Therefore, the integral of xtan²(7x) dx is (1/7)tan(7x) + (1/2)x² + C.

The integral of xtan²(7x) dx can be evaluated as follows:

Let's rewrite tan²(7x) as sec²(7x) - 1, using the identity tan²(θ) = sec²(θ) - 1:

∫xtan²(7x) dx = ∫x(sec²(7x) - 1) dx.

Now, we can integrate term by term:

∫x(sec²(7x) - 1) dx = ∫xsec²(7x) dx - ∫x dx.

For the first integral, we can use a substitution u = 7x, du = 7 dx:

∫xsec²(7x) dx = (1/7) ∫usec²(u) du

= (1/7)tan(u) + C1,

where C1 is the constant of integration.

For the second integral, we can simply integrate:

∫x dx = (1/2)x² + C2,

where C2 is another constant of integration.

Putting it all together, we have:

∫xtan²(7x) dx = (1/7)tan(7x) + (1/2)x² + C,

where C = C1 + C2 is the final constant of integration.

The term that is not revealed on a scatter plot is missing data values due to nonresponses.

Scatter plot is a graphical representation of two-dimensional data, where each point on the plot represents a pair of observed (xi, yi ) data values.

This plot can be used to examine the relationship between two continuous variables or to detect unusual data values (outliers). Nonlinear relationships between X and Y can also be revealed on a scatter plot.

An outlier is a data point that significantly differs from the rest of the data, while missing data values due to nonresponses cannot be revealed on a scatter plot since there is no data to plot. Therefore, missing data values due to nonresponses is the term that is not revealed on a scatter plot.

Step-by-step explanation:

Perimeter is the length of all sides added together

2(2x + 3) + 2(5x-1)

4x + 6 + 10x - 2

14x + 4

Answer:

Perimeter = 14x + 4 ⇒ 2 ( 7x + 2 )

Step-by-step explanation:

We know that the opposite sides of a parallelogram are equal to each other.

Therefore, to find the perimeter of the parallelogram you have to add the four sides together.

Perimeter = 2 ( 2x + 3 ) + 2 ( 5x - 1 )

Now let us solve the expression.

2 ( 2x + 3 ) + 2 ( 5x - 1 )

First, solve the brackets.

The value of the expression 9 + (20 x one-fourth) – 6 ÷ 2  is 11.

What is PEMDAS?

PEMDAS stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right). It is a mnemonic or acronym used to remember the order of operations when simplifying mathematical expressions.

Using PEMDAS (Order of Operations), we perform the operations in the following order:

Parentheses

Exponents

Multiplication and Division (from left to right)

Addition and Subtraction (from left to right)

Applying this to the given expression:

9 + (20 x one-fourth) – 6 ÷ 2

= 9 + (20 x 0.25) - 3 [simplify division first: 6 ÷ 2 = 3]

= 9 + 5 - 3 [simplify multiplication: 20 x 0.25 = 5]

= 11 [simplify addition and subtraction from left to right]

Therefore, the value of the expression is 11.

Answer:
The length of the rectangle is 80 cm.

What is circumference ?
Circumference is the distance around the edge of a circle. It is the total length of the boundary of a circle. In other words, it is the perimeter of the circle.

\(C=2\pi r\)
where r is the radius of the circle

Step-by-step explanation:
Let's start by using the given information about the wire and the circle. The circumference of a circle is given by the formula:

C=2πr
where C is the circumference and r is the radius of the circle.
We are given that the circumference of the circle made by the wire is 176 cm, so we can write:

176 = 2πr

Simplifying this equation, we get:

r = 88/π

Now, when the wire is cut and made into a rectangle, the length of the wire is equal to the perimeter of the rectangle. The perimeter of a rectangle is given by the formula:

P = 2(l + b)

where P is the perimeter, l is the length, and b is the breadth of the rectangle.

We are given that the breadth of the rectangle is 8 cm, so we can write:

P = 2(l + 8)

But we also know that the length of the wire is equal to the circumference of the circle, which we found to be 176 cm. So we can write:

P = 176

Substituting this into the previous equation, we get:

176 = 2(l + 8)

Simplifying this equation, we get:

l + 8 = 88

l = 80

Therefore, the length of the rectangle is 80 cm.

Answer:

f ( 5 x + 2 ) = 15 x + 5

Step-by-step explanation:

Answer:

TRUE

Step-by-step explanation:

Angle <A and angle <B are complementary, which means their sum must be = 90

Angle <B and angle <C are supplementary which means their sum must be = 180

Now let's see

m∠A=3x+17, m∠B=55−x, and m∠C=67(x/3−1)

first find the sum of A and B

3x + 17 + 55 - x = 90 add like terms

2x + 72 = 90 subtract 72 from both sides

2x = 18 divide both sides by 2

x = 9

TRUE OR FALSE is asked for

m∠A=44, m∠B=46, and m∠C=134

to find that we just replace c with 9 with every expression given for angles

m<A = 3x + 17

m<A = 3*9 + 17 = 44

m<B =  55 - x

m<B = 55 - 9 = 46

m<C = 134, we don't really need to calculate one by one since the angle are complementary and supplementary.

