Triangle in (22) have value of side z = 4, and angles x = 53°, y = 37°. The triangle in (23) have the value of it sides x = 35, z = 83, and an angle y = 65°. Using trigonometric ratios to the nearest whole numbers.
What is trigonometric ratios?The trigonometric ratios is concerned with the relationship of an angle of a right-angled triangle to ratios of two side lengths.
The basic trigonometric ratios includes;
sine, cosine and tangent.
(22). by Pythagoras rule;
z = √(5² - 3²) = 4
sin x = 4/5
x = sin⁻¹(4/5) {cross multiplication}
x = 53.1301
y = 180 - (53 + 90) {sum of interior angles of a triangle}
y = 37°
(23). cos 25 = 75/z {adjacent/hypotenuse}
z = 75/cos 25 {cross multiplication}
z = 82.7533
sin 25 = x/82.7533
x = 82.7533 × sin 25 {cross multiplication}
x = 34.9731
y = 180 - (25 + 90)
y = 65°
Therefore, the triangle in (22) have value of side z = 4, and angles x = 53°, y = 37°. The triangle in (23) have the value of it sides x = 35, z = 83, and an angle y = 65°. Using trigonometric ratios to the nearest whole numbers.

Step-by-step explanation:
samantha used craft wire to make the design shown. she first made the smaller quadrilateral. then she enlarged the smaller quadrilateral to make the larger quadrilateral, using a scale factor that extended the 6-centimeter side by 3 centimeters. what total length of craft wire did samantha use for both quadrilaterals?
The total length of craft wire used by Samantha is 10x + 9
What is the scale factor?
A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
Let's call the length of the smaller quadrilateral's 6-centimeter side "x".
Then the length of the corresponding side in the larger quadrilateral would be 6+3=9 centimeters, since the scale factor is 3.
To find the total length of craft wire used, we need to add up the lengths of all the sides in both quadrilaterals.
The smaller quadrilateral has four sides, each with a length of x.
The larger quadrilateral also has four sides, but only one of them has a different length (9 cm), while the other three sides are simply 3 times longer than the corresponding sides in the smaller quadrilateral.
So the total length of craft wire used by Samantha is:
4x + 9 + 3x + 3x + 3x
Simplifying this expression, we get:
10x + 9
Hence, the total length of craft wire used by Samantha is:
10x + 9

Show that λ is an eigenvalue of A and find one eigenvector v corresponding to this eigenvalue. A = [6 1 -1]
[ 1 4 1] [4 2 3], λ = 5
v = ____
The eigenvector v corresponding to the eigenvalue λ = 5 is v = [1; 1; 1].
To show that λ = 5 is an eigenvalue of matrix A, we need to find a non-zero vector v such that Av = λv.
Given A = [6 1 -1; 1 4 1; 4 2 3] and λ = 5, we substitute these values into the equation Av = λv:
[6 1 -1; 1 4 1; 4 2 3] * [x; y; z] = 5 * [x; y; z]
This gives us the following system of equations:
6x + y - z = 5x
x + 4y + z = 5y
4x + 2y + 3z = 5z
Simplifying each equation, we have:
x - y + z = 0
x - y + z = 0
x - y + z = 0
Notice that all three equations are the same. This implies that the system has infinitely many solutions, meaning there are infinitely many eigenvectors corresponding to the eigenvalue λ = 5.
We can choose any non-zero vector that satisfies the equation, such as v = [1; 1; 1]. Substituting this vector into the equation Av = λv:
[6 1 -1; 1 4 1; 4 2 3] * [1; 1; 1] = 5 * [1; 1; 1]
[6 + 1 - 1; 1 + 4 + 1; 4 + 2 + 3] = [5; 5; 5]
[6; 6; 9] = [5; 5; 5]
Both sides of the equation are equal, confirming that v = [1; 1; 1] is an eigenvector corresponding to the eigenvalue λ = 5.

A small software company will bid on a major contract. It anticipates a profit of $10,000 if it gets it, but thinks there is only a 40% chance of that happening. a) What's the expected profit? b) Find the standard deviation for the profit. a) The expected profit is $ (Round to the nearest dollar as needed.) b) The standard deviation is $ (Round to the nearest dollar as needed.)
a)The expected profit is $4,000. b)The standard deviation for the profit is approximately $4,898.98.
a) To calculate the expected profit, we multiply the profit by the probability of it happening:
Expected profit = Profit * Probability
Given:
Profit = $10,000
Probability = 40% = 0.4
Expected profit = $10,000 * 0.4 = $4,000
Therefore, the expected profit is $4,000.
b) To find the standard deviation for the profit, we need more information about the probability distribution of the profit. If we assume that the profit follows a Bernoulli distribution (with only two possible outcomes: getting the contract or not), we can calculate the standard deviation using the formula:
Standard deviation = √(Probability * (1 - Probability) * Profit^2)
Given:
Profit = $10,000
Probability = 40% = 0.4
Standard deviation = √\((0.4 * (1 - 0.4) * $10,000^2)\)
= √(0.4 * 0.6 * $100,000,000)
= √(24,000,000)
≈ $4,898.98
Therefore, the standard deviation for the profit is approximately $4,898.98.

a. The summary of the simulation data only provides estimates about the real system.
b. The process of developing a simulation model of a complex system can be time-consuming.

d. Each simulation run only provides a sample of how t
he real system will operate.
(d.) Each run of the simulation only provides a sample of the actual system's operation.
This assertion is right, not mistaken. Indeed, each simulation run is a sample of the actual system's operation. A single simulation run cannot account for all possible outcomes and variations in the real system because simulations are based on mathematical models and involve random variations.
In order to take into consideration various scenarios and variations, multiple simulation runs are typically carried out.

Find the inverse of 1/2x (show working)
The inverse of the function f(x) = (1/2)x is f^(-1)(x) = 2x.
To find the inverse of a function, we need to switch the roles of x and y and solve for y. Let's follow the steps to find the inverse of the function f(x) = (1/2)x:
Step 1: Replace f(x) with y: y = (1/2)x.
Step 2: Swap x and y: x = (1/2)y.
Step 3: Solve for y: Multiply both sides of the equation by 2 to isolate y: 2x = y.
Step 4: Replace y with f^(-1)(x): f^(-1)(x) = 2x.
Therefore, the inverse of the function f(x) = (1/2)x is f^(-1)(x) = 2x.
We can verify this by composing the function and its inverse. If we apply f(x) followed by f^(-1)(x), we should get the original value of x. Let's check:
f(f^(-1)(x)) = f(2x) = (1/2)(2x) = x.
As expected, the composition of the function and its inverse gives us the original value of x, indicating that we have found the correct inverse.
