Answer 1

The number of arrangements when the order is considered is 12, Number of ways when the order is not considered is 6.

Permutaions and combinations:

By choosing some items from a set and creating subsets, permutation and combination are two approaches to express a collection of things.

The act of placing every member of a set into a certain sequence or order is known as permutation.

The combination is a method of choosing things from a group in which (unlike permutations) the order of the choices is irrelevant.  

The formula for Permutations is given by

                     ⁿP[tex]_{r}[/tex] = (n!)/(n-r)!

The formula for Combinations is given by

                    [tex]_{n}[/tex]C[tex]_{r}[/tex] = (n!)/r!(n - r)!  

Here we have

4 letters A, B, C, and D  

We need to choose 2 letters from the given 4 letters  

When the order of the choices is taking consideration we use the formula of Permutations  

The number of ways of arrangements,  ⁴P₂ = (4!)/(4-2)!  

= [tex]\frac{4\times 3\times\ 2!}{2!}[/tex]  = [tex]4 \times 3[/tex]  = 12

When the order of the choices is not taking consideration we use the formula of Combinations

Number of ways of arrangements, ₄C₂ = (4!)/2!(4 - 2)!  

= [tex]\frac{4\times 3 \times \ 2!}{2! \times 2!}[/tex] = [tex]\frac{4\times 3 }{2 \times 1 }[/tex]  = [tex]2\times 3[/tex]  = 6  

Therefore,

The number of arrangements when the order is considered is 12, Number of ways when the order is not considered is 6.

Suppose you can afford to pay $ 325 a month for 9 years towards a new car with no down payment. If the current interest rates are 4.75%, how expensive a car can you afford?
Car sticker price =

Answers

Using the interest rates formula, we know that an automobile that costs $24588.44 is within our means.

What are interest rates?

The amount of interest due each period expressed as a percentage of the amount lent, deposited, or borrowed is known as an interest rate.

The total interest on a loaned or borrowed sum is determined by the principal amount, the interest rate, the frequency of compounding, and the period of time the loan, deposit, or borrowing took place.

So, let's say the car's affordable price is P:

The entire payback is equal to P r/100 T + P.

In this case, P, r = 4.75, and T = 9 years.

$351,00 = P × (4.75/100 × 9 + 1)

$351,00 = P × ( 0.4275 + 1)

$351,00 = P × 1.4275

P = 351,00 / 1.4275

When you use the division operation, we receive:

P = $24588.44

Therefore, using the interest rates formula, we know that an automobile that costs $24588.44 is within our means.

Which of the following could be an example of a function with a range (-∞, α) and a domain [b, ∞) where a > 0 and b>0?

Answers

Answer:  Choice D

Explanation:

Choices A and B are ruled out because they are cube root functions, which have a domain and range of "all real numbers".

Choice C is ruled out because the domain is [tex][a, \infty)[/tex]

To determine this domain, we set the radicand (aka stuff under the square root) to be greater than or equal to zero.

[tex]x-a \ge 0 \ \ \text{ solves to } \ \ x \ge a[/tex]

[tex]x \ge a \ \ \text{ turns into the interval notation } \ \ [a, \infty)[/tex]

The square bracket is used to include the value 'a' as part of the interval. This is the interval from x = a to positive infinity.

The domain of choice D is [tex][b, \infty)[/tex] found using similar steps as shown above.

The range is [tex](-\infty, a][/tex] since this square root function is decreasing, due to the negative out front, which means y = a the largest output possible. I recommend graphing it out using a tool like desmos or geogebra. These tools offer a way to use parameters.

Samuel went to the grocery store and purchased cans of soup and frozen dinners. Each can of soup has 300 mg of sodium and each frozen dinner has 450 mg of sodium. Samuel purchased 5 more frozen dinners than cans of soup and they all collectively contain 6000 mg of sodium. Write a system of equations that could be used to determine the number of cans of soup purchased and the number of frozen dinners purchased. Define the variables that you use to write the system.

Answers

ax + by = 6000 and a + 5 = b are two equations that might be used to calculate how many soup cans and frozen dinners were purchased.

What is an equation?

There are several methods to define a formula. A mathematical statement that establishes the equivalence of two mathematical expressions is the definition of an equation in algebra.

This is best shown by the formula 3x + 5 = 14. In this instance, the word equal comes between the phrases 3x + 5 and 14. Even the most basic algebraic equations include the usage of mathematical variables.

Let frozen supper be y and soup cans be x.

X now has 300 mg of sodium in it.

x = 300

Y also has 450 mg of sodium in it.

y = 450

Samuel reportedly buys five more frozen dinners than soup cans, and they all have a combined salt content of 6000 mg.

