Write an equation (4,-2) (3,6)

The given statement exists true. A matrix is broken down into orthogonal (Q) and upper triangular (R) matrices in a process known as QR decomposition (factorization).

A matrix can be expressed as the union of two distinct matrices, Q and R, using the QR matrix decomposition. R is a square upper/right triangular matrix and Q is an orthogonal matrix. R is also invertible because it is square and doesn't have zeros in its diagonal entries.

A matrix is broken down into orthogonal (Q) and upper triangular (R) matrices in a process known as QR decomposition (factorization). Finding eigenvalues and solving linear least squares problems both use QR factorization.

A = QR. Be aware that the QR-factorization of a rectangular matrix A is sometimes understood with Q square and R rectangular rather than Q rectangular and R square, as with the MATLAB command qr.

according to question the values of sin(θ) and tan(θ) are:

sin(θ) = sqrt(33)/7

tan(θ) = -sqrt(33)/4

Given that cos(θ) = -4/7, we can use the Pythagorean identity to find sin(θ):

sin²(θ) + cos²(θ) = 1

sin²(θ) = 1 - cos²(θ)

sin(θ) = ± sqrt(1 - cos²(θ))

Since the angle θ is in the second quadrant (cosine is negative and sine is positive), we choose the positive value for sin(θ):

sin(θ) = sqrt(1 - cos²(θ))

sin(θ) = sqrt(1 - (-4/7)²)

sin(θ) = sqrt(1 - 16/49)

sin(θ) = sqrt(33/49)

sin(θ) = sqrt(33)/7

Now, we can use the definition of tangent to find tan(θ):

tan(θ) = sin(θ) / cos(θ)

Substituting the values we have:

tan(θ) = (sqrt(33)/7) / (-4/7)

tan(θ) = -sqrt(33)/4

what is quadrant?

In geometry, a quadrant is one of the four regions into which a coordinate plane is divided by the x-axis and y-axis. Each quadrant is named based on the signs of the coordinates in that region.

The four quadrants are:

First quadrant: It is located in the upper-right part of the coordinate plane, where both x and y coordinates are positive.

Second quadrant: It is located in the upper-left part of the coordinate plane, where x-coordinates are negative and y-coordinates are positive.

Third quadrant: It is located in the lower-left part of the coordinate plane, where both x and y coordinates are negative.

Fourth quadrant: It is located in the lower-right part of the coordinate plane, where x-coordinates are positive and y-coordinates are negative.

Step-by-step explanation:

Answer:

A = 1/2 b * h

b = 2A / h

b = 12

Step-by-step explanation:

Remark

The formula starts out as

A = 1/2 * b * h  

You want to rearrange it to show b by itself.

Formula

Multiply by 2

2A = b * h            

Divide by h

2A/h = b

Part C

b = 2A / h

A = 36 mm^2

h = 6 mm

b = 2*36 / 6

b = 72 / 6

b = 12 mm

The total US dollars it cost to Tom to get the rupees he wants for the trip of India is $270 round to the nearest dollar.

Percentage of a number is the part of the number expressed in the in every hundred. Percentage of a number is expressed with the symbol '%'.

To calculate the percentage part of number, multiply it with the original number and divide with 100.

Tom is exchanging money for his trip to india. The exchange rate of us dollars to indian rupees is,

\(r=\dfrac{1}{45.897}\)

Tom needs 11,550 rupees. The dollars need for 11550 Indian rupees are,

\(n=\dfrac{11550}{45.897}\\n=251.65\)

The currency exchange service he is using charges a fee of 7.25% after the exchange is made. Thus the total dollar requied after the service charge is,

\(n=251.65+\dfrac{7.25}{100}\times251.65\\n=251.65+18.245\\n=269.895\\n\approx270\)

Thus, the total US dollars it cost to Tom to get the rupees he wants for the trip of India is $270 round to the nearest dollar.

A consumer loan of $40,000 with a 15.8% interest rate will require monthly payments over a period of 2 years. The total amount to be paid, including both principal and interest, will be approximately $45,380.

