Answers

The equation 6x + 14x - 9 = 4( 5x + 1 ) has no solution.

What is the solution to the given equation?

Given the equation in the question;

6x + 14x - 9 = 4( 5x + 1 )

To solve the equation, first apply distributive property to remove the parenthesis.

6x + 14x - 9 = 4( 5x + 1 )

6x + 14x - 9 = 4 × 5x + 4 × 1

Multiply 4 and 5x

6x + 14x - 9 = 20x + 4 × 1

Multiply 4 and 1

6x + 14x - 9 = 20x + 4

Next, collect and add like terms.

Subtarct 20x from both sides

6x + 14x - 20x - 9 = 20x - 20x + 4

6x + 14x - 20x - 9 =  4

Add 9 to both sides

6x + 14x - 20x - 9 + 9 =  4 + 9

6x + 14x - 20x =  4 + 9

20x - 20x =  4 + 9

20x - 20x =  13

0 = 13

Therefore, there is no solution to the equation.

Answers

The two zeros of the equation are -3,8.

What are zeros?

The zeros of any equation lie on the x axis.On x axis y=0.The zeros can be found by substituting y=0 and finding the corresponding y values.

here, we have,

The given equation is :

f(x) = x² - 5x - 24

Comparing it with quadratic equation

y = ax^2+bx+c

We have a=1,b=-5,c=-24.

To find the zeros we substitute y=0.

x² - 5x - 24= 0

WE need to find two numbers which on multiplication will give us ac that is 1(-24)=-24.The same numbers on addition should give us b=-5.

The two numbers are -8 and 3.-8 times 3=-24 and -8+3=-5.

The factors of the equation are (x+8)(x-3)=0

making  both factors =0 we have:

x+8=0 and x-3=0

Solving for x

x=-8 and x=3.

What is the golden ratio of Fibonacci?

Answers

The golden ratio of Fibonacci, also known as the divine proportion, golden mean, or golden section, is a mathematical constant that is approximately equal to 1.618033988749895.

It is represented by the Greek letter phi (φ) and is found by dividing a line into two parts so that the longer part divided by the smaller part is also equal to the whole length divided by the longer part.

In mathematical terms, the golden ratio is expressed as:

φ = (1 + √5) / 2

The golden ratio is closely related to the Fibonacci sequence, which is a series of numbers where each number is the sum of the two preceding ones, usually starting with 0 and 1. The ratio of consecutive numbers in the Fibonacci sequence converges to the golden ratio as the sequence progresses.

For example, the first few numbers in the Fibonacci sequence are:

0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ...

As we divide each number by the one before it, we get closer and closer to the golden ratio:

1/1 = 1

2/1 = 2

3/2 = 1.5

5/3 = 1.666...

8/5 = 1.6

13/8 = 1.625

21/13 = 1.615...

34/21 = 1.619...

55/34 = 1.617...

89/55 = 1.618...

144/89 = 1.618...

Answers

Noel delivered an average of 500 yards of ribbon per day from Tuesday to Monday.

The central value represents the typical or average value of all the numbers in the set.

From Tuesday to Friday, Noel delivered 350 yards of ribbon per day, a total of 4 days. So, the total length of ribbon that he delivered during this period is

=> 4 * 350 = 1400 yards.

expressions that are tested by the if statement are called ______

Answers

Expressions that are tested by the 'if' statement is called conditions.

A condition is an expression that evaluates to either 'True' or 'False', and it determines whether the code block within the 'if' statement is executed. The 'if' statement allows the program to make decisions and execute different codes based on whether the condition is 'true' or 'false'. For example, in Python, an 'if' statement might look like this:

if x > 10:

   print("x is greater than 10")

In this example, the condition being tested is 'x > 10', which will evaluate as 'True' or 'False' depending on the value of x. If the condition is 'True', then the code block within the 'if' statement (in this case, the print statement) will be executed. If the condition is 'False', then the code block within the 'if' statement will be skipped.

How do you find eigenvalues and eigenvectors on a calculator?

Answers

Eigenvalues and eigenvectors can be found using a calculator by solving the equation Ax = λx, where A is a matrix, x is the eigenvector, and λ is the eigenvalue.

To solve this equation, you first need to calculate the determinant of the matrix A, which is written as |A|. If the determinant is not equal to zero, then you can calculate the eigenvalue by dividing the trace of the matrix (the sum of the diagonal elements) by the number of rows or columns of the matrix. The eigenvalues can then be substituted into the equation to solve for the corresponding eigenvector. For example, for a 2x2 matrix A, the eigenvalues can be found by calculating |A| and then solving the equation λ^2 - (trace of A) * λ + |A| = 0. The eigenvectors can then be found by plugging the eigenvalues into the equation Ax = λx and solving for x.

The surface area of the given cylinder is given by the equation:

    SA =  2π (1.6)² + 3.2π(3.8) square feet

What is meant by a cylinder?

