The solution of the function is 3, 3, 7, 15, 15 and 31.

Let's look at the recurrence relation you mentioned: T(n) = { 3 : n< 2 , 2T(n-2) + 1 : n≥ 2. This formula defines the function T(n) recursively, in terms of its previous values. To solve it using the unrolling method, we need to start with the base case T(0) and T(1), which are given by the initial condition T(n) = 3 when n < 2.

T(0) = 3

T(1) = 3

Next, we can use the recurrence relation to calculate T(2) in terms of T(0) and T(1):

T(2) = 2T(0) + 1 = 2*3 + 1 = 7

We can continue this process to compute T(3), T(4), and so on, by using the recurrence relation to "unroll" the formula and express each term in terms of the previous ones:

T(3) = 2T(1) + 1 = 23 + 1 = 7

T(4) = 2T(2) + 1 = 27 + 1 = 15

T(5) = 2T(3) + 1 = 27 + 1 = 15

T(6) = 2T(4) + 1 = 215 + 1 = 31

The given relation is R={(0,1),(1,0),(0,2)} on A={0,1,2,3}.

Reflexive closure of R:

To make R reflexive, we need to add (0,0), (1,1), (2,2), and (3,3) to it. Therefore, the reflexive closure of R is Rref={(0,1),(1,0),(0,2),(0,0),(1,1),(2,2),(3,3)}.

Symmetric closure of R:

To make R symmetric, we need to add (1,0), (2,0), and (2,1) to it. Therefore, the symmetric closure of R is Rsym={(0,1),(1,0),(0,2),(2,0),(2,1)}.

Transitive closure of R:

The given relation R is not transitive because (0,1) and (1,0) are in R, but (0,0) is not in R. To make R transitive, we need to add (0,0) to it. Then, we also need to add (1,2) and (0,2) to make it transitive. Therefore, the transitive closure of R is Rtrans={(0,1),(1,0),(0,2),(1,2),(2,0),(2,1),(0,0)}.

Reflexive transitive closure of R:

The reflexive transitive closure of R is simply the reflexive closure of the transitive closure of R. Therefore, the reflexive transitive closure of R is Rref-trans={(0,1),(1,0),(0,2),(1,2),(2,0),(2,1),(0,0),(1,1),(2,2),(3,3)}.

In order to find the measure of angle CEF, we need to use the property of angles formed by a transversal cutting two parallel lines.

Therefore, we will use the alternate interior angles property to find the measure of angle CEF.

Angles CDE and CEF are alternate interior angles formed by transversal CE that cuts the parallel lines AB and FD. This means that angle CDE and angle CEF are congruent angles.

Hence, we can say that:angle CDE = angle CEF = x degrees (let's say)Angle CEF and angle EFB are linear pairs, which means that they are adjacent angles and add up to 180 degrees.

This implies that:angle CEF + angle EFB = 180°Substituting angle CEF in the above equation, we get:x + 74° = 180°Solving for x: x = 180° - 74° = 106°Therefore, angle CEF is 106°.

Angle CDE is also 106° as we saw above. Angles CDE and CDB are adjacent angles and add up to 180 degrees.

Therefore:angle CDE + angle CDB = 180°Substituting the values of angle CDE and angle CDB in the above equation, we get:106° + angle CDB = 180°Solving for angle CDB:angle CDB = 180° - 106° = 74°Therefore, angle CDB is 74°. Hence, the measures of the angles CEF, CDE, and CDB are 106°, 106°, and 74°, respectively.

There are 5,040 different seating arrangements possible.

(a) To find the number of different juries possible, we can use the combination formula. We want to choose 6 men out of 14 and 6 women out of 13, so we have:

C(14, 6) x C(13, 6) = 1,352,697,600

Therefore, there are 1,352,697,600 different juries possible.

(b) To find the number of different seating arrangements possible, we can use the permutation formula. We know that we need to seat the jurors so that no two people of the same sex are seated next to each other. Let's start with the men - we have 6 men to seat, and they cannot be seated next to each other. We can think of this as creating "gaps" for the men to sit in. For example, if we have 6 men, we would need 7 gaps: _ M _ M _ M _ M _ M _ (where the underscores represent the gaps). Then we can choose which gaps the men will sit in, which we can do using the combination formula. We have 7 gaps to choose from, and we need to choose 6 of them for the men to sit in. Therefore, we have:

C(7, 6) = 7

Now we can seat the women in the gaps between the men. We have 6 women to seat, and we have 7 gaps for them to sit in (including the gaps at the ends). We can think of this as arranging the women and gaps in a line:

