Answer 1

Answer:

x = 10.1

Step-by-step explanation:

The function SINE stands for Opp. / Hyp. the function that should be used is COSINE. We now know that cos(39) = x/13 and using a calculator we can substitute for cos(39).

Make sure your calculator is in degrees when plugging into your calculator so you don't use radians.

We get 0.777145961457 = x/13 now since we have substituted we can multiply both sides of the equation to get 10.1028974989 = x. When rounded, it is 10.1 units.

Answer:

the number if different possible poker hands is found by counting the number of ways that 5 cards can be selected from 52 cards.

Step-by-step explanation:

this is a valid answer for e2020

Final answer:

In poker, the number of microstates when dealing with five cards from separate decks is 52^5, and the probability of getting 5 queens of hearts is (1/52)^5. The probability of drawing any specific hand is also 1 in 380,204,032. Poker hand values are inversely proportional to their entropy, with rarer hands having greater value.

Explanation:

Calculations Involved in Poker Probabilities

The game of poker involves a combination of skill and luck, with probabilities playing a significant role in the strategy. To answer the student's questions regarding probabilities in poker, we need to delve into some detailed calculations.

Microstates in Poker: A microstate refers to a specific arrangement of cards. When dealing five random cards from five separate decks, we consider each deck to have 52 unique cards. The number of microstates would be 52^5 (or 380,204,032) because for each card drawn there are 52 possibilities, and each draw is independent from the others.Probability of getting 5 queens of hearts: Given that each deck has one queen of hearts, the probability of drawing the queen of hearts from each deck in one try is (1/52)^5, which is 1 in 380,204,032.Probability of a specific hand: Since there are 52 possible cards for each of the five draws, the probability of getting any specific hand of five cards, regardless of suit or rank, is also 1 in 380,204,032.

In analyzing poker hands and their respective values, we find that the value of a hand is typically inversely proportional to its entropy, meaning a less likely hand equates to a higher value.

Pascal's Wager as applied to gambling is not directly related to poker probabilities, but it is an interesting philosophical approach to decision-making under uncertainty. Rather than calculating monetary risk, it assesses the existential gamble of believing in a deity.

Understanding probabilities like these allows gamblers, politicians, teachers, doctors, and individuals in many other fields to make more informed decisions about probable outcomes.

A f(n)= 10n-13
B f(n)=-3n+10
C f(n)=10n-3
D f(n)=-3(n-1)+10

Answers

Answer:

The function is f(n) = 10n - 13 ⇒ answer A

Step-by-step explanation:

* Lets revise the arithmetic sequence

- There is a constant difference between each two consecutive

  numbers

- Ex:

# 2  ,  5  ,  8  ,  11  ,  ……………………….

# 5  ,  10  ,  15  ,  20  ,  …………………………

# 12  ,  10  ,  8  ,  6  ,  ……………………………

* General term (nth term) of an Arithmetic sequence:

# U1 = a  ,  U2  = a + d  ,  U3  = a + 2d  ,  U4 = a + 3d  ,  U5 = a + 4d

# Un = a + (n – 1)d, where a is the first term , d is the difference

  between each two consecutive terms, n is the position of the

  term in the sequence

* Now lets solve the problem

- The sequence is -3 , 7 , 17 , 27 , .........

∵ 7 - (-3) = 7 + 3 = 10

∵ 17 - 7 = 10

∵ 27 - 17 = 10

∴ The sequence is arithmetic with constant difference 10

∴ f(n) = a + (n - 1)d

∵ a = -3

∵ d = 10

∴ f(n) = -3 + (n - 1)(10) ⇒ lets simplify it

∴ f(n) = -3 + n(10) + (-1)(10) = -3 + 10n - 10 ⇒ add like terms

∴ f(n) = 10n - 13

* The function is f(n) = 10n - 13

Option A is the correct function to define the sequence. It starts at -3 when n=1 and increases by 10 as n increases, consistently matching the given sequence.

To determine which function could be used to define and continue the given sequence (-3, 7, 17, 27...), we need to analyze the pattern of differences between consecutive terms and see which option best represents this pattern. The sequence increases by 10 each time, as can be seen from the differences (7 - (-3) = 10, 17 - 7 = 10, 27 - 17 = 10).

Looking at the functions provided:

Option A: f(n) = 10n - 13If we put n=1, f(1) = 10*1 - 13 = -3; If we put n=2, f(2) = 10*2 - 13 = 7; and so on. The pattern matches.Option B: f(n) = -3n + 10 If we put n=1, f(1) = -3*1 + 10 = 7, which does not match the first term of our sequence.Option C: f(n) = 10n - 3 If we put n=1, f(1) = 10*1 - 3 = 7, which does not match the first term of our sequence.Option D: f(n) = -3(n - 1) + 10 If we put n=1, f(1) = -3*(1 - 1) + 10 = 10, which does not match the first term of our sequence.