To calculate the monthly payments, we need to determine the total amount to be paid over the loan period, including the principal amount and the interest. The formula used for calculating equal monthly installments is:

M = P * (r * (1 + r)^n) / ((1 + r)^n - 1)

Where:

M = Monthly payment

P = Principal amount

r = Monthly interest rate

n = Number of monthly payments

In this case, the principal amount (P) is $40,000, the interest rate (r) is 15.8% per year, and the loan duration (n) is 2 years (24 months).

First, we convert the annual interest rate to a monthly rate by dividing it by 12: 15.8% / 12 = 0.0132.

Next, we substitute the values into the formula:

M = 40,000 * (0.0132 * (1 + 0.0132)^24) / ((1 + 0.0132)^24 - 1)

Calculating this formula gives us the monthly payment (M) of approximately $1,907.42.

To find the total amount to be paid, we multiply the monthly payment by the number of payments: $1,907.42 * 24 = $45,778.08. However, this includes both the principal and the interest. Subtracting the principal amount ($40,000) gives us the total interest paid: $45,778.08 - $40,000 = $5,778.08.

Therefore, the total amount to be paid, including both principal and interest, will be approximately $45,778.08.

To find the gradient of the function f(x, y) = x/y, we need to calculate the partial derivatives of f with respect to x and y.

Calculate the partial derivative with respect to x: ∂f/∂x. To do this, differentiate the function f(x, y) = x/y with respect to x, treating y as a constant. This gives ∂f/∂x = 1/y.

Calculate the partial derivative with respect to y: ∂f/∂y. To do this, differentiate the function f(x, y) = x/y with respect to y, treating x as a constant. This gives ∂f/∂y = -x/y^2.

Write the gradient vector: The gradient of f is the vector formed by the partial derivatives ∂f/∂x and ∂f/∂y. So, the gradient vector ∇f(x, y) = (∂f/∂x, ∂f/∂y) = (1/y, -x/y^2).

Evaluate the gradient at point P(6, 1): Substitute x = 6 and y = 1 into the gradient vector ∇f(x, y). This gives ∇f(6, 1) = (1/1, -6/1^2) = (1, -6).

Multiply the gradient vector by the given vector u: Multiply the gradient vector ∇f(6, 1) = (1, -6) by the vector u = 3i + 5j. This gives (1 * 3) + (-6 * 5) = 3 - 30 = -27.

The result of the dot product is the directional derivative of f in the direction of vector u at point P(6, 1). Therefore, the gradient of f at point P is -27.

It is important to consider the scale of measurement and the specific characteristics of the variables when selecting an appropriate statistical test.The tests can be classified as follows:

1. A researcher measures the proportion of schizophrenic patients born in each season.

This test is nonparametric. The scale of measurement is categorical, as the seasons (spring, summer, fall, winter) represent distinct categories rather than continuous numerical values. Therefore, parametric assumptions, such as normality and equal variances, do not apply to this measurement.

2. A researcher measures the average age that schizophrenia is diagnosed among male and female patients.

This test is parametric. The scale of measurement is continuous and numerical (age in years). Parametric tests, such as t-tests or ANOVA, can be applied when working with continuous data, assuming the data meet the required assumptions (e.g., normality, independence, and equal variances).

3. A researcher tests whether frequency of Internet use and social interaction are independent.

This test can be both parametric or nonparametric, depending on the measurement scale and the specific statistical test used. If the variables are measured on a nominal or ordinal scale, nonparametric tests, such as the chi-square test, would be appropriate. If the variables are measured on a continuous scale, parametric tests, such as logistic regression, could be employed.

4. A researcher measures the amount of time (in seconds) that a group of teenagers uses the Internet for school-related and non-school-related purposes.

This test is parametric. The scale of measurement is continuous (time in seconds), and parametric tests, such as t-tests or ANOVA, can be utilized to compare means or variances, assuming the required assumptions are met.

The No Information Rate (NIR) is a measure of the accuracy of a classification model that predicts the most frequent class as the outcome for all cases.

In statistics, the No Information Rate (NIR) is a measure of the accuracy of a classification model that predicts the most frequent class as the outcome for all cases. It represents the accuracy rate that can be achieved by simply guessing the most frequent outcome without using any predictive model or variable.

The NIR is commonly used as a benchmark for evaluating the performance of classification models, as any model that performs worse than the NIR is considered to be poorly performing. Conversely, a model that performs better than the NIR is considered to have some predictive power beyond simply guessing the most frequent outcome.