_ M _ M _ M _ M _ M _

We need to choose which 6 of the 7 gaps the women will sit in, and then arrange the women in those gaps. We can choose the gaps using the combination formula, and then arrange the women in those gaps using the permutation formula. Therefore, we have:

C(7, 6) x P(6, 6) = 7 x 720 = 5,040

Therefore, there are 5,040 different seating arrangements possible.

a. To find the joint pdf of Y1 and Y2, we can start by finding the transformation from (X1, X2) to (Y1, Y2):

Joint probability density function (joint PDF) is a concept used in probability theory and statistics to describe the probability distribution of multiple random variables simultaneously. It defines the likelihood of observing specific combinations of values for the variables.

Y1 = (X1/r1)/(X2/r2)

Y2 = X2

Solving for X1 and X2, we get:

X1 = r1Y1Y2

X2 = Y2

The Jacobian of this transformation is:

|J| = r1Y2

Using the transformation formula for joint pdfs, we have:

fY1,Y2(y1,y2) = [tex]fX1,X2(x1,x2) / |J|[/tex]

                    = [tex]fX1(r1y1y2, y2) * fX2(y2) / r1y2[/tex]

            =  [tex](1/2^(r1/2) * Gamma(r1/2)^(-1) * (r1y1y2)^(r1/2 - 1) * e^(-r1y1y2/2)) *(1/2^(r2/2) * Gamma(r2/2)^(-1) * y2^(r2/2 - 1) * e^(-y2/2)) / (r1y2)[/tex]

Simplifying this expression, we get:

[tex]fY1,Y2(y1,y2) = (r1r2/2^(r1/2 + r2/2) * Gamma(r1/2)^(-1) * Gamma(r2/2)^(-1) * y1^(r1/2 - 1) * y2^(r2/2 - 1) * e^(-(r1y1+y2)/2)) / y2[/tex]

b.  Y1 has an F distribution.

The marginal probability density function (marginal PDF) is a probability density function that describes the distribution of a single random variable from a joint probability distribution. It is obtained by integrating the joint PDF over all possible values of the other variables, effectively "marginalizing" or summing out the unwanted variables.

To find the marginal pdf of Y1, we integrate the joint pdf over Y2:

fY1(y1) = ∫fY1,Y2(y1,y2) dy2

       =[tex](r1r2/2^(r1/2 + r2/2) * Gamma(r1/2)^(-1) * Gamma(r2/2)^(-1) * y1^(r1/2 - 1) * e^(-r1y1/2) * ∫y2^(r2/2 - 1) * e^(-y2/2) / y2 dy2)[/tex]

       =[tex](r1/(r1 + 2y1))^(r1/2) / (B(r1/2, r2/2) * 2^(r1/2))[/tex]

where B is the beta function.

Recognizing the expression inside the integral as the pdf of a chi-square distribution with r2 degrees of freedom, we can evaluate the integral and simplify the result to get:

[tex]fY1(y1) = (r1/r2)^(r1/2) * y1^(r1/2 - 1) * (1 + r1/r2 * y1)^(-(r1+r2)/2) / (B(r1/2, r2/2) * 2^(r1/2))[/tex]

This is the pdf of an F distribution with r1 and r2 degrees of freedom, where F = Y1/(r1/r2).

Therefore, we have shown that Y1 has an F distribution.

The set of points at which the function is continuous h(x, y) = (eˣ eʸ)/ (eˣʸ - 1) when xy is not zero,or x or y is not zero.

To determine the set of points at which the function h(x, y) = (eˣ eʸ)/ (eˣʸ - 1) is continuous,

we need to look at the denominator of the expression, eˣʸ - 1. This denominator is equal to zero only when eˣʸ = 1, which means that xy = 0.

Therefore, the set of points where the function h(x, y) is not continuous is when xy = 0, or when x = 0 or y = 0.

At these points, the denominator of the expression becomes zero, and the function is not defined.

Thus, the set of points where the function h(x, y) is continuous is when xy ≠ 0, or when x ≠ 0 and y ≠ 0.

At these points, the denominator of the expression is never zero, and the function is well-defined and continuous.

The series converges on the interval from 7 inclusive to 9 exclusive.

To find the radius of convergence, we use the ratio test:

So the series converges absolutely if |x - 8| < 1, and diverges if |x - 8| > 1. Therefore, the radius of convergence is R = 1.

To find the interval of convergence, we need to test the endpoints x = 7 and x = 9:

When x = 7, the series becomes:

[infinity] (-1)ⁿ (n+9) / (n+1)

n = 0

which is an alternating series that satisfies the conditions of the alternating series test. Therefore, it converges.

