a) To find the value of β that satisfies limt→[infinity]y(t) = 0, we can first find the general solution of the differential equation. So the value(s) of β for which the solution y(t) is never equal to 0 for all t is [tex]β ∈ (-∞, -2) U (-2/3, ∞)[/tex]

The characteristic equation is [tex]r^2 + r - 2 = 0[/tex], which has roots r = 1 and r = -2.

Therefore, the general solution is[tex]y(t) = c1e^t + c2e^-2t.[/tex]

Using the initial conditions y(0) = 2 and y'(0) = β, we can solve for the constants c1 and c2:

[tex]c1 + c2 = 2[/tex]

[tex]c1 - 2c2 = β[/tex]

Solving this system of equations, we get [tex]c1 = 2 - β/3[/tex] and [tex]c2 = β/3.[/tex]

Therefore, the solution is y(t) =[tex](2 - β/3)e^t[/tex] + [tex]β/3)e^-2t[/tex]. To satisfy limt→[infinity]y(t) = 0, we need the coefficient of e^t to be 0, which gives us 2 - β/3 = 0. Solving for β, we get β = 6.

So the value of β that satisfies limt→[infinity]y(t) = 0 is β = 6.

b) To find the value(s) of β for which the solution y(t) is never equal to 0 for all t, we can use the fact that the discriminant of the characteristic equation determines the nature of the roots.

In this case, the characteristic equation is r^2 + r - 2 = 0, which has roots r = 1 and r = -2. These are distinct real roots, so the general solution is y(t) = [tex]c1e^t + c2e^-2t.[/tex]

For y(t) differential equation to never be equal to 0 for all t, we need both constants c1 and c2 to be nonzero. Using the initial condition y(0) = 2, we get c1 + c2 = 2.

Using the second initial condition y'(0) = β, we get c1 - 2c2 = β.

Solving these equations, we get [tex]c1 = (2β + 4)/5[/tex] and [tex]c2 = (6 - β)/5.[/tex]

Therefore, y(t) is never equal to 0 for all t if and only if both c1 and c2 are nonzero, which is true if and only if the coefficients satisfy the inequality (2β + 4)(6 - β) ≠ 0. Solving this inequality, we get [tex]β ∈ (-∞, -2) U (-2/3, ∞).[/tex]

The mean of the binomial variable is 28 and the standard deviation is 2.72, given a probability of success of 0.7 with a total number of attempts of 40.

To calculate the mean (μ) and standard deviation (σ) of a binomial variable, we use the following formulas

μ = np

σ = sqrt(np × (1-p))

where n is the number of trials, and p is the probability of success for each trial.

In this case, the probability of success is 0.7, the number of trials is 40. So:

μ = 400.7 = 28

The surface whose equation is given by ρ = cos ϕ is a type of conical surface in the spherical coordinate system. In this equation, ρ represents the radial distance from the origin, and ϕ denotes the polar angle.

Explanation:

The surface described by the equation ρ = cos(ϕ) is a type of conical surface in the spherical coordinate system. Let's break down the explanation step by step:

Spherical Coordinate System: The spherical coordinate system is a three-dimensional coordinate system used to represent points in space using three parameters - radial distance (ρ), polar angle (ϕ), and azimuthal angle (θ). The radial distance ρ represents the distance from the origin (0,0,0) to a point in space, ϕ represents the polar angle measured from the positive z-axis (ranging from 0 to π), and θ represents the azimuthal angle measured from the positive x-axis in the xy-plane (ranging from 0 to 2π).

Equation ρ = cos(ϕ): The equation ρ = cos(ϕ) describes a relationship between the radial distance ρ and the polar angle ϕ. It specifies that for any given value of the polar angle ϕ, the radial distance ρ should be equal to the cosine of ϕ.

Conical Surface: In the context of the spherical coordinate system, a conical surface is a surface that forms a cone shape with its apex at the origin. The equation ρ = cos(ϕ) describes a conical surface because it specifies that the radial distance ρ is determined by the cosine of the polar angle ϕ.

Shape of the Surface: As the polar angle ϕ varies, the equation ρ = cos(ϕ) determines the radial distance ρ at each point on the surface. Since the radial distance is only determined by the cosine of the polar angle, the surface will have a conical shape. Specifically, the surface will form a cone with its apex at the origin and its base expanding outward as ϕ increases from 0 to π. The radius of the base of the cone will vary with the value of ϕ, as determined by the cosine function. When ϕ = 0, the base of the cone will have its maximum radius, equal to 1 (since cos(0) = 1), and as ϕ increases towards π, the radius of the base will decrease until it reaches its minimum value of -1 (since cos(π) = -1). The surface will extend infinitely in the positive and negative z-directions.

In conclusion, the surface described by the equation ρ = cos(ϕ) in the spherical coordinate system is a type of conical surface, forming a cone with its apex at the origin and its base expanding outward as the polar angle ϕ increases, with the radius of the base varying based on the cosine of ϕ.

Answer:

4092

Step-by-step explanation:

We can see that this is a geometric sequence where the first term is 4 and the common ratio is 2. We can use the formula for the sum of a geometric sequence to find the sum of this series:

sum = a(1 - r^n) / (1 - r)

where a is the first term, r is the common ratio, and n is the number of terms.