One of the most fundamental curvilinear geometric shapes, a cylinder has historically been a three-dimensional solid. It is regarded as a prism with a circle as its base in basic geometry. One of the fundamental three-dimensional shapes in geometry is the cylinder, which has two distant, parallel circular bases. At a predetermined distance from the centre, a curved surface connects the two circular bases. The axis of the cylinder is the line segment connecting the centres of two circular bases. The height of the cylinder is defined as the distance between the two circular bases.

The surface area of the cylinder is the sum of the area of the curvilinear surface and the areas of the top and bottom circular bases.

Now the area of the curved surface  = 2πrh

Area of bases = πr² + πr² = 2πr²

where,

  r = radius of the cylinder

   h = height of the cylinder

Given,

 r = 3.2 / 2 = 1.6 feet

h = 3.8 feet

Substituting,

Surface area SA = 2πrh + 2πr² = 2π * 1.6 * 3.8 + 2π (1.6)²

                                                =  2π (1.6)² + 3.2π(3.8) square feet.

Therefore the surface area of the given cylinder is given by,

let abc~def and the ratio of the respective altitude is 1:3. if the measure of the sides of abc are 3cm,5cm,and 7cm. Then find the measures of the sides of the larger triangle.

Answers

Answer:

Since the ratio of the altitudes of the two triangles ABC and DEF is 1:3, we can say that the altitude of triangle DEF is three times that of triangle ABC.

Let's assume the altitude of triangle ABC is h, then the altitude of triangle DEF is 3h.

Now, we know that the area of a triangle is given by the formula:

Area = (1/2) * base * height

Let's apply this formula to both triangles:

Area of triangle ABC = (1/2) * base * altitude

= (1/2) * 7cm * h

= 3.5h cm^2

Area of triangle DEF = (1/2) * base * altitude

= (1/2) * 7cm * 3h

= 10.5h cm^2

Since the two triangles are similar, their areas are proportional to the squares of their corresponding sides. That is:

Area of triangle ABC / Area of triangle DEF = (AB / DE)^2

Substituting the values, we get:

3.5h / 10.5h = (AB / DE)^2

1/3 = (AB / DE)^2

Taking the square root of both sides, we get:

AB / DE = 1 / sqrt(3)

AB = (1 / sqrt(3)) * DE

Now, we know that the sides of triangle ABC are 3cm, 5cm, and 7cm.

Let's assume that the sides of triangle DEF are a, b, and c.

Since the sides of the two triangles are proportional, we can write:

a / 3 = b / 5 = c / 7 = 1 / sqrt(3)

Solving for a, b, and c, we get:

a = 3 / sqrt(3) = sqrt(3) cm

b = 5 / sqrt(3) = (5 * sqrt(3)) / 3 cm

c = 7 / sqrt(3) = (7 * sqrt(3)) / sqrt(3) = 7 cm

Therefore, the measures of the sides of triangle DEF are sqrt(3) cm, (5 * sqrt(3)) / 3 cm, and 7 cm.

The system of equations that has a solution of approximately (1.8, –0.9) are: x+2y=0 and 6x-5y=15

What is equation?

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

Here, we have,

we are given the following equations:

i) x-2y= 4

ii) 4x+5y= 8

iii) 6x-5y=15

iv) x+2y=0

Required:

Which system of equations has a solution of approximately (1.8, –0.9).

To find the approximate equations, substitute x and y for  1.8 and  -0.9 into all the equations respectively and check the resulting values

i) Substitute (1.8, -0.9) in x-2y= 4:

1.8 - 2(-0.9) = 4.

1.8 + 1.8 = 4.

3.6 ≠ 4.

ii) Substitute (1.8, -0.9) in 4x+5y= 8

4(1.8) + 5(-0.9) = 8

7.2 - 4.5 = 8.

2.7 ≠ 8.

iii) Substitute (1.8, -0.9) in 6x-5y=15

6(1.8) - 5(-0.9) = 15.

10.8 + 4.5 = 15

15.3 ≠ 15.

This equation has a solution that is close, therefore it is correct.

iv) Substitute (1.8, -0.9) in x+2y=0

1.8 + 2(-0.9) = 0.

1.8 - 1.8 = 0.

0 = 0.

x + 2 y = 0 has the exact value, therefore it is also correct.

The system of equations that has a solution of approximately (1.8, –0.9) are: x+2y=0 and 6x-5y=15

How do you write an inequality in a word problem?

Answers

To indicate that one value is greater than, less than, or equal to another, an inequality in a word problem is written using mathematical symbols like, >, or.

Determine the values that the inequality will compare before using the correct mathematical symbol to express the relationship between them in a word problem. Once the values have been determined, represent the relationship between them using the proper mathematical symbol. For instance, the inequality would be phrased as "x > 5" if the problem stated that "x is greater than 5". Other possible symbols for inequalities are (less than), (less than or equal to), and (more than) (greater than or equal to). It is crucial to always use the appropriate mathematical symbols when creating an inequality since they are needed to indicate the direction of the comparison. Moreover, make sure to incorporate all essential components, including the values being compared, the mathematical symbol, and the equals sign, if required. These procedures can be used to effectively write an inequality in a word problem.