The answer is TRUE

The statement is true if A and ∠B are complements, while ∠B and ∠C are supplements.

When two lines or rays converge at the same point, the measurement between them is called a "Angle."

We have:

∠A and ∠B are complements, while ∠B and ∠C are supplements.

∠A + ∠B = 90 degree

3x + 17 + 55 - x = 90

2x = 18

x = 9

Angle ∠B and angle ∠C are supplementary:

∠B + ∠C = 180

55 -x + 67(x/3  - 1) = 180

x = 9

Put the value of x and find angles A, B, and C.

m∠A = 44

m∠B = 46

m∠C = 134

∠A + ∠B = 90

∠B + ∠C = 180

The above statement is true.

Thus, the statement is true if A and ∠B are complements, while ∠B and ∠C are supplements.

Answer: 19 units squared

Step-by-step explanation:

1) Use Area= 1/2bh to get the area of the two triangles, 15 and 4

2) Add the areas together

Answer:

19 units squared

Step-by-step explanation:

I have attached an image that explains the process.

Essentially we split the shape into 3 triangles, and solve the area of each, and add them up.

The top right triangle is 3 x 5. So A = (3 x 5) / 2 = 7.5

The bottom right triangle is a copy of the top right. So that A = 7.5

The triangle on the left is 4 long and 2 high. So A = (4 x 2) / 2 = 4 units.

Total area is:

7.5 + 7.5 + 4 = 19 units squared.

This measure of central tendency can be considered the most precise in option c. mean

The mean is a measure of central tendency that calculates the average of a set of values. It is often considered the most precise measure because it takes into account all the values in the dataset and provides a balanced representation.

The mean is calculated by summing all the values and dividing by the total number of values. Unlike the mode, which only identifies the most frequently occurring value, and the median, which represents the middle value, the mean incorporates all the values and provides a comprehensive summary of the dataset.

However, it is important to note that the mean can be sensitive to extreme values or outliers in the data.

To determine which outcome is more likely, we need to consider the probability of each outcome occurring.

(i) The sequence (2 2 2 2 2 2 2 2 2 2 2 2) consists only of the number 2. Since each roll of the fair die has 6 possible outcomes (numbers 1 to 6), the probability of getting a sequence consisting only of 2s is (1/6)^12, which is extremely low but not absolutely impossible.

(ii) The sequence (1 1 2 2 3 3 4 4 5 5 6 6) consists of two of each number from 1 to 6. There are 12!/(2!2!2!2!2!2!) possible arrangements of these numbers, which is much larger than the probability of getting sequence (i).

(iii) The sequence (4 6 2 1 3 5 2 6 4 3 1 5) is a random arrangement of the numbers 1 to 6. Similarly to (ii), there are 12!/(2!2!2!2!2!2!) possible arrangements.

Answer:

  see below

Step-by-step explanation:

The cost for purchase of 0 tokens is $60. This "initial value" is the y-intercept of the function.

The cost for each token is $1.00/10 = 1/10 (dollar), so the slope of the function is 1/10.

The slope-intercept form of the function can be written ...

  y = mx + b . . . . . for slope m and y-intercept b

  y = 1/10x + 60

__

The minimum value of this function is 60, so the range is y ≥ 60.

The function is defined for all real numbers, but only makes sense for all non-negative integers. So, we cannot claim the domain is all real numbers.

Answer:

(B, C, E)

Step-by-step explanation:

Let's evaluate each answer choice:

"The slope of the function is $1.00"

Wrong. The slope is how much one game token costs. It costs $1 per 10 tokens, not 1 token. To find the cost of 1 game token, you would divide 1 by 10, giving you a value of 1/10.

"The y-intercept of the function is $60"

Correct. The initial fee is $60, and this initial fee doesn't change, so it's the y-intercept.

"The function can be represented by the equation y = 1/10x + 60"

Correct. We just mentioned before that the slope is 1/10 and the y-intercept is 60.

"The domain is all real numbers"

Wrong. "All real numbers" also includes negative numbers. However, x represents the number of tokens bought, and you can't buy a negative amount of tokens.

"The range is {y| y >= 60}"

Correct. The range represents the total cost of a yearly membership. When you get the membership, you're ALWAYS going to have to pay $60, no matter how many tokens you buy after that.
