Time series data refers to a collection of data points that are measured over time at regular intervals. The time series data could refer to various metrics such as sales, revenue, foot traffic, website traffic, inventory levels, and other relevant business metrics that change over time.

By analyzing time series data, businesses can gain insights into trends, patterns, and other factors that can affect their operations.  

Time series can be used for forecasting. By analyzing past trends and patterns, businesses can make predictions about future performance and take proactive measures to achieve their goals.  

Since the time series will follow the trend, have multiple choices, and will be cyclical and it will analyze the patterns over time periods seasonally.

Answer:

Step-by-step explanation:

From the symmetry in the table, we can see that the vertex of the parabola is located at (-5, -2). We will pick another point from the table to use in our model to solve for the a value, just in case there is one. I picked (-4, -1). Any point from the table will work.

Our model is

\(y=a(x-h)^2+k\) where h and k are the coordinates of the vertex and x and y are the coordinates from the other point chosen from the table. Filling in to solve for a:

\(-1=a(-4+5)^2-2\) and

\(-1=a(1)^2-2\) and

-1 = a - 2 so

a = 1.

Now we can fill in the equation with the coordinates of the vertex and the value found for a to get

\(y=(x+5)^2-2\) You don't need to put the 1 out in front; it's unnecessary. Your choice is the last one there in the list.

slope ≈ -0.00615

b)  the section of the road measured horizontally is approximately 3983.74 cm long.

Step-by-step explanation:

change in horizontal distance = (change in vertical distance) / slope

change in horizontal distance = (-24.5 cm) / (-0.00615)

change in horizontal distance ≈ 3983.74 cm

The equation that best describes the relation is y = -x+1 ( optionD)

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.

Taking x(0,1) and y ( 1,0)

therefore the slope of the line

= 0-1/1-0

= -1/1 = -1

the equation a line is given as

y-y1 = m(x-x1)

= y-1 = -1( x - 0)

= y-1 = -x

y = -x +1

therefore the equation that describe relation is y = 1-x or y = -x+1

The input value that produces the same output value for the functions f(x) and g(x) is x = -1.

To find the input value that produces the same output value for the functions f(x) and g(x), we need to compare the corresponding values in the tables for both functions.

Looking at the table for f(x), we see that the output value -1 is listed in the column for f(x) when x = -1.

In the table for g(x), we find that the output value -1 is also listed in the column for g(x) when x = -1.

Since both functions have the same output value (-1) for the input value x = -1, we can conclude that x = -1 produces the same output value for f(x) and g(x).

Therefore, the correct answer is x = -1.

Answer:

(-28,-11)

Step-by-step explanation:

y = \(\frac{1}{4}\) x - 4  Substitute 4 for x

y = \(\frac{1}{4}\)\((\frac{4}{1})\) - 4  another name of 4 is \(\frac{4}{1}\)

y = 1 - 4

y = -3

(4,-3)

y = \(\frac{1}{4}\) x - 4  Substitute -11 for y

-11 = \(\frac{1}{4}\) x - 4  Add 4 to both sides

-11 + 4 = \(\frac{1}{4}\)x - 4 + 4

-7 = \(\frac{1}{4}\)x  Multiply both sides by 4

-7(4) = \(\frac{1}{4}\)\((\frac{4}{1})\)x

The measure of angle DFE is given as follows:

<DFE = 62º.

To obtain the measures, we consider that the sum of the measures of the internal angles of a triangle is of 180º.

The internal angle measures for this problem are given as follows:

Hence the value of x is obtained as follows:

180 - 5x + 14 + 44 + 3x - 10 = 180

228 - 2x = 180

Answer:

The original number is -22

Step-by-step explanation:

We'll label our mystery number x.

2x + 36 = 4x/11
Multiply both sides by 11
4x = 22x + 396
Isolate x to one side (for this I subtract 4x from both sides, but you can also subtract 22x if you'd like)
0 = 18x + 396
Isolate x pt 2
18x = -396
Divide both sides by 18 to find your answer!
x = -22

Plug in to confirm

-44 + 36 = -88/11S

I don't know what table you have as reference, but I suspect it includes the following transforms:

\(1 \leftrightarrow \dfrac1s\)

\(e^{at} \leftrightarrow \dfrac{1}{s-a}\)

\(\cos(at) \leftrightarrow \dfrac{s}{s^2+a^2}\)

\(\sin(at) \leftrightarrow \dfrac{a}{s^2+a^2}\)

\(\cosh(at) \leftrigharrow \dfrac{s}{s^2-a^2}\)

\(\sinh(at) \leftrigharrow \dfrac{a}{s^2-a^2}\)

It probably also includes some more general properties, like

\(t f(t) \leftrightarrow -F'(s)\)

\(e^{at} f(t) \leftrightarrow F(s-a)\)

where F(s) is the Laplace transform of f(t).

