The rule for the linear function is f(x) = (-1/2)x + 11/2

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

To write the rule for the linear function, we can start by finding the slope of the line passing through the given points (x, y):

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope= (6 - 2) / (-1 - 7)

Slope= 4 / (-8)

Slope= -1/2

Therefore, the slope of the line passing through these points is -1/2.

Now, we can use the point-slope form of a linear equation to find the equation that represents this relationship:

y - y₁= m(x - x₁)

Where m is the slope and (x1, y1) is any point on the line. Let's use the point (7, 2):

y - 2 = (-1/2)(x - 7)

y - 2 = (-1/2)x + 7/2

y = (-1/2)x + 11/2

Therefore, the rule for the linear function is f(x) = (-1/2)x + 11/2

To determine whether the sequence with the given nth term is monotonic and bounded, we can look at the first derivative of the function.

The nth term an = 8n/(n+6) can be rewritten as an = 8 - 48/(n+6).

Taking the first derivative, we get a'(n) = 48/(n+6)^2, which is always positive for n>0.

This means that the sequence is monotonic increasing.

To determine whether the sequence is bounded, we can take the limit as n approaches infinity.

lim n→∞ an = lim n→∞ 8n/(n+6) = 8

This means that the sequence is bounded above by 8, and since it is increasing, it is also bounded below by its first term a1 = 8/7.

Therefore, the sequence with the nth term an = 8n/(n+6) is monotonic and bounded.

To confirm our results, we can graph the function and see that it is indeed increasing and approaches 8 as n increases.

Describe a yard.

In both the British Imperial and US Customary Systems of Measurement, a yard is a unit of length. It corresponds to 3 feet or 36 inches. Yd is its emblem. Medium-sized object length is frequently measured using it.

How do you convert square yards to area feet?

To get the area value, multiply it by 9. To change the area from square feet to square yards, all you need to do is that. For instance, you must multiply 27 by 9 to convert 27 square feet to square yards.

Floor space is 15 x 12 ft², or 180 ft².

We know that 9ft² is 1 yard

So 180ft2 = 1/9*180 square yard

               = 20 square yard

Cost of 1 square yard = carpet cost + installation cost

                                  = $27.50 + $4.15

                                  = $31.65

Cost of 20 square yard = 20 * 31.65

A coin that comes up heads with probability p is continually flipped until the pattern t, t, h appears, the expected number of flips needed to obtain the pattern "t, t, h" is 6/p.

We can approach this problem by using the concept of geometric distribution, which models the number of independent and identical Bernoulli trials (coin flips) needed to obtain the first success (in this case, the pattern "t, t, h").

Let X be the random variable representing the number of flips needed to obtain the pattern "t, t, h". The probability of obtaining "t, t, h" on any given three flips is (1-p)(1-p)p, and the probability of not obtaining this pattern on any given three flips is 1 - (1-p)(1-p)p.

Thus, X follows a geometric distribution with parameter p, and its probability mass function is given by:

P(X=k) = (1-p)(1-p)p^(k-3), for k=3, 4, 5, ...

The expected value of a geometric distribution with parameter p is given by 1/p. Therefore, the expected number of flips needed to obtain the pattern "t, t, h" is:

E[X] = 1/p + 2/p + 3/p = (1+2+3)/p = 6/p.

We have shown that {Xn, n > 0) is a DTMC, assuming that the successive random drawings of the balls are independent by using the Memoryless property and Time-independent transition probabilities.

(1) Memoryless property:

Suppose we are at time n and know that Xn = i.

To determine the probability of moving to state j at time n+1, we only need to know the number of balls in urn A at time n and the number of balls that are drawn at time n+1.

The past history of the chain before time n is irrelevant. Therefore, the Markov chain has a memoryless property.

(2) Time-independent transition probabilities:

To calculate the transition probability from state i to state j, we need to consider the possible ways in which the number of balls in urn A can change from i to j. The transition probability from state i to state j is given by:

P(i,j) = P(Xn+1 = j | Xn = i) = P(Xn+1 = j | Xn = i, ball drawn from urn A) * P(ball drawn from urn A) + P(Xn+1 = j | Xn = i, ball drawn from urn B) * P(ball drawn from urn B)

= P(Xn+1 = j-1 | Xn = i, ball drawn from urn A) * (i/N) + P(Xn+1 = j+1 | Xn = i, ball drawn from urn B) * ((N-i)/N)

= (i-1)/(N-1) * (i/N) + (N-i-1)/(N-1) * ((N-i)/N)

= (i-1)(N-i)/N(N-1) + (N-i-1)i/N(N-1)

