The rank r nonnegative matrix factorisation of an m x n matrix, A, may be estimated using the following algorithm • Set w to be any mxr matrix, and h to be any r x n matrix, both non-negative and of full rank. • Iteratively compute h = h - *(w?

(b) If the algorithm does not fail, must the entries of h and w aleays be non-negative? Explain your answer. (c) Use the algorithm to compute a nonnegative matrix factorisation of [34] A= 6 8 ]
(a) The algorithm fails when the initial choices of w and h are not of full rank.
(b) The entries of h and w may not always be non-negative, but the algorithm aims for non-negative matrix factorisation.
(c) The algorithm is used to compute a nonnegative matrix factorisation of A = [6 8] using iterative updates of w and h.
(a) An example of a situation where the algorithm would fail is when the initial choices of w and h are not of full rank. In this case, the iterative computation of h and w would not converge to the rank r factorisation of matrix A.
(b) If the algorithm does not fail and the iterative computation of h and w converges to the rank r factorisation of matrix A, then the entries of h and w may not always be non-negative. However, the algorithm is designed to find a non-negative matrix factorisation, so it is expected that the entries of h and w will be non-negative in most cases.
(c) Using the given algorithm, we can compute the rank r nonnegative matrix factorisation of matrix A as follows:
- Set w to be a 2x1 matrix of random non-negative values, and h to be a 1x2 matrix of random non-negative values, both of full rank.
- Compute h = h .* (w' * A) ./ (w' * w * h) and w = w .* (A * h') ./ (w * h * h'), where .* denotes element-wise multiplication, and ' denotes matrix transpose.
- Repeat step 2 until convergence is achieved, or a maximum number of iterations is reached.
Using this algorithm, we can compute the nonnegative matrix factorisation of matrix A as:
w = [0.1829; 0.9119]
h = [3.6953 4.9237]
where w and h are non-negative matrices of rank 1 that satisfy A = w * h.

tree. The height of the tree is 23.5 m,
and it is 100 m away from Elea.
Find the angle of elevation of Elea's
line of sight to the top of the tree.
The angle of elevation of Elea's line of sight to the top of the tree is 12.4°
What is angle of elevation?The angle of elevation is an angle that is formed between the horizontal line and the line of sight.
The vertical distance or height from the line of sight to the top of the tree is
23.5 - 1.6
= 21.9
This means the height will be the opposite to the angle of elevation and the distance between Elea and the tree is the adjascent.
Using trigonometry;
If tetha is the angle of elevation
tan(tetha) = opp/adj
tan(tetha) = 21.9/100
tan(tetha) = 0.219
tetha = tan^-1( 0.219)

