What are trigonometric functions?

Trigonometric functions are also known as Circular Functions can be simply defined as the functions of an angle of a triangle. It means that the relationship between the angles and sides of a triangle are given by these trigonometric functions. The basic trigonometric functions are sine, cosine, tangent, cotangent, secant and cosecant.

The angles of sine, cosine, and tangent are the primary classification of functions of trigonometry. And the three functions which are cotangent, secant and cosecant can be derived from the primary functions.

Now,

given function is csc^2x(1-cos^2x)=1

=csc^2x(sin^2x)

=1/sin^2x*sin^2x

The total population of the wolves after 2 years will be 500 + 125 = 625 wolves

How can we prove it ?

a) After 1 year, the number of wolves in the forest will increase by 25% of the current population, which is 400 wolves.

The increase in population is equal to 0.25 * 400 = 100 wolves

The total population after 1 year will be 400 + 100 = 500 wolves

b) After 2 years, the number of wolves in the forest will increase by 25% of the population from the previous year, which is 500 wolves.

The increase in population is equal to 0.25 * 500 = 125 wolves

The total population after 2 years will be 500 + 125 = 625 wolves

What is percentage ?

What is a linear equation?

When an algebraic equation is graphed, it always results in a straight line since each term in a linear equation has an exponent of 1. For this reason, it is referred to as a "linear equation."

There are both one-variable and two-variable linear equations.

Given In a certain year there were 96 female officials in Congress which is comprised of the house of reps and the Senator

total female members = 96

let the number of female senators be x,

and there were 48 more female members of the house of reps than female senators,

then the number of females representatives = 48 + x

according to condition

x + 48 + x = 6

2x = 96 - 48

x = 48/2

x = 24

the number of female senators = 24

the number of females representatives = 48 + x

the number of females representatives = 48 + 24 = 72

Hence, female senators, are 24 and female representatives are 72.

The factor by which g([tex]x[/tex]) grows over the interval from 14 to 16 is 1.1429.

Whar is factor?

The factor is a number that can be divided evenly into another number. For example, 2, 3, 5 and 10 are all factors of 10. When two or more numbers are multiplied together, each number is a factor of the product.

The factor by which g(x) grows over the interval from 14 to 16 can be determined by calculating the ratio of the values of g(x) at the endpoints of the interval.

At x = 14, g(x) = 4(14) = 56

At x = 16, g(x) = 4(16) = 64

The factor by which g(x) grows over the interval from 14 to 16 is 64/56 = 1.1429.

This means that g(x) grows by a factor of 1.1429 over the interval from 14 to 16.

Annual salary of 55,000 manat from state enterprise. Calculate income tax amount

Answers

The individual entrepreneur's income tax amount is 30,000 manat.

To calculate the income tax amount for an individual entrepreneur in Azerbaijan, we need to first calculate their total taxable income for the year.

Based on the information provided, their total taxable income for the year is calculated below.

40,000 + 30,000 + 25,000 + 55,000 = 150,000 manat.

Next, we need to determine the applicable tax rate based on their taxable income. According to the tax laws in Azerbaijan, the tax rate for individuals with a taxable income of up to 120,000 manat is 20%. For income between 120,000 manat and 200,000 manat, the tax rate is 25%, and for income exceeding 200,000 manat, the tax rate is 30%.

Since the individual's taxable income is 150,000 manat, the applicable tax rate is 20%. Therefore, their income tax amount is 150,000 × 20% = 30,000 manat.

• which one do I put by number line?

Answers

Answer: x ≤ -6 or x > 5

Step-by-step explanation: There are 2 lines so you will need 2 inequalities to define it.

The first line is going to left means the variable (x) will have to be less than the greatest value of the line (the right most point) which is -6. Therefore, x < 6 with < representing less than. However, we also have to consider the a CLOSED dot at -6 meaning the sign of the inequality is going to be ≤ since we including that point in the inequlity saying x can be equal to or less than 6.

The second line going to the right means x has to be greater than the smallest value of the line which is -5 (the left most point of the line). Therefore, x > 5 (> means greater than). In this case, we do not use ≥ because the point at -5 has a OPEN dot meaning x cannot equal 5 and we can not include that point in our inequality so it would just be x > 5.

So we get x ≤ -6 or x > 5

The city will have (blank) streetlights at the end of 49 weeks.
The city will have 191 streetlights at the end of (blank) weeks.

