In two or more complete sentences, prove how to find the third term of the expansion of

(x+2y)^4

Answers

Answer 1

Answer:

-2

Step-by-step explanation:

y = −2− x 2 y = - 2 - x 2

Answer 2

Answer:

[tex]24x^{2}y^2[/tex]

Step-by-step explanation:

[tex]\boxed{\begin{minipage}{5cm} \underline{Binomial Theorem}\\\\$\displaystyle (a+b)^n=\sum^{n}_{k=0}\binom{n}{k} a^{n-k}b^{k}$\\\\\\where \displaystyle \binom{n}{k} = \frac{n!}{k!(n-k)!}\\\end{minipage}}[/tex]

We can use the Binomial Theorem to find any term of a binomial expansion.  

The first term is when k = 0, so the third term is when k = 2.

Compare the given expression (x + 2y)⁴ with the formula to find the values of a, b and n.  

Therefore:

a = xb = 2yn = 4k = 2

Substitute the values into the formula to find the third term:

[tex]\implies \displaystyle\binom{4}{2}x^{4-2}(2y)^2[/tex]

[tex]\implies \dfrac{4!}{2!(4-2)!}x^{2}2^2y^2[/tex]

[tex]\implies \dfrac{4 \times 3\times \diagup\!\!\!\!2\times \diagup\!\!\!\!1}{2\times 1\times \diagup\!\!\!\!2\times \diagup\!\!\!\!1}\;x^{2}4y^2[/tex]

[tex]\implies \dfrac{12}{2}\:x^24y^2[/tex]

[tex]\implies 6x^{2}4y^2[/tex]

What is scientific notation?If a number is too big or too small to be conveniently represented in decimal form, it can be expressed using scientific notation. It might also be known as standard form in the UK, scientific form, or standard index form. A simple approach to write numbers is in scientific notation. Since it is shorter, more efficient, and clearly indicates magnitude, it is particularly helpful when expressing extremely big or extremely small values. Every real number can be expressed as the product of two elements, a decimal portion and an integer power of ten. The default base value ought to be 10. The exponent must be an integer that is not zero; therefore, it may be either positive or negative.

Find the general solution to
1/ln(t)(5e^t c) Enter your answer as y=…y=… .
Use C to denote the arbitrary constant in your answer.

Answers

y = c * 5e^t / ln(t) is the general solution to 1/ln(t)(5e^t c) .We can simplify this expression by applying the chain rule of differentiation. The chain rule states that if y = f(u) and u = g(x), then

dy/dx = dy/du * du/dx.  

The given expression is 1/ln(t)(5e^t c) .

In this case, we can let y = 5e^t c and u = ln(t).

Taking the derivative with respect to t, we get:

dy/dt = 5e^t c * (du/dt) / u

Since u = ln(t), we can use the chain rule again to find du/dt:

du/dt = 1/t

Plugging this back into the original expression, we get:

dy/dt = 5e^t c * (1/t) / ln(t)

Now we can factor out the constant c, which is an arbitrary constant of integration, giving us the final answer:

y = c * 5e^t / ln(t)

So the final answer is: y = c * 5e^t / ln(t)

It's important to note that this is only the general solution of the function, if we have an initial condition then we can find the specific solution for the function

Answers

The block's density can be calculated using the equation d=25g/8.4 cm.

What are equations?

Two things are equal, according to an equation.

For instance, 10 + 2 equals 6 + 6.

Simply put, this means that 10 plus 2 equals or is the same as 6 plus 6.

In an equation, the unknown could be present, as in 10 + x = 6 + 6.

So, find the block's volume first:

= Length * Width * Height

= 2 x 3 x 1.4

= 8.4 cm

Now that you know the volume and the mass, you can add them to the density formula, which is as follows:

= Mass / Volume

Assuming density is represented by the symbol b, the formula would be:

d = 25 g / 8.4 cm

Therefore, the block's density can be calculated using the equation d=25g/8.4 cm.

The train goes 10 mph faster than the boat . Abdul takes the train into the park and the boat on his way back. The boat goes an average speed of 20 mph. How long did the round trip​ take?