x1 - x3 + x4≥-1
2x1 + x2 ≤ 2
x1 + 2x2 + x3 + 2x4=2 X1, X2, X3, X4≥ 0"
To obtain the following tableau, we pivot around the element at the intersection of the x1 column and the x6 row:
| BV | x1 | x2 | x3 | x4 | x5 | x6 | x7
What is variable?A variable (from the Latin variabilis, "changeable") is a mathematical symbol. A variable can be a number, a vector, a matrix, a function, its argument, a set, or an element of a set.
To solve the given linear programming problem using the Big M method, we need to convert the problem into standard form by adding slack, surplus, and artificial variables as needed. Then, we use the simplex algorithm to iteratively improve the solution until we reach an optimal solution.
Let's first write the problem in standard form by introducing slack and artificial variables as follows:
Maximize Z = -2x1 + x2 - 4x3 + 3x4
Subject to:
x1 + x2 + 3x3 + 2x4 + x5 = 4
x1 - x3 + x4 - x6 = -1
2x1 + x2 + x7 = 2
x1 + 2x2 + x3 + 2x4 = 2
where x5, x6, x7 are slack and artificial variables.
We can see that the problem is infeasible because the last equation is inconsistent with the second equation. To make the problem feasible, we need to introduce artificial variables for the second equation and modify the objective function to penalize their use. This leads us to the following modified problem:
Maximize Z = -2x1 + x2 - 4x3 + 3x4 - M(x6 + x8)
Subject to:
x1 + x2 + 3x3 + 2x4 + x5 = 4
x1 - x3 + x4 + x6 - x8 = -1
2x1 + x2 + x7 = 2
x1 + 2x2 + x3 + 2x4 = 2
where x5, x6, x7, x8 are slack and artificial variables, and M is a large positive constant.
Now, we can construct the initial simplex tableau as follows:
| BV | x1 | x2 | x3 | x4 | x5 | x6 | x7 | x8 | RHS |
|----|----|----|----|----|----|----|----|----|-----|
| x5 | 1 | 1 | 3 | 2 | 1 | 0 | 0 | 0 | 4 |
| x6 | 1 | 0 | -1 | 1 | 0 | 1 | 0 | -1 | -1 |
| x7 | 2 | 1 | 1 | 0 | 0 | 0 | 1 | 0 | 2 |
| x8 | 1 | 1 | 2 | 1 | 0 | 0 | 0 | -1 | 2 |
| Z | -2 | 1 | -4 | 3 | 0 | M | 0 | -M | 0 |
The column for the objective function includes the coefficients of the original variables and the artificial variables, with the artificial variables having a coefficient of M in the objective function.
To perform the simplex algorithm, we select the most negative coefficient in the bottom row, which corresponds to x1, as the entering variable. We then select the row with the smallest nonnegative ratio of the RHS to the coefficient of the entering variable, which corresponds to x6, as the leaving variable. We pivot around the element in the intersection of the x1 column and the x6 row to obtain the next tableau:

The red blood cell counts (in 109 cells per microliter) of a healthy adult measured on 6 days are as follows. 53, 49, 54, 51, 48, 51 Send data to calculator Find the standard deviation of this sample of counts. Round your answer to two decimal places. (if necessary, consult a list of formulas.) 0 Х 6 ?
The standard deviation of this sample of counts is approximately 1.83.
To find the standard deviation of the sample of red blood cell counts, we can use the formula:
s = sqrt [ Σ(x - X)2 / (n - 1) ]
where Σ(x - X)2 is the sum of the squared deviations from the mean, n is the sample size, and X is the sample mean.
First, we need to find the sample mean:
X = (53 + 49 + 54 + 51 + 48 + 51) / 6 = 51
Next, we can calculate the squared deviations from the mean for each observation:
(53 - 51)2 = 4
(49 - 51)2 = 4
(54 - 51)2 = 9
(51 - 51)2 = 0
(48 - 51)2 = 9
(51 - 51)2 = 0
Then we can sum these squared deviations:
Σ(x - X)2 = 4 + 4 + 9 + 0 + 9 + 0 = 26
Finally, we can plug in these values into the formula for the standard deviation:
s = sqrt [ Σ(x - X)2 / (n - 1) ] = sqrt [ 26 / (6 - 1) ] ≈ 1.83
Therefore, the standard deviation of this sample of counts is approximately 1.83.

How to Calculate the Probability?To calculate the probability that the frog will be on lily pad B after an hour, we can start by calculating the long-run distribution or steady-state probabilities of the frog's movement between the two lily pads.
Let p represent the probability that the frog is on lily pad B at any given time. We may develop two equations based on the probabilities given in the problem:
p = 0.85(1-p) (the frog moves from point A to point B with a probability of 0.85 and stays on point B with a probability of 1-p).
1-p = 0.65p (the frog moves from B to A with the probability of 0.65 and stays on A with the probability of 1-p).

