Answer:

Vertical angles are always equal to one another. In general, we can say that, 2 pairs of vertical angles are formed when two lines intersect.

Step-by-step explanation:

Parallel lines are lines that do not meet at any point in a plane.

Intersecting lines are straight lines that meet or crosses each other at a certain point.

The given equation is :

$xy = - 2$

1. The relationship such that dependent variable (y) is isolated is :

$y = \dfrac{ - 2}{x}$

2. The table accompanying this equation :

x = -4 and y = 0.5

x = -1 and y = 2

x = - 0.5 and y = 4

x = 0 and y = undefined

x = 0.5 and y = -4

x = 1 and y = -2

x = 4 and y = -0.5

A mold professional uses an antimicrobial chemical in an attic to combat a colony of mold. If the initial number of mold spores

kykrilka [37]

It would take about 57 hours for the number of spores to be less than 500 spores.

<h3>Exponential Function</h3>

An exponential function is in the form:

y = abˣ

Where y,x are variables, a is the initial value of y and b is the multiplication factor.

Let y is the number of pores after x hours.

a = 6200, b = 100% - 20% = 0.8, hence to be less than 500 spores:

$6200(0.8)^\frac{x}{5} < 500$

(x/5) * ln(0.8) < ln(0.08)

x > 56.4 hours

It would take about 57 hours for the number of spores to be less than 500 spores.

Observa las dimensiones del siguiente portarretrato, y escribe la expresión que determina el área disponible para la fotografía

777dan777 [17]

Answer:

Step-by-step explanation:

The dimensions of the portrait are attached.

The total area of the portrait is represented by its width 5+x and its length x+1.

We know by definition that the area of a rectangle is

$A= w \times l$

Where $w$ is the width and $l$ is the length.

Using the given expressiones, we have

$A=(5+x)(x+1)=5x+5+x^{2} +x=x^{2} +6x+5$

Therefore, the right answer is D.