Let the number of frozen dinners be "b," and the number of soup cans be "a."

ax + by = 6000

⇒ a(300) + b(450) = 6000 ...1

Samuel bought 5 more frozen dinners than soup cans, according to the inquiry, which results in equation

a + 5 = b ...2

Now, by changing the value of b in equation 1 we obtain,

⇒ a(300) + (a + 5)(450) = 6000

⇒ 300a + 450a = 6000 - 2250

⇒ 750a = 3750

⇒ a = 3750/750

⇒ a = 5

By changing the value of an in equation 2, we obtain

⇒ 5 + 5 = b

⇒ b = 10

So, ax + by = 6000 and a + 5 = b are two equations that might be used to calculate how many soup cans and frozen dinners were purchased, respectively, where x and y stand for soup cans and frozen dinners, respectively, and a and b stand for the quantity of soup cans and frozen dinners.

The diagram shows a frustum which is constructed from a pyramid.
(a) The surface area of the frustum.
(b) Find the volume of the frustum.
(c) Find the surface area of the original pyramid.

Answers

The surface area of the frustum is 1744 square units

The volume of the pyramid is 2031.33 cube units.

What is a frustum of a pyramid?

By cutting the top of a typical pyramid, the frustum is created, which is a pyramid. Because of this, it is known as a truncated pyramid. The frustum of the pyramid is that portion of a pyramid that is cut through by a plane parallel to its base and lies between the vertex and the base.

a) First, we calculate the height of the frustum.

Let height be H

The base length be L1=24

Base width be W1=12

Top length is L2=14

To width be W2=13

Side height be C=13

Using the formula, H

[tex]H=\sqrt{ C^{2} - \frac{(L1-L2)^{2}}{2}}\\H=\sqrt{ 13^{2} - \frac{(24-14)^{2}}{2}}\\H=\sqrt{ 169 -50}\\H=\sqrt{119} \\H=11[/tex]

Now, the surface area of the frustum is LSA+area of bases of a frustum

Here, P1= perimeter of the base1 of the frustum

P2 is the perimeter of the base 2 of the frustum

[tex]L.S.A=\frac{1}{2} .(P1+P2).L \\=\frac{1}{2} .(72+42).24 \\=\frac{1}{2} .(114).24 \\=1368[/tex]

Now, S1 =area of base1 of frustum =288

S2= area of base 2 of frustum=98

TSA is given by LSA+area of bases of a frustum

=1368+288+98

=1724.

Therefore the surface area is 1724 square units.

b) Volume is given by

[tex]V=\frac{1}{3}.H.(S1+S2+\sqrt{S1S2} )\\ V=\frac{1}{3} . 11.(386+168)\\V=2031.33[/tex]

Therefore the volume is 2031.33 cube units.

One of the fundamental mathematical operations is division, which involves breaking a bigger number into smaller groups with the same number of components. How many groups will be created, for instance, if 30 students need to be separated into groups of five for a sporting event? The division operation may be used to quickly and simply fix such issues. In this case, we must divide 30 by 5. 30 x 5 = 6 will be the outcome. There will thus be 6 groups with 5 students each. The initial number, 30, which is obtained by multiplying 6 by 5 may be used to confirm this figure.

The names of the phrases connected with the division process are referred to as division parts. The division is made up of the following four components: dividend, divisor, quotient, and remainder.

Two friends can divide 76 blueberries by dividing 76 divided by 10 .

The value we get is Divisor is 10 , Dividend is 76

So, The Quotient is 7 and Remainder is 6

So there will be 7 box of 10 blueberries and 1 box with 6 berries.

these final degrees.

Answers

Answer:

Bachelor's Degree: $55,000
Master's Degree: $61,000

Step-by-step explanation:

First start defining variables for each of the salaries

Let M be the salary of the master's individual

Let B be the salary of the bachelor's individual

Given:
Average yearly salary of an individual whose final degree is a master's is $49 thousand less than twice that of an individual whose final degree is a bachelor's

can be translated into the equation

M = 2B - 49,000

Subtract M from both sides and add 49,000 to both sides:

49,000 = 2B - M

Switch sides:

2B - M = 49,000   [1]

Together they earned 116,000 becomes

B + M = 116,000   [2]

Add equations [1] and [2] to eliminate M
2B - M + B + M = 49,000 +116000
3B = 165000

B = 165000/3 = 55,000

Using equation 2, B + M = 116000 we get

55000 + M = 116000

M = 116000 - 55000 = 61,000

Solution
Bachelor's Degree: $55,000
Master's Degree: $61,000

In circle radius OP intersects chord AC in point B.

And AB=8 units, BC=8 units

So, OP is perpendicular to AC.

Due to the fact that OA and OC have equal sides and a base length of AC, OAC forms a triangle (the radius of the circle)

FIND THE TWO POINTS HAVING AN X-COORDNATE OF 3 WHOSE DISTANCE FROM THE POINT(-2,-1) IS 13.
POINT 1: (3, ?)
POINT 2: (3, ?)

Answers

To find the two points having an x-coordinate of 3 whose distance from the point (-2, -1) is 13, you can use the distance formula:

Distance = √((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) is the coordinates of the first point, and (x2, y2) is the coordinates of the second point.

