Determine at which points f(z) = Reſiz) is differentiable by using the limit definition of the derivative
Main answer: f(z) = Reſiz is differentiable at every point of the complex plane where partial derivative with respect to x exists and the Cauchy-Riemann equations are satisfied.
Supporting answer: Given f(z) = ReſizLet z = x + iy∴ f(z) = Re(x + iy)z = x - iyi.e. x = ½ (z + z¯)and y = -½i(z - z¯)Hence f(z) = ½ (z + z¯ ) Differentiating f(z) partially with respect to x, we get,fx = ∂(x + y)/∂x = 1And differentiating f(z) partially with respect to y, we get,fy = ∂(x + y)/∂y = 1Now, for f(z) to be differentiable, it is necessary thatfx = uxx + ivxxandfy = uyx + ivyxwhere u = Re (f(z)) and v = Im(f(z))i.e. uxx = vyyanduyx = -vxy These equations are known as the Cauchy-Riemann equations. On substituting, we get uxx = vyy∴ 1 = 0which is not true. Hence f(z) is not differentiable when partial derivative with respect to y exists. So f(z) is differentiable at every point of the complex plane where partial derivative with respect to x exists and the Cauchy-Riemann equations are satisfied.

3) The coordinates of the point 2/3 of the way from A to B are (3, -1).
1) The component form of AB is (-3-0, 5-2) or (-3, 3).
2) AB = (-3, 3).
3) To determine the coordinates of the point 2/3 of the way from A to B, we can use the formula for finding a point on a line segment. Let's call the point we're looking for C. The x-coordinate of C can be found by taking 2/3 of the difference between the x-coordinates of A and B and adding it to the x-coordinate of A. Similarly, the y-coordinate of C can be found by taking 2/3 of the difference between the y-coordinates of A and B and adding it to the y-coordinate of A.
Using this formula, we can calculate the x-coordinate of C as:
x-coordinate of C = (2/3)*(2 - 5) + 5 = (2/3)*(-3) + 5 = -2 + 5 = 3.
And the y-coordinate of C as:
y-coordinate of C = (2/3)*(0 - (-3)) + (-3) = (2/3)*(3) - 3 = 2 - 3 = -1.
Therefore, the coordinates of the point 2/3 of the way from A to B are (3, -1).

find the length of the arc on a circle of radius 14 inches intercepted by a central angle 140.
The length of the arc intercepted by a central angle of 140° on a circle with a radius of 14 inches is approximately 34.1557 inches.
To find the length of the arc intercepted by a central angle on a circle, we can use the formula:
Arc Length = (Central Angle / 360°) * Circumference
In this case, the radius of the circle is 14 inches, and the central angle is 140°.
First, we need to calculate the circumference of the circle:
Circumference = 2 * π * radius
Circumference = 2 * π * 14 inches
Now, we can calculate the length of the arc:
Arc Length = (140° / 360°) * Circumference
Arc Length = (140/360) * (2 * π * 14 inches)
Arc Length ≈ (0.3889) * (2 * 3.1416 * 14 inches)
Arc Length ≈ 0.3889 * 87.9648 inches
Arc Length ≈ 34.1557 inches
Therefore, the length of the arc intercepted by a central angle of 140° on a circle with a radius of 14 inches is approximately 34.1557 inches.

B) 8 to 12 years of experience
C) $10,000 to $90,000 annual salary
D) $40,000 to $60,000 annual salary
Answer: 8 to 12 years
Step-by-step explanation: A cluster is formed when several data points lie in a small interval. The domain of the cluster is the set of x-coordinates.
The range of the cluster in the scatter plot is between $40,000 and $60,000 when the data points are heavily clustered between the years 8 to 12.
What is scatter plot?Scatter plots are used to observe and plot relationships between two numeric variables graphically with the help of dots. The dots in a scatter plot shows the values of individual data points.
Given that, on scatter plot
Years of experience is represented at x-axis
Annual Salary is represented at y-axis
From the scatter plot, it is clear that from the x-axis the data points are tightly clustered between the years 8 to 12. As major portion of the data points lie between 8 to 12 years.
Similarly, from the y-axis the data points are tightly clustered between between $40,000 and $60,000. As major portion of the data points lie between $40,000 and $60,000.
When the certain data points in a scatter plot make distinct groups, these groups are considered as clusters. Those data points normally appear to be converged around a particular value.
Therefore, the range of the cluster in the scatter plot is between $40,000 and $60,000 for the data points between the years 8 to 12.

