Suppose we want to choose 2 letter without replacement from the 3 letters a,b and c how many ways can this be done if the order of choice is taken into consideration and how many ways can this be done if the order of choices is not taken into consideration?

Answers

Answer 1

When not considering the order of choice, there are also 3 ways to choose 2 letters from a, b, and c.

How to determine in how many ways can this be done if the order of choices is not taken into consideration

When choosing 2 letters without replacement from the 3 letters a, b, and c, the number of ways can be calculated considering the order of choice and without considering the order of choice.

1. Considering the order of choice:

In this case, the order in which the letters are chosen matters. We can think of this as a permutation problem.

To calculate the number of ways when order matters, we use the formula for permutations:

[tex]nPr = n! / (n - r)![/tex]

where n is the total number of items and r is the number of items chosen.

In this case, we have 3 letters and we want to choose 2, so n = 3 and r = 2.

Using the formula, we get:

[tex]3P2 = 3! / (3 - 2)![/tex]

 [tex]= 3! / 1![/tex]

    = 3

Therefore, when considering the order of choice, there are 3 ways to choose 2 letters from a, b, and c.

2. Without considering the order of choice:

In this case, the order in which the letters are chosen does not matter. We can think of this as a combination problem.

To calculate the number of ways when order does not matter, we use the formula for combinations:

[tex]nCr = n! / (r!(n - r)!)[/tex]

Using the same values of n = 3 and r = 2, we get:

[tex]3C2 = 3! / (2!(3 - 2)!)[/tex]

    = [tex]3! / (2! * 1!)[/tex]

    = 3

Therefore, when not considering the order of choice, there are also 3 ways to choose 2 letters from a, b, and c.

The proof that the value of x is 38° is shown below

How to show that the value of x is 38°

From the question, we have the following parameters that can be used in our computation:

ABDE is a parallelogram.

The measure of the angle opposite the vertex x is

Angle = 180 - 68

Evaluate the like terms

So, we have

Angle = 112

Also, we have

B = 68

AB = AC

So, we have

y = 180 - 68 - 68

y = 44

Using the above as a guide, we have the following:

x + 44 = 82

So, we have

x = 82 - 44

The bedroom, garage, office, and bathroom of a house will be painted, each with a different color. There are 15 colors to choose from. This means that there are ________ color arrangements possible.

Answers

Answer: There are 32,760 color arrangements possible for painting the bedroom, garage, office, and bathroom with different colors chosen from 15 options.

Step-by-step explanation: To determine the number of color arrangements possible for painting the bedroom, garage, office, and bathroom with different colors chosen from 15 options, we need to calculate the number of permutations.

Since each room is assigned a different color, we can arrange the colors in a specific order. The number of ways to arrange 15 colors in 4 distinct positions is given by the permutation formula:

P(n, r) = n! / (n - r)!

where n is the total number of options (15 colors) and r is the number of positions (4 rooms).

Using the formula, the number of color arrangements possible is:

P(15, 4) = 15! / (15 - 4)!

= 15! / 11!

= (15 * 14 * 13 * 12) / (4 * 3 * 2 * 1)

= 32,760

5. The product of two complex numbers in rectangular form is  -36 - 2i

6. z1/z2 in polar form is z1/z2 = 4 cis (7π/6 - π/4)

How do we solve for the  complex (a + bi) form?

1. The location of each point A and B are as follows  Arrow A is at (4, 3) and arrow B (-6, 4). therefore the location in complex (a + bi) form is 4 + 3i, B is -6 + 4i.

2. The modulus of a complex number (a + bi) is represented as √(a² + b²) ⇒ √(4² + 3²) = √(16 + 9) = √25 = 5.

3. We can calculate the length of vector AB with √(x₂-x₁)² + (y₂-y₁)²)

AB = √((-6 - 4)² + (4 - 3)²)

AB = √((-10)² + 1)

AB = √(100 + 1)

AB = √101 ⇒ 10

4. The modulus of B, r = √((-6)² + 4²) = √(36 + 16) = √52 = 2√13

θ = 180° - arctan(|4/-6|) = 180° - arctan(2/3)

θ = 180° - 33.69° = 146.31°

5. The product of the complex number can be see as follows

(4 + 3i) × (-6 + 4i) = (4×-6 - 34) + (4×4 + 3×-6)i

= (-24 - 12) + (16 - 18)i

= -36 - 2i.

