Answer:

(4x - 9)(3x + 2)(4x - 5)(3x - 1).

Step-by-step explanation:

Let's substitute y = (12x² - 19x):

So we have y² - 13y - 90, which can be factored as:

y² - 13y - 90 = (y - 18)(y + 5)

Substituting y back:

(12x² - 19x)² - 13(12x² - 19x) - 90 = [(12x² - 19x) - 18][(12x² - 19x) + 5]

= (12x² - 19x - 18)(12x² - 19x + 5)

= (4x - 9)(3x + 2)(4x - 5)(3x - 1)

To set the data type of the registerdate field to "date", the syntax would depend on the programming language or database management system being used. However, here are some examples:

In SQL, the syntax would be:

ALTER TABLE tablename MODIFY COLUMN registerdate DATE;

This statement modifies the registerdate column in the tablename table to have a data type of DATE.

In PHP, the syntax for creating a table with a register date column of data type DATE would be:

CREATE TABLE tablename (

   ...,

   registerdate DATE,

   ...

);

This creates a table called tablename with a column called registerdate of data type DATE.

In Python using SQLAlchemy, the syntax for defining a registerdate column of data type Date in a declarative base would be:

from sqlalchemy import Column, Date

class MyTable(Base):

   __tablename__ = 'mytable'

   registerdate = Column(Date)

This creates a MyTable class with a column called registerdate of data type Date.

To set the data type of the registerdate field to "date", the syntax would depend on the specific programming language or database system being used. However, a common syntax to set the data type to "date" is:
registerdate DATE;
This syntax would typically be used in the creation of a table or the declaration of a variable in a programming language that supports date data types.

To identify a syntax that sets the data type of the 'registerdate' field to "date", you can use the following SQL statement:

```sql
CREATE TABLE your_table_name (
   registerdate DATE
);
```

Here's a step-by-step explanation of the syntax:
1. "CREATE TABLE" is the command to create a new table in the database.
2. "your_table_name" should be replaced with the desired name for your table.
3. Within the parentheses, you define the columns and their data types.
4. "registerdate" is the name of the field that you want to set the data type for.
5. "DATE" is the data type you are setting for the 'registerdate' field.

The percent rate of change of students graduating within 4 years from 1995 to 2009 =   8.17%

Here,  the percent of studenst graduated in 1995 = 57. 5%

and the percent of studenst graduated in 2009 = 52. 8%

First we find the relative change.

Let a represents the initial value and b represents the findal value

a =  57.5 and b =  52.8

so, the relative rate of change of students would be,

r = (b - a)/a

r = |(52.8 -  57.5)| /  57.5

r =  0.0817

And the percent rate of change of students graduating within 4 years from 1995 to 2009 would be,

The correct function that defines the area of the rectangle is:

A(z) = 2[tex]x^{2}[/tex]+ 9x + 4 (option A).

The area of a rectangle is given by the product of its length and width. So, the function that defines the area of the rectangle would be:

A(x) = l(x) * w(x)

where l(x) is the length of the rectangle given by the function 1(x) = 2x + 1, and w(x) is the width of the rectangle given by the function w(x) = x + 4.

Substituting the given functions for length and width, we get:

A(x) = (2x + 1) * (x + 4)

Now, we can expand and simplify the expression:

A(x) = [tex]2x^2 + 8x + x + 4[/tex]

A(x) = [tex]2x^2 + 9x + 4[/tex]

The statement "When eliminating a loop-carried dependency that adds a constant, the closed-form direct solution will likely contain a multiplication" is true because eliminating a loop-carried dependency that adds a constant simplifies the equation, but to obtain a closed-form direct solution, we need to express the result as a function of the current iteration's variables only

When eliminating a loop-carried dependency that adds a constant, the closed-form direct solution will likely contain a multiplication. This is because the loop-carried dependency adds a constant to the result of the previous iteration, which means that the current iteration's result is a function of both the current iteration's variables and the previous iteration's result.