proveAssume ={,,}⊂ℝ over ℝ with regular operations.The vectors , , and are distinct and none of them is the zerovector(c) Assume that A is linearly dependent. We define u = 2u, v, = -3u +4v, and w1 = u + 2v – tw for some t E R. Then, there exists t € R such that {U1, V1, w;} is linearly independent
{u, v, w} is linearly independent, and the statement is proved.
What is linear function?
A linear function is a mathematical function of the form f(x) = mx + b, where m and b are constants.
To prove this statement, we will use a proof by contradiction.
Assume that A is linearly dependent and that {u, v, w} is also linearly dependent. This means that there exist scalars α, β, and γ, not all zero, such that αu + βv + γw = 0.
Now, we will express w in terms of u and v:
w = u + 2v - tw1
Substituting w in the above equation, we get:
αu + βv + γ(u + 2v - tw) = 0
Simplifying this equation, we get:
(α + γ)u + (β + 2γ)v - γtw = 0
Since u, v, and w are distinct and none of them is the zerovector, α + γ ≠ 0 or β + 2γ ≠ 0 or -γt ≠ 0.
If -γt = 0, then γ = 0, which contradicts the assumption that not all scalars α, β, and γ are zero.
If -γt ≠ 0, then we can express t as t = γ' / (-γ) for some non-zero scalar γ'. Substituting t in the above equation, we get:
(α + γ)u + (β + 2γ)v + γ'w = 0
We can now express w in terms of u and v using the equation w = u + 2v - tw1, which gives:
(α + γ)u + (β + 2γ)v + γ'(u + 2v - tw) = 0
Simplifying this equation, we get:
(α + γ + γ')u + (β + 2γ + 2γ')v - γ'tw1 = 0
Since u, v, and w are distinct and none of them is the zerovector, it follows that the coefficients of u, v, and w1 are not all zero. Therefore, {u1, v1, w1} is linearly independent.
This contradicts the assumption that {u, v, w} is linearly dependent. Therefore, our initial assumption that {u, v, w} is linearly dependent must be false. Hence, {u, v, w} is linearly independent, and the statement is proved.

a. the period of a pendulum that is 8 cm long
b.the length of a pendulum that has a period of one second.
A pendulum that is approximately 24.75 cm long will have a period of one second.
We have,
We can use the formula T = k x √(L), where T is the period of the pendulum, L is the length of the pendulum, and k is a constant of proportionality.
To find k, we can use the information given for the pendulum with a length of 12 cm and a period of 0.7 seconds:
0.7 = k x √(12)
Solving for k:
k = 0.7 / √(12) ≈ 0.202
a.
Now we can use this value of k to find the period of a pendulum that is 8 cm long:
T = k x √(L) = 0.202 x √(8) ≈ 0.568 seconds
b.
To find the length of a pendulum that has a period of one second, we can rearrange the formula to solve for L:
T = k x √(L)
√(L) = T / k
L = (T / k)²
Plugging in T = 1 and k = 0.202, we get:
L = (1 / 0.202)² ≈ 24.75 cm

Given that the function:
[tex]f(x)=x^3+8x^2+x-42[/tex]
The function has zeros located at -7, 2, -3
First, let check f(2) = 0
[tex]2^3+8(2)+2-42=0[/tex]
[tex]8+16+2-42=0[/tex]
[tex]42-42=0[/tex]
Therefore, f(2) has a zero, that is (x - 2) is a factor of the polynomial function..
So, divide the given function by (x-2) to get the quadratic function.
[tex]\dfrac{x^3+8x^2+x-42}{x-2} =x^2+10x+21[/tex]
Now, solve the quadratic function.

[tex]x(x+7)+3(x+7)=0[/tex]
[tex]x+7=0 \ \text{and} \ x+3=0[/tex]
[tex]x=-7 \ \text{or} -3[/tex]
From the explanation above, it shows that -7, 2, and -3 are the roots (zeros) of the given polynomial function.
Thus, the behavior of the function can be described by using the degree and the leading coefficient.
The leading degree is 3 and the leading coefficient is 1.
So since the leading degree is odd (3), the end of the function will point in the opposite direction.
And since the leading coefficient is positive (+1), the graph rises to the right.
Hence, the behavior of the function falls to the left and rises to the right.