6. (7π/6 - π/4) = (14π/12 - 3π/12) = 11π/12.

Answers

The diameter of the reservoir is:

Part (a): 112.86 m

part (b): 56. 44 m

How to find the diameter of the reservoir?

The volume of a cylinder is given by the formula:

V = πr²h

where r is the radius and h is the height or depth

Part (a):

We have:

h = 10 cm = 0.1 m

V = 1000,000 litres = 1000 m³  (Remember: 1 litre = 1000 cubic metre)

V = πr²h

1000 = 3.14 * r² * 0.1

1000 = 0.314 r²

r² = 1000 / 0.314

r² = 3184.71

r = √3184.71

r = 56.43 m

Since diameter = 2 * r

diameter =  2 * 56.43

diameter = 112.86 m

part (b):

We have:

h = 10 cm = 0.1 m

V = 250,000 litres = 250 m³

V = πr²h

250 = 3.14 * r² * 0.1

250 = 0.314 r²

r² = 250 / 0.314

r² = 796.18

r = √796.18

r = 28.22 m

Since diameter = 2 * r

diameter =  2 * 28.22

diameter = 56. 44 m

A publisher for a promising new novel figures fixed costs​ (overhead, advances,​ promotion, copy​ editing, typesetting, and so​ on) at ​$51,000​, and variable costs​ (printing, paper,​ binding, shipping) at ​$1.50 for each book produced. If the book is sold to distributors for ​$12 ​each, how many must be produced and sold for the publisher to break​ even?

Answers

The publisher must produce and sell approximately 4,857 books to break even.

Let's denote the number of books produced and sold as "x."

The total fixed cost is given as $51,000.

The variable cost per book is $1.50, and since x books are produced and sold, the total variable cost would be 1.50x.

The selling price per book is $12, and since x books are sold, the total revenue would be 12x.

To break even, the total revenue must equal the total cost:

Total Revenue = Total Cost

12x = 51,000 + 1.50x

Subtracting 1.50x from both sides:

12x - 1.50x = 51,000

10.50x = 51,000

Dividing both sides by 10.50:

x = 51,000 / 10.50

x ≈ 4,857

Therefore, the publisher must produce and sell approximately 4,857 books to break even.

Samantha wants to enclose 1680 ft² for a rectangular horse pen. The length will be 2 ft longer than the width. Find the dimensions of the pen. (Hint: A = lw)

Answers

The dimensions of the rectangular horse pen are 40 feet (width) and 42 feet (length).

What are the dimensions of the rectangular horse pen?

The area of a rectangle is expressed as:

Area = length × width

Given that,  the length of the pen will be 2 feet longer than the width, so the width is x feet and the length can be expressed as (x + 2) feet.

Using area of rectangle:

Area = length × width

1680 = (x + 2) × x

Simplify

1680 = x² + 2x

x² + 2x - 1680 = 0

Solve for x:

Using factoring

(x + 42)(x - 40) = 0

Hence:

x + 42 = 0 or x - 40 = 0

x = -42 or x = 40

Since we are dealing with dimensions, we use the positive value:

The valid solution is x = 40.

This represents the width of the horse pen.

The length can be found by adding 2 to the width:

Length = x + 2

Plug in x = 40

= 40 + 2

= 42

Therefore, the length is 42 feets.

Find the quotient and remainder using synthetic division.

x^4-3x^3+9x+6/x+1

The quotient is

The remainder is

Answer:

Step-by-step explanation:

To use synthetic division, we need to set up the coefficients of the dividend polynomial in decreasing order of powers of x, including any missing terms with zero coefficients.

So we have:

Dividend: x^4 - 3x^3 + 9x + 6

Divisor: x + 1

We can represent the divisor as (x + 1) and set up the synthetic division table as follows:

-1 | 1 -3 9 0 6

| -1 4 -13 13

|___________________

| 1 -4 13 -13 19

The numbers on the first row of the table are the coefficients of the dividend polynomial in decreasing order of powers of x. The -1 on the left of the table is the opposite of the divisor, x + 1.