By eliminating this dependency, we remove the need to use the previous iteration's result, which simplifies the equation. However, to obtain a closed-form direct solution, we need to express the result as a function of the current iteration's variables only, which often involves a multiplication. This is because multiplication is a fundamental mathematical operation that allows us to combine variables in a way that preserves their individual values.

The total fencing used is 36 ft and the playpen would look like a square rather than a rectangle.

1) The given design uses 36 feet of fencing. Other playpens that could be made with the same amount of fencing are:

A square playpen with sides of length 9 feet (since 4 x 9 = 36)

A rectangular playpen with length 12 feet and width 6 feet (since 2 x (12 + 6) = 36)

2) The fencing used for the given design is the sum of the lengths of all four sides. From the diagram, we can see that the two shorter sides have a length of 8 feet each, and the two longer sides have a length of 10 feet each. Therefore, the total fencing used is:

2(8 ft) + 2(10 ft) = 16 ft + 20 ft = 36 ft

3) Leah's statement is not correct. A square playpen with sides of length 9 feet would require a perimeter of 4 x 9 = 36 feet, which is the same amount of fencing used for the given design. However, the shape of the playpen would be different, since the sides would all be equal in length. The playpen would look like a square rather than a rectangle.

4) Another playpen that could be made with the same amount of fencing is a rectangular playpen with length 18 feet and width 0 feet (i.e., a straight line). The perimeter would be:

The surface area of the figure is derived to be equal to 656.4 square meters.

The top of the figure is a triangular prism, the bottom is a triangle, and the sides are 3 same size rectangles, so the surface area is calculated as follows:

area of one top triangle face = 1/2 × 12 m × 5 m = 30 m²

area of top triangular prism = 3 × 30 m² = 90 m².

area of bottom triangle = 1/2 × 12 m × 10.4 m = 62.4 m²

area of one rectangle side = 14 m × 12 m = 168 m²

area of the three rectangle sides = 3 × 168 m² = 504 m²

surface area of the figure = 90 m² + 62.4 m² + 504 m²

Step-by-step explanation:

Let's use the variables x and y to represent the number of bags of soil and plants, respectively, that Katte will buy.

The cost of x bags of soil is $4x, and the cost of y plants is $10y. Therefore, the total cost of Katte's purchases is:

$4x + $10y

We want to make sure that she doesn't spend more than $100, so we can write:

$4x + $10y ≤ $100

We also want to make sure that she buys at least 5 plants, so we can write:

y ≥ 5

Finally, we want to make sure that both x and y are non-negative, since you can't buy negative bags of soil or plants. Therefore, we can write:

x ≥ 0

y ≥ 0

Putting it all together, the system of linear inequalities is:

4x + 10y ≤ 100

y ≥ 5

x ≥ 0

y ≥ 0

To graph this system, we can start by graphing the boundary lines for each inequality. The boundary for 4x + 10y ≤ 100 is the line 4x + 10y = 100, which we can graph by finding two points on the line:

When x = 0, we have 10y = 100, so y = 10. Therefore, one point on the line is (0, 10).

When y = 0, we have 4x = 100, so x = 25. Therefore, another point on the line is (25, 0).

Plotting these two points and connecting them with a line gives us the boundary for 4x + 10y ≤ 100:

The boundary for y ≥ 5 is the horizontal line y = 5. We can graph this line by plotting two points on the line:

When x = 0, we have y = 5, so one point on the line is (0, 5).

When x = 100/4 = 25, we still have y = 5, so another point on the line is (25, 5).

Plotting these two points and connecting them with a line gives us the boundary for y ≥ 5:

The cost of the envelope and stamp may vary depending on the location and the method of delivery. In this example, we assumed that the cost of the envelope is $0.15 and the cost of the stamp is $0.39, but these values may change based on the specific circumstances.

What is cost?

Cost" is the amount of money or resources that are required to produce, acquire, or obtain something. In other words, cost refers to the expenses that are incurred in the process of acquiring or producing a good or service.