P and Q are on thesurface.
P is on the surface, butQ is not.
Q is on the surface, butP is not.
Neither P or Q are onthe surface.
P(4, 2, 6) is on the given surface, but Q(5, 1, -11) is not. The correct answer is that P is on the surface, but Q is not
To determine whether the points P(4, 2, 6) and Q(5, 1, -11) lie on the given surface, we need to check if their coordinates satisfy the equation r(u, v) = <u + v, u^2 - v, u + v^2>.
For P(4, 2, 6):
Plugging in the coordinates of P into the equation, we have:
r(4, 2) = <4 + 2, 4^2 - 2, 4 + 2^2> = <6, 14, 8>.
The coordinates of P(4, 2, 6) match the coordinates obtained from the equation, so P lies on the surface.
For Q(5, 1, -11):
Plugging in the coordinates of Q into the equation, we have:
r(5, 1) = <5 + 1, 5^2 - 1, 5 + 1^2> = <6, 24, 6>.
The coordinates of Q(5, 1, -11) do not match the coordinates obtained from the equation, so Q does not lie on the surface.
Therefore, the correct answer is that P is on the surface, but Q is not. The given coordinates for P(4, 2, 6) satisfy the equation, while the coordinates for Q(5, 1, -11) do not match the equation, indicating that Q does not lie on the given surface.

question 9 of 10 explain how you can determine the sign of the sum of two integers if one integer is positive and the other integer is negative.
To determine the sign of the sum of two integers when one integer is positive and the other is negative, we can follow a simple rule based on their magnitudes.
If the magnitude of the positive integer is greater than the magnitude of the negative integer, the sum will be positive. This is because the positive integer outweighs the negative integer, resulting in a positive value.
On the other hand, if the magnitude of the negative integer is greater than the magnitude of the positive integer, the sum will be negative. In this case, the negative integer dominates and determines the sign of the sum.
In both scenarios, the sign of the larger magnitude integer takes precedence and determines the sign of the sum. It is important to note that the sum will always have the sign of the integer with the larger magnitude, regardless of the specific values of the integers involved.
By considering the magnitudes of the integers, we can easily determine the sign of their sum when one integer is positive and the other is negative.

In a recent election 65% of people supported reelecting the incumbent. Suppose a poll is done of 1390 people. If we used the normal as an approximation to the binomial, what would the mean and standard deviation be?
A standard deviation of 23.16.
In a recent election, where 65% of people supported reelecting the incumbent, a poll was conducted with a sample size of 1390 people.
To approximate the binomial distribution with a normal distribution, we can calculate the mean and standard deviation.
The mean is determined by multiplying the sample size (1390) by the proportion of support (0.65), resulting in a mean of 898.5.
The standard deviation is calculated by taking the square root of the product of the proportion of support (0.65) with the proportion of opposition (0.35), divided by the sample size, and then multiplied by the square root of the sample size.
This yields a standard deviation of approximately 23.16.

Which of the following would indicate the possible presence of multicollinearity in a regression analysis?
a. a significant p-value for a test of overall significance
b. a high correlation between two or more independent variables.
c. a small value for the coefficient of determination
d. All of these choices would be indicators of possible multicollinearity.
B) A high correlation between two or more independent variables would indicate the possible presence of multicollinearity in a regression analysis.
Multicollinearity occurs when two or more independent variables in a regression model have a strong correlation with one another, making it difficult to distinguish the individual influence of each independent variable on the dependent variable.
Poorly constructed experiments, heavily observational data, introducing new variables that are dependent on other factors, including identical variables in the dataset, incorrect use of dummy variables, or inadequate data can all lead to multicollinearity.
Calculating the variance inflation factor (VIF) for each independent variable is one way for detecting multicollinearity; a VIF value more than 1.5 shows multicollinearity.
To correct multicollinearity, one of the highly correlated variables can be removed, combined into a single variable, or a dimensionality reduction approach such as principal component analysis can be used.

What is the p-value? (Round your answer to four decimal places.)
p-value =
The p- value is approxiamately 0.0001.
To calculate the test statistic, we first need to find the standard error of the difference between the two sample proportions. The formula for the standard error is SE = √(( p1 ×( 1- p1)/ n1)( p2 ×( 1- p2)/ n2)) Substituting the given values into the formula,
we get SE = √((0.25 ×( 1-0.25)/ 200)(0.13 ×( 1-0.13)/ 300)) =0.0326. The test statistic is also calculated as the difference between the sample proportions divided by the standard error.
Test Statistic = ( p1- p2)/ SE = (0.25-0.13)/0.0326 =3.68.
To find the p- value, we compare the test statistic to the applicable distribution. Since the indispensable thesis is one- tagged( p1- p2> 0), we'd use the standard normal distribution. Looking up the test statistic of3.68 in the standard normal distribution table, we find that the corresponding p- value is veritably close to 0.0001.
This means that if the null thesis( H0 p1- p2 ≤ 0) is true, there's a veritably low probability(0.0001) of observing a test statistic as extreme as the one calculated from the sample data. Hence, we've strong substantiation to reject the null thesis in favor of the indispensable thesis( Ha p1- p2> 0).
