The second solution of the given differential equation t^2y''+2ty'-2y=0, t>0 is y_2(t) = c/t where c is an arbitrary constant.

The second solution of the given differential equation t^2y''+2ty'-2y=0, t>0 is y_2(t) = c/t where c is an arbitrary constant.

y_2(t) = t^2v'(t) + 2t v(t) - y_1(t)

Substituting y_1(t) and y_2(t) in the given equation, we get

t^2v''(t) + 2tv'(t) - 2v(t) = 0

This is a first order linear differential equation and can be solved as

v'(t) = -2v(t)/t

Integrating both sides, we get

v(t) = c/t^2

Therefore, the second solution of the given equation is

y_2(t) = c/t

The second solution of the given differential equation t^2y''+2ty'-2y=0, t>0 is y_2(t) = c/t where c is an arbitrary constant.

According to the question of equilateral triangles, 6.7√3 cm is the vertical height of the hexagon.

An equilateral triangle is a triangle with all three sides having the same length and all three angles measuring 60 degrees. It is one of the three basic shapes in geometry and is considered to be the most symmetrical triangle. The sides of an equilateral triangle are always congruent, meaning all three sides have the same length. The sides of an equilateral triangle are also always perpendicular, meaning all three angles are equal to 60 degrees. The area of an equilateral triangle can be calculated using the formula A = (1/2)bh, where b is the length of the base and h is the length of the height.

The vertical height of the hexagon can be calculated using the Pythagorean Theorem. The length of each side of the equilateral triangle is x/2 and the height of the triangle is x√3/2.

The total vertical height of the hexagon is therefore 6 x x√3/2, which is equal to 6.7√3 cm.

Trigonometry is the study of relationships between angles and sides of a triangle.

The six trigonometric functions—sine (sin), cosine (cos), tangent (tan), cosecant (csc), secant (sec), and cotangent (cot)—are used to describe the relationships between the angles and sides of any triangle.

The unit circle is a circle of radius one centered at the origin of a Cartesian coordinate system. When we determine the coordinates of points on the unit circle, we are using the six trigonometric functions. The unit circle is used to find the values of the trigonometric functions for angles of measures 0°, 30°, 45°, 60°, and 90°.

In the interval [0, 2π], we can use the unit circle to calculate the trigonometric functions of the angles in both degrees and radians. For example, sin 0° = 0, cos 0° = 1, tan 0° = 0, csc 0° = undefined, sec 0° = 1, cot 0° = undefined. The corresponding values in radians are sin 0 = 0, cos 0 = 1, tan 0 = 0, csc 0 = undefined, sec 0 = 1, cot 0 = undefined.

By using the unit circle, we can find the value of all six trigonometric functions for any angle in the interval [0, 2π], given in degrees or radians. We can also use the unit circle to find the trigonometric functions for any angle in any interval.

The answer is D. I and II only. The number of people who chose A as their favorite brand could be 30 or 35 since x is rounded to the nearest integer, which is 3. However, it cannot be 45 since 3 is the nearest integer.

1. x is rounded to the nearest integer, which is 3

2. If x is equal to 30, then the number of people who chose A as their favorite brand would be 30

3. If x is equal to 35, then the number of people who chose A as their favorite brand would be 35

4. If x is equal to 45, then the number of people who chose A as their favorite brand would be 45

5. Since 3 is the nearest integer, the number of people who chose A as their favorite brand cannot be 45

6. Therefore, the answer is D. I and II only.

1,150 respondents were asked to select their preferred brand among brands A, B, and C of laundry detergent. x% of those polled indicated that A was their preferred brand. The outcome is 3 if x is rounded to the nearest integer. This means that x could be 30, 35, or 45. However, since 3 is the nearest integer, the number of people who chose A as their favorite brand cannot be 45. Therefore, the answer is D. I and II only, meaning that the number of people who chose A as their favorite brand could be 30 or 35. This is because if x is equal to 30, then the number of people who chose A as their favorite brand would be 30 and if x is equal to 35, then the number of people who chose A as their favorite brand would be 35.

The lowest possible value of R² is 0 and the highest possible value is 1. Put simply, the better a model is at making predictions, the closer its R² will be to 1.

The coefficient of determination (R²) measures how well a statistical model predicts an outcome. The outcome is represented by the model’s dependent variable.

The lowest possible value of R² is 0 and the highest possible value is 1. Put simply, the better a model is at making predictions, the closer its R² will be to 1.

Suppose that you perform a simple linear regression that predicts students’ exam scores (dependent variable) from their time spent studying (independent variable).

If the R2 is 0, the linear regression model doesn’t allow you to predict exam scores any better than simply estimating that everyone has an average exam score.

If the R2 is between 0 and 1, the model allows you to partially predict exam scores. The model’s estimates are not perfect, but they’re better than simply using the average exam score.

If the R2 is 1, the model allows you to perfectly predict anyone’s exam score.

The area of the shaded region is 36.

Step-by-step explanation:

First, let's find the area of the rectangle as a whole, which will be 5*10 = 50. How did we get 50? The right side is 5 (from 2+3), and the top is 10 (3+7). Multiplying those numbers together will give you the area.

Now, the problem asks to find the shaded region. Let's solve for the area of the non-shaded region: (7*2) = 14.

Now, we can subtract the whole rectangle area minus the non-shaded region to find the shaded region:

50 - 14 = 36

fx = (cos(12(0.2)) - cos(3(0.2)))/(0.2)^2

fx = (cos(2.4) - cos(0.6))/0.04

fx = (0.92358 - 0.95105)/0.04

fx = -24.987664

Step 2: Calculate the value of the function for x=0.1

fx = (cos(12(0.1)) - cos(3(0.1)))/(0.1)^2

fx = (cos(1.2) - cos(0.3))/0.01

fx = (0.9589 - 0.9511)/0.01

fx = -98.998848

Step 3: Calculate the value of the function for x=0.05

fx = (cos(12(0.05)) - cos(3(0.05)))/(0.05)^2

fx = (cos(0.6) - cos(0.15))/0.0025

fx = (0.9802 - 0.9657)/0.0025

fx = -19.923683

Step 4: Calculate the value of the function for x=0.01

fx = (cos(12(0.01)) - cos(3(0.01)))/(0.01)^2

fx = (cos(0.12) - cos(0.03))/0.0001

fx = (0.9999 - 0.9998)/0.0001

fx = -99.853172

Step 5: Calculate the value of the function for x=0.001

fx = (cos(12(0.001)) - cos(3(0.001)))/(0.001)^2

fx = (cos(0.012) - cos(0.003))/0.000001

fx = (0.999983 - 0.999971)/0.000001

fx = -998.62855

Step 6: Calculate the value of the function for x=0.0001

fx = (cos(12(0.0001)) - cos(3(0.0001)))/(0.0001)^2

fx = (cos(0.0012) - cos(0.0003))/0.00000001

The ΔBAE is congruent to ΔDAE. ΔBAE and ΔDAE have three corresponding angles that are congruent, so they are congruent.

The Triangle Congruence Theorem states that if two triangles have three corresponding angles that are congruent, then the triangles are congruent.

This can be seen by looking at the angles BAE, BAE, and DAE. All three of these angles are equal, so they are congruent. Additionally, the side lengths of the triangles are the same, so the triangles are also congruent. The Triangle Congruence Theorem is an important tool for determining the congruence of two triangles.

It is used to compare the angles and side lengths of two triangles, and if the angles and side lengths are the same, then the triangles are congruent. When ΔBAE and ΔDAE have the same angles and side lengths, then it is clear that they are congruent.