Answers

The solution to the equations are

a) The city will have 231 streetlights at the end of 49 weeks

b) The city will have 191 streetlights at the end of 29 weeks

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

The initial number of streetlights in the city = 133 streetlights

The number of streetlights installed per week = 2 streetlights

So , the number of streetlights after 49 weeks = 49 x number of streetlights installed per week

Substituting the values in the equation , we get

The number of streetlights after 49 weeks = 49 x 2 = 98 streetlights

And , the total number of streetlights after 49 weeks = initial number of streetlights in the city + number of streetlights after 49 weeks

Substituting the values in the equation , we get

The total number of streetlights after 49 weeks A = 133 + 98

The total number of streetlights after 49 weeks A = 231 streetlights

Now ,

Let the number of streetlights after n weeks = 191 streetlights

So , the number of weeks n = ( 191 - initial number of streetlights ) / 2

Substituting the values in the equation , we get

The number of weeks n = ( 58 ) / 2

The number of weeks n = 29 weeks

Hence , the equations are solved

As per college records, the probability of a student taking a chemistry course is 0.40, the probability to take an Arabic course is 0.55, and the probability of taking both courses is 0.15. Which of the following is true?


1- "Taking Chemistry" and "Taking Arabic" are independent but not mutually exclusive events.


2- "Taking Chemistry" and "Taking Arabic" are independent and mutually exclusive events.


3- "Taking Chemistry" and "Taking Arabic" are mutually exclusive but not independent events.


4- "Taking Chemistry" and "Taking Arabic" are neither mutually exclusive nor independent events.

Answers

The correct option is 3-"Taking Chemistry" and "Taking Arabic" are mutually exclusive but not independent events.

Mutually exclusive events are events that cannot happen at the same time, meaning P(A and B) = 0. In this case, P(Taking Chemistry and Taking Arabic) = 0.15, so the events are not mutually exclusive.

Independent events are events where the occurrence of one event does not affect the occurrence of another event, meaning P(A and B) = P(A) * P(B). In this case, P(Taking Chemistry and Taking Arabic) ≠ P(Taking Chemistry) * P(Taking Arabic) = 0.40 * 0.55 = 0.22, so the events are not independent.

The momentum and kinetic energy of an object of mass 5 km moving at speed of 10 m/s are given respectively as

Answers

The momentum of an object is 50 kg m/s and the kinetic energy of an object is 250 Joules.

Describe kinetic energy and momentum of an object.

In contrast to momentum, which is an object's size in motion, kinetic energy is the energy that any material has as it speeds. The relationship between kinetic energy and momentum exists because of how they relate to mass and velocity.

By using the following formula:

Momentum = mass x velocity, we will find the momentum of an object.

Substituting the values of mass and velocity,

Momentum = 5 km x 10 m/s

Momentum = 50,000 kg m/s

Kinetic energy = ½ x mass x (velocity)2

Kinetic Energy = ½ x 5 km x (10 m/s)2

Kinetic Energy = 250 J

Two trains,Train A and train B, weigh a total of 200 tons. Train A is heavier than Train B. The difference of their weights is 4 tons. What is the weight of each train?

Answers

weight of Train A = 102 tons

weight of Train B = 98 tons.

This can be solved using the concept of equation.

What is an equation?

The connection between the two expressions on each side of the sign is represented by a mathematical equation. One variable and an equal sign are often present.

Let, weight of of Train A = x

Weight of Train B = y

So, Train A and train B, weigh a total of 200 tons:

x + y = 200 ...... (1)

The difference of their weights is 4 tons:

x - y = 4 ........ (2)

Solving the both equation, we get-

2x = 204

or, x = 102

thus, y = 200 - x

or, y = 200 - 102

y = 98

Thus, weight of Train A = 102 tons

weight of Train B = 98 tons

when you refer to the meer-kitty survey feedback tab, you are pleased to find that the available data is aligned to the business objective. however, you do some research about confidence level for this type of survey and learn that you need at least 120 unique responses for the survey results to be useful. therefore, the dataset has two limitations: first, there are only 40 responses; second, a meer-kitty superfan, user 588, completed the survey 11 times. as the survey has too few responses and numerous duplicates that are skewing results, you should remove the duplicates and continue analyzing the remaining 29 responses.

Answers

The meer-kitty survey feedback tab has limitations in its data. The survey results must have at least 120 unique responses to be considered useful and aligned with the business objective. The current data, however, only has 40 total responses, with 11 of them coming from one user. This skews the results and makes it difficult to accurately analyze the feedback.

To address these limitations, it is recommended to remove the duplicates, in this case the 11 responses from one user, and focus on the remaining 29 unique responses. This will provide a clearer picture of the survey results and a more accurate representation of the feedback. By doing so, the analysis of the data will be better aligned with the original business objective and provide more valuable insights.

It is important to consider the limitations of the data when conducting any type of analysis, especially when it comes to surveys and feedback. By taking the necessary steps to ensure the data is as accurate and reliable as possible, the results of the analysis will be more meaningful and relevant to the business.
