w₁ = (-1 + √7) / 2 and w₂ = (-1 - √7) / 2. To solve the quadratic equation 4w² + 4w - 27 = 0, we can use the quadratic formula:

w = (-b ± √(b² - 4ac)) / (2a)

In this case, a = 4, b = 4, and c = -27. Plugging these values into the quadratic formula, we get:

w = (-4 ± √(4² - 4(4)(-27))) / (2(4))

w = (-4 ± √(16 + 432)) / 8

w = (-4 ± √448) / 8

w = (-4 ± √(16 * 28)) / 8

w = (-4 ± 4√7) / 8

w = (-1 ± √7) / 2

So, the solutions to the equation are:

w₁ = (-1 + √7) / 2

w₂ = (-1 - √7) / 2

Therefore, w₁ = (-1 + √7) / 2 and w₂ = (-1 - √7) / 2.

The solution to the initial value problem is:[tex]y(t) = -e^(-t) + 2e^(-3t) + te^(2t)[/tex]

The given initial value problem is as follows

[tex]:y'' - 2y- 3y' = 3te^(2t), y(0) = 1, y'(0) = 0[/tex]

We can use the method of undetermined coefficients to solve this initial value problem.

The complementary function for the differential equation is given by:

[tex]ycf(t) = c1 e^(-t) + c2 e^(-3t)[/tex]

Now, let us calculate the particular integral. The given forcing term is:

[tex]3te^(2t).[/tex]

We can assume that the particular integral is of the form:[tex]y(t) = (A t + B)e^(2t)[/tex]

where A and B are constants that are to be determined.

On substituting the values in the given differential equation, we get:[tex]3te^(2t) = y'' - 2y - 3y'[/tex]

Now, let us differentiate y(t) to get:

[tex]y'(t) = Ae^(2t) + (At + B)(2e^(2t)) \\= 2Ae^(2t) + 2Ate^(2t) + 2Be^(2t)[/tex]

On substituting the values of y(t) and y'(t) in the given differential equation, we get:

[tex]3te^(2t) = (4A + 2B - 6At - 3Ate^(2t) - 3Be^(2t))[/tex]

On equating the coefficients of t and the constant terms, we get:

[tex]4A + 2B = 0-6A \\= 03B \\= 3[/tex]

On solving the above equations, we get: A = 0 and B = 1

Therefore, the particular integral is given by: [tex]yp(t) = te^(2t)[/tex]

The general solution is given by:

[tex]y(t) = ycf(t) + yp(t) \\= c1 e^(-t) + c2 e^(-3t) + te^(2t)[/tex]

We can find the values of c1 and c2 using the initial conditions: [tex]y(0) = c1 + c2 = 1y'(0) = -c1 - 3c2 + 2 = 0[/tex]

On solving the above equations, we get: [tex]c1 = -1 and c2 = 2[/tex]

The probability that less than 3 people will make a purchase from the given data is 0.999.

Given: An e-commerce website claims that % of people who visit the site make a purchase. A random sample of 15 is taken out of those who visited the website. We need to find the probability that less than 3 people will make a purchase.

We can solve this problem by using the binomial probability formula.

The formula for the binomial probability is:

P (X = k) = C(n, k) * p^k * (1 - p)^(n-k)

where n is the sample size, k is the number of successes, p is the probability of success, and C(n, k) is the binomial coefficient.

Here, the probability of making a purchase is not given, so we cannot directly use the formula. However, we can assume that the probability of making a purchase is small (say 0.01) and use the Poisson approximation to the binomial distribution.

The formula for Poisson approximation is:

P(X = k) = (e^(-λ) * λ^k) / k!

where λ = np is the mean and variance of the binomial distribution.

Here, n = 15 and p = %. So, λ = np = 15 * % = 0.15.

Now, we can find the probability of less than 3 people making a purchase:

P(X < 3) = P(X = 0) + P(X = 1) + P(X = 2)

P(X < 3) ≈ (e^(-0.15) * 0.15^0) / 0! + (e^(-0.15) * 0.15^1) / 1! + (e^(-0.15) * 0.15^2) / 2!

P(X < 3) ≈ 0.999.

Hence, the probability that less than 3 people will make a purchase from the given data is 0.999.

