56 sets of pictures she can post on her wall

It is given that alyssa's favorite tennis team has 8 players on them. She has taken a picture with every single athlete individually and wants to post some of the pictures on her wall. But she only wants to post 3 pictures on her wall.

For this we hve to use factorials. In mathematics, the factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. The factorial of n also equals the product of n with the next smaller factorial: For example, The value of 0! is 1, according to the convention for an empty product.

So it will be - [tex]\frac{8!}{3!(8-3)!}[/tex] as this is the formula for combination

This will be 56.

In the give diagram, the value of f is 6.0

From the question, we are to determine the value of f

Using the law of sines, we can write that

[tex]\frac{f}{sinF} =\frac{e}{sinE}[/tex]

From the given information,

F = 27°

e = 13

E = 98°

Putting the parameters into the equation, we get

[tex]\frac{f}{sin(27)} =\frac{13}{sin(98)}[/tex]

[tex]\frac{f}{0.4540} =\frac{13}{0.9903}[/tex]

[tex]f=\frac{13 \times 0.4540}{0.9903}[/tex]

Answer:

(x+1)²+(y-2)²= 20

Step-by-step explanation:

P = (-3,-2)

Q = (1, 6)

Center (h, k)

C = ((-3+1)/2 , (-2+6)/2)

C = (-2/2 , 4/2)

C = (-1 , 2)

Radius = Distance from the center to point Q

R = √((1-(-1))² + (6-(2))²)

R = √((2)² + (4)²)

R = √(4+ 16)

R = √20

Equation

(x-h)²+(y-k)²= R²

(x-(-1))²+(y-2)²= (√20)²

(x+1)²+(y-2)²= 20

After completing their trade, Store Owner A has 0 puzzles and 10 puppets, and Store Owner B has 30 puzzles and 0 puppets.

Here,

Let's assume the two toy store owners are Store Owner A and Store Owner B.

Before the trade, Store Owner A has 30 puzzles and 0 puppets, and Store Owner B has 0 puzzles and 10 puppets.

They agree to trade 30 puzzles for 10 puppets at a rate of 3 puzzles for each puppet.

So, for every 3 puzzles, Store Owner A will receive 1 puppet.

Store Owner A gives away 30 puzzles and receives 30 / 3 = 10 puppets.

After the trade, Store Owner A has 0 puzzles and 10 puppets.

Store Owner B gives away 10 puppets and receives 10 * 3 = 30 puzzles.

After the trade, Store Owner B has 30 puzzles and 0 puppets.

So, after completing their trade, Store Owner A has 0 puzzles and 10 puppets, and Store Owner B has 30 puzzles and 0 puppets.

The sample space neeeded for the experiment to find the face cards is 52.

Given there is a standard deck of cards.

We have to finf the sample space needed for the experiment of finding the probability of face cards.

Probability is the chance  of happening an event among all the events that are possible. It lies between 0 and 1. The probability is the number of items divided by the total items.

Sample is a part of population. It is studied when the study of whole population is difficult to do.

Cards in a deck=52

Number of face cards is 12.

When we  draw a card from the deck then it might be a face card or not. So we have to draw all the cards of a standard deck because it might possible that face card is present at the end of deck.

The rational function that meets all the conditions is:

[tex]f(x) = \frac{-15}{(x - 3)*(x + 5)}[/tex]

A rational function is of the form:

[tex]f(x) = \frac{p(x)}{q(x)}[/tex]

As the horizontal asymptote is at y = 0, we know that the numerator can't depend on x, so it is just a constant.

p(x) = a

And we want to have two vertical asymptotes at x = 3 and x = -5, then q(x) becomes zero at these values, so we have:

q(x) = (x -3)*(x + 5)

At this point, the function is:

[tex]f(x) = \frac{a}{(x - 3)*(x + 5)}[/tex]

Finally, we know that the y-intercept is 1, then we need to solve:

[tex]f(0) = 1 = \frac{a}{(0 - 3)*(0 +5)} = \frac{a}{-15} \\\\-15 = a[/tex]

Then we conclude that our function is:

Answer:

the slope of a line is parallel to the line is (3,-2)

(0,2)

Answer:

(2,3),(4,3),(-2,-3),(-4,-3)

Step-by-step explanation:

A function is defined as a relation in which each domain element (x-value) is paired with exactly one range element (y-value).

This means that each value we input for x must have only one possible output. If the same x-value yields more than one y-value, it is not a function.

The correct answer, as shown above, meets the criteria of a function, as each x-value is shown to produce exactly one y-value. In this set of ordered pairs, if x = 2, then y = 3, and if x = -2, then x = -3.

A set of ordered pairs is not a function if there are ordered pairs with the same x-values but different y-values.

In the other sets of ordered pairs, one x-value has more than one possible y-value. Let's use the last set as an example:

(5,1),(5,2),(5,3),(5,4)

Inputting 5 as x produces four different y values; there is no one y value for the x-value. y could equal 1, 2, 3, or 4.

Answer:

Step-by-step explanation:

Answer:

21.1

Step-by-step explanation:

sin 49 = x / 28

0.75470958 = x/28

x = 21.1

Answer:

x=18.4

y=35

Step-by-step explanation:

So to solve for x, you're going to use one of the six trigonometric functions (you really only need to use the three main ones, sin, cos, and tan, to solve these problems). In this case you know the adjacent of the angle 49 degrees, and the hypotenuse. There is a trigonometric function which is defined as: [tex]\frac{adjacent}{hypotenuse}=cos(\theta)[/tex]. So let's plug in the known values:

[tex]cos(49) = \frac{x}{28}[/tex]

Multiply both sides by 28

[tex]cos(49) * 28 = x\\[/tex]

Calculate cos(49) using a calculator (make sure it's in degree mode):

[tex]0.656 * 28 \approx x[/tex]

[tex]18.4 \approx x[/tex]

So the second problem, you need to use the inverse of one of the trigonometric function, which essentially takes what f(x) is, and returns x. So in this case we're looking for a trigonometric function that is defined using the opposite and adjacent side, which tan is. [tex]tan(\theta)=\frac{opposite}{adajcent}[/tex]. In this case opposite=19, and adjacent=27. So plug in the known values:

[tex]tan(y)=\frac{19}{27}[/tex]

Apply the inverse of tan to both sides

[tex]y=tan^{-1}(\frac{19}{27})[/tex]

Calculate inverse of tan of 19/27 using a calculator:

[tex]y\approx35[/tex]

The solution to the equations 2x + 3y = 3, x – 2y = 5 using substitution method is y = -1 and x = 3 respectively.

2x + 3y = 3

x – 2y = 5

from equation (2)

x = 5 + 2y

Substitute x = 5 + 2y into equation (1)

2x + 3y = 3

2(5 + 2y) + 3y = 3

10 + 4y + 3y = 3

10 + 7y = 3

7y = 3 - 10

7y = -7

y = -7/7

y = -1

Substitute y = -1 into (2)

x – 2y = 5

x - 2(-1) = 5

x + 2 = 5
