Write an equation of the altitude from vertex A.

Answer:

x = 1

y = -1

Step-by-step explanation:

y = 3x + 4y

3x + 3y = 0

So, we have 2 equations that are

3x + 3y = 0

x + 2y = -1

Times the second equation by -3

3x + 3y = 0

-3x - 6y = 3

-3y = 3

y = -1

Now put -1 in for y and solve for x

x + 2(-1) = -1

x - 2 = -1

x = 1

Let's check

1 + 2(-1) = -1

1 - 2 = -1

-1 = -1

So, x = 1 and y = -1 is the correct answer.

Based on the scatter plot below, better prediction for x when y = 42 is 53.

A scatter plot is a form of plot or mathematical diagram that displays values for two variables for a collection of data using Cartesian coordinates. One more variable can be presented if the points are programmed. A scatter plot is a collection of dots drawn on two axes, horizontal and vertical. Scatter plots are useful in statistics because they illustrate the amount, if any, of correlation between the values of observed quantities or events. Scatter plots are used to demonstrate how much one variable affects another by plotting data points on a horizontal and vertical axis. Each row in the data table is represented by a marker, the location of which is determined by the values in the columns.

The circumference of the circle is given by C = 2 * π * r, where r is the radius. In this case, the circumference of the circle is 2 * π * 14 = 88 cm.

Let's call the linear speed of the object v. Then, in 20 seconds, the object travels a distance of v * 20. This distance is equal to the arc length of the central angle of 1/2 radian:

v * 20 = (1/2) * (C/2π) = (1/2) * (88/2π) = 22/π cm

Solving for v, we get:

v = (22/π) / 20 = 22 / (20π) cm/s

The angular speed ω can be found by dividing the central angle by the time it took to travel that angle:

ω = 1/2 / 20 = 1/40 rad/s

So the linear speed of the object is v = 22 / (20π) cm/s, and the angular speed is ω = 1/40 rad/s.

The matrix D is important because it is the diagonal representation of the matrix A, which makes it easier to work with and understand.

When diagonalizing a matrix, the goal is to find a diagonal matrix (D) that is similar to the original matrix (A). This means that the matrix D will have the same eigenvalues as the matrix A and will be represented in a more simplified form.

To find the matrix D, you must first find the eigenvalues of the matrix A. These eigenvalues can be found by solving the characteristic equation, which is found by setting the determinant of the matrix (A - λI) to zero, where λ is the eigenvalue and I is the identity matrix.

Once the eigenvalues are found, you can then find the eigenvectors, which are non-zero vectors that satisfy the equation

=> Av = λv,

where v is the eigenvector.

Once you have both the eigenvalues and eigenvectors, you can then arrange them into the matrix D, where the eigenvalues are on the main diagonal and the eigenvectors are the columns.

To make sure that D is diagonal, you may need to scale the eigenvectors so that the entries are integers. This is called normalizing the eigenvectors.

The probability that a defective component can be detected by only one inspector is 0.2112. the probability that all three defective components in a batch escape detection by both inspectors is 0.00178.

(a) To calculate the probability that a defective component will be detected by only one inspector, we can use the formula for conditional probability: P(detected by first inspector | not detected by second inspector) = P(detected by first inspector and not detected by second inspector) / P(not detected by second inspector).

The probability that a defective component will be detected by the first inspector and not detected by the second inspector can be calculated as follows: P(detected by first inspector and not detected by second inspector) = P(detected by first inspector) * P(not detected by second inspector | detected by first inspector) = 0.88 * (1 - 0.88) = 0.1056.

The probability that a defective component will not be detected by the second inspector is: P(not detected by second inspector) = 1 - P(detected by second inspector) = 1 - 0.88 = 0.12.

The probability that a defective component will be detected by exactly one of the two inspectors can be calculated as follows: P(detected by exactly one inspector) = P(detected by first inspector and not detected by second inspector) + P(detected by second inspector and not detected by first inspector) = 0.1056 + 0.1056 = 0.2112.

(b) To calculate the probability that all three defective components in a batch escape detection by both inspectors, we can use the formula for independent events: P(all three defective components escape detection) = P(first defective component escapes detection) * P(second defective component escapes detection) * P(third defective component escapes detection) = (1 - 0.88)^3 = 0.00178.

So the probability that all three defective components in a batch escape detection by both inspectors is 0.00178.

Answer:

To show that all three medians of a triangle intersect at the same point, we can use the property that the midpoint of each median is the centroid of the triangle.

The centroid of a triangle is a point that is two thirds of the distance from each vertex to the midpoint of the opposite side. This means that the centroid divides each median in a 2:1 ratio, with two thirds of the median length being on one side of the centroid and one third on the other side.

Since the centroid is the same for all three medians, it follows that all three medians must intersect at the same point, which is known as the centroid or the center of gravity of the triangle. This point is denoted by the letter G.

Therefore, we can conclude that all three medians of triangle ABC intersect at point G, which is the centroid of the triangle.

Answer:  The length of AC is approximately 5.196 units.

Step-by-step explanation:

To find the length of AC, we can use the fact that DE is parallel to AC and AD is parallel to FE, which forms a pair of corresponding angles. Therefore, we can set up a proportion using the fact that corresponding angles are congruent.

DE/AC = AD/FE

We know that DE = 5 and AD = 6, so we can substitute these values into the proportion:

5/AC = 6/FE

We can cross-multiply and solve for AC:

5 * FE = 6 * AC

Next, using the fact that triangle ABC is a triangle, we can use the Pythagorean theorem to find the value of FE.

AB^2 + BC^2 = AC^2

17^2 + BC^2 = (AC)^2

289 + BC^2 = AC^2

Now, substitute the value of FE into the equation we have,

5 * sqrt(AC^2 - 289) = 6 * AC

multiply the both sides of the equation by the reciprocal of 5,

sqrt(AC^2 - 289) = (6/5) * AC

Square both sides of the equation,

AC^2 - 289 = 36/25 * AC^2

subtract the left side from the right side

-289 = -(36/25) * AC^2

divide both sides by -(36/25)

AC = sqrt(289/(1-(36/25)))

AC = sqrt(289/11/25)

AC = sqrt(289/275)

AC = sqrt(289/11)

AC = sqrt(26)

AC = approx 5.196152422706632

Therefore, the length of AC is approximately 5.196 units.

If Maria uses 2 parts cream and 3 parts milk, then for every 2 parts of cream, she uses 3 parts of milk.

Since she uses 8 liters of cream, we can find the total volume of mixture by finding the equivalent volume of milk that she used.

To find the equivalent volume of milk, we multiply the volume of cream by the ratio of milk to cream:

8 liters * (3 parts milk) / (2 parts cream) = 12 liters

So Maria used 8 liters of cream and 12 liters of milk for a total volume of 20 liters.

If a patient took 400 mg of acetaminophen which has the half life of 4 hour, the amount of acetaminophen that will be in the patient is:

The half-life of acetaminophen is 4 hours, which means that every 4 hours, half of the initial dose of 400 mg will still remain in the patient's body.

At 4 hours after taking the dose, the amount of acetaminophen in the patient's body would be:

400 mg / 2 = 200 mg

At 2 hours after taking the dose, the amount of acetaminophen in the patient's body would be:

400 mg / (2^(4/4)) = 200 mg / 2 = 100 mg

At 1 hour after taking the dose, the amount of acetaminophen in the patient's body would be:

400 mg / (2^(4/4)) = 100 mg / 2 = 50 mg

In conclusion, the amount of acetaminophen in the patient's body decreases by half every 4 hours.