Beyond these, you should also know the following identities:

\(\cosh(t) = \dfrac{e^t + e^{-t}}2\)

\(\cosh^2(t) = \dfrac{1 + \cosh(2t)}2\)

\(\cos^2(t) = \dfrac{1 + \cos(2t)}2\)

\(\sin^2(t) = \dfrac{1 - \cos(2t)}2\)

\(\sin(2t) = 2 \sin(t) \cos(t)\)

\(\sin(t \pm T) = \sin(t) \cos(T) \pm \cos(t) \sin(T)\)

Putting everything together, we have

• (a)

\(\cosh(t) \sin(t) = \dfrac{e^t + e^{-t}}2 \times \sin(t) = \dfrac12 e^t \sin(t) + \dfrac12 e^{-t} \sin(t)\)

and the Laplace transform is

\(\dfrac12 F(s - 1) + \dfrac12 F(s + 1)\)

where F(s) is the transform of sin(t),

\(F(s) = \dfrac{1}{s^2 + 1}\)

Then

\(\cosh(t) \sin(t) \leftrightarrow \dfrac{\frac1{(s-1)^2+1} + \frac1{(s+1)^2+1}}2 = \boxed{\dfrac{s^2+2}{s^4+4}}\)

• (b)

\(\sin^2(t) = \dfrac12 \left(1 - \cos(2t)\right)\)

and the transform is

\(F(s) = \dfrac12 \left(\dfrac1s - \dfrac{s}{s^2+4}\right) = \boxed{\dfrac{2}{s^3+4s}}\)

• (c)

\(\cos^2(2t) = \dfrac12 \left(1 + \cos(4t)\right)\)

with transform

\(F(s) = \dfrac12 \left(\dfrac1s + \dfrac{s}{s^2+16}\right) = \boxed{\dfrac{s^2+8}{s^3+16s}}\)

• (d)

\(\cosh^2(t) = \dfrac12 \left(1 + \cosh(2t)\right)\)

with transform

\(F(s) = \dfrac12 \left(\dfrac1s + \dfrac{s}{s^2-4}\right) = \boxed{-\dfrac2{s^3-4s}}\)

• (e)

\(t\sinh(2t) \leftrightarrow -F'(s)\)

where F(s) is the Laplace transform of sinh(2t),

\(F(s) = \dfrac{2}{s^2 - 4} \implies -F'(s) = \boxed{\dfrac{4s}{(s^2-4)^2}}\)

• (f)

\(\sin(t) \cos(t) = \dfrac12 \left(2\sin(t) \cos(t)\right) = \dfrac12 \sin(2t)\)

with transform

\(F(s) = \dfrac12 \times \dfrac{2}{s^2+4} = \boxed{\dfrac1{s^2+4}}\)

• (g)

\(\sin\left(t+\dfrac\pi4\right) = \sin(t) \cos\left(\dfrac\pi4\right) + \cos(t) \sin\left(\dfrac\pi4\right) = \dfrac1{\sqrt2} \left(\sin(t) + \cos(t)\right)\)

with transform

\(F(s) = \dfrac1{\sqrt2} \left(\dfrac1{s^2+1} + \dfrac{s}{s^2+1}\right) = \boxed{\dfrac{s+1}{\sqrt2 (s^2+1)}}\)

The last two are trivial and follow directly from the properties listed above.

• (h)

\(\cos(2t) - \cos(3t) \leftrightarrow \dfrac{s}{s^2+4} - \dfrac{s}{s^2+9} = \boxed{\dfrac{5s}{s^4 + 13s^2 + 36}}\)

• (i)

\(\sin(2t) + \cos(4t) \leftrightarrow \dfrac2{s^2+4} + \dfrac{s}{s^2+16} = \boxed{\dfrac{s^3+2s^2+4s+32}{s^4+20s^2+64}}\)