Therefore, the transition probability matrix is given by:

P = [P(i,j)] =

[(N-2)/N(N-1) 2/N(N-1) 0 0 ... 0]

[(N-3)/(N-1)(N-2) (N-1)/(N-1)(N-2) 2/N(N-2) 0 ... 0]

[0 (N-4)/(N-2)(N-3) (N-2)/(N-2)(N-3) 3/N(N-3) ... 0]

[0 0 (N-5)/(N-3)(N-4) (N-3)/(N-3)(N-4) ... 0]

[ ........................................... ]

[ 0 0 ... 0 2/N(N-1) (N-2)/N(N-1)]

Answer: The zeroes of a polynomial function are the values of x!

Step-by-step explanation:

The zeroes of a polynomial function are the values of x at which the polynomial is equal to zero. The zeroes of a polynomial can be found by setting the polynomial equal to zero and solving for x. For example, if the polynomial is f(x) = x^2 + 3x – 4, then the zeroes are -4 and 1. This is because when x = -4, f(-4) = 0 and when x = 1, f(1) = 0.

Step-by-step explanation:

zeroes of a function are the values of x that create the functional value 0.

since we have been given just 4 answer options, we could play "trial and error" to find the right one.

or we could think a little bit.

F(x) = x³ - x² - 6x = x(x² - x - 6) = x(x - 3)(x + 2)

and so the zeros are all values of x that cause that expression to be 0. and that means any value of x that sets one of the factors to 0.

x = 0 is clear.

x = 3 (3 - 3 = 0)

and

x = -2 (-2 + 2 = 0)

are the other 2 zeros.

that means D is the right answer.

The angles from smallest to largest are ∠A, ∠C, ∠B and the order of sides from smallest to largest is BC, AB, AC.

A triangle is a two dimensional figure which consist of three vertices, three edges and three angles.

Sum of the interior angles of a triangle is 180 degrees.

Given a triangle ABC.

The two angles of a triangle is given as 21° and 96°.

∠A = 21° and ∠B = 96°.

We have the fact that, the sum of the interior angles of a triangle is 180 degrees.

So, ∠A + ∠B + ∠C = 180°

21° + 96° + ∠C = 180°

∠C = 63°

The side opposite the smallest angle will be the smallest side.

So, the side opposite ∠A = 21° is BC, which is the smallest side.

The side opposite ∠C = 63° is AB , which is the second largest side.

The side opposite ∠B = 96° is AC, which is the largest side.

Hence the order of angles and side are ∠A, ∠C, ∠B and BC, AB, AC respectively.

To prove that F2(f) = f(-x), we can use the definition of the Fourier Transform.

Which is,

F{f(t)} = ∫ f(t) e^(-jwt) dt

Using this definition, we can find the Fourier Transform of F{f(t)}:

F{F{f(t)}} = ∫ F{f(t)} e^(-jwt) dt

= ∫ (∫ f(u) e^(-jvu) du) e^(-jwt) dt

= ∫ f(u) (∫ e^(-jvu) e^(-jwt) dt) du

The inner integral can be simplified as follows:

∫ e^(-jvu) e^(-jwt) dt = ∫ e^(-j(uv+w)t) dt

= δ(vw+u)

where δ is the Dirac delta function. This integral evaluates to 1 when v*w+u=0 and 0 otherwise. Thus, we can simplify the expression for F{F{f(t)}}:

F{F{f(t)}} = ∫ f(u) δ(v*w+u) du

= f(-v) (using the property of the Dirac delta function)

Note that we have substituted v for -w to make the result more readable.

Therefore, we have shown that F{F{f(t)}} = f(-v). Since F2(f) = F{F{f(t)}}, we can conclude that F2(f) = f(-x), as required.

If a minor league baseball park has 7000 seats. Box seats cost $6, grandstand seats cost $4, and bleacher seats cost $2.  x = 400, y = 5400, z = 1200.

The two equations are

x + y + z = 7000

6x + 4y +2z = 26400

Hence,

1/3z + y + z= 7000

4/3z+ y= 7000

y= 7000 - 4/3z

Substitution

6×1/3z + 4×(7000 - 4/3z) + 2z= 26400

Solving for z

2z + 4×7000 - 4×4/3z + 2 z= 26400

2z + 28000 - 16/3z + 2 z= 26400

2z - 16/3z + 2z= 26400 - 28000

-4/3z= -1600

z= (-1600)÷ (-4/3)

z= 1200

So,

x= 1/3z

x= 1/3×1200

x = 400

y= 7000 - 4/3z
