Answer: 4cos(pi/6x)+3

Step-by-step explanation:

1. Cosx = 5/√(41)

2. An equation {tan(x) + cot(x)}/{tan(x)} =csc²(x)

Equations using trigonometric functions that hold true for all possible values of the variables are known as trigonometric identities.

Given:

1. tanx = -4/5

and tanx = perpendicular/adjacent leg

So, P = -4 and A = 5

So, H = √(-4)² + (5)²

H = √(41)

So, Cosx = 5/√(41)

2. A trigonometric identity,

{tan(x) + cot(x)}/{tan(x)}

Simplifying,

= {tan(x)/tan(x) + cot(x)/{1/tan(x)}

= 1 + cot²(x)

= csc²(x)

Therefore, Cosx = 5/√(41)

Completely factorize the polynomial using any methods that are appropriate, then look for shared factors and the polynomial's roots. Next, double-check your work to confirm accuracy.

Follow these steps to determine a polynomial's factorization:

Completely factor the polynomial using any relevant techniques, including grouping, utilizing the difference of squares or cubes, or using the quadratic formula.

By multiplying them all together, you can verify that each factor is accurate. The final figure must match the initial polynomial.

Look for shared factors among the polynomial factors. If the polynomial has common components, remove them from the equation and rewrite it as the product of the common factors and the other factors.

The polynomial's roots can be verified by setting each factor to zero and calculating the variable. The roots ought to correspond to the original polynomial.

Verify your work a second time to make sure all relevant elements have been identified and taken into consideration.

In order to guide learners to move from the concrete level to the semi-concrete and finally to the abstract level in relation to their understanding of the more than/less than concept, I would use a step-by-step approach.

At the concrete level, I would introduce the concept of more than/less than with a hands-on activity. For example, I would have students compare the number of counters or blocks and have them determine which group has more or less. This would help them develop a fundamental understanding of the concept.At the semi-concrete level, I would introduce the concept of more than/less than with written numerals. I would have students compare numbers on paper, such as 4 and 6, and have them determine which number is more or less. I would also ask them to use concrete objects to represent the numbers, such as using four counters for 4 and six counters for 6.At the abstract level, I would introduce the concept of more than/less than with larger numbers. I would ask students to compare numbers such as 12 and 15, and determine which number is more or less. I would also ask them to use abstract symbols, such as 12 + and 15 -, to represent the numbers.By using this step-by-step approach, students will be able to move from the concrete level to the semi-concrete and finally to the abstract level of understanding the more than/less than concept. This will help them develop a strong foundation of the concept, which will allow them to solve more complex problems in the future.

Answer:

Values of x are ±4 and ±5

Step-by-step explanation:

Let y = [tex]x^{2}[/tex]

Which means: [tex]y^{2} = x^{4}[/tex]

Therefore:

A quadratic equation is formed:

[tex]y^{2} - 41y + 400 = 0[/tex]

The above quadratic equation can be simplified either by The Double Bubble Method or using the quadratic formula

Double Bubble Method:

[tex]y^{2} - 41y + 400 = 0[/tex]

The pair of factors of 400 that add together to give 41 are 25 and 16. Use these two factors to rewritre -41y:

[tex]y^{2} - 25y - 16y + 400 = 0[/tex]

Then do Factorization by grouping (i.e group the terms with common factors before factorizing):

[tex]y(y -25) - 16(y - 25) = 0[/tex]

[tex](y - 25)(y - 16) = 0[/tex]

The product of two expressions is zero, which means either of the two expressions is equal to Zero:

Either: [tex]y - 25 = 0[/tex]

Substituting [tex]y = x^{2}[/tex]:

          = [tex]x^{2} - 25 = 0[/tex]

         = [tex]x^{2} = 25[/tex]

         = [tex]\sqrt{x^{2}} = \sqrt{25}[/tex]

         ∴ x = ±5

 Or: [tex]y - 16 = 0[/tex]

Substituting [tex]y = x^{2}[/tex]

     [tex]= x^{2} - 16 = 0[/tex]

     [tex]= x^{2} = 16[/tex]

     [tex]= \sqrt{x^{2}} = \sqrt{16}[/tex]

    ∴ x = ±4

If Elish was required to write a 600 word Literature essay and word count on her computer showed that she had typed 240 words Elish still needs to complete 3/5 of the essay.

To find the fraction of the essay that Elish still needs to complete, we need to determine how many words she has left to write. We can do this by subtracting the number of words she has already written from the total required word count:

Words left to write = Total word count - Words already written

Words left to write = 600 - 240

Words left to write = 360

Now, to find the fraction of the essay that Elish still needs to complete, we can express the remaining words as a fraction of the total word count:

Fraction of essay left to complete = Words left to write / Total word count

Fraction of essay left to complete = 360 / 600

We can simplify this fraction by dividing both the numerator and denominator by their greatest common factor, which is 120:

Fraction of essay left to complete = (360 ÷ 120) / (600 ÷ 120)

Fraction of essay left to complete = 3 / 5

This means that she has completed 2/5 of the essay so far (which is the equivalent fraction of 240/600).

There are two quadratic functions as A. 2b(b - 7) + b = 0 and B. (4a + 2)(2a - 1) + 1 = 0.

The quadratic function is defined as a function containing the highest power of a variable is two.

A. 2b(b - 7) + b = 0 is a quadratic function because it can be simplified to the form of ax² + bx + c = 0 where a, b, and c are constants and x is the variable. In this case, a = 2, b = -13, and c = 0.

B. (4a + 2)(2a - 1) + 1 = 0 is also a quadratic function because it can be simplified to the form of ax² + bx + c = 0. In this case, a = 8, b = -2, and c = 1.

C. 2y + 2(3y - 5) = 0 is not a quadratic function because it can be simplified to the form of mx + b = 0 where m and b are constants and x is the variable.

D. 8 - 5x = 4(3x - 1) is not a quadratic function because it can be simplified to the form of mx + b = 0 where m and b are constants and x is the variable.

Answer:

Step-by-step explanation:

According to the equation, when 9 video games are rented, the total cost is $31.5 which is expressed in the equation as 3.5x.

What is an equation?

A formula known as an equation uses the equals sign (=) to express how two expressions are equal. It demonstrates the equality of the relationship between the expressions printed on the left and right sides. We have left hand side equal to right hand side in every mathematical equation. To determine the value of an unknown variable that represents an unknown quantity, equations can be solved. A statement is not an equation if it has no "equal to" sign. It will be regarded as an expression.

Given,

The cost of renting a video game = $3.50

The total cost of rentals for the month  = $31.50

The equation given is:

    3.5x = 31.5

The term 3.5x in the equation represents the total cost of a month when the number of video games rented is x.

In this case x = 31.5/3.5 = 9

Therefore, according to the equation, when 9 video games are rented, the total cost is $31.5 which is expressed in the equation as 3.5x.

Answer:

10.305

Step-by-step explanation:

The numbers required in the word problem are

Let's call the numbers x and y

From the first equation, we have:

2x + y = 18

From the second equation, we have:

3x - y = 7

Solving simultaneously by substitution method

3x - y = 7

3x = 7 + y

x = (7 + y)/3

substitute this expression for x into the first equation:

2x + y = 18

2((7 + y)/3) + y = 18

14/3 + 3y/3 = 18

14/3 = 18 - 3y/3

14/3 = 18 - y

collecting like terms

y = 18 - 14/3

y = 18 - 4 2/3

y = 13 1/3

substituting to solve for y

x = (7 + y)/3

x = (7 + 13 1/3)/3

x = 10 4/3/3
