Answer: 210 mm²
Step-by-step explanation:
A = 1/2(long base + short base) x height
A = 1/2(18 + 10)(15)
A = 1/2(28)(15)
A = 210 mm²
A line segment drawn between points B and C on a circle forms its diameter. Point A is taken arbitrarily on the circumference of the circle, and line segments are drawn from A to B and A to C. Classify ∠BAC.(1 point)
acute angle
obtuse angle
straight angle
right angle
Answer:
Option D
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.

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.

(b) Show that cov(ra, rt) = 10²e-(s+t) (e²s 1). Deduce that var(r) = 10²(1-e-2¹).
9. The Vasicek term structure model for the short interest rate, r₁, follows the stochastic differential equation dre (ar)dt+odB, where a and are constants and B, is a standard Brownian motion.
In the Vasicek term structure model, the covariance between ra and rt is given by cov(ra, rt) = 10²e-(s+t) (e²s 1). From this, we can deduce that the variance of r is var(r) = 10²(1-e-2¹).
In the Vasicek term structure model, the short interest rate, r₁, follows the stochastic differential equation:
dr₁ = a(b - r₁)dt + σdW
where a and b are constants, σ is the volatility parameter, and dW is a standard Brownian motion.
To find the covariance between rₐ and rₜ, we use the covariance formula for the stochastic differentials equation:
cov(dr₁, drₜ) = cov(a(b - r₁)dt + σdW, a(b - rₜ)dt + σdW)
Since the covariance between the Brownian motion terms is zero, we only need to consider the covariance between the drift terms:
cov(a(b - r₁)dt, a(b - rₜ)dt) = a²(b - r₁)(b - rₜ)dt²
Integrating this expression over the time interval [0, s+t], we obtain:
cov(ra, rt) = a²(b - ra)(b - rt)∫[0,s+t] dt = a²(b - ra)(b - rt)(s + t)
Given cov(ra, rt) = 10²e-(s+t) (e²s - 1), we can equate the expressions and solve for a²(b - ra)(b - rt):
10²e-(s+t) (e²s - 1) = a²(b - ra)(b - rt)(s + t)
Simplifying the equation, we have:
(b - ra)(b - rt) = 10²e-(s+t) (e²s - 1)/(a²(s + t))
From this equation, we can see that the covariance depends on the values of b, ra, rt, s, t, and a.
To deduce the variance of r, we set t = s in the above equation:
(b - ra)(b - ra) = 10²e-2s (e²s - 1)/(a²(2s))
Simplifying further, we obtain:
var(r) = (b - ra)² = 10²(1 - e-2s)/a²
Hence, the variance of r is given by var(r) = 10²(1 - e-2s)/a².

after preparing a horizontal analysis of Blanchet
corporations balance sheet for 2019, what are some observations you
can make?
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.

A fcompany has a constant 306200 shares during the fiscal year. At the beginning of the year it has an equity of $4699902 in their balance sheet, and during the year, as indicated by the income statement, it has a net income $399786 and pays out $297789 in dividends. What will be its book value per share at the end of the fiscal year? Answer to two places.
The book value per share at the end of the fiscal year will be approximately $15.35.
To calculate the book value per share, we need to divide the equity at the end of the fiscal year by the number of shares outstanding. Let's break down the calculation:
The number of shares outstanding: The company has a constant 306,200 shares during the fiscal year.
Equity at the beginning of the year: The balance sheet shows an equity of $4,699,902 at the beginning of the year.
Net income: The income statement indicates a net income of $399,786.
Dividends paid: The company pays out $297,789 in dividends.
To find the equity at the end of the fiscal year, we need to add the net income and subtract the dividends paid from the equity at the beginning of the year:
Equity at the end of the fiscal year = Equity at the beginning of the year + Net income - Dividends paid
= $4,699,902 + $399,786 - $297,789
= $4,801,899
Finally, to calculate the book value per share, we divide the equity at the end of the fiscal year by the number of shares outstanding:
Book value per share = Equity at the end of the fiscal year / Number of shares outstanding
= $4,801,899 / 306,200
≈ $15.65 (rounded to two decimal places)
Therefore, the book value per share at the end of the fiscal year will be approximately $15.35.

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

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

To find the compositions f∘f, g∘g, f∘g, and g∘f, we substitute the function expressions into the compositions:
1. f∘f:
(f∘f)(n) = f(f(n))
= f(2n+1)
= 2(2n+1) + 1
= 4n + 2 + 1
= 4n + 3
So, (f∘f)(n) = 4n + 3.
2. g∘g:
(g∘g)(n) = g(g(n))
= g(3n-1)
= 3(3n-1) - 1
= 9n - 3 - 1
= 9n - 4
So, (g∘g)(n) = 9n - 4.
3. f∘g:
(f∘g)(n) = f(g(n))
= f(3n-1)
= 2(3n-1) + 1
= 6n - 2 + 1
= 6n - 1
So, (f∘g)(n) = 6n - 1.
4. g∘f:
(g∘f)(n) = g(f(n))
= g(2n+1)
= 3(2n+1) - 1

So, (g∘f)(n) = 6n + 2.

Find the optimum solution and draw the graph
Maximise Z= x + y, subject to x - y S-1, -x + y = 0, x,
The optimum solution for the maximization problem is Z = 0 at the point (0, 0). The graph of the feasible region consists of the line y = x and the shaded region above the line y = x - 1.
To compute the optimum solution and draw the graph for the maximization problem:
Maximize Z = x + y
Subject to the constraints:
x - y ≤ 1
-x + y = 0
x, y ≥ 0
First, let's plot the feasible region by graphing the constraints on a coordinate plane.
For the constraint x - y ≤ 1, we can rewrite it as y ≥ x - 1. This represents a boundary line with a slope of 1 and a y-intercept of -1. Shade the region above this line to satisfy the constraint.
For the constraint -x + y = 0, rewrite it as y = x. This represents a line passing through the origin with a slope of 1. Plot this line.
Next, plot the x and y axes and shade the feasible region that satisfies both constraints.
To compute the optimum solution, we need to evaluate the objective function Z = x + y at the corner points (vertices) of the feasible region.
The corner points can be identified by the intersection of the lines and the feasible region boundaries. In this case, there is only one corner point, which is the intersection of the lines y = x and y = x - 1. Solving these equations simultaneously gives x = 0 and y = 0.
Thus, the optimum solution occurs at the corner point (0, 0), where Z = 0 + 0 = 0.
Therefore, the optimum solution is Z = 0 at the point (0, 0).
