The points (x, y, z), (1, 1, 0), and (1, 2, 1) lie on a plane through the origin, then the determinant is zero

Since the plane passes through the root, any two vectors on the plane must be directly autonomous. In this manner, we will utilize the vectors (1, 1, 0) and (1, 2, 1) to discover the condition of the plane.

A vector opposite to the plane can be found by taking the cross item of the two vectors:

(1, 1, 0) × (1, 2, 1) = (-1, 1, 1)

The condition of the plane can be composed as:

x + y + z = d

where d may be steady to be decided. We are able to utilize one of the focuses on the plane, such as (1, 1, 0), to discover d:

1 + 1 + = d

d = 0

In this manner, the condition of the plane is:

x + y + z = 0

 To check that the point (x, y, z) = (1, 2, 1) lies on this plane, we will substitute these values into the condition over   

  1 + 2 + 1 = 0

 which is genuine, so the point lies on the plane.

To discover the determinant that is zero, we will utilize the three focuses (x, y, z), (1, 1, 0), and (1, 2, 1) to make a 3x3 lattice:

| x y z |

| 1 1 0 |

| 1 2 1 |

Growing the determinant along the primary push, we get:

x | 1  0 |

| 2 1 | = x(1 - 0) - y(1 - 0) + z(2 - 1) = x - y + z

Subsequently, the determinant is:

x - y + z

Since these three focuses lie on a plane through the root, they fulfill the condition:

x + y + z = 0

 Substituting z = -x + y into the expression for the determinant over, we get:

x - y + (-x + y) = 0

 Streamlining, we get:  

 0=0  

 Subsequently, the determinant is zero, as anticipated.

The measure of the differences of all observations from the mean, expressed as a single number is called the "standard deviation". It is a commonly used measure of the amount of variability or dispersion within a set of data.

The standard deviation is calculated by taking the square root of the variance, which is the average of the squared differences between each observation and the mean.

It is expressed in the same units as the data itself, and provides a way to understand how spread out the data is from the average or mean value.

A small standard deviation indicates that the data points tend to be close to the mean, while a large standard deviation indicates that the data points are more spread out.

The standard deviation can be used to compare the variability of different sets of data, and can also be used in statistical tests to determine if the difference between two sets of data is statistically significant.

The area of the region y = 18x² - 6x - 72, bounded by the curve x-axis and lines x = -3 and x = 3 is equal to -54 square units.

To find the area of the region bounded by the curve y = 18x² - 6x - 72, the x-axis, and the lines x = -3 and x = 3,

Use definite integration.

The area can be calculated by integrating the absolute value of the function y = 18x² - 6x - 72 over the interval [-3, 3].

To find the area, use the following integral,

A = ∫₋₃³ |18x² - 6x - 72| dx

Let's break down the integral into two parts, as the function inside the absolute value changes sign at the roots,

A = ∫₋₃³(18x² - 6x - 72) dx + ∫₋₃³ (-18x² + 6x + 72) dx

Now, integrate each part separately,

For the first part, integrating (18x² - 6x - 72) dx from -3 to 3,

∫₋₃³ (18x² - 6x - 72) dx

= [6x³ - 3x² - 72x] [-3 to 3]

= [(6(3)³ - 3(3)² - 72(3)) - (6(-3)³ - 3(-3)² - 72(-3))]

= [162 - 54 - 216] - [(-162) - 54 + 216]

= -54 - 162 - 54 + 216

= -54

For the second part, integrating (-18x² + 6x + 72) dx from -3 to 3,

∫₋₃³ (-18x² + 6x + 72) dx = [-6x³ + 3x² + 72x] [-3 to 3]

= [(-6(3)³ + 3(3)² + 72(3)) - (-6(-3)³ + 3(-3)² + 72(-3))]

= [(-162 + 27 + 216) - (-162 + 27 - 216)]

= 54 + 162 - 54 - 162

= 0

Adding the two parts together,

A = -54 + 0

  = -54

Therefore, the area of the region bounded by the curve y = 18x² - 6x - 72, the x-axis, and the lines x = -3 and x = 3 is -54 square units.