In this case, you can use the distance formula to find the y-coordinates of the two points having an x-coordinate of 3:

Distance = √((3 - (-2))^2 + (y - (-1))^2)

= √(5^2 + (y + 1)^2)

= √(25 + y^2 + 2y + 1)

= √(26 + y^2 + 2y)

= 13

If you set the distance equal to 13 and simplify the equation, you get:

y^2 + 2y + 12 = 0

This is a quadratic equation, which means it can be solved using the quadratic formula:

y = (-b ± √(b^2 - 4ac)) / (2a)

where a, b, and c are the coefficients of the quadratic equation.

Substituting the values into the quadratic formula, you get:

y = (-2 ± √(-2^2 - 4 * 1 * 12)) / (2 * 1)

= (-2 ± √(-4 - 48)) / 2

= (-2 ± √(-52)) / 2

Struggling on factoring quadratics. Could someone help me out with this worksheet, any examples of how to do the different types of problems would be great as well as finished problems

Answers

Answer:

When factoring, you want to get all of the terms on one side first and set all of it equal to 0. Many of the problems here are already in this format =0, but there are some where you'll have to move the terms around.

In these examples, it also looks like the highest power you have is x^2. This makes things easier to work with.

Let's just start with the first one, x^2 - 9x + 18 = 0.

We need to find two numbers that multiply to give us 18, and add together to give us -9. That would be -6 and -3.

-6 + -3 = -9

- 6 * -3 = 18

We can rewrite it now. This is the factored form.

(x - 6) * (x - 3) = 0

If you want to, you can go back to expanded form using the acronym 'FOIL'. First, Outside, Inside, Last. This refers to the order of multiplying the terms.

(x - 6) * (x - 3)

x * x = x^2

x * -3 = -3x

-6 * x = -6x

-6 * -3 = 18

Simplify

x^2 - 3x - 6x + 18 = 0

And we're back to where we started.

x^2 - 9x + 18 = 0

Hope this helps.

-2x-3y=-9 and-2x-3y=-9 by elimination

Answers

The system of equations has infinite solutions, actually, any pair (x, y) is a solution.

How to solve the system by elimination?

To solve a system by elimination, we just need to add/subtract the equations in such a way that we can remove one of the variables.

Here the system of equations is:

-2x-3y = -9

-2x-3y = -9

If we subtract the two equations we will get:

(-2x-3y) - (-2x-3y) = -9 - (-9)

0 = 0

This is a trivial equation, that happens because both equations of the system are the same one.

So the system is true for all real values of x and y.

Find the slope: (-1,1) and (-2,-3)
Thank you!

Answers

slope formula  can be illustrated  as ,  (y₂ - y₁) / (x₂ - x₁)

It is given in question that-

x₁ = -1 and y₁ = 1

x₂ = -2and y₂ = -3

so by using given formula for slope

slope= (y₂ - y₁) / (x₂ - x₁)

slope = (-3- (1) / (-2 - (-1) = (-3 - 1) / (-2 + 1) = -4/-1 = 4

final answer , slope =4

What is slope ?

The ratio of how much y grows as x grows by a certain amount is known as a line's slope. The slope of a line indicates how steep it is, or how much y rises as x rises. Anywhere along the line, the slope remains constant (the same).

Answer:

[tex] \sf \: slope(m) = 4[/tex]

Step-by-step explanation:

Now we have to,

→ find the required slope.

Formula we use,

→ Slope(m) = (y2 - y1)/(x2 - x1)

Then the slope will be,

→ m = (y2 - y1)/(x2 - x1)

→ m = (-3 - 1)/(-2 -(-1))

→ m = (-4)/(-2 + 1)

→ m = (-4)/(-1)

→ m = 4/1

→ [ m = 4 ]

Hence, the slope is 4.

Dos cuadrados de lado
10 cm se sobreponen formando un
rectángulo de 17 cm de largo, como se
muestra en la figura. ¿Cuál es el área
de la franja amarilla en centímetros
cuadrados?

Answers

La franja amarilla del rectángulo tiene un área de 30 centímetros cuadrados.

¿Cuál es el área de la franja amarilla del rectángulo?

En este problema tenemos un rectángulo formado por dos cuadrados que se traslapan uno al otro. La franja amarilla es el área en la que los cuadrados se traslapan. La anchura del rectángulo es descrita por la siguiente ecuación:

(10 - x) + 2 · x = 17

Donde x se mide en centímetros.

A continuación, despejamos x en la ecuación descrita:

10 + x = 17

x = 7

Ahora, el área de la franja amarilla se determina mediante la fórmula de area de un rectángulo:

A = b · h

Donde:

b - Base del rectángulo, en centímetros. h - Altura del rectángulo, en centímetros. A - Área del rectángulo, en centímetros cuadrados.

A = (10 - 7) · 10

A = 3 · 10

A = 30

El área de la franja amarilla del rectángulo es igual a 30 centímetros cuadrados.

In the figure below L || M. find X

Answers

Answer:

x = 79

Step-by-step explanation:

To find the value of x we first need to find the missing angle of the triangle in the image.

The sum of interior angles in a triangle is equal to 180°.

101 + 29 + missing angle = 180

Add like terms

130 + missing side = 180

subtract 130 from both sides

missing side = 50

Now, the sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angle.

So the value of x:

29 + 50 = 79