The results of the BCD addition for the two given numbers are a) 1001 0100 + 0110 0111 = 1111 1011 and b) 1001 1000 + 0001 0010 = 1010 1010

The first step in BCD addition is to add the two numbers together, just like you would add any two binary numbers. However, there are a few special cases to watch out for. If the sum of two digits is greater than 9, you need to add 6 to the sum. This is because the BCD code only has 10 possible values, so any number greater than 9 will be invalid.

In the first example, the sum of the first two digits is 10, so we add 6 to get 16. The sum of the next two digits is also 10, so we add 6 to get 16. The final digit is 1, so the overall sum is 1111 1011.

In the second example, the sum of the first two digits is 11, so we add 6 to get 17. The sum of the next two digits is 10, so we add 6 to get 16. The final digit is 0, so the overall sum is 1010 1010.

To verify the results, we can convert the BCD numbers to decimal and add them together. In the first example, the BCD number 1001 0100 is equal to 176 in decimal. The BCD number 0110 0111 is equal to 103 in decimal. When we add these two numbers together, we get 279 in decimal. This is the same as the BCD number 1111 1011.

In the second example, the BCD number 1001 1000 is equal to 160 in decimal. The BCD number 0001 0010 is equal to 10 in decimal. When we add these two numbers together, we get 170 in decimal. This is the same as the BCD number 1010 1010.

A 2 x 2 matrix A such that -3 [B] and B - -3 - are eigenvectors of A with eigenvalues 5 and -1, respectively is given by\[A is (5 - 3)(-3 - 3)\]\[A = 2(-6)\]\[A = -12\]

Thus, the matrix A is -\[A = \begin{bmatrix}-12 & 0\\ 0 & -12\end{bmatrix}\]  we can choose A to be any matrix.

Step-by-step answer:

We are given that -3 [B] and B - -3 - are eigenvectors of A with eigenvalues 5 and -1, respectively. Let v1 be the eigenvector corresponding to the eigenvalue 5.

Thus, Av1 = 5v1. Also, we have

v1 = -3[B],

so Av1 = A(-3[B])

= -3(A[B]).

Thus,-3(A[B]) = 5(-3[B]).\[AB

= -\frac{5}{3} B\]

Thus B is an eigenvector of A with the eigenvalue -5/3.Similarly, let v2 be the eigenvector corresponding to the eigenvalue -1.

Thus, Av2 = -v2. Also, we have

v2 = B - (-3)[B]

= 4[B].

Thus Av2 = A(4[B])

= 4(A[B]).

Thus,\[AB = -\frac{1}{4}B\]

Thus, B is an eigenvector of A with the eigenvalue -1/4. To solve for A, we can solve the system of equations given by\[AB = -\frac{5}{3}B\]\[AB = -\frac{1}{4}B\]

Multiplying the first equation by -4/15 and the second equation by -15/4, we get\[\frac{4}{15}AB = B\]\[-\frac{15}{4}AB

= B\]

Multiplying the two equations, we get\[(-1) = \det(AB)\]

Using the formula for the determinant of a product of matrices, we get\[\det(A)\det(B) = -1\]

Since B is nonzero, we have \[\det(B) \neq 0\].

Thus,\[\det(A) = -\frac{1}{\det(B)}\]

Since A is a 2 x 2 matrix, we have\[\det(A) = ad - bc\]where

A = [a b; c d].

Thus,\[-\frac{1}{\det(B)} = ad - bc\]

We know that B is an eigenvector of A, so AB = kB, where k is the eigenvalue of B. Substituting this in the expression for det(A), we get\[-\frac{1}{k} = ad - k\]

Using the eigenvalues of B, we get\[\frac{5}{3} = ad + \frac{5}{3}\]\[\frac{1}{4}

= ad + \frac{1}{4}\]

Solving for a and d, we get a = -6 and

d = -6.

Thus, A is given by\[A = \begin{bmatrix}-6 & 0\\ 0 & -6\end{bmatrix}\]

Note: Here, we are assuming that B is nonzero. If B is the zero vector, then it cannot be an eigenvector of any matrix except the zero matrix. In this case, we can choose A to be any matrix.

