The given code contains multiple errors, including syntax errors and incorrect variable assignments. Consequently, it would not produce the intended output.

The intended code is meant to solve a system of equations. However, it contains errors that hinder its functionality. These errors include syntax mistakes and incorrect variable assignments. Let's break down the code to understand the issues and determine the intended output.

In the first part of the code, the matrix A is incorrectly defined. The commas are placed before the plus sign, resulting in a syntax error. Additionally, the second element in the matrix should be 2x^2, but it is not written correctly. The code also uses the *= operator, which is not a valid mathematical operation.

Moving on to the second equation, the matrix b is defined correctly. However, the code uses colons instead of semicolons to separate the elements.

Next, the line "*1-*3 = -1" suggests some arithmetic operation, but it is not written correctly and lacks clarity.

Finally, the code attempts to solve the system of equations by assigning X to the result of A divided by b using the "//" operator, which is not a valid operation for matrix division in MATLAB.

Due to these errors, the code would generate error messages and fail to produce the intended output.

To calculate the increase in net worth from the savings, we need to find 4.5% of the total income earned.

Total income earned = $65,000

To determine the increase in net worth from savings, we calculate 4.5% of the total income. Multiplying $65,000 by 4.5% gives us $2,925.

Savings = 4.5% of $65,000

[tex]=0.045*$65,000\\=$2,925[/tex]

This represents the amount saved by the investor over the course of one year. Therefore, the investor's net worth would have increased by $2,925. This amount reflects the portion of income saved and not spent, contributing to the overall growth of the investor's financial position.

Therefore, the investor would have increased her net worth by $2,925 in one year.

The correct answer is A. $2,925.

The series converges for -8 < x < -4, and the radius of convergence is 2.

To find the radius of convergence and interval of convergence of the series, we'll use the ratio test.

The series given is:

Σ (n=1 to ∞) [tex]2^{(-n)}(x + 6)^n[/tex]

We'll apply the ratio test to determine the convergence behavior:

lim(n→∞) |(a_{(n+1)})/(a_n)|

= lim(n→∞) |[tex][2^{(-(n+1)})(x + 6)^{(n+1)}] / [2^{(-n)}(x + 6)^n][/tex]|

= lim(n→∞) |[tex][2^{(-(n+1)})(x + 6)] / [2^{(-n)}][/tex]|

= lim(n→∞) |(x + 6)/2|

To ensure convergence, we need the above limit to be less than 1:

|(x + 6)/2| < 1

Now, let's consider the cases when the above inequality holds true:

Case 1: (x + 6)/2 < 1

Simplifying, we get:

x + 6 < 2

x < -4

Case 2: -(x + 6)/2 < 1

Simplifying, we get:

x + 6 > -2

x > -8

Combining the results from both cases, we have:

-8 < x < -4

Therefore, the interval of convergence is -8 < x < -4.

To find the radius of convergence, we consider the endpoints of the interval of convergence (-8 and -4). The radius of convergence (R) is half the length of the interval of convergence.

R = (|-8 - (-4)|)/2

  = 4/2

  = 2

Hence, the radius of convergence is 2.

In summary, the series converges for -8 < x < -4, and the radius of convergence is 2.

Overall, the horizontal analysis of Blanchet Corporation's balance sheet for 2019 suggests positive growth and financial stability.

There has been a significant increase in total assets from the previous year. This indicates potential growth and expansion in the company's operations.

The liabilities have also increased, but not at the same rate as the assets. This suggests that the company may have taken on additional debt or financing to support its growth.

The retained earnings have shown a positive trend, indicating that the company has been profitable and able to retain a portion of its earnings for reinvestment or future use.

The equity section has also grown, which can be attributed to the increase in retained earnings and potentially additional capital investments.

The increase in assets and retained earnings indicates the company's ability to generate profits and reinvest in its operations. However, the increase in liabilities should be carefully monitored to ensure it is manageable and sustainable in the long term.

Answer : The value of the missing term is (1+0.2147)^6≈ 150.

Explanation :

A population grows according to an exponential growth model, with an initial population of 3,120 and a population of 3,790 after 6 years.

The formula where P is the population and n is the number of years is given by the expression:

P = 3120*(1+r)^n  where r is the growth rate and n is the number of years.                                                                                     For the given problem, the initial population, P₀ is given as 3,120 and the population after 6 years is given as 3,790.               So, the population increased by 3,790 - 3,120 = 670 people in 6 years.                                                                                                     Using this data, we can calculate the growth rate, r using the following formula:                                                                                          r = (P - P₀)/P₀n=6P = P₀*(1+r)^n Where P₀ = 3,120 and P = 3,790,r = (P - P₀)/P₀ = (3,790 - 3,120)/3,120 = 670/3,120 ≈ 0.2147 P = 3,120*(1+0.2147)^6 ≈ 150 * 3,120

Therefore, the value of the missing term is (1+0.2147)^6 ≈ 150.

The given problem can be written in the following form: minimize f(x)= 22 - (21 - 2)3 + 3 subject to g(x) = x2 > 1.The extremizer point is the point that satisfies the conditions that have been given in the question. Therefore, the extremizer point in this problem is x=(1,1].In order to find the extremizer point of a problem, we need to calculate the derivative of the objective function and then equate it to zero to find the point where it attains its minimum value. Here, however, we have only one point to choose from that satisfies the given constraint, so it is the extremizer point.

A point in a convex set that does not lie on any open line segment connecting two points in the set is referred to as an extreme point in mathematics.

A right angle

Step-by-step explanation:

in circle geometry, we have several theorems that govern angles formed by chords drawn in circles.

One of the theorems states that the angle subtended on the circumference of a circle by a chord which is drawn across the center of the circle (which is the diameter) equals 90 degrees. This means that it is a right-angle.

Analytically, we can also sketch out the problem and see that we can divide the shape formed by points BAC into an isosceles triangle. (The two radii forming the sides while the diameter forms the base).  We can also run a bisector of the isosceles triangle through point A to meet the diameter. We can see that it forms two 45 by 45 degree right-angled triangles. Thus proving that angle BAC is indeed a right angle.

Step-by-step explanation:

a)The standard error of the mean is 0.85.b) the margin of error is 1.67 at 95% confidence level.

a) To calculate the standard error of the mean, the formula is given by:σx = σ / √nWhere,σ is the population standard deviation, n is the sample size√n = √50 = 7.071σx = σ / √n= 6 / 7.071σx = 0.85 (rounded to two decimal places)

b) At 95% confidence level, the margin of error is calculated by using the following formula:

ME = z* σxWhere,z* is the z-value for 95% confidence level and σx is the standard error of the mean.

The z-value for 95% confidence level is 1.96

ME = z* σx = 1.96 x 0.85

ME = 1.67 (rounded to two decimal places)

Therefore, the margin of error is 1.67 at 95% confidence level.
