The value of Z is -27/37. To solve this problem, we will first simplify the expression on the left-hand side of the equation.

Using the distributive property of multiplication, we get:

(4+2n) = 2(2+n)

Next, we will simplify the expression on the right-hand side of the equation. We will use the complex conjugate to get rid of the imaginary part. The complex conjugate of (2+3i) is (2-3i), so we have:

(2+3i)*(2-3i) = 4 + 9 = 13

Now we have:

(4+2n)/(13) = (2+3i) + (3-2i)/(13)

To show that the left-hand side is a real number, we need to show that the imaginary part is equal to zero. We can simplify the right-hand side to get:

(2+3i) + (3-2i)/(13) = 2/13 + 3i/13 + 3/13 - 2i/13

The imaginary part is (3/13 - 2i/13), which is equal to:

(3/13) - (2/13)i

Since the denominator is a positive integer, we can see that the imaginary part is a multiple of (1/i), which is equal to -i. Therefore, the imaginary part is equal to zero, and the left-hand side is a real number.

To find the value of Z, we need to solve for (2n+4)/(13) = 2/13, which gives us n= -1. Substituting this value back into the original equation, we get:

(4+2(-1))/(13) = 2+3i + (3-2i)/(13)

2/13 = 2+3i + (3-2i)/(13)

Multiplying both sides by 13, we get:

2 = 26 + 39i + (3-2i)

Simplifying, we get:

-27 = 37i

Therefore, the value of Z is -27/37.

You would need to wait approximately 51.33 years from now to grow your initial investment of $39,000 to $174,000 at an interest rate of 10% per year.

To calculate the number of periods (years) required to grow an initial investment to a desired future value, we can use the formula for compound interest:

FV = PV * \((1 + r)^n\)

Where:

FV is the future value

PV is the present value (initial investment)

r is the interest rate per period

n is the number of periods

In this case:

PV = $39,000

FV = $174,000

r = 10% per year

Let's calculate the number of periods (years):

FV = PV * \((1 + r)^n\)

174,000 = 39,000 * \((1 + 0.10)^n\)

Divide both sides by 39,000:

4.4615 = \((1.10)^n\)

Take the logarithm of both sides to solve for n:

log(4.4615) = n * log(1.10)

n ≈ log(4.4615) / log(1.10)

n ≈ 2.1270 / 0.0414

n ≈ 51.33 (rounded to two decimal places)

Step-by-step explanation:

x = -b+/- (sq) b^2 - 4ac.

Well the way to plug the numbers in is by using this equation: Ax^2 + Bx + C = 0

S if you use your equation : 3x^2 = 20 - 7x

First you have to move everything to one side.

So it'll look like this:

3x^2 = 20 - 7x

-20      -20

3x^2 - 20 = -7x

+7x  +7x

3x^2 - 20 + 7x = 0

don't forget that... Ax^2 +Bx+ C= 0

3 = A

The length of the diameter is 17.5

A diameter is a line segment that divides a circle into two equal parts.

The diameter is the line of symmetry of the circle and it divides the circle to form semi-circles.

The length of a line segment with end coordinates is calculated using the formula below,

D = \(\sqrt{(x_{2} - x_{1}) ^{2} + (y_{2} -y_{1}) ^{2} }\)

Where, \(x_{2}\) = 6, \(x_{1}\) = -1,  \(y_{2}\) = 21,  \(y_{1}\) = -1

D = \(\sqrt{(6--1)^{2} + (21-5)^{2} }\)

D = \(\sqrt{(7)^{2} + (16)^{2} }\)

D = \(\sqrt{49 + 256}\)

D = \(\sqrt{305}\)

D = 17.5

The equivalent function for a picture x cm by x cm is: A. F3(x) = F2(F1(x)) = 1.2x + 2.

In Geometry, dilation can be defined as a type of transformation which changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased (enlarged) or decreased based on the scale factor used.

