Answer:

35

Step-by-step explanation:

- when rounding to the nearest whole number, look at the number after the decimal point, if it is 5 or higher, add 1 to the number before the decimal (in this case, 34 will be 35), if its 4 or lower, keep the number as it is.

After rounding, neglect the numbers after the decimal.

34.75 = 35.00 = 35

The analyst should use the alpha aesthetic. The alpha aesthetic makes some points on a plot more transparent than others to call out specific data points.

A set of points plotted on a horizontal and vertical axis is known as a scatter plot. Because they can demonstrate the degree of correlation, if any, between the values of observed quantities or phenomena, scatter plots are crucial in statistics (called variables). In an effort to demonstrate the degree to which one variable is influenced by another, scatter plots are used to plot data points on a horizontal and vertical axis. The values of the columns set on the X and Y axes determine the position of the marker that represents each row in the data table.

Answer:

\(\cos(\theta) + \sin(\theta)\)

Step-by-step explanation:

Use the sine angle sum identity.

\(\sin(a+b)=\sin(a)\cos(b)+\cos(a)\sin(b)\)

\(\sin(45\textdegree + \theta)=\sin(45\textdegree)\cos(\theta)+\cos(45\textdegree)\sin(\theta)\)

Now, simplify \(\sin(45\textdegree)\) and \(\cos(45\textdegree)\) to \(\dfrac{\sqrt2}{2}\):

\(\sin(45\textdegree + \theta)=\dfrac{\sqrt2}{2} \cdot \cos(\theta)+\dfrac{\sqrt2}{2} \cdot \sin(\theta)\)

Then, factor out \(\dfrac{\sqrt2}{2}\) from each term.

\(\sin(45\textdegree + \theta)=\dfrac{\sqrt2}{2} \cdot ( \cos(\theta)+\sin(\theta))\)

Finally, identify what is in the parentheses corresponding to the blank space in the question.

\(\cos(\theta) + \sin(\theta)\)

The values of r fulfil the differential equation 5y" + 14y' 3y = 0 for the function y = e^rx are 0.123 and -2.523.

As per the question given,  

We have y = e^(rx), so y' = re^(rx) and y'' = r^2e^(rx). Substituting these expressions into the differential equation, we get:

5(r^2e^(rx)) + 14(re^(rx)) - 3(e^(rx)) = 0

Simplifying, we get:

e^(rx)(5r^2 + 14r - 3) = 0

For y = e^(rx) to satisfy the differential equation, the expression in parentheses must equal zero:

5r^2 + 14r - 3 = 0

Using the quadratic formula, we find:

r = (-14 ± sqrt(14^2 - 4(5)(-3))) / (2(5)) = (-14 ± sqrt(244)) / 10

So the values of r that make the function y = e^(rx) satisfy the differential equation are:

r = (-14 + sqrt(244)) / 10 ≈ 0.123 or r = (-14 - sqrt(244)) / 10 ≈ -2.523

The largest integer that is a divisor of (n 1)(n 3)(n 57)(n 9 ) for all positive even integers $n$ is the largest prime factor of $n_9$.

The given expression consists of five consecutive odd numbers: $(n_1), (n_3), (n_5), (n_7), (n_9)$. When we multiply these consecutive odd numbers, all their prime factors cancel out except for the largest prime factor, which is the prime factor of the largest odd number.

Since we are considering even numbers, the largest odd number in this case is $n_9$. Therefore, the largest prime factor of the expression is the largest prime factor of $n_9$.

To find the largest prime factor of a number, we can start dividing it by the smallest prime numbers (2, 3, 5, etc.) and keep dividing until we can't divide anymore. The result will be the largest prime factor.

the optimal solution to maximize Z is x1 = 25 and x2 = 0, with Z = 3000.

To solve the given linear programming model graphically, we need to plot the feasible region and identify the corner points to find the optimal solution. Here's the step-by-step process:

1. Plot the constraints:

  - Plot the line x1 = 40 (vertical line at x1 = 40).

  - Plot the line x2 = 10 (horizontal line at x2 = 10).

  - Plot the line 20x1 + 10x2 = 500 (which can be rewritten as 2x1 + x2 = 50).

  - Shade the feasible region that satisfies all the constraints.

2. Identify the corner points:

  - Determine the coordinates of the corner points where the boundary lines intersect.

3. Evaluate the objective function:

  - Calculate the value of the objective function Z = 120x1 + 80x2 for each corner point.

4. Determine the optimal solution:

  - Select the corner point that maximizes the objective function Z.

