The ten sides of a regular decagon are colored with five different colors, so that all five colors are used, and sides that are

const2013 [10]

Answer:

120

Explanation:

Number the sides of the decagon: 1, 2, 3, 4, 5, 6, 7, 8, 9, and 10, from top (currently red) clockwise.

The side number one can be colored of five different colors (red, orange, blue, green, or yellow): 5

The side number two can be colored with four different colors: 4

The side number three can be colored with three different colors: 3

The side number four can be colored with two different colors: 2

The side number five can be colored with the only color left: 1

Each of the sides six through ten can be colored with one color, the same as its opposite side: 1

Thus, by the multiplication or fundamental principle of counting, the number of different ways to color the decagon will be:

5 × 4 × 3 × 2 ×1 × 1 × 1 × 1 × 1 × 1 = 120.

Notice that numbering the sides starting from other than the top side is a rotation of the decagon, which would lead to identical coloring decagons, not adding a new way to the number of ways to color the sides of the figure.

What is the domain of f(x) = 2^x?

hammer [34]

The given function has no undefined points nor domain constraint. Thus, the domain is: $-\infty \: < x < \infty$ .

<h3>Domain and Range</h3>

The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined. An example, there is a restriction for the domain of fractions. The variable x in the denominator should be different of zero.

While the domain is related to the values of x, the range is related to the possible values of y that the function can have.

In this question, the function $2^x$ has no undefined points nor domain constraint. Therefore, the domain is: $-\infty \: < x < \infty$

Write the equation of the quadratic graph in the form f(X)= a(x-h)^2+k

goldfiish [28.3K]

Answer:

f(x) = 2(x - 5)² - 6

Step-by-step explanation:

Vertex Formula: y = a(x - h) + k; Vertex: [h, k]; there is a vertical stretch at 2 = a. The -h [phase shift (horizontal shift)] in parentheses gives you the OPPOSITE term of what it really is, so really, 5 = h. Now, k [vertical shift] is the ONLY normal term, so -6 = k.
