dmitrij [34]

Responder :

Se plantarán 149769 árboles

Explicación paso a paso:

Dado que:

Número de árboles a plantar = 150.000

Los árboles deben disponerse para formar un cuadrado;

La cantidad de árboles que se pueden plantar para hacer el cuadrado más grande posible:

Área de un cuadrado = s²

Dónde; s = Longitud de cualquier lado; ya que todos los lados son iguales.

El mayor número de árboles que se pueden plantar es el cuadrado perfecto más alto hasta 150.000.

Esto se puede obtener tomando la raíz cuadrada de 150000

Cuadrado (150.000)

= 387,29833

El cuadrado del número entero da el valor cuadrado perfecto más alto antes de 150 000

Por lo tanto,

s = 387 =; 387

Cantidad total de árboles; s² = 387² = 149769
