1.You can find another name for plane P by using any three points in the

plane that are not on the same line. Hence, the another name for plane P is the plane GAC .

2. The line intersects the plane is EF

3. The two rays in the plane are CB , DB

4. A,B,C are three points in the plane p.

Spanned by two linearly independent vectors, a plane is a doubly ruled surface in two dimensions. Hyperplanes are the result of extending the plane to higher dimensions. The dihedral angle is the angle at which two planes intersect.

Using any three points on the plane that are not on the same line, you can come up with another name for plane P. Therefore, another name for plane P is GAC. The plane is intersected by the line at EF. CB and DB are the two rays in the plane. There are three points in the plane p, A, B, and C.

The farmer creates 36 Fields from his 55 acres of land.

To determine how many fields the farmer creates from his 55 acres of land, we need to divide the total acreage by the size of each field.

Given that each field is 1& acres, we can simplify this measurement to 1.5 acres.

To find the number of fields, we divide the total acreage by the size of each field:

Number of fields = Total acreage / Size of each field

Number of fields = 55 acres / 1.5 acres

To simplify the division, we can express 55 as a fraction with a denominator of 1. This gives us:

Number of fields = 55/1 acres / 1.5 acres

To divide fractions, we multiply the first fraction by the reciprocal of the second fraction. In this case, we have:

Number of fields = (55/1 acres) * (1/1.5 acres)

Now, let's perform the multiplication:

Number of fields = (55 * 1) / (1 * 1.5) acres

Number of fields = 55 / 1.5 acres

To simplify the division, we divide 55 by 1.5:

Number of fields = 36.6667 acres

Since the number of fields must be a whole number, we round down to the nearest whole number. Therefore, the farmer creates 36 fields.

In conclusion, the farmer creates 36 fields from his 55 acres of land.

The total area is given as 30 sq units.

A composite figure is a two-dimensional shape that is made up of two or more simpler shapes, such as squares, rectangles, triangles, circles, or trapezoids. The area of a composite figure is the total amount of space that is enclosed within its boundaries.

To find the area of a composite figure, you need to first identify all of the individual shapes that make up the figure. Then, you can find the area of each shape using the appropriate formula. Finally, you add up the areas of all the shapes to get the total area of the composite figure.

All three reasons (1, 2, and 3) can be valid for using a normal probability model to represent the distribution of sample means.

1, 2, and 3 are correct.We can use a normal probability model to represent the distribution of sample means for the following reasons:

1. The sample is randomly selected. This ensures that each member of the population has an equal chance of being selected, reducing potential biases and allowing the use of a normal probability model.

2. The distribution of the variable in the population is normally distributed. When the population distribution is normal, the distribution of sample means will also be normally distributed, as stated by the Central Limit Theorem.

3. The sample size is large enough to ensure that sample means will be normally distributed. As the sample size increases, the distribution of sample means approaches a normal distribution, even if the original population distribution is not normal. This is also part of the Central Limit Theorem, which typically suggests a sample size of 30 or more.

What is Volume of a cylinder ?

The formula for calculating the volume of a cylinder is expressed as:

V = \(\pi\)\(r^{2}\)h

where:

r is the radius

h is the height

Given the following parameters

r =  0.75ft

h = 45ft

Get the volume of the cylinder

V = \(\pi\)\(r^{2}\)h

V = (3.14)(0.75)(0.75)(45)

V = 79.4815\(ft^{3}\).

If the wood costs $15.58 per cubic foot, hence the cost of the wood will be 79.4815 * 15.58 = $1,238.32177

Hence , The cost of the wood will be $1,238.32177

To find the series solution for the differential equation y'' + 2xy' + 2y = 0, we can assume a power series solution of the form:

Now, substitute y(x), y'(x), and y''(x) into the differential equation:

∑(n=0 to ∞) aₙn(n-1) xⁿ⁻² + 2x ∑(n=0 to ∞) aₙn xⁿ⁻¹ + 2 ∑(n=0 to ∞) aₙxⁿ = 0

We can simplify this equation by combining the terms with the same powers of x. Let's manipulate the equation step by step:

We can combine the three summations into a single summation:

∑(n=0 to ∞) (aₙ₊₂(n+1)n + 2aₙ₊₁ + 2aₙ) xⁿ = 0

Since this equation holds for all values of x, the coefficients of the terms must be zero. Therefore, we have:

The integrals, we get:
∫0^0.5 (10x - 9) dx = [(5x^2) - (9x)]0^0.5 = 0.625
∫0.5^1 (5 - 9) dx = [(5x) - (9x)]0.5^1 = -1.25
Area(R) = 0.625 - 1.25 = -0.625

Since area cannot be negative, we must have made an error in our calculations. Looking back at the sketch, we see that the region R is actually above the x-axis, and so we must have made an error in evaluating the integral for the part between the parabola and the line y = 9. The correct integral for this part is:

∫0.5^1 (10x - 9) dx = [(5x^2) - (9x)]0.5^1 = 0.625

The volume of the cylindrical tank for refrigerant with an inside diameter of 14 inches and a height of 16 inches is 10,736 cubic inches.

The volume of a cylinder can be calculated using the formula:

\(\[ V = \pi r^2 h \]\)

where V represents the volume, \(\(\pi\)\) is a mathematical constant approximately equal to 3.14159, r is the radius of the cylinder (which is half the diameter), and h is the height of the cylinder.

In this case, the inside diameter of the tank is given as 14 inches, so the radius can be calculated as \(\(r = \frac{14}{2} = 7\)\) inches. The height of the tank is given as 16 inches. Substituting these values into the formula, we get:

\(\[ V = 3.14159 \times 7^2 \times 16 \approx 10,736 \text{ cubic inches} \]\)