Therefore, Option A is the correct function to define the sequence. It starts at -3 when n=1 and increases by 10 as n increases, consistently matching the given sequence.

Answer:

Option B: y = -2x + 17.

Step-by-step explanation:

Lets calculate values for option B:

x = 2 , y = -4+17 = 13   ( B gives the value 12)

x = 4, y = -8+17 = 9   (10)

x = 5, y = -10+17 = 7  (6)

The dimensions of the rectangle with an area of (81x² - 4y²) square units are (9x + 2y) and (9x - 2y) units, as the area expression is a difference of squares that has been factored accordingly.

The area of a rectangle is given by the expression (81x² − 4y²) square units. To determine the dimensions of the rectangle, we need to factor this expression completely.

This expression is a difference of squares and can be factored as follows:Use the difference of squares formula, which is a²- b² = (a - b)(a + b).Apply the formula: (81x² − 4y²) = (9x)² - (2y)² = (9x + 2y)(9x - 2y).

Therefore, the dimensions of the rectangle can be 9x + 2y and 9x - 2y units.

What are similar triangles?

Triangles with the same shape but different sizes are said to be similar triangles. Squares with any side length and all equilateral triangles are examples of related objects. In other words, if two triangles are similar, their corresponding sides are proportionately equal and their corresponding angles are congruent.

We have three similar triangles because each has a right angle and shares an angle.   Let's write the angles in order: opposite to the short leg, long leg, and the hypotenuse.

CAB ≡ BAD ≡ CBD

Or as ratios,

CA:AB:CB = BA:AD:BD = CB:BD:CD

We also know

AC = AD + CD

(AD+CD):AB:CB = BA:AD:BD = CB:BD:CD

(AD+CD)/CB=CB/CD

Let CD = x

(5 +x )/6 = 6/x

(5+x)*x = 6*6

5x + x² = 36

x² + 5x - 36 = 0

x² + 9x -4x -36 = 0

x(x+9 ) -4 (x +9 ) = 0

(x-4)(x+9) = 0

x= 4, -9

Line CD passes through (0, 1) and is parallel to x + y = 3. Write the standard form of the equation of line CD. x + y = 1 x – y = 1 x + 1 = y x + y = 11

Answers

ANSWER

x+y=1

EXPLANATION

We want to find the equation of line CD which passes through (0, 1) and is parallel to x + y = 3.

In slope intercept form, the given line is

y=-x+3

The slope of this line is m=-1

Line CD also has the same slope

The equation is given by:

y=mx+b

The given point (0,1) means the y-intercept;is b=1

Hence the equation is

y=-x+1

In standard form the equation is:

x+y=1

Answer:

The answer is x + y = 1

Step-by-step explanation:

Given: Line CD passes through (0, 1) and is parallel to x + y = 3.

We know that if two line are parallel then they have equal slopes.

Thus, the slope of line = slope of line x + y = 3

 x + y = 3  when we compare this to the standard linear equation

= 3 - x

y = m x + c  .we get m = -1 .

The slope of CD (m)= -1

Now, the equation of line CD passing through (0,1) is given by :-

( y - 1 ) = m ( x - 0 )

⇒ ( y - 1 ) = ( -1 ) x

⇒ x + y = 1

The equation of line CD = x + y = 1

What is the average rate of change from x = −3 to x = −4?

Answers

Answer:

-2

Step-by-step explanation:

Since it would be immensely helpful to know the equation of this parabola, we need to figure it out before we can continue.  We have the work form of a positive upwards-opening parabola as

[tex]y=a(x-h)^2+k[/tex]

where a is the leading coefficient that determines the steepness of lack thereof of the parabola, x and y are coordinates of a point on the graph, and h and k are the coordinates of the vertex.  We know the vertex: V(-3, -3), and it looks like the graph goes through the point P(-2, -1).  Now we will fill in the work form equation and solve for a:

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

which simplifies a bit to

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

and

-1 = a(1) - 3.  Therefore, a = 2 and our parabola is

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

Now that know the equation, we can find the value of y when x = -3 (which is already given in the vertex) and the value of y when x = -4.  Do this by subbing in the values of x one at a time to find y.  When x = -3, y = -3 so the coordinate of that point (aka the vertex) is (-3, -3).  When x = -4, y = -1 so the coordinate of that point is (-4, -1).  The average rate of change between those 2 points is also the slope of the line between those 2 points, so we will use the slope formula to find it:

[tex]m=\frac{-1-(-3)}{-4-(-3)} =\frac{2}{-1}=-2[/tex]

And there you have it!  I'm very surprised that this question sat unanswered for so very long!  I'm sorry I didn't see it earlier!