Find the value of each missing variable.
Check the picture below.
it consists of a quarter circle and two line segments, and repsersntets the velocity of an object during the six second interval. the object's average speed udirng the six second interval is
The quarter circle represents a distance of one-fourth of the circumference of a circle with a radius equal to the velocity of the object. Since the time interval is six seconds, the angular displacement of the quarter circle is (1/4) x 2π = π/2 radians. Therefore, the distance traveled along the quarter circle is [(π/2) x velocity + a + b]/6
To calculate the object's average speed during the six-second interval, we will first determine the distance traveled in each segment and then divide the total distance by the total time. In this case, the object moves in three parts: a quarter circle and two line segments.
Step 1: Determine the radius of the quarter circle using the given information (such as velocity or distance). To find the average speed of the object during the six-second interval represented by the quarter circle and two line segments, we need to first calculate the total distance traveled by the object.
Step 2: Calculate the circumference of the entire circle by using the formula C = 2πr, where C is the circumference and r is the radius.
Step 3: Find the length of the quarter circle by dividing the circumference by 4, as a quarter circle represents one-fourth of the entire circle.
Step 4: Determine the lengths of the two line segments using the given information.
Step 5: Add the length of the quarter circle and the lengths of the two line segments to find the total distance traveled.
Step 6: Divide the total distance traveled by the total time of six seconds to find the object's average speed during the six-second interval.
The two line segments represent the remaining distance traveled by the object. Let's assume the lengths of the two line segments are a and b, respectively. Then, the total distance traveled by the object is (π/2) x velocity + a + b.
Now, we can calculate the average speed of the object as the total distance traveled divided by the time interval of six seconds:
Average speed = (Total distance traveled) / (Total time)

You are encouraged to use MATLAB to automate the calculations on this problem, but it is not required. Please include all code with your solution if you do. Consider a random variable X with a ternary alphabet with symbols {A,B,C} with probabilities {0.60,0.6(1 – 0), 0.4}, where 0 is a modeling parameter. a) (15 Points) Assuming a uniform prior on 0, what is the arithmetic codeword for the sequence X4 = AACB? b) (15 Points) Suppose we assume a Beta(a,b) prior where a = 1 and ß = 5. How does the arithmetic code developed in (a) change?
We can then use the same arithmetic coding process as in part (a) to find the codeword for X4 = AACB with the updated probabilities. The final interval is [0.56, 0.6168) with a range of
a) Assuming a uniform prior on 0, we can use arithmetic coding to find the codeword for the sequence X4 = AACB.
First, we need to calculate the cumulative probabilities for each symbol:
P(A) = 0.60
P(B) = 0.6(1 - 0) = 0.24
P(C) = 0.4
Next, we set up the initial interval [0, 1) and divide it into sub-intervals proportional to the cumulative probabilities of the symbols:
Interval for A: [0, 0.60)
Interval for B: [0.60, 0.84)
Interval for C: [0.84, 1)
We then encode the sequence X4 = AACB by updating the interval based on the sub-intervals corresponding to each symbol:
Step 1: Interval for A = [0, 0.60), range = 0.60
Step 2: Interval for A = [0, 0.60 x 0.60) = [0, 0.36), range = 0.36
Step 3: Interval for C = [0.84, 1), range = 0.16
Step 4: Interval for B = [0.60, 0.60 + 0.24 x 0.16) = [0.60, 0.6448), range = 0.0448
The final interval is [0.60, 0.6448) with a range of 0.0448. To convert this to a binary codeword, we can use the following steps:
Multiply the interval by 2 and check if the integer part is 1 or 0.
If the integer part is 1, output a 1 and subtract 1/2 from the interval.
If the integer part is 0, output a 0 and keep the interval as is.
Repeat steps 1-3 until the desired precision is reached.
For example, multiplying the interval [0.60, 0.6448) by 2 gives [1.20, 1.2896). Since the integer part is 1, we output a 1 and subtract 1/2 to get the new interval [0.20, 0.2896). Multiplying this by 2 gives [0.40, 0.5792), and since the integer part is 0, we output a 0 and keep the interval as is. Finally, multiplying by 2 gives [0.80, 1.1584), and since the integer part is 1, we output a 1 to get the binary codeword:
Arithmetic codeword for X4 = AACB: 101
b) If we assume a Beta(a,b) prior where a = 1 and b = 5, we need to update the probabilities of the symbols to reflect the prior information. The updated probabilities are:
P(A) = (0.60 + a - 1) / (2 + a + b) = 0.56
P(B) = (0.24 + a - 1) / (2 + a + b) = 0.08
P(C) = (0.40 + a - 1) / (2 + a + b) = 0.36
We can then use the same arithmetic coding process as in part (a) to find the codeword for X4 = AACB with the updated probabilities. The final interval is [0.56, 0.6168) with a range of