Considering the equation f(x, y) = y⁴/x, the directional derivative of f in the direction of u at the point p(1,3) is -183/39.

At the point p(1,3), the equation is calculated to determine the directional derivative in the direction of the vector u = 1 3 2i + 5j. Therefore, the directional derivative is given by:`Duf(p) = ∇f(p) · u`

We first need to calculate the gradient of the function:`∇f(x, y) = <∂f/∂x, ∂f/∂y>`Differentiating f(x, y) partially with respect to x and y gives:```
∂f/∂x = -y⁴/x²
∂f/∂y = 4y³/x
```Therefore, the gradient of f is:`∇f(x, y) = <-y⁴/x², 4y³/x>`At the point p(1,3), the gradient of f is:`∇f(1,3) = <-81, 12>`

We need to normalize the vector u to get the unit vector in the direction of u.`||u|| = √(1² + 3² + 2² + 5²) = √39`

Therefore, the unit vector in the direction of u is:`u/||u|| = (1/√39) 3/√39 2i/√39 + 5/√39j`

Therefore, the directional derivative is:`Duf(p) = ∇f(p) · u = <-81, 12> · (1/√39) 3/√39 2i/√39 + 5/√39j`

Evaluating this expression gives:`Duf(p) = (-243 + 60)/39 = -183/39`

Therefore, the directional derivative of f in the direction of u at the point p(1,3) is -183/39.

To find the variance of the random variable X representing the total number of hours a family runs a vacuum cleaner in a year, we need to calculate the weighted average of the squared differences between X and its mean.

The given density function for X can be split into two intervals: 8 < x < 10 and 10 ≤ x < 12. In the first interval, the density function is (1/4)(x - 8), while in the second interval, it is 1 - 1/4(x - 8). Outside of these intervals, the density function is 0.

To calculate the variance, we first need to find the mean of X. The mean, denoted as μ, can be obtained by integrating X multiplied by its density function over the entire range. Since the density function is 0 outside the intervals (8, 10) and (10, 12), we only need to integrate within those intervals. The mean, in this case, will be (1/4)∫[8,10] x(x - 8)dx + ∫[10,12] x(1 - 1/4(x - 8))dx.

Once we have the mean, we can calculate the variance using the formula Var(X) = E[(X - μ)²]. We integrate (x - μ)² multiplied by the density function over the same intervals to find the variance. Finally, we obtain the result by evaluating Var(X) = ∫[8,10] (x - μ)²(1/4)(x - 8)dx + ∫[10,12] (x - μ)²(1 - 1/4(x - 8))dx.

Therefore, Jessica's rate is 12.5 miles per hour.

To find Jessica's rate in miles per hour, we need to determine the total distance she traveled and the total time it took her.

Given that Jessica is walking home, we can consider the distance from her friend's house to her home as the positive direction. Let's denote this distance as "d" in miles.

From the information provided, we know that Jessica is 1.1 miles from home after 2 minutes and 0.6 miles from home after 12 minutes.

Let's set up a proportion to find the total distance she traveled (d) in miles:

(d - 0) / (12 - 2) = (1.1 - 0.6) / (2 - 0)

Simplifying the proportion:

d / 10 = 0.5 / 2

Cross-multiplying:

2d = 10 * 0.5

2d = 5

d = 5 / 2

So, Jessica traveled a total distance of 2.5 miles.

Now, let's find the total time it took her. The time from her friend's house to her home can be represented as "t" in hours.

We know that Jessica took 12 minutes to travel 0.6 miles. Let's convert this to hours:

t = 12 minutes / 60 (conversion to hours)

t = 0.2 hours

Therefore, Jessica took a total of 0.2 hours to travel from her friend's house to her home.

The linear transformation T : R⁴ → R⁴ represented by the matrix M(T) is given as:

M(T) = | 0 0 0 7 |

         | -1 0 0 2 |

         | 0 0 1 -1 |

         | 0 0 0 0 |