20% enlargement = 120/100 = 1.2

For function F1, we have:

Function, F1(x) = 1.2x

For function F2, which increases the picture size by 2 cm in both dimensions is given by:

Function, F2(x) = F1(x) + 2

Next, the transformation from function F3 is given by:

Function, F3(x) = F2(F1(x)) = 1.2x + 2

An unnormalized relation refers to a table in a relational database that contains more than one row. This means that there are duplicate rows in the table, which violates the rules of normalization.

Normalization is a process in database design that aims to eliminate data redundancy and ensure data integrity. It involves breaking down a database into multiple tables and defining relationships between them. By doing so, we can efficiently store and retrieve data while minimizing inconsistencies.

In an unnormalized relation, duplicate rows can lead to various problems. For example, it can result in data inconsistencies, as updating one instance of a row may not reflect changes in other duplicate rows. Additionally, it can cause unnecessary storage and maintenance overhead.

To normalize an unnormalized relation, we need to identify the functional dependencies in the table and create separate tables for related data. This helps organize the data and reduces redundancy.

In summary, an unnormalized relation is a table in a relational database that has duplicate rows. It is important to normalize such relations to ensure data integrity and efficiency.

Step-by-step explanation:

Two questions about systems aaa and bbb, the given system is:

System aaa: x = -1/3 and y = -7/3
System bbb: x = -1/3 and y = -7/3

To answer two questions about systems aaa and bbb, let's first clarify the given system:

System aaa:
x - 4y = 9

System bbb:
2x + y = -3

Question 1: Solve system aaa.
To solve system aaa, we'll use the method of substitution:

Step 1: Solve one equation for one variable.
From the first equation in system aaa, we can isolate x:
x = 4y + 9

Step 2: Substitute the expression from Step 1 into the other equation.
Substitute the expression for x in the second equation of system aaa:
2(4y + 9) + y = -3

Step 3: Simplify and solve for y.
8y + 18 + y = -3
9y + 18 = -3
9y = -3 - 18
9y = -21
y = -21/9
y = -7/3

Step 4: Substitute the value of y into the expression for x.
Using the first equation in system aaa:
x - 4(-7/3) = 9
x + 28/3 = 9
x = 9 - 28/3
x = (27 - 28)/3
x = -1/3

Therefore, the solution to system aaa is x = -1/3 and y = -7/3.

Question 2: Solve system bbb.
To solve system bbb, we'll use the method of substitution:

Step 1: Solve one equation for one variable.
From the second equation in system bbb, we can isolate y:
y = -2x - 3

Step 2: Substitute the expression from Step 1 into the other equation.
Substitute the expression for y in the first equation of system bbb:
x - 4(-2x - 3) = 9

Step 3: Simplify and solve for x.
x + 8x + 12 = 9
9x + 12 = 9
9x = 9 - 12
9x = -3
x = -3/9
x = -1/3

Step 4: Substitute the value of x into the expression for y.
Using the second equation in system bbb:
y = -2(-1/3) - 3
y = 2/3 - 3
y = 2/3 - 9/3
y = -7/3

Therefore, the solution to system bbb is x = -1/3 and y = -7/3.

The answer is yes, (x + 6) is a possible length of a rectangle with area x² + x − 30.

To determine whether (x + 6) is a possible length of a rectangle with area x^² + x − 30, we can use an area model to visualize the situation.

First, we need to find the width of the rectangle.

The area of a rectangle is given by the formula A = lw,

where A is the area, l is the length, and w is the width.

We are given that the area is x² + x − 30, so we can set this equal to lw and solve for w:

x² + x − 30 = (x + 6)w

w = (x² + x − 30)/(x + 6)

The length of a rectangle must be greater than or equal to its width, so we need to check whether (x + 6) is greater than or equal to (x² + x − 30)/(x + 6). This simplifies to:

(x + 6) ≥ x² + x − 30

Expanding the left side and simplifying, we get:

x² + 12x + 36 ≥ x² + x − 30

11x ≥ -66

x ≥ -6

Since x must be a positive number (since we are dealing with lengths), we can conclude that (x + 6) is the possible length of the rectangle. Therefore, the answer is yes, (x + 6) is a possible length of a rectangle with an area x² + x − 30.