We need to find n, the number of terms. We can use the formula for the nth term of a geometric sequence:

a_n = a * r^(n-1)

We want to find the value of n when a_n = 2048:

2048 = 4 * 2^(n-1)

512 = 2^(n-1)

n-1 = log2(512) = 9

n = 10

So there are 10 terms in the series. Now we can use the formula for the sum of a geometric sequence:

sum = a(1 - r^n) / (1 - r)

sum = 4(1 - 2^10) / (1 - 2)

sum = 4(1 - 1024) / (-1)

sum = 4(1023)

sum = 4092

Rounding to the nearest hundredth, the sum is approximately 4092.00.

Answer:

Sum=8188

Step-by-step explanation:

This is a geometric series with a first term of 4 and a common ratio of 2. The formula for the sum of a geometric series is:

Sn​=1−ra(1−rn)​

where a is the first term, r is the common ratio and n is the number of terms. In this case, we have:

S11​=1−24(1−211)​

Simplifying, we get:

S11​=−14(−2047)​

S11​=8188

Therefore, the sum of the series is 8188.

or

[tex]dy/dx = [(5x) / (5x^2 + 9y^2)] + [(9y) / (5x^2 + 9y^2)] * y'[/tex]

To find y', we need to use the chain rule of differentiation because we have a composite function (i.e., the natural logarithm function is applied to a function of x and y).

Let's start by applying the chain rule:

[tex]y' = d/dx [ln(5x^2 + 9y^2)]y' = (1 / (5x^2 + 9y^2)) * d/dx [5x^2 + 9y^2][/tex]

Now, we need to apply the chain rule to find the derivative of[tex]5x^2 + 9y^2[/tex]with respect to x:

[tex]d/dx [5x^2 + 9y^2] = d/dx [5x^2] + d/dx [9y^2][/tex]

[tex]d/dx [5x^2] = 10x[/tex]

[tex]d/dx [9y^2] = 18y * dy/dx[/tex]

(Note that we used the chain rule again to find [tex]dy/dx.)[/tex]

Substituting these derivatives into the expression for y', we get:

[tex]y' = (1 / (5x^2 + 9y^2)) * (10x + 18y * dy/dx)[/tex]

Finally, we can simplify this expression by solving for dy/dx:

[tex]y' = (10x + 18y * dy/dx) / (5x^2 + 9y^2)[/tex]

Multiplying both sides by (5x^2 + 9y^2), we get:

[tex]y' * (5x^2 + 9y^2) = 10x + 18y * dy/dx[/tex]

Solving for dy/dx, we obtain:

[tex]dy/dx = (y' * (5x^2 + 9y^2) - 10x) / 18y[/tex]

Therefore, the derivative of y with respect to x is:

To prove that δqrev in equation 6.1 is not an exact differential, we can use the criterion developed in math chapter d. The criterion states that if a differential equation is exact, then its partial derivatives must satisfy the condition ∂M/∂y = ∂N/∂x.

In equation 6.1, δqrev is defined as δqrev = TdS. If we express δqrev in terms of its partial derivatives, we get:
∂(δqrev)/∂S = T
∂(δqrev)/∂T = S

Now, let's calculate the partial derivatives of ∂(∂(δqrev)/∂S)/∂T and ∂(∂(δqrev)/∂T)/∂S:
∂(∂(δqrev)/∂S)/∂T = ∂T/∂S = 0 (since T does not depend on S)
∂(∂(δqrev)/∂T)/∂S = ∂S/∂T = 0 (since S does not depend on T)

Since these partial derivatives are equal to zero, we can conclude that δqrev is not an exact differential, as it does not satisfy the condition ∂M/∂y = ∂N/∂x.

Therefore, we have proven that δqrev in equation 6.1 is not an exact differential.

The given function is f(x) = (x+3)^4 * (x-4)^3 * (x-6)^6. The interval on which f(x) is increasing is (4, ∞).

To determine the intervals on which f(x) is increasing or decreasing, we need to analyze the sign of f'(x), the first derivative of f(x). In this case, f'(x) can be calculated using the product and chain rules of differentiation:

f'(x) = 4(x+3)^3 * (x-4)^3 * (x-6)^6 + 3(x+3)^4 * (x-4)^2 * (x-6)^6 + 6(x+3)^4 * (x-4)^3 * (x-6)^5

Simplifying f'(x) and factoring out common terms, we get:

f'(x) = (x+3)^3 * (x-4)^2 * (x-6)^5 * [4(x-6) + 3(x+3)(x-4) + 6(x-4)]

We can now analyze the sign of f'(x) for different values of x:

Thus, the interval on which f(x) is increasing is (4, ∞).

Thus, the area of new kite with its diagonal doubled is found as: 140 sq. cm.

The area a kite encloses is known as its area of flight. A quadrilateral with two sets of neighbouring sides that are equal is referred to as a kite. A kite is made up of four angles, four sides, and two diagonals.

The product of a lengths of a kite's diagonals divides its area in half.

The area of the kite ABCD = 35 cm square.

The formula for the area of kite = 1/2*(d)*(D)

d - length of small diagonal

D - length of large diagonal.

Then,

35 =  1/2*(d)*(D)

(d)*(D) = 35*2

(d)*(D) = 70 cm sq.  ..eq 1

Now, the length of diagonals of new kite are doubles that is 2d and 2D.

Area of new kite = 1/2 *(2d)*(2D)

Area of new kite = 1/2 *4*(d)*(D)

Area of new kite = 2 *(d)*(D)

Put the value of (d)*(D) from eq 1.

Area of new kite = 2*70

Area of new kite = 140 sq. cm

Thus, the area of the new kite with its diagonal doubled is found as: 140 sq. cm.
