Which x-value is in the domain of the function f (x) = 4cot(2x) + 3?

0
pi over 3
pi over 2
π

Answers

Answer 1

Answer: pi/3

Step-by-step explanation:

All of the other answers are asymptotes of the function, which by definition means they are not included in the domain, because they are undefined in the domain at that point. If you graph the function and graph all of those x values, you will see that (pi/3) is the only line that crosses the function.

Also, I took the test and got it right.

Answer 2

Only the value of x , [tex]\frac{\pi }{3}[/tex] is in the domain of the function.

What is domain of a function?

The domain of a function is the set of values that we are allowed to plug into our function which makes the function defined.

What are the trigonometric functions?

The trigonometric functions are also called the angle functions, which relates the angles and the ratios of the sides of a right angle triangle.

According to the given question.

We have a trigonomtery function.

[tex]f(x) = 4cot(2x)+3[/tex]

The above trigonometry function can be written as

[tex]f(x) = 4\frac{cos(2x)}{sin(2x)} + 3[/tex]

For the function to be defined the denominator can't be zero.

[tex]sin(2x) \neq 2n\pi ( n \in0, 1, 2, 3, ..)[/tex]

Therefore, from the given values for the x we can only put [tex]\frac{\pi }{3}[/tex] in the given function because [tex]\frac{\pi }{2}[/tex] makes the denominator o which makes the function undefined. Similarly for the π also.

Hence, only the value of x , [tex]\frac{\pi }{3}[/tex] is in the domain of the function.

A school is arranging a field trip to the zoo. The school spends 737.38 dollars on passes for 44
students and 2 teachers. The school also spends 393.36 dollars on lunch for just the students.
How much money was spent on a pass and lunch for each student?

Answers

Step-by-step explanation:

since there is no other information, we have to assume that the prices for student passes and teacher passes are the same.

therefore, the pass price per person is

$737.38 / (44 + 2) = $737.38 / 46 = $16.03

and the lunch costs per student are

$393.36 / 44 = $8.94

altogether,

$16.03 + $8.94 = $24.97

was spent for each student.

The reason why we learn geography in 5th grade is to prepare us for 6th grade geography. The reason why we learn geography in 6th grade is because Geography helps us understand basic physical systems that affect everyday life.

You are choosing between two different cell phone plans. The first plan charges a rate of
21 cents per minute. The second plan charges a monthly fee of $44.95 plus 11 cents per
minute. How many minutes would you have to use in a month in order for the second
plan to be preferable?

Answers

Answer:

at least 450 minutes

Step-by-step explanation:

Find an expression for the cost of each plan as a function of the number of minutes. Set the expressions equal to each other, and solve for the number of minutes.

Let x = number of minutes.

First plan:

cost (in dollars) = 0.21x

Second plan:

cost (in dollars) = 0.11x + 44.95

Set the expressions equal:

0.21x = 0.11x + 44.95

Subtract 0.11x from both sides.

0.1x = 44.95

Divide both sides by 0.1

x = 44.95/0.1

x = 449.5

Since you cannot have a fraction of a minute, the answer is 450 minutes.

The product of the length of 2 unequal poles before cutting 2 cm from each was 285 cm. Their present sum after cutting 2cm from each is 30cm. What is the length of the shorter pole? The product of the length of 2 unequal poles before cutting 2 cm from each was 285 cm . Their present sum after cutting 2cm from each is 30cm . What is the length of the shorter pole ?​

Answers

Answer:

15 cm

Step-by-step explanation:

The length of the shorter pole can be found by forming and subsequently solving 2 equations.

Start by defining the variables that are going to be used in the working.

Let the original length of the shorter pole be a cm and that of the longer pole be b cm.

'Product' refers to the multiplication operation.

ab= 285 -----(1)

On the other hand, 'sum' refers to the addition operation.

Length of shorter pole after cutting= a -2

Length of longer pole after cutting= b -2

(a -2) +(b-2)= 30

a +b -4= 30

Adding 4 to both sides:

a +b= 30 +4

a +b= 34 -----(2)

From (2):

a= 34 -b -----(3)

Let's solve by substitution:

Substitute (3) into (1):

b(34 -b)= 285

Expand:

34b -b²= 285

b² -34b +285= 0

Factorise:

(b -15)(b -19)= 0

b -15= 0       or       b -19= 0

b= 15            or             b= 19

Substitute into (1):

a(15)= 285       or       a(19)= 285

a= 285 ÷15      or             a= 285 ÷19

a= 19                or             a= 15

Since a <b, a= 15 and b= 19.

Thus, the length of the shorter pole is 15 cm.

Slope of the given data is 579.88

What is Slope?

The slope of a line is defined as the change in y coordinate with respect to the change in x coordinate of that line.

Here, given data;

            x₁ = 2009                   y₁ = 12078 burger

            x₂ = 2017                    y₂ = 16717 burger

Now, Slope = (y₂ - y₁)/(x₂ - x₁)

         Slope = (16717 - 12078) / (2017 - 2009)

         Slope = 4639 / 8

The solution to the equation x = 4 + (x + 4) is 0.

The correct option is "one real solution".

What is an equation?

Two algebraic expressions having the same value and symbol '=' in between are called an equation.

Expanding the expression on the right-hand side, we have:

x = 4 + (4x - 4)

x = 4x

Subtracting 4x from both sides, we get:

x - 4x = 0

-3x = 0

Dividing both sides by -3, we get:

x = 0

Therefore, there is one solution to the equation x = 4 + (4x - 4) as the equation simplifies to 0.

So the correct answer is 0, "one real solution".

Think about it like this. For each daisy (1$), the price is double for roses (2$).

Brad has a limit of 33$. And he bought 3 more daisies than roses.

If each daisy is 1$, and he bought 3+ over roses, take away 3$ to get 30$. If he bought 10 (excluding 3+) Daisies, He must have bought 10 roses.

Step-by-step explanation:

To find expected value, you simply multiply the value of each outcome (the numbers in the left column) by its probability

(the numbers in the right column) and then add them all together.

0(0.7) + 1(0.2) + 2(0.05) + 3(0.05)

0 + 0.2 + 0.1 + 0.15 = 0.3 + 0.15 = 0.45

The expected value is 0.45. Thus, the correct option is G.

What is the expected value?

In parameter estimation, the expected value is an application of the weighted sum. Informally, the expected value is the simple average of a considerable number of individually determined outcomes of a randomly picked variable.

The expected value is given below.

E(x) = np

Where n is the number of samples and p is the probability.

The expected value is calculated as,

E(x) = 0 x 0.70 + 1 x 0.20 + 2 x 0.05 + 3 x 0.05

E(x) = 0 + 0.20 + 0.10 + 0.15
