Aside from lowering worker productivity, artificial light sources are also costly, typically constituting anywhere from 25 to 50 per cent of a building’s energy use.

<h3>What are Artificial light sources?</h3>

In the late 19th and early 20th centuries, electric energy sources were used to generate artificial lighting. The goal of technological development for artificial lighting is to create light that will approximate natural sunshine (sunlight). The frequency range of an artificial light source and the intensity of illumination, expressed in lumens, are the two metrics used to measure artificial light. According to its progressive generation and the technology that made it possible, artificial light can be divided into three main sources.

Answer:

15

Step-by-step explanation:

Let volume of container = x

1/6x + 5 = 1/2x

x/6 + 5 = x/2

Multiply through by 6

x + 30 = 3x

Subtract 30 from both sides

x + 30 - 30 = 3x - 30

x = 3x - 30

x - 3x = - 30

-2x = - 30

x = 30 /2

x = 15

Which function has a vertex at the origin?

Crank

Answer:

B) $f(x)=x(x-4)$

Step-by-step explanation:

To find the function which has vertex at the origin.

Solution:

For a function to have its vertex at origin the function must pass through point (0,0) which means $f(0)=0$ .

We will find $f(0)$ for each of the given functions and check if it has vertex at origin.

To find $f(0)$ we will plugin $x=0$ in the function.

A) $f(x)=x+4$

$f(0)=0+4=4$

Vertex is not at the origin.

B) $f(x)=x(x-4)$

$f(0)=0(0-4)=0$ [Any number times zero is = zero]

Vertex is at the origin.

C) $f(x)=(x-4)(x+4)$

$f(0)=(0-4)(0+4)=(-4)(4)=-16$

Vertex is not at the origin.

D) $f(x)=2$

$f(0)=2$

Vertex is not at the origin.