The first number in the second row is always 0, and we get it by bringing down the first coefficient, which is 1. To get the next number in the second row, we multiply the divisor, -1, by 1, and add the result to the second coefficient, which is -3. This gives us -1 x -3 = 3, which we write under -3 in the first row.

We repeat this process for the next numbers in the second row, always multiplying the divisor by the last number in the second row, and adding the result to the next coefficient in the first row. We continue until we reach the last coefficient in the first row.

The last number in the second row, 13, is the remainder of the division. The other numbers in the second row are the coefficients of the quotient polynomial in decreasing order of powers of x. So the quotient is:

x^3 - 4x^2 + 13x - 13

And the remainder is:

13

Therefore, the quotient is x^3 - 4x^2 + 13x - 13, and the remainder is 13.

To find a formula for the nth term of the sequence 250, 100, 40, we need to first determine the pattern or rule that generates the sequence. If we divide each term by the previous term, we get the following ratios:

100/250 = 0.4

40/100 = 0.4

We can see that each term is obtained by multiplying the previous term by the common ratio of 0.4.

Answers

After applying factorization of the given functions the evaluated expression comes out to be (2x + 1)(x² - x - 4.8), under the condition the given function is P(x)=2x × 3- 5.6x +1

In order to factorize the given polynomial P(x) = 2x³ - 5.6x + 1, we can apply the Rational Root Theorem. The theorem projects that in an incident when a  polynomial has integer coefficients, then any rational roots must have a numerator that divides the constant term and a denominator that divides the leading coefficient.
For the given case, the leading coefficient is 2 and the constant term is 1.
Hence, any rational roots must be of the form p/q where p divides 1 and q divides 2. This elaborates that the possible rational roots are ±1/2 and ±1.
We can observe these roots applying synthetic division. Using synthetic division with root -1/2 gives us:
-1/2 | 2   0   -5.6   1
    |    -1    0.8  -0.5
    -------------------
          2   -1   -4.8  0.5

To find the x-coordinate of the solution to the system of equations, we need to solve the system by eliminating either x or y. Let's eliminate y by multiplying the first equation by 3 and the second equation by 1:

Equation 1: 2x + y = -4 (multiply by 3)

Equation 2: 5x + 3y = -6 (multiply by 1)

Multiplying equation 1 by 3 gives us:

6x + 3y = -12

Multiplying equation 2 by 1 gives us:

5x + 3y = -6

Now we can subtract equation 2 from equation 1 to eliminate y:

(6x + 3y) - (5x + 3y) = -12 - (-6)

6x + 3y - 5x - 3y = -12 + 6

x = -6

Therefore, the x-coordinate of the solution to the system of equations is x = -6.

The correct option is: Ox=-6.[tex][/tex]

Assume that ryan does save 10% for retirement if he allocate the remainder of his take-home pay to entertainment then what percent of the total budget will entertainment compromise how much money will the budget towards entertainment in each month

Answers

Entertainment will comprise 90% of Ryan's total budget. He will allocate 90% of his monthly income towards entertainment expenses.

How to solve

According to the given information:

Let's assume Ryan's take-home pay is P dollars.

Assuming that Ryan puts aside 10% of his net income for his retirement plan, he will accumulate savings of 0.10P dollars.

After setting aside funds for retirement, the remaining portion of his net earnings will constitute 90% of the original amount, equating to 0.90P dollars.

Assuming that Ryan puts the remaining amount of his income towards entertainment, it is possible to determine the proportion of his overall expenses that entertainment would represent.

Percentage of entertainment budget = (Entertainment budget / Total budget) * 100

Given an overall budget of P dollars, with 0.90P dollars allotted for entertainment expenses, the proportion of the total budget that will be spent on entertainment can be calculated as a percentage.

Percentage of entertainment budget = (0.90P / P) * 100

Percentage of entertainment budget = 90%

So, entertainment will comprise 90% of Ryan's total budget.

He will allocate a monthly entertainment budget of 0.90P dollars, equivalent to 90% of his salary after taxes.

As such, the overwhelming majority of Ryan's budget will be allocated towards Entertainment. Every month, the entertainment allowance will constitute 90% of his net income as per the allocated budget.