The linear transformation T can be interpreted based on its matrix representation. The matrix M(T) provides the coefficients for transforming a 4-dimensional vector (x, y, z, t) into a new 4-dimensional vector (x', y', z', t'). In this case, T maps the input vector (x, y, z, t) to the output vector (x', y', z', t') as follows:

x' = 7t

y' = -x + 2t

z' = y - z

t' = 0

Therefore, the transformation T scales the t-component by a factor of 7, sets the x'-component as -x + 2t, the z'-component as y - z, and the t'-component as 0.

For the bases of Ker(T) and Im(T):

The kernel of T, Ker(T), consists of all vectors (x, y, z, t) in R⁴ that are mapped to the zero vector (0, 0, 0, 0) under the transformation T. In this case, the kernel of T can be determined by finding the solutions to the homogeneous system of equations given by T(x, y, z, t) = (0, 0, 0, 0). The basis for Ker(T) can be obtained by expressing the solutions in terms of linearly independent vectors.

The image of T, Im(T), consists of all possible output vectors (x', y', z', t') that can be obtained by applying the transformation T to any input vector (x, y, z, t) in R⁴. The basis for Im(T) can be found by determining a set of linearly independent vectors that span the image of T.

Step 1: Let's solve the third equation, x + x = 4 by rearranging it to obtain the values of x and y as follows:

2x = 4x = 2

Substituting the value of x in the third equation, we get:

y = 4 - 2 = 2

Step 2: Plot the points (2, 2) and (0, 4) on the xy-plane.

Step 3: Now, let's solve the second equation, z0 = 2x + y for different values of x and y.

We can represent this equation in terms of x and z0 as follows:z0 = 2x + yz0 = 2x + (4 - x)z0 = x + 4

The above equation represents a straight line with slope 1 and y-intercept 4.

Plot this line on the xy-plane.

Step 4: Similarly, let's solve the first equation, z = 0.1x + y for different values of x and y.

We can represent this equation in terms of x and z as follows:z = 0.1x + yz = 0.1x + (4 - x)z = 4 - 0.9x

The above equation represents a straight line with slope -0.9 and y-intercept 4.

Plot this line on the xy-plane.

Step 5: The optimal solution occurs at the corner points of the feasible region.

Therefore, we need to evaluate the function z at each of these corner points to find the maximum value of z.

Corner point A: (0, 4)z = 0.1(0) + 4 = 4Corner point B: (2, 2)z = 0.1(2) + 2 = 0.4 + 2 = 2.4

Corner point C: (2, 0)z = 0.1(2) + 0 = 0.2

Therefore, the maximum value of z is 4, which occurs at the corner point A (0, 4).

Hence, the required maximum value of the function is z = 4.

The generating function for the sequence an = 3 + 5n is F(t) = 3/[tex](1-t)^{2}[/tex]. The sequence generated by the function F(t) = 1 + 12[tex]t^{3}[/tex] is given by an = 12[tex]n^{3}[/tex] + 1.

a) To find the generating function for the sequence an = 3 + 5n, we can start by expressing the terms of the sequence in the form of a power series. We have an = 3 + 5n, which can be rewritten as an = 5n + 3. Now, we can write the generating function as F(t) = Σ(5n + 3)[tex]t^{n}[/tex], where Σ denotes the summation over all values of n. Separating the terms, we get F(t) = Σ(5n)[tex]t^{n}[/tex] + Σ(3)[tex]t^{n}[/tex]. Using the properties of generating functions, we know that the generating function for an = n[tex]t^{n}[/tex] is given by Nt/[tex](1-t)^{2}[/tex], where N is the coefficient of t. Applying this formula, we have the first term as 5t/(1-t)^2 and the second term as 3/(1-t). Combining these two terms, we get F(t) = 5t/[tex](1-t)^{2}[/tex] + 3/(1-t). Simplifying further, we obtain F(t) = 3/[tex](1-t)^{2}[/tex].

b) For the given generating function F(t) = 1 + 12[tex]t^{3}[/tex], we want to find the sequence it generates. To do this, we can expand the function in a power series. Expanding the terms, we have F(t) = 1 + 12[tex]t^{3}[/tex] = 1 + 12[tex]t^{3}[/tex] + 0[tex]t^{4}[/tex] + 0t^5 + ... As we can see, the coefficients of the terms are in the form of an = 12[tex]n^{3}[/tex] + 1. Therefore, the sequence generated by the function F(t) = 1 + 12[tex]t^{3}[/tex] is given by an = 12[tex]n^{3}[/tex] + 1.