When x = 9, the series becomes:

[infinity] 1 / (n+1)

n = 0

The determinant of the Hessian matrix is positive (80), and the second partial derivative with respect to x is positive, so the critical point is a minimum. Therefore, the minimum value of q is 285.

To minimize q=5x^2+4y^2 subject to the constraint x+y=9, we can use the method of Lagrange multipliers.

Let L = 5x^2 + 4y^2 - λ(x+y-9), where λ is the Lagrange multiplier.

Taking the partial derivatives of L with respect to x, y, and λ and setting them equal to zero, we get:

∂L/∂x = 10x - λ = 0

∂L/∂y = 8y - λ = 0

∂L/∂λ = x + y - 9 = 0

Solving these equations simultaneously, we get:

x = 18/7, y = 63/7, λ = 180/49

We can verify that this critical point is a minimum by checking the second partial derivatives of L. The second partial derivatives are:

∂^2L/∂x^2 = 10, ∂^2L/∂y^2 = 8, ∂^2L/∂x∂y = 0

The determinant of the Hessian matrix is positive (80), and the second partial derivative with respect to x is positive, so the critical point is a minimum.

Therefore, the minimum value of q is:

q = 5(18/7)^2 + 4(63/7)^2 = 1995/7 ≈ 285.

x^2 + 7x + (49/4) + y^2 - 2y + 1 + z^2 + 14z + 49 = -20 + (49/4) + 1 + 49

The equation of the elastic curve for portion ab of the beam is y = w/24 * e^(-x/4 * l) * (4l^2 - x^2)

The elastic curve equation for a simply supported beam with a uniformly distributed load is y = (w/(24 * EI)) * (x^2) * (3l - x), where w is the load per unit length, E is the modulus of elasticity, I is the moment of inertia, x is the distance from the left end of the beam, and l is the length of the beam.

In this case, we are given a load w, and a beam of length l. The elastic curve equation is given as y = w/24 * e^(-x/4 * l) * (4l^2 - x^2), which is a variation of the standard equation. The e^(-x/4 * l) term represents the deflection due to the load, while the (4l^2 - x^2) term represents the curvature of the beam.

To derive this equation, we first find the deflection due to the load by integrating the load equation over the length of the beam. This gives us the expression for deflection as a function of x.

We then use the moment-curvature relationship to find the curvature of the beam as a function of x. Finally, we combine these two expressions to get the elastic curve equation for the beam.

The answer is : OA. The statement is false because the focal diameter determines the size of the opening of the parabola. The larger the focal diameter, the wider the parabola.

The statement is false because the size of the opening of a parabola is determined by the distance between its focus and directrix, not by the focal diameter. The focal diameter is defined as the distance between the two points on the parabola that intersect with the axis of symmetry and lie on opposite sides of the vertex. It is twice the distance between the focus and vertex.

In a standard parabolic equation of the form y = ax^2 + bx + c, the coefficient a determines the "width" of the parabola. If a is positive, the parabola opens upwards, and if a is negative, the parabola opens downwards. The larger the absolute value of a, the narrower the parabola.

Therefore, a parabola with a larger focal diameter actually has a wider opening, since it corresponds to a smaller absolute value of a in the standard equation. Hence, the statement "A parabola with focal diameter 3 is narrower than a parabola with focal diameter 2" is false.

In other words, we need to satisfy the following condition:
∫ f(x) dx = ∫ 9k dx = 1

The integral of a constant function over its domain is simply the value of the constant times the length of the domain.

In this case, the length of the domain [−1, 1] is 2. Thus, we have:

∫ f(x) dx = 9k ∫ dx = 9k(2) = 18k

Now, we can set 18k equal to 1 and solve for k:
18k = 1
k = 1/18

Therefore, the value of k for which the given function f(x) = 9k on [−1, 1] is a probability density function is k = 1/18.

The solution to x' = jx using exp(jt) is x(t) = ce^(jt), where c is a constant.

We start by assuming that x(t) = ce^(jt), then taking its derivative we get x'(t) = c(j)e^(jt). We substitute these values into the equation x' = jx and get c(j)e^(jt) = jce^(jt). We can then divide both sides by ce^(jt) to get j = j, which is true. This means that our assumption of x(t) = ce^(jt) is valid, and the solution is x(t) = ce^(jt).