For example, the cost of producing a product may include the cost of raw materials, labor, overhead expenses, and other related costs. Similarly, the cost of acquiring a product may include the purchase price, taxes, shipping costs, and any other fees or expenses associated with the purchase. Overall, cost is a crucial factor in business and economics, as it determines the profitability of a venture and helps to make informed decisions regarding investments and pricing strategies

To find the cost of the laptop after the mail-in rebate and the cost of the envelope and stamp, we can follow these steps:

Subtract the mail-in rebate from the original price of the laptop:

$2,149.99 - $200 = $1,949.99

Add the cost of the envelope and stamp to the cost of the laptop after the mail-in rebate:

$1,949.99 + $0.15 + $0.39 = $2,090.53

Therefore, the cost of the laptop after the mail-in rebate and the cost of the envelope and stamp is $2,090.53.

To explain this calculation, we first subtract the mail-in rebate of $200 from the original price of the laptop, which gives us the price of the laptop after the rebate. Then, we add the cost of the envelope and the stamp to this price to get the total cost of the laptop after the rebate and the cost of the envelope and stamp.

Therefore, The cost of the envelope and stamp may vary depending on the location and the method of delivery. In this example, we assumed that the cost of the envelope is $0.15 and the cost of the stamp is $0.39, but these values may change based on the specific circumstances.

The correct answer is D. Trapezoid EFGH is congruent to Trapezoid ABCD after undergoing transformation D.

Let's first define the transformations:

A. Translation down, followed by rotation of 90°, followed by dilation by a scale factor of 3.

B. Rotation of 45°, followed by a reflection, followed by a translation left.

C. Dilation by a scale factor of 12, followed by a translation up, followed by a reflection.

D. Reflection, followed by a dilation of a scale factor of 1, followed by a rotation of 180°.

To determine if Trapezoid EFGH is congruent to, an enlargement of, or a reduction of Trapezoid ABCD, we need to analyze the effects of each transformation on the trapezoid.

A. Translation down, followed by rotation of 90°, followed by dilation by a scale factor of 3.

This transformation involves moving the trapezoid down, rotating it 90 degrees clockwise, and then increasing its size by a scale factor of 3. This transformation does not preserve angles or side lengths, so Trapezoid EFGH is not congruent to Trapezoid ABCD.

B. Rotation of 45°, followed by a reflection, followed by a translation left.

This transformation involves rotating the trapezoid 45 degrees clockwise, reflecting it across a line of reflection, and then moving it left. This transformation does not preserve angles or side lengths, so Trapezoid EFGH is not congruent to Trapezoid ABCD.

C. Dilation by a scale factor of 12, followed by a translation up, followed by a reflection.

This transformation involves increasing the size of the trapezoid by a scale factor of 12, moving it up, and then reflecting it across a line of reflection. This transformation does not preserve angles or side lengths, so Trapezoid EFGH is not congruent to Trapezoid ABCD.

D. Reflection, followed by a dilation of a scale factor of 1, followed by a rotation of 180°.

This transformation involves reflecting the trapezoid across a line of reflection, then increasing its size by a scale factor of 1 (i.e., not changing its size), and then rotating it 180 degrees. This transformation preserves angles and side lengths, so Trapezoid EFGH is congruent to Trapezoid ABCD.

The only number that is a factor of 63 and 6363 is option B: 3,  while the other options are not factors

A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).

To determine which of the given numbers is a factor of 63 or 6363, we need to check if they divide the given numbers without leaving any remainder.

Option A: 6

63 ÷ 6 = 10 remainder 3

6363 ÷ 6 = 1060 remainder 3

Since both calculations leave a remainder of 3, 6 is not a factor of 63 or 6363.

Option B: 3

63 ÷ 3 = 21

6363 ÷ 3 = 2121

Since both calculations give a whole number without any remainder, 3 is a factor of 63 and 6363.

Option C: 8