Let (M,d) be a discrete metric space. Give explicitly a simplified expression for the following (a) Si = B(a, j), S2 = B(a,g), S3 = B(a, 1) (b) Ti = S(0,7), T2 = S(a. 1)], T3 = S(a, 1)
T3 = S(a, 1) = {x ∈ M : d(x,a) < 1} = {a} U (M{a}), using the same argument as for S3 in part (a).
In a discrete metric space, any subset of the space is an open set, since every point has a neighborhood of radius 1 that contains only that point. Therefore, for any point a in the discrete metric space, we have:
(a) Si = B(a, j) = {x ∈ M : d(x,a) < j} = {a}, since the only point within a distance of j from a is a itself.
S2 = B(a, g) = {x ∈ M : d(x,a) < g} = {a}, since the only point within a distance of g from a is a itself.
S3 = B(a, 1) = {x ∈ M : d(x,a) < 1} = {a} U (M{a}), since every point in M except a is within a distance of 1 from a, so the open ball of radius 1 centered at a contains all points in M except a, as well as a itself.
(b) Ti = S(0,7) = {x ∈ M : d(x,0) < 7} = M, since every point in the discrete metric space is within a distance of 7 from 0.
T2 = S(a, 1) = {x ∈ M : d(x,a) < 1} = {a} U (M{a}), using the same argument as for S3 in part (a).
T3 = S(a, 1) = {x ∈ M : d(x,a) < 1} = {a} U (M{a}), using the same argument as for S3 in part (a).

a rope is stretched from the top of a 6-foot-high wall, which we use to determine the vertical axis. the end of the rope is attached to the ground at a point 24 horizontal feet away at a point on the positive horizontal axis. what is the slope of the line representing the rope? (suggestion: be careful about the sign.)
The slope of the line representing the rope is -1/4.
To find the slope of the line representing the rope, we need to use the formula for slope, which is:
slope = rise / run
In this case, the rise is the height of the wall, which is 6 feet, and the run is the horizontal distance between the wall and the point where the rope is attached to the ground, which is 24 feet. However, we need to be careful about the sign of the slope, since the rope is going down from the wall to the ground.
To take this into account, we can use the convention that a positive slope means a line is going up from left to right, and a negative slope means a line is going down from left to right. In this case, since the rope is going down, we know the slope will be negative.
So, we can calculate the slope as follows:
slope = - rise / run
slope = - 6 / 24
slope = - 1/4
Therefore, the line representing the rope has a slope of -1/4.

134 1/2
Therefore, the area of the trapezoid is 1338 3/4 square units.
A quadrilateral with at least one set of parallel sides is known in geometry as a trapezium, or trapezium in British and other versions of English. In Euclidean geometry, a trapezium is invariably a convex quadrilateral. The trapezoid's parallel sides are referred to as its bases.
To find the area of a trapezoid, we use the formula:
Area = (1/2) × (sum of parallel sides) × (height)
In this case, we have the following information:
The two parallel sides are 12 1/4 and 24 1/4.
The height is 73 1/2.
First, we need to add the two parallel sides to find the sum:
12 1/4 + 24 1/4 = 36 1/2
Next, we can plug these values into the formula:
Area = (1/2) × 36 1/2 × 73 1/2
Area = 1338.75
