What are the 3 types of forecasting?

Transformations. Transform is the verb form of change. Therefore, to modify a geometric shape would entail to make certain changes to that shape.

Transforming something into another thing is referred to by the verbs transform, metamorphosis, transmute, convert, and transfigure. Transform suggests a significant shift in form, nature, or function. To completely and instantly modify something or someone so that they are considerably better or more beautiful is to transform them. When you move into a new home, quit your job, or become a parent, you are experiencing "change."

"Transition" refers to the process that takes place before to, during, and following the change event. We experience transition on a bodily, emotional, and psychological level, and we change as a result. Mathematicians define a transformation as a geometric shape or formula alteration that transfers the shape or formula from its pre-image, or original position, to its image, or after-transformation position.

Kelly's estimate cannot be said to be reasonable because it falls below the range of acceptable number of sunglasses from the given amount in each box.

We are told that Kelly bought 4 boxes.

Now, we are told that each box had either 20, 25, or 30 pairs of sunglasses in it.

Thus;

Minimum number of sunglasses = 20 * 4 = 80 sunglasses

Maximum number of sunglasses = 30 * 4 = 120 sunglasses

Now, we are told that Kelly estimates a reasonable number of sunglasses to be 70.

From our previous calculations, the minimum possible can only be 80 and as such her estimate falls lower and we conclude that it is unreasonable.

Answer: y=14

Step-by-step explanation: y is directly proportional to x, meaning that multiplying x by a certain factor would also multiply y by that same factor. x=5 and y=7. If x changes to 10, it means that x is multiplied by a factor of (10/5) = 2. Therefore, y is multiplied by this same factor (2). As a result, 7*2=14

The required sets of range of the corresponding functions are illustrated in the below solution part.

The range of a function is the set of all possible output values of the function.

To find the range of a function, we need to evaluate the function at every point in its domain and find the set of all possible output values.

For example, we are given the function f(x) = x² - 2x and the domain (-5, -1, 0, 5, 7). To find the range of this function, we need to evaluate it at every point in its domain, which gives us the following values:

f(-5) = (-5)² - 2 × (-5) = 25 + 10 = 35

f(-1) = (-1)² - 2 × (-1) = 1 + 2 = 3

f(0) = (0)² - 2 × (0) = 0

f(5) = (5)² - 2 × (5) = 25 - 10 = 15

f(7) = (7)² - 2 × (7) = 49 - 14 = 35

The range of the function is therefore the set of all possible output values, which are 3, 0, 15, and 35. Therefore, the range of this function is {3, 0, 15, 35}.

We can use the same method to find the range of the other functions in the questions. The ranges of the other functions are:

6) f(x)=x²-2x & Domain= (-5, -1, 0, 5, 7)

Range: {-1, 3, 0, 15, 35}

7) f(x) = -3x+12) & Domain= (-9, -4, 4, 8, 11)

Range: {0, 15, 36, 39, 48}

8) f(x)=x²-(x/2) & Domain = {4, 8, 12, 30)

Range: {2, 30, 102, 942}

9) f(x)= |x-2x & Domain= (-5, -4,-3, 3, 5)

Range: {-4, -3, 0, 3, 4}

10) f(x) = (x²/2) + 30 & Domain = {-4, -2, 6, 8)

The complete and simplified answer to the question what is 7/9 of 45 is 35.

The number above the fraction line is called the numerator and the number below it is called the denominator. To work out the fraction of any number, we first need to convert that whole number into a fraction as well.

Any number can be converted to fraction if you use 1 as the denominator:

45 / 1

So now that we've converted 45 into a fraction, to work out the answer, we put the fraction 7/9 side by side with our new fraction, 45/1 so that we can multiply those two fractions.

All we need to do is convert the whole number to a fraction and then multiply the numerators and denominators.

7 × 45 / 9 × 1 = 315 / 9

In this case, our new fraction can actually be simplified down further. To do that, we need to find the greatest common factor of both numbers.

You can use our handy GCF calculator to work this out yourself if you want to. We already did that, and the GCF of 315 and 9 is 9.

We can now divide both the new numerator and the denominator by 9 to simplify this fraction down to its lowest terms.

315 / 9 = 35

9 / 9 = 1

When we put that together, we can see that our complete answer is:

To solve a system of equations using substitution, you can start by solving one of the equations for one of the variables, such as x or y. For example, in this case, we can solve the first equation for x by subtracting y from both sides, like this:

[tex]-x - y = 1[/tex]
[tex]-x = 1 - y[/tex]

Now that we have an expression for x in terms of y, we can substitute that expression into the second equation to solve for y. When we do that, we get:

[tex]y = -(1 - y) + 4[/tex]
[tex]y = -1 + y + 4[/tex]

Now we can rearrange the terms on the right-hand side to make it easier to solve for y:

[tex]y = y + 4 - 1[/tex]

And when we combine the y terms on the left-hand side, we get:

[tex]2y = 3[/tex]

Finally, we can solve for y by dividing both sides by 2, like this:

[tex]y = 3 / 2[/tex]

Once we know the value of y, we can substitute it back into any of the original equations to solve for the other variable, x. In this case, if we substitute the value of y into the first equation, we get:

[tex]-x - y = 1[/tex]
[tex]-x - (3 / 2) = 1[/tex]

We can solve for x by rearranging the terms on the left-hand side and then dividing both sides by -1, like this:

[tex]-x = -1 + (3 / 2)[/tex]
[tex]x = (1 - 3) / 2[/tex]
Therefore, the solution to the system of equations is x = -1 and y = 3/2.

It's important to check your solution by substituting the values of x and y into the original equations to make sure they work. For example, if we substitute x = -1 and y = 3/2 into the first equation, we get:

[tex](-1) - (3 / 2) = 1[/tex]

And if we substitute the same values into the second equation, we get:

[tex](3 / 2) = (-1) + 4[/tex]

Both of these equations are true, which means our solution is correct.

According to the given statement the width of the walkway (x) is 8 feet.

Four of the sides of a square's two-dimensional form are equal in length. In a square, all four internal angles were right angles, and the opposing sides are parallel to one another. Real-world examples of square-shaped things include floor tiles, tea towels, hexagonal tiles, cheddar cheese, and so on.

Area of a Square = (side)(side)

Total area of the pool and walkway = 506 sq. ft

Length of the pool and walkway = 7 + 2x

Width of the pool and walkway = 6 + 2x

Thus, we will have the equation of the total area as:

(7 + 2x)(6 + 2x) = 506

4x² + 12x + 14x + 42 = 506

4x² + 26x + 42 = 506

4x² + 26x + 42 - 506 = 0

4x² + 26x - 464 = 0

2x² + 13x - 232 = 0

The equation be like;

y - f(a) / (x - a) = f'(a)

y = f'(a) (x - a) + f(a)

Using the provided data and a = 2, we can determine that the tangent line to the graph of y = f(x) at x = 2 has equation