Answers

Answer:

1 hour 50 minutes

Step-by-step explanation:

Total distance from parking lot to entrance = 22 miles

We will assume that the total distance from entrance to lot is also 22 miles

The average speed of the boat = 20mph

The average speed of the train is 10 mph faster = 20 + 10 = 30 mph

Time taken for travel from parking lot to park by train  = 22/30 hours

22/30 hours = 22/30 x 60 minutes = 44 minutes

On the way back, the boat was taken
Distance = 22 miles, speed = 20 mph

Time taken = distance/speed = 22/20 hours

22/20 hours = 22/20 x 60 minutes = 66 minutes

Total round trip time taken = 44 + 66 = 110 minutes

110 minutes = 110/60 hours

Use drawings, numbers or words. Explain how you can use estimation to make sure your answer makes sense.

I need help on how to use estimation. Thanks!!

Answers

Answer:

Please see answer below

Step-by-step explanation:

An estimate is an answer to a problem that is close to the solution, but not necessarily exact. Estimation usually requires rounding

Usually you perform the estimate prior to computing actual values.

Let's look at the numbers

591 can be rounded to 600, 211 can be rounded to 200

Then, in your equations instead of using actual numbers we use the estimates

600 - 200 = 400

500 - 400 = 100

Note this is off quite a bit because we are rounding to the nearest 100

Instead if we round to the nearest tens we get

591 ==> 590
211 ==> 210

520==> 520

So we get

590 - 210 = 380

520 - 380 = 140

What is BD?

In triangle ABC, the length of side AB is 12 and the length of side AD is 27. The line AC started from point A and cuts the side BD a point C. The length of BC is x and the length of CD is x + 5.

Answers

The procedures below can be used to determine a triangle's length BD.

In th that is presented;

The holding ratio is, therefore, as follows:

12 : x = 27 : x + 5

12 / x = 27 / (x + 5 )

When we cross multiply these, we obtain:

12 ( x + 5 ) = 27x

12x + 60 = 27x

Taking the x values on one side, we obtain:

27x - 12x = 60

15x = 60

x = 60/15

x= 4

The length of line BD is:

= BC + CD

= x + x + 5

GRADES On his first five quizzes, Percy has earned scores of 24, 27, 22, 21, and 18 points. What score must Rachael earn on her sixth and final quiz so that both the mean and median of her quiz scores is 23?

Answers

Answer:

26

Step-by-step explanation:

To find the mean score of all six quizzes, you add all the scores and divide by the number of examinations. So if Percy's first five quiz scores are 24, 27, 22, 21, and 18, the total is 112. To find the mean score of all six quizzes, add Rachael's sixth quiz score to the total and divide by 6.

If the mean score of all six quizzes is 23, then the total score of all six examinations is 138 (23 x 6).

To find the score Rachael needs on her sixth quiz, you subtract Percy's score (112) from the total score of all six examinations (138)

Rachael needs to score 26 on her sixth quiz (138 - 112) for the mean and median of her quiz scores to be 23

c. Let f(x) = 2x. If we choose x = 3 and h = 2, then f(x + h) = f(3 + 2) = f(5) = 2(5) = 10, and f(x) + f(h) = f(3) + f(2) = 2(3) + 2(2) = 6 + 4 = 10. Therefore, the equation f(x + h) = f(x) + f(h) is true in this case.

26. The drama club is selling tickets for the upcoming play. Each student ticket costs $5.50 and each adult
ticket costs $9.50. If the Drama Club sold 98 tickets and raised $703, write a system of equations to figure out
how many of each ticket was sold. Find how many of each ticket was sold.

Answers

A total of 57 student tickets and a total of 41 adult tickets were sold to generate a total revenue of $703.

What is the definition of an equation?

A mathematical statement known as an equation is composed of two expressions joined together with the equal sign. A formula would've been 3x - 5 = 16, for illustration.. When this equation is solved, we discover that the quantity of the variables x is 7.

The following response has been produced in a straightforward, step-by-step manner.

Step: 1

Price of each student ticket = $ 5.50

Price of each adult ticket = $ 9.50

If x Equals the quantity of student tickets sold

If y Equals the quantity of adult tickets sold,

Step: 2

(i). It is given that a total of 98 tickets were sold.

Therefore, we can write as -

(Number of student tickets sold) + (Number of adult tickets sold) = 98

x+y =98 -----------equation (1)

Step: 3

(ii). The total revenue earned from the sale of tickets was $703.

