Find dy/dx when y = ( 2x+1)^3

Answer:

26 units

Step-by-step explanation:

AD = 9 -2 = 7 units long. BC is the same. so we have 2 X 7 = 14.

DC is 9 - 3 = 6 units long. AB is the same. so we have 2 X 6 = 12.

perimeter = 14 + 12 = 26 units

The slope (m) and y-intercept (b) with the equation of the line in slope-intercept form are given as: m = 2 and b = 5 is y = 2x + 5; m = 3 and b = 5 is y = 3x + 5; m = 5 and b = 4 is y = 5x + 4.

If m represents the slope of a line and b represents its y-intercept, the equation of the line in slope-intercept form is written as: y = mx + b.

Where m = 2 and b = 5, the equation of the line would be expressed as: y = 2x + 5.

Where m = 3 and b = 5, the equation of the line would be expressed as: y = 3x + 5.

Where m = 5 and b = 4, the equation of the line would be expressed as: y = 5x + 4.

The circumference of a circle with a radius of 21 centimeters is 132 centimeters.

The circumference is the distance around the boundary of a closed curve or shape. In the case of a circle, the circumference is the total length of the circular boundary.

To find the circumference of a circle with a radius of 21 centimeters, we can use the formula C = 2πR, where R is the radius and π is the mathematical constant approximately equal to 22/7.

Substituting the given values:

C = 2 x (22/7) x 21

C = (44/7) x 21

C = 924/7

C ≈ 132 centimeters

Therefore, the circumference of a circle with a radius of 21 centimeters is 132 centimeters.

Symmetry means,  hmmm usually a mirror image.

So when something is symmetry to another, is a way to say, one is the mirror image of the other, or namely they're just identical twins.

Now, if know that B is the midpoint, by definition is cutting AC into two equal halves, so AB is the mirror image of BC, so they're identical twins, there are no flaws, Q.E.D.

Check the picture below.

By rewriting the 3 given systems, we will see that:

1) Independent and inconsistent.

2) Independent and consistent.

3) Independent and inconsistent..

Let's analyze each system.

Let's look at the first one, we can rewrite it as:

y = 3x - 1

And, 2y - 6x = 4

2y = 6x + 4

y = 3x + 2

Here both lines have the same slope, so the lines never do intersect, meaning that the system is inconsistent and independent.

Now let's look at the second system, we can rewrite it as:

2y = - x + 6

And, 4y + 2x = 12

y = - 1/2x + 3

So, the slopes are different, meaning that we have one solution, so this system is consistent and independent.

For the final system we have:

y = 2x + 3

x + y = - 9

So, the slopes are different, meaning that we have one solution, so this system is consistent and independent.

The expression that represent the perimeter of the triangle is 3d² - 4d + 1.

The perimeter of any two-dimensional figure is simply the distance around the figure.

Hence, the perimeter of the triangle is the sum of all its 3 side lengths.

From the diagram:

Side length 1 = ( d² + 3 )

Side length 2 = ( 4d² + 3d - 2 )

Side length 3 = ( -2d² - 7d )

Hence, the perimeter of the triangle will be:

Perimeter = side length 1 + side length 2 + side length 3

Plug in the expressions

Perimeter = ( d² + 3 ) + ( 4d² + 3d - 2 ) + ( -2d² - 7d )

Collect and add like terms:

Perimeter = d² + 3 + 4d² + 3d - 2 + -2d² - 7d

Perimeter = d² + 4d² - 2d² + 3d - 7d + 3 - 2

Perimeter = 3d² - 4d + 1

The first time that Account X will have more money than Account W, excluding the initial deposits, is in the fifth month.

To determine when Account X will contain more money than Account W, we need to compare the balances of the two accounts each month until Account X surpasses Account W.

Let's analyze the balances of the two accounts month by month:

Month 1:

Account W: $0 + $100 = $100

Account X: $1 + 80% × $1 = $1 + $0.80 = $1.80

Month 2:

Account W: $100 + $100 = $200

Account X: $1.80 + 80% × $1.80 = $1.80 + $1.44 = $3.24

Month 3:

Account W: $200 + $100 = $300

Account X: $3.24 + 80% × $3.24 = $3.24 + $2.592 = $5.832

Month 4:

Account W: $300 + $100 = $400

Account X: $5.832 + 80% × $5.832 = $5.832 + $4.6656 = $10.4976

Month 5:

Account W: $400 + $100 = $500

Account X: $10.4976 + 80% × $10.4976 = $10.4976 + $8.39808 = $18.89568

Please note that the values provided in this calculation assume no withdrawals and no interest earned on the balances.

The range of the data is the difference of maximum and minimum values.

According to description of the box plot, the minimum value is 6 and maximum value is 18.

Hence the range is:

Answer:

x = 65 degrees

Step-by-step explanation:

The sum of all 4 interior (inside) angles in a quadrilateral = 360.

So 82+118+95+x = 360.

295+x = 360

x = 360-295

x = 65

Check that all the angles add up to 360:

82+118+95+65 = 360

The solution is:

[tex]\int\limits^a_b {\frac{x^{3} }{x^{2} + x -2 } } \, dx[/tex] =[tex]ln|x| + \frac{2}{5} ln|x+2| + \frac{1}{3} ln|x-1| + C[/tex]

The partial fraction expansion of a rational fraction is  described as an operation that consists of expressing the fraction as a sum of a polynomial and one or several fractions with a simpler denominator.

To solve the above partial fraction decomposition,

[tex]x^3 + x^2 - 2x = x(x^2 + x - 2) = x(x+2)(x-1)[/tex]

we then write the fraction as a sum of partial fractions:

[tex]fx-2dx = \frac{A }{x } + \frac{B}{x + 2 } + \frac{C }{x - 1}[/tex]

We  find the values of A, B, and C by  multiplying  both sides by the common denominator (x)(x+2)(x-1) and  substituting

fx-2dx = A(x+2)(x-1) + B(x)(x-1) + C(x)(x+2)

We set  x = 0

0 = -2A

A = 0.

We set  x = -2

-2 = 20B/(-2)(-4)

-2 = -5B

B = 2/5.

we set  x = 1

1 = 3C

C = 1/3.

fx-2dx = 0/x +  2/5/(x+2) +  1/3/(x-1)

We integrate each term separately and have the solution as :

[tex]\int\limits^a_b {\frac{x^{3} }{x^{2} + x -2 } } \, dx[/tex] =[tex]ln|x| + \frac{2}{5} ln|x+2| + \frac{1}{3} ln|x-1| + C[/tex].

The z-score for the raw score of 39 is 1.The z-score for the raw score of 30 is -0.8.Z-scores measure the number of standard deviations a raw score is from the mean. A positive z-score indicates a raw score above the mean, while a negative z-score indicates a raw score below the mean.

To find the z-scores, we need to use the formula:

z = (x - μ) / σ

where:

z is the z-score,x is the raw score,μ is the mean, andσ is the standard deviation.

Let's calculate the z-scores for the given mean of 34 and standard deviation of 5.For a raw score of 39:

z = (39 - 34) / 5

z = 5 / 5

z = 1

So, the z-score for the raw score of 39 is 1.For a raw score of 30:

z = (30 - 34) / 5

z = -4 / 5

Using the binomial distribution function:

P(X < 5) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)

P(X = k) = [tex](_nC_k) * p^{k} * (1 - p)^{(n - k)}[/tex]