λ = 2 is not an eigenvalue of multiplicity two for the given differential equation y'' + y = 0.

To show that λ = 2 is an eigenvalue of multiplicity two for the given differential equation y'' + y = 0, we need to find the corresponding eigenvectors.

Let's start by assuming that y = e^(rx) is a solution to the differential equation, where r is a constant.

Substituting this assumption into the differential equation, we get:

y'' + y = 0

(r^2 e^(rx)) + e^(rx) = 0

Dividing through by e^(rx), we have:

r^2 + 1 = 0

Solving this quadratic equation for r, we find:

r = ±i

So, the solutions to the differential equation are of the form:

y = C1 e^(ix) + C2 e^(-ix)

Using Euler's formula, we can express this as:

y = C1 (cos(x) + i sin(x)) + C2 (cos(x) - i sin(x))

y = (C1 + C2) cos(x) + (C1 - C2) i sin(x)

Now, let's consider the initial conditions y(0) = y'(0) = 1:

Substituting x = 0 into the equation, we get:

y(0) = C1 + C2 = 1  ---- (1)

Differentiating y with respect to x, we have:

y' = -(C1 - C2) sin(x) + (C1 + C2) i cos(x)

Substituting x = 0 into the equation, we get:

y'(0) = C1 i + C2 i = i  ---- (2)

From equation (1), we have C1 = 1 - C2.

Substituting this into equation (2), we get:

i = (1 - C2) i + C2 i

0 = 1 - C2 + C2

0 = 1

This equation is not satisfied, which means that there is no unique solution that satisfies both initial conditions y(0) = 1 and y'(0) = i.

Yes, it is possible to have a function f defined on [2, 3] that meets the given conditions. To satisfy the condition of not being continuous on [2, 3], we can create a function with a removable discontinuity at a specific point.

One way to achieve this is by defining f(x) as a piecewise function. We can let f(x) be equal to a constant value c for x in [2, a) and [a, 3], where a is a value between 2 and 3. This will create a hole in the graph of the function at x = a, resulting in a removable discontinuity.

To ensure that f takes on both a maximum and minimum value, we can choose different constant values for f(x) in the intervals [2, a) and [a, 3]. For example, we can let f(x) be a high value like 100 in [2, a) and a low value like -100 in [a, 3]. This way, f(x) will have a maximum value of 100 and a minimum value of -100.

The group of volunteers can make a total of 200 masks out of 25 yards of fabric.

To calculate the number of masks that can be made, we divide the total amount of fabric (25 yards) by the amount of fabric required per mask (1/8 yard). To do this, we first convert the fraction 1/8 to decimal form, which is 0.125. Then, we divide the total fabric (25 yards) by the fabric required per mask (0.125 yards). This can be done by dividing 25 by 0.125, which equals 200. Therefore, the group of volunteers can make a total of 200 masks out of 25 yards of fabric. Each mask requires 1/8 yard of fabric, so dividing the total fabric by the fabric required per mask gives us the total number of masks that can be made.

Calculation steps:
1. Convert the fraction 1/8 to decimal form: 1/8 = 0.125.
2. Divide the total fabric (25 yards) by the fabric required per mask (0.125 yards):

Markus scored 82 on his fifth test.

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.

We know that Markus' score on the fifth test is 5 points lower than the average of all five tests. Let x be the score Markus got on his fifth test. Then the average score of all five tests is:

(85 + 92 + 82 + 94 + x)/5

So the equation to determine Markus' score on the fifth test is:

x = (85 + 92 + 82 + 94 + x)/5 - 5

Simplifying this equation, we can first add the numbers in the numerator:

x = (353 + x)/5 - 5

Next, we can multiply both sides by 5 to eliminate the denominator:

5x = 353 + x - 25

Simplifying further, we can combine like terms:

4x = 328

Finally, we can solve for x by dividing both sides by 4:

x = 82

Therefore, the correct equation for Markus to determine his score on the fifth test is:

4(x - 5) = 353 + x.