(a) The center is (3, -3), the vertices are (6, -3) and (0, -3),  transverse-axis is horizontal-line passing through center (3, -3), and asymptotes are y = 3x - 12; y = -3x + 6.

(b) The graph of the hyperbola is shown below.

Part (a) : To find the center, vertices, transverse-axis, and asymptotes of the hyperbola, we can rewrite the given equation in standard form for a hyperbola : (y - k)²/a² - (x - h)²/b² = 1,

Comparing this form with the given equation:

(y + 3)² - 9(x - 3)² = 9

We see that center of hyperbola is (h, k) = (3, -3),

To determine the values of "a" and "b", we divide both sides of equation by 9 to get standard form,

(y + 3)²/9 - (x - 3)²/1 = 1,

From this, we identify that a = √9 = 3 and b = √1 = 1,

The vertices are located at (h ± a, k), which gives the coordinates (3 ± 3, -3), so the vertices are (6, -3) and (0, -3),

The "transverse-axis" is the line passing through the center and perpendicular to asymptotes. In this case, the transverse-axis is a horizontal line passing through the center (3, -3).

The equation of the asymptotes can be determined using the formula : y = ± (a/b) × (x - h) + k

In this case, a = 3 and b = 1. Substituting the values, we have:

y - (-3) = ± (3/1) × (x - 3)

y + 3 = ± 3(x - 3)

y + 3 = ± 3x - 9

Simplifying, we get two equations for the asymptotes:

y = 3x - 12

y = -3x + 6

Part (b) : To graph the hyperbola using the vertices and asymptotes, we  plot the center (3, -3), the vertices (0, -3) and (6, -3), and then draw the asymptotes.

The center is a point on the graph, and the vertices represent the endpoints of the transverse-axis. The asymptotes are the dashed lines that intersect at the center and pass through the vertices.

The value of x that satisfies the equation 45 - 3x = 1256 is approximately -403.6666667.

To solve the equation 45 - 3x = 1256, we want to isolate the variable x on one side of the equation. This can be done by performing a series of mathematical operations that maintain the equality of the equation.

Start by combining like terms on the left side of the equation. The constant term, 45, remains as it is, and we have -3x on the left side. The equation becomes:

-3x + 45 = 1256

To isolate the variable x, we need to move the constant term to the right side of the equation. Since the constant term is positive, we'll subtract 45 from both sides of the equation to eliminate it from the left side:

-3x + 45 - 45 = 1256 - 45

Simplifying, we have:

-3x = 1211

To solve for x, we want to isolate the variable on one side of the equation. Since the variable x is currently being multiplied by -3, we can isolate it by dividing both sides of the equation by -3:

(-3x) / -3 = 1211 / -3

The -3 on the left side cancels out, leaving us with:

x = -403.6666667

These terms form the Taylor polynomial of [tex]f(x) = 2^x[/tex] about a = 2 with the first four non-zero terms.

The first four non-zero terms of the Taylor polynomial of the function[tex]f(x) = 2^x[/tex] about a = 2 can be found by taking derivatives of the function.

The Taylor polynomial approximates a function by using a polynomial expansion around a specific point. In this case, we are given the function [tex]f(x) = 2^x[/tex] and asked to find the Taylor polynomial around a = 2.

To find the first four non-zero terms of the Taylor polynomial, we need to evaluate the function and its derivatives at the point a = 2. Let's start by calculating the first derivative. The derivative of [tex]f(x) = 2^x[/tex] with respect to x is [tex]f'(x) = (ln(2)) * (2^x)[/tex]. Evaluating f'(2), we get [tex]f'(2) = (ln(2)) * (2^2) = 4ln(2)[/tex].