Final answer:

The practical domain of the function f(x), representing the height of a model rocket after launch, is [0,4], including the launch at time x=0, reaching the maximum height at x=2 seconds, and landing at x=4 seconds.

Explanation:

The practical domain for the function f(x), which represents the height of a model rocket x seconds after launch, refers to the interval of time during which the rocket is in flight. Since the rocket is launched at time x=0, reaches its maximum height at x=2 seconds, and hits the ground at x=4 seconds, the practical domain of f(x) is [0,4].

This domain includes all times from the launch to when the rocket lands, as the function's values will only be meaningful or defined within this interval.

f(x), and the maximum is 2.

g(x), and the maximum is 2.

Answers

Answer:

Second option

g(x), and the maximum is 5.’

Step-by-step explanation:

In the graph it can easily be seen that the maximum value reached by the function f(x) is y = 3.

Then, the function g (x) is:

[tex]g(x) = 3cos(\frac{1}{4}(x + \frac{1}{3}x)) + 2[/tex]

By definition the function

[tex]y = cos(x)[/tex] reaches its maximum value when x = 0,  [tex]2\pi[/tex],  [tex]4\pi[/tex], ..., [tex]2k\pi[/tex]

So

When [tex](\frac{1}{4}(x + \frac{1}{3}x)) = 0[/tex]  entonces [tex]cos((\frac{1}{4}(x + \frac{1}{3}x)) = 1[/tex].

Thus:

Two number cubes, each with the numbers 1 through 6, are rolled. What is the probability that the sum of the rolled numbers is 2? PLEASE HELP ANYONE IN LIKE @20 min

Answers

Final answer:

The probability of rolling a sum of 2 with two dice is 1/36. This is calculated by determining the independent probabilities of rolling 1 on each die and multiplying these probabilities together.

Explanation:

The subject of this question is probability in mathematics, specifically involving the numbers on two rolled dice. The only way two dice (number cubes) can add up to 2 is if both rolled dice shows 1. Each die has 6 sides, so the probability for each dies rolling 1 is 1/6.

The probability of two independent events both occurring is founding by multiplying the probability of each event. As the two dice is rolled independently, the probability of both are showing 1 (and hence their sum is being 2) is (1/6) x (1/6), which simplifies to 1/36. Therefore, the probability that the sum of the numbers rolled on two dice is 2 1/36.

Use the drop-down menus to complete each equation so the statement about its solution is true.
The drop down menus consist of numbers 0-9

Answers

Answer with explanation:

    A)

No solution--

No solution is obtained when there is a condition such that the equation gives a absurd condition.

Hence we write our equation as:

        2x+9+3x+x=6x+1

 Hence, we have:

          6x+9=6x+1

i.e. we have:   9=1

which is a contradiction.

Hence, we get no solution.

B)

         One solution--

One solution or unique solution is obtained when we obtain a unique value for our given variable.

i.e. if we write our equation as:

             2x+9+3x+x=5x+1

i.e. 6x+9=5x+1

i.e. x= -8

Hence, we get a unique value for x.

C)

            Infinite many solution--

The infinite many solution is where we get a condition such that we could not get a unique value for x but the equation is true.

Hence, we have:

                     2x+9+3x+x=6x+9

i.e.   6x+9=6x+9

as left hand side of equation is equal to right hand side of the equation for every ''x'' Hence, we get infinite many solution.

                 

Answer:

1. 6x+1

2. 5x+1

3. 6x+9

Antoine stands on a balcony and throws a ball to his dog, who is at ground level. The ball's height (in meters above the ground), xx seconds after Antoine threw it, is modeled by: h(x)=-2x^2+4x+16h(x)=−2x 2 +4x+16 What is the height of the ball at the time it is thrown?

Answers

Answer:

[tex]\boxed{\text{16 ft}}[/tex]

Step-by-step explanation:

h(x) = -2x² + 4x + 16

At the time the ball is thrown,

x = 0

h(0) = -2 × 0² + 4 × 0 + 16 = [tex]\boxed{ \textbf{16 ft}}[/tex]

Answer:

The height of the ball at the time it is thrown is 16 meters.

Step-by-step explanation:

To find the height of the ball at the time it is thrown, we have that we set the time accordingly. So the height of the ball at the time it is thrown is given by h(0) since the ball was thrown at second 0.

Now that we know the time, which is our x, we set all of our x's to 0.

[tex]h(0)=-2(0)^{2} +4(0)+16[/tex]

Next we solve,

      [tex]=0+0+16[/tex]

      [tex]=16[/tex]

In conclusion, the height of the ball at the time it is thrown is 16 meters.
