Answer:

Step-by-step explanation:

No, in order for a set of numbers to be a function, it has to pass the vertical line test. Draw a vertical line to see if it intersects the line more than once. Another way to think about it, is that one singular x value cannot give two different y values. That is impossible.

For example at x = 0, there are two y values that relate to that point. I'm going to estimate the y value for simplicity and the purpose of explanation.

(0,2) and (0,-4)

Which models show 40%? Check all that apply. A model with 4 shaded sections and 6 unshaded sections. A model with 40 shaded sect

Amanda [17]

Answer:

A model with 4 shaded sections and 6 unshaded sections.

A model with 40 shaded sections and 60 unshaded sections.

Step-by-step explanation:

Required:

Which models shows 40%

(a) 4 shaded and 6 unshaded

First, we calculate the total sections

$Total = 4 + 6$

$Total = 10$

The percentage of the shaded section is:

$Shaded = \frac{4}{10} * 100\%$

$Shaded = 0.4 * 100\%$

$Shaded = 40\%$

(b) 40 shaded and 60 unshaded

First, we calculate the total sections

$Total = 40 + 60$

$Total = 100$

The percentage of the shaded section is:

$Shaded = \frac{40}{100} * 100\%$

$Shaded = 0.4 * 100\%$

$Shaded = 40\%$

(c) 2 shaded and 8 unshaded

First, we calculate the total sections

$Total = 2 + 8$

$Total = 10$

The percentage of the shaded section is:

$Shaded = \frac{2}{10} * 100\%$

$Shaded = 0.2 * 100\%$

$Shaded = 20\%$

<em>Hence, (a) and (b) shows 40%</em>

A side of a led lighting cube is 5 cm long. What is the area of its 6 faces?

ratelena [41]

Answer:

Of all 6 faces it would be 150

Step-by-step explanation:

If one side of the cube is 5cm long, then l × w = area of a face, so if it is a cube then all 4 sides are the same on a face so 5 × 5 = 25, so 25 × 6 faces = 150