The exponential function e^(jt) is a complex-valued function that can be used to represent sinusoidal functions with angular frequency t. In this case, we use it to represent the solution to the differential equation x' = jx. By assuming that x(t) is of the form ce^(jt), we are essentially saying that the function x(t) is a sinusoidal function with angular frequency t, and that its amplitude is a constant c.

The solution to x' = jx using exp(jt) is x(t) = ce^(jt), where c is a constant. This solution represents a sinusoidal function with angular frequency t, and its amplitude is a constant c.

The area of the sector bounded by the arc GJ is 25.97 square feet

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

Diameter  = 23 feet

Also, we have

Central angle bounded by arc GJ = 1/16 * 360

So, we have

Central angle bounded by arc GJ = 22.5

The area of the sector bounded by the arc GJ is then calculated as

Area = Central angle/360 * πr²

This gives

Area = 22.5/360 * π * (23/2)²

Evaluate

Area = 25.97

Hence, the area of the sector bounded by the arc GJ is 25.97 square feet

The maximum velocity of the car is 0 m/s and the time t' when it stops is t' = -10/a when subjected to acceleration.

Given that the jet car is originally traveling at a velocity of 10 m/s and is subjected to acceleration, we need to determine the car's maximum velocity and the time t' when it stops.

We can use the equation of motion:
v = u + at

Where:
v = final velocity
u = initial velocity
a = acceleration
t = time

Let's assume that the car comes to a stop at time t' and the final velocity is 0 m/s.
0 = 10 + at'
t' = -10/a

Now, to determine the maximum velocity, we can use another equation of motion:
[tex]v^2 = u^2 + 2as[/tex]

Where:
s = distance

As the car stops, the distance traveled before coming to a stop will be:
[tex]s = ut' + (1/2)at'^2[/tex]

Substituting the value of t' in the above equation, we get:
[tex]s = 10(-10/a) + (1/2)a(-10/a)^2[/tex]
s = -50/a

Now, substituting the values of s, u, and a in the equation of motion, we get:
[tex]v^2 = 10^2 + 2a(-50/a)[/tex]
[tex]v^2 = 100 - 100\\v^2 = 0[/tex]

v = 0 m/s

Hence, the maximum velocity of the car is 0 m/s and the time t' when it stops is t' = -10/a.

The following propositions can be written: a) p → r (If you are liked by your friends, you will get a present). b) ¬p ↔ (¬q ∨ ¬r) (You do not get a present for your birthday if and only if either you do not remind your friends about your birthday or your friends do not like you).

a) To represent the proposition "If you are liked by your friends, you will get a present," we can use the conditional operator →. So, the proposition can be written as p → r, where p represents "You get a present for your birthday" and r represents "You are liked by your friends." This statement implies that if p is true (you get a present), then r must also be true (you are liked by your friends).

b) The proposition "You do not get a present for your birthday if and only if either you do not remind your friends about your birthday or your friends do not like you (or both)" involves the use of the biconditional operator ↔. Let's break it down:

¬p represents "You do not get a present for your birthday."

¬q represents "You do not remind your friends about your birthday."

¬r represents "Your friends do not like you."

Combining these propositions, we can write the statement as ¬p ↔ (¬q ∨ ¬r), which means that ¬p is true if and only if either ¬q or ¬r (or both) is true. This statement implies that if you do not get a present, it is because either you did not remind your friends about your birthday or your friends do not like you (or both).

The integral diverges, the series ∑(n = 2 to ∞) 5n ln(n) / n also divergent series.

To determine the convergence of the series ∑(n = 2 to infinity) 5n ln(n) / n, we can apply the Integral Test.

The Integral Test states that if f(x) is a positive, continuous, and decreasing function on the interval [n, ∞), and f(n) = aₙ, then the series  ∑(n = 2 to ∞) aₙ is convergent if and only if the integral ∫(n = 2 to ∞) f(x) dx is convergent.

In this case, let's consider f(x) = 5x ln(x) / x.

Taking the integral of f(x) from 2 to ∞:

∫(x = 2 to ∞) (5x ln(x) / x) dx = 5∫(x = 2 to ∞) ln(x) dx

Using integration by parts (u-substitution), let u = ln(x) and dv = dx:

∫(x = 2 to ∞) ln(x) dx = x ln(x) - ∫(x = 2 to ∞) x / x dx

= x ln(x) - ∫(x = 2 to ∞) 1 dx

= x ln(x) - x | (x = 2 to ∞)

= ∞ - 2 ln(2) - (2 ln(2) - 2)

= ∞

Since the integral diverges, the series ∑(n = 2 to infinity) 5n ln(n) / n also diverges.

Therefore, the series is divergent.
