The point-slope form:

y-y_1=m(x-x_1)

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points A(-2, 6) and B(2, -2). Substitute:

m=\dfrac{-2-6}{2-(-2)}=\dfrac{-8}{4}=-2\\\\y-6=-2(x-(-2))\\\\\boxed{y-6=-2(x+2)}\to\boxed{(B)}

The question is asking how many combinations of two people can be made from a group of ten people.

Using the formula C(10,2) = 10!/(2! x (10 - 2)! = 10!/(2! x 8!) = 45 handshakes.

A simple way to prove this is each person shakes the hand of 9 other people
10 x 9 = 90 but this counts every handshake from the view of both people involved.
The actual number of handshakes is therefore 90 / 2 = 45

In 1819, the United States purchased Florida from Spain for
Flura [38]

Answer:

<h3>D. 5 x 10⁶ ÷ 6.6 x 10⁴</h3>

Step-by-step explanation:

If 6.6 x 10^4 square miles of florida costs $5 X 10^6, then to get one square miles we will follow the given steps below;

6.6 x 10^4 mi² = $5 X 10^6

1mi² = $x

Cross multiply;

$5 X 10^6 * 1 = 6.6 x 10^4 * x

6.6 x 10⁴ x = 5 X 10⁶

Divide both sides by 6.6 x 10⁴  to get x;

6.6 x 10⁴ x /6.6 x 10⁴ = 5 x 10⁶/6.6 x 10⁴

x = 5 x 10⁶ ÷ 6.6 x 10⁴

x = 0.76*10⁶⁻⁴

<em>x = $0.76*10²</em>

<em />

Hence the key strokes on a calculator will give the cost the  United States paid for each square mile of Florida is 5 x 10⁶ ÷ 6.6 x 10⁴

Es la capacidad de un material para permitir que permitir que un liquido pase a trabes de el sin que se altere
pogonyaev

Answer:

Permeabilidad

Step-by-step explanation:

La permeabilidad es la medida de la capacidad o facilidad con la que un medio o material poroso permite el paso o la penetración de un fluido (líquido o gas) a través de él.

Un material altamente permeable como la grava permite que el fluido fluya a través de él fácilmente con poca restricción, de modo que prácticamente todo el fluido tiene el potencial de fluir a través de una columna de grava.

Un material poco permeable como la arcilla impide o restringe el flujo de fluido a través de él.

La permeabilidad se mide en un laboratorio utilizando muestras centrales de un material.

La unidad de permeabilidad es m²