Therefore, we can write as -

(Revenue earned from selling student tickets) + (Revenue earned from selling adult tickets) = 703

(Price of each student ticket×Number of student tickets sold) + (Price of each adult ticket ×Number of adult tickets sold) = 703

(5.50 × x)+ (9.50 × y) =703

5.50x+9.50y =703 ----------equation 2

Step: 4

System of Equations :

1) x+y =98

2) 5.50x + 9.50y =703

On performing (eq 2) - 5.50(eq 1), we get -

(5.50x +9.50y) - 5.50(x+y)=703-5.50(98)

5.50x + 9.50y - 5.50x-5.50y=703-539

4y=164

y=164/4

y=41

The operation was performed to reduce the equation in a single variable.

Step: 5

On substituting the value of y=41 in eq 1 , we get-

x+41 =98

x= 98-41

x=57

Thus, a total of 57 student tickets and a total of 41 adult tickets were sold to generate a total revenue of $703.

What is the function?

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

We have the following function:

(x)  = 3x - 7

The function f translated 6 units up and 2 units rights:

6 units up:

y  = 3x - 7 + 6

2 units rigth:

y  = 3(x-2) - 7 + 6

y  = 3x - 6 - 7 + 6

Finally:

g(x)  = 3x - 7

The function f reflected about the y-axis and translated 7 units left:

reflected about the y-axis:

y = 3(-x) - 7

y = -3x - 7

translated 7 units left:

y = -3(x+7) - 7

y = -3x - 21 - 7

y = -3x -28

Finally:

g(x) = -3x - 28

The function f stretched vertically by a factor of 2 and translated up by 5 units:

stretched vertically by a factor:

y = 6x - 14

translated up by 5 units:

y = 6x - 14 + 5

y = 6x - 9

Finally:

g(x) = 6x - 9

The function f stretched vertically by a factor of 4 and translated up by 9 units:

stretched vertically by a factor of 4:

y = 12x - 28

translated up by 9 units:

y = 12x - 28 + 9

y = 12x - 19

Finally:

g(x) = 12x - 19

Thus, the final equations are.:

g(x)  = 3x - 7g(x) = -3x - 28g(x) = 6x - 9g(x) = 12x - 19

I would like to build a program that calculates a student's score for a college admissions test. The program will be based on the coding requirements outlined by the college board, which include a list, an algorithm that uses sequencing, selection and iteration and a procedure that uses parameters.

The list will contain the student’s scores for each section of the admissions test. The algorithm will use sequencing to add the scores of each section together. Selection will then be used to determine whether the student has met the minimum requirements, and iteration will be used to keep track of any sections that were not completed. The procedure will be used to calculate the student’s total score, using parameters such as the number of sections completed and the scores for each section. The total score will be used to determine the student’s final admissions status.

The value of m∠1 is 50°. The solution is obtained using properties of angle and triangle.

What is an angle?

When two rays are brought together at a single point, an angle is created. The two rays in this instance are referred to as the arms of the angle, while the common point is known as the node or vertex. The symbol "∠" stands for an angle. Angle is a derivative of the Latin word "Angulus."

In the figure, we are given a right-angled triangle which means that one angle in the triangle measures 90°.

We are given an exterior angle equal to 140°.

We know that angles on a straight line form a linear pair which means that their sum is 180°.

Let the angle on the straight line be 'x'.

So, we get

⇒x + 140° = 180°

⇒x = 40°

Now, we know that in a triangle, the sum of all the angles is 180°.

Therefore,

⇒m∠1 + 90° + 40° = 180°

⇒m∠1 + 130° = 180°

m∠1 = 50°

Hence, the value of m∠1 is 50°.

create the following tables and calculate the average: mean use the additional column to caculate the frequency subtotal

Answers

To create the tables and calculate the average mean, we need to have a set of data that we want to organize in a tabular form. The table should have columns for the data values, frequency, and frequency subtotal. The frequency column will show how many times a particular data value appears in the set.

The frequency subtotal column will be used to find the sum of the product of each data value and its corresponding frequency.

The average mean can be calculated by dividing the sum of the frequency subtotal by the total frequency.

Mean = ([tex]f_{1}x_{1}[/tex] + [tex]f_{2}x_{2}[/tex]+ [tex]f_{3}x_{3}[/tex]+ ... + [tex]f_{n}x_{n}[/tex]) / ([tex]f_{1}[/tex]+[tex]f_{2}[/tex]+[tex]f_{3}[/tex]+...+[tex]f_{n}[/tex])

By creating this table, we can easily see the distribution of the data and can calculate the average mean. This method of organizing data in tabular form is commonly used in statistics and data analysis, and it is an efficient way of summarizing and understanding large sets of data.
