Is floor(x) periodic?

Mathematics

diamong [38]3 years ago

If you look at the graph of y = floor(x), you'll see a stairstep pattern that climbs up as you read from left to right. There are no vertical components to the graph. There are only horizontal components.

The graph is not periodic because the y values do not repeat themselves after a certain x value is passed. For instance, start at x = 0 and go to x = 3. You'll see the y values dont repeat themselves as if a sine function would. If you wanted the function to be periodic, the steps would have to go downhill at some point; however, this does not happen.

Conclusion: The function floor(x) is <u>not</u> periodic.

Answer:

No

Step-by-step explanation:

A periodic function has a period T such that, for every x, we have

f(x+T)=f(x)

In this case, it would mean that there exists a number T such that, for every x,

\lfloor x+T\rfloor = \lfloor x \rfloor

but we can always choose a value for x that is near enough (i.e. less than T) an integer. For example, if T=0.2, we can choose x=0.9 (which is 0.1 away from the next integer, which is less than 0.2).

This choice implies that x+T and x don't share the same integer part, and thus their floor is different:

\lfloor x+T\rfloor = \lfloor 0.9+0.2\rfloor =\lfloor 1.1\rfloor=1

whereas

\lfloor x \rfloor=\lfloor 0.9 \rfloor=0

A regular polygon has sides all the same length, and angles all the same measure. Find the pelmeter of the regular polygon below
Ede4ka [16]

The perimeter of the regular polygon is 70 inches

<h3>How to determine the perimeter of the regular polygon?</h3>

The sides of the regular polygon is given as:

Side = 10 in

The regular polygon has 7 sides

So, the perimeter of the polygon is calculated as:

P = Side lengths * Number of sides

This gives

P = 10 inches * 7

Evaluate

P = 70 inches

Hence, the perimeter of the regular polygon is 70 inches

Direction: Determine whether the given point is a solution to the given system of linear inequalities.
Ann [662]

Answer:

The given point is a solution to the given system of inequalities.

Step-by-step explanation:

Again, we can substitute the coordinates of the given point into the system of inequalities. We know that the x-coordinate and y-coordinate of (3,2) are x=3 and y=2, respectively.

Plugging these values into the first inequality, y\leq x+3, gives us 2\leq 3+3, which simplifies to 2\leq 6. This is a true statement, so the given point satisfies the first inequality. We still need to check if it satisfies the second inequality though, because if it doesn't, it won't be a solution to the system.

Plugging the coordinates into the second inequality, y\geq -x+3, gives us 2\geq -3+3, which simplifies to 2\geq 0. This is also a true statement, so the given point satisfies the second inequality as well. Therefore, \bold(\bold3\bold,\bold2\bold) is a solution to the given system of inequalities since it satisfies all of the inequalities in the system. Hope this helps!