Next, we find the second derivative by differentiating f'(x) with respect to x. The second derivative, denoted as f''(x), is equal to [tex](ln(2))^2 * (2^x)[/tex]. Evaluating f''(2), we get [tex]f''(2) = (ln(2))^2 * (2^2) = 4(ln(2))^2[/tex].

Continuing this process, we differentiate f''(x) to find the third derivative f'''(x). Taking the derivative yields[tex]f'''(x) = (ln(2))^3 * (2^x)[/tex]. Evaluating f'''(2), we get[tex]f'''(2) = (ln(2))^3 * (2^2) = 4(ln(2))^3[/tex].

Finally, we differentiate f'''(x) to find the fourth derivative f''''(x). The fourth derivative is [tex]f''''(x) = (ln(2))^4 * (2^x)[/tex]. Evaluating f''''(2), we get[tex]f''''(2) = (ln(2))^4 * (2^2) = 4(ln(2))^4[/tex].

Therefore, the first four non-zero terms of the Taylor polynomial of [tex]f(x) = 2^x[/tex] about a = 2 are:

[tex]f(2) + f'(2)(x - 2) + (1/2!)f''(2)(x - 2)^2 + (1/3!)f'''(2)(x - 2)^3 + (1/4!)f''''(2)(x - 2)^4[/tex].

Substituting the calculated values, we have:

[tex]2 + 4ln(2)(x - 2) + 2(ln(2))^2(x - 2)^2 + (4/3)(ln(2))^3(x - 2)^3 + (1/6)(ln(2))^4(x - 2)^4[/tex].

To apply the power rule for differentiation to the function f(x, y) = 5x^4y^3 + 3x^2y + 4x + 5y, we differentiate each term with respect to x while treating y as a constant.

The power rule states that if we have a term of the form x^n, where n is a constant, then the derivative with respect to x is given by nx^(n-1).

Let's differentiate each term one by one:

For the term 5x^4y^3, the power rule gives us:

d/dx (5x^4y^3) = 20x^3y^3.

For the term 3x^2y, the power rule gives us:

d/dx (3x^2y) = 6xy.

For the term 4x, the power rule gives us:

d/dx (4x) = 4.

For the term 5y, y is a constant with respect to x, so its derivative is zero.

Putting it all together, we have:

fx(x, y) = 20x^3y^3 + 6xy + 4.

Therefore, the derivative of the function f(x, y) with respect to x is fx(x, y) = 20x^3y^3 + 6xy + 4.

a) Since W satisfies all three conditions, it is a linear subspace of V.

b) Since W satisfies all three conditions, it is a linear subspace of V.

a) To check if the set W = {[0, y, z] : yz = 0} is a linear subspace of V = R³, we need to verify three conditions: closure under addition, closure under scalar multiplication, and containing the zero vector.

Closure under addition: Let's consider two vectors [0, y₁, z₁] and [0, y₂, z₂] from W. Their sum is [0, y₁ + y₂, z₁ + z₂]. We see that (y₁ + y₂)(z₁ + z₂) = y₁z₁ + y₂z₂ + y₁z₂ + y₂z₁ = 0 + 0 + y₁z₂ + y₂z₁ = y₁z₂ + y₂z₁ = 0. Therefore, the sum is also in W.

Closure under scalar multiplication: For any scalar k and vector [0, y, z] from W, k[0, y, z] = [0, ky, kz]. Since ky * kz = 0 * kz = 0, the scalar multiple is in W.

Containing the zero vector: The zero vector [0, 0, 0] is in W because 0 * 0 = 0.

Since W satisfies all three conditions, it is a linear subspace of V.

b) To check if the set W = {[x, y, z] : x + 3y = y - 2z = 0} is a linear subspace of V = R³, we again need to verify the closure under addition, closure under scalar multiplication, and containing the zero vector.

Closure under addition: Let's consider two vectors [x₁, y₁, z₁] and [x₂, y₂, z₂] from W. Their sum is [x₁ + x₂, y₁ + y₂, z₁ + z₂]. We need to check if (x₁ + x₂) + 3(y₁ + y₂) = (y₁ + y₂) - 2(z₁ + z₂) = 0. If we substitute the given equations, we can see that both conditions are satisfied. Therefore, the sum is also in W.

Closure under scalar multiplication: For any scalar k and vector [x, y, z] from W, k[x, y, z] = [kx, ky, kz]. If we substitute the given equations, we can see that the resulting vector also satisfies the equations, so the scalar multiple is in W.

Containing the zero vector: The zero vector [0, 0, 0] satisfies the given equations, so it is in W.

Since W satisfies all three conditions, it is a linear subspace of V.