Here's the graphical representation of the feasible region:

      |

 40   |           C

      |          /

      |         /

      |        /

      |     /    Feasible Region

 10   |_____/_________________

      0   10  20  30  40  50

            0`

The corner points of the feasible region are:

A: (0, 0)

B: (0, 10)

C: (25, 0)

D: (20, 5)

Now, we evaluate the objective function Z = 120x1 + 80x2 for each corner point:

Z(A) = 120(0) + 80(0) = 0

Z(B) = 120(0) + 80(10) = 800

Z(C) = 120(25) + 80(0) = 3000

Z(D) = 120(20) + 80(5) = 2400

From the above calculations, we can see that the maximum value of Z occurs at point C: (25, 0).

The inter-cluster distances using min, max, and group average distance metrics are 1, 2, and 2, respectively.

To find the inter-cluster distances using different distance metrics, we can calculate the distances between all pairs of points in the clusters and then apply the desired distance metric.

For the given clusters {1, 5} and {2, 3, 4}, let's calculate the inter-cluster distances using the following distance metrics:

Min distance: We calculate the distance between the closest pair of points from each cluster. In this case, the min distance between the clusters is between point 1 (from the first cluster) and point 2 (from the second cluster). Therefore, the min distance between the clusters is 1.

Max distance: We calculate the distance between the farthest pair of points from each cluster. In this case, the max distance between the clusters is between point 5 (from the first cluster) and point 4 (from the second cluster). Therefore, the max distance between the clusters is 2.

Group average distance: We calculate the average distance between all pairs of points from the two clusters. The distances between each pair of points are as follows:

1-2 = 1, 1-3 = 2, 1-4 = 3, 5-2 = 3, 5-3 = 4, 5-4 = 1.

Adding up these distances and dividing by the total number of pairs (6), we get an average distance of (1+2+3+3+4+1)/6 = 2.

In conclusion, the inter-cluster distances using min, max, and group average distance metrics are 1, 2, and 2, respectively.

Step-by-step explanation:

31.112 is actually greater than 30.678 because 31 is a greater number than 30. so the statement stated is false.

24.510 is greater than 24.5 because if you add 2 zeros to 24.5, it would be 24.500(adding zeros after decimal point doesnt change the value). 24.500 is less than 24.510. the numbers are not equal.

72.49 is greater than 72.469 because if you add a zero to 72.49, it will be 72.490. 72.490 is greater than 72.469.

Function transformation involves changing the position of a function

The new function is:\(\mathbf{h(x) = \frac 43 mx + b}\)

The function is given as:

\(\mathbf{y = mx +b}\)

The ratio of the slopes of both segments is given as:

\(\mathbf{Ratio = \frac 43}\)

Let the slope of the new segment be m2.

The slope of \(\mathbf{y = mx +b}\) is m.

So, we have:

\(\mathbf{m_2 : m = \frac 43}\)

Express as fractions

\(\mathbf{\frac{m_2 } m = \frac 43}\)

Multiply both sides by m

\(\mathbf{m_2 = \frac 43m}\)

From the list of given options,

\(\mathbf{h(x) = \frac 43 mx + b}\) has a slope of \(\mathbf{m_2 = \frac 43m}\)

Hence, the required function is:\(\mathbf{h(x) = \frac 43 mx + b}\)

2. 180-90-26 = 64

3. 180-90-60 =30

Answer:

Step-by-step explanation:

1)  tan45 = x/10  

x = 10(tan45) = 10

cos45 = 10/y    

y = 10/(cos45) = 14.14

2) cos26 = 8/x  

x = 8/cos26 = 8.9

3) sin60 = y/12

y = 12(sin60) = 10.4

cos60 = x/12

x = 12(cos60) = 6

4)  Draw a line from top of triangle straight down and perpendicular to the 15 leg, label it z.  This divides the 15 leg into 2 segments: y and (15-y).

cos89 = y/12

y = 12(cos89) = 0.21

sin89 = z/12

z = 12

15 - 0.21 = 14.79

Now you can solve for x:

x² = 14.79² + 12²

x = \(\sqrt{362.74}\) = 19

Step-by-step explanation:

We can start solving this equation by taking the logarithm of both sides of the equation, using any base we prefer. Let's use the natural logarithm, denoted by "ln":

ln(9^x) = ln((1/3)^(x+3))

Using the rule that ln(a^b) = b*ln(a) for any positive real number a and any real number b, we can simplify the left-hand side:

x*ln(9) = (x+3)*ln(1/3)

Next, we can simplify the right-hand side using the rule that ln(1/a) = -ln(a) for any positive real number a:

x*ln(9) = -(x+3)*ln(3)

Now we can solve for x by isolating it on one side of the equation. First, let's simplify the logarithmic terms using the fact that ln(9) = 2*ln(3):

2x*ln(3) = -(x+3)*ln(3)

Dividing both sides of the equation by ln(3), we get:

2x = -(x+3)

Simplifying and solving for x, we obtain:

2x = -x - 3

3x = -3

x = -1

Therefore, the solution to the equation 9^x = (1/3)^(x+3) is x = -1.
