Square both sides:

\(\\ \tt\Rrightarrow \sqrt{x}=3\)

\(\\ \tt\Rrightarrow x=3^2\)

\(\\ \tt\Rrightarrow x=3(3)\)

\(\\ \tt\Rrightarrow x=9\)

Answer:

The area will be:

\(A=18(1+\sqrt{3}) \: u^{2}\) or \(A=49.18 \: u^{2}\).

Step-by-step explanation:

Using the definition of tangent, we have:

\(tan(\alpha)=\frac{6}{\vec{AB}}\)

We know that tan(α) = 1, then we can find AB

\(1=\frac{6}{\vec{AB}}\)

\(\bar{AB}=6\: u\)

u means any unit.

Now, we need to find the distance BC. If the angle ∠D is 60°, then ∠C must be 30°. Using the tangent definition in the triangle BCD we have:

\(tan(30)=\frac{6}{\bar{BC}}\)

\(\bar{BC}=\frac{6}{tan(30)}\)

\(\bar{BC}=\frac{6}{1/\sqrt{3}}\)

\(\bar{BC}=6\sqrt{3} \: u\)

So, the base of the triangle will be:

\(b=\bar{AB}+\bar{BC}=6+6\sqrt{3}=6(1+\sqrt{3}) \: u\)

The area of a triangle is given by the following equation:

\(A=\frac{b*h}{2}\)

\(A=\frac{6(1+\sqrt{3})*6}{2}\)

\(A=18(1+\sqrt{3})\)

Therefore, the area will be \(A=49.18 \: u^{2}\).

The product of matrices A and B, denoted as C = AB, is determined by performing matrix multiplication using the given matrices. In this case, A is a 2x1 matrix and B is a 1x3 matrix. The resulting matrix C will have dimensions 2x3.

To find the product of matrices A and B, we perform matrix multiplication by multiplying corresponding elements and summing the results.

The dimensions of the matrices must be compatible for multiplication, meaning the number of columns in the first matrix must match the number of rows in the second matrix.

Given matrices A and B:

A = [9 1]

B = [2 6 7]

To calculate C = AB, we multiply each element of A with the corresponding element in B, and then sum the results. The resulting matrix C will have dimensions 2x3.

C = [92 + 13 96 + 16 97 + 15]

Calculating each element of C, we have:

C = [18 + 3 54 + 6 63 + 5]

[21 60 68]

Simplifying, we get:

C = [21 60 68]

Therefore, the product of matrices A and B, denoted as C = AB, is the matrix:

C = [21 60 68]

An equation of the cone z = √3x² + 3y² in spherical coordinates is: None of these. A cone is formed by rotating a straight line around an axis when one end of the straight line remains fixed.

For example, if the equation of a cone is known, we may use calculus to calculate the cone's volume and surface area. Cone: A cone is a three-dimensional geometric shape that has one circular base at one end and a single point at the other end. A cone's height is the distance from the tip to the base surface's center. The angle formed between the slant height and the base radius is called the cone's half-angle. The vertical plane that passes through the cone's apex and base centerline is called the cone's axis.

Spherical coordinates: In three-dimensional space, spherical coordinates are a coordinate system. Three parameters, the radial distance r, the polar angle θ, and the azimuthal angle φ, are used to specify the position of a point using spherical coordinates. In this case, the radial distance, which is the distance from the origin, is r, and the polar angle and azimuthal angles are represented by θ and φ, respectively. Let D be the region bounded by the two paraboloids z = 2x² + 2y² - 4 and z = 5 - x² - y² where x² + y² ≤ 4.

The cylindrical coordinate system is a three-dimensional coordinate system that uses cylindrical polar coordinates to specify a point in space. Cylindrical coordinates are a generalization of two-dimensional polar coordinates, which are used to define a point in the plane. The integral that allows us to calculate the volume of the region is given by: ar dzdrde. Let D be the region in the first octant enclosed by the two spheres x² + y² + z² = 4 and x² + y² + z² = 25. The integral that allows us to calculate the volume of the region is given by: p²sinodpdode.

The lexicographic preferences on apricots and bananas are transitive. They cannot be represented by a continuous utility function u(a, b).

1. To prove that the lexicographic preferences on apricots and bananas are transitive, let's assume the following:
(x1, y1)≻(x2, y2) (x2, y2)≻(x3, y3)

That implies the following:
1. x1 > x2 or (x1 = x2 and y1 > y2)
2. x2 > x3 or (x2 = x3 and y2 > y3)

Therefore, we have two cases:

Case 1: x1 > x2 > x3

If this is true, then we have

(x1, y1) > (x3, y3),

and the lexicographic preferences are transitive.

Case 2: x1 = x2 > x3

If this is true, then

y1 > y2, and x2 = x3,

which means

y2 > y3.

Therefore, (x1, y1) > (x3, y3), and the lexicographic preferences are transitive.

2. Now we need to prove that the lexicographic preferences on apricots and bananas cannot be represented by a continuous utility function u(a,b).

Suppose that there exists a continuous utility function u(a,b) that represents the lexicographic preferences on apricots and bananas.

Therefore, (a1, b1) ≻ (a2, b2) if and only if u(a1, b1) > u(a2, b2).

Let's consider two cases:

Case 1: a1 > a2.

Since

u(a1, b1) > u(a2, b2),

we have:

u(a1, b1) - u(a2, b2) > 0,

which means that

Δu = u(a1, b1) - u(a2, b2) > 0

Case 2: a1 = a2 and b1 > b2.

Since

u(a1, b1) > u(a2, b2),

we have:

u(a1, b1) - u(a2, b2) > 0,

which means that

Δu = u(a1, b1) - u(a2, b2) > 0

Therefore, we have Δu > 0 in both cases, which contradicts the fact that the lexicographic preferences on apricots and bananas are non-continuous.

Hence, they cannot be represented by a continuous utility function u(a,b).

In conclusion, the lexicographic preferences on apricots and bananas are transitive but cannot be represented by a continuous utility function.

To find f(x), we need to solve the given differential equation and use the initial condition of the y-intercept, so f(x) = \(e^(9x^7 + ln|2|)\).

The given differential equation is: dy/dx = 63\(yx^6\).

Separating variables, we have: dy/y = 63\(x^6\) dx.

Integrating both sides, we get: ln|y| = 9\(x^7\)+ C, where C is the constant of integration.

To determine the value of C, we use the y-intercept condition. When x = 0, y = 2. Substituting these values into the equation:

ln|2| = 9(0)\(^7\) + C,

ln|2| = C.

So, C = ln|2|.

Substituting C back into the equation, we have: ln|y| = 9\(x^7\)+ ln|2|.

Exponentiating both sides, we get: |y| = \(e^(9x^7 + ln|2|)\).

Since y = f(x), we take the positive solution: \(y = e^(9x^7 + ln|2|)\).

Therefore, f(x) = \(e^(9x^7 + ln|2|)\).

The minimum sample size needed to estimate the proportion of U.S. adults supporting the proposed amendment with a 95% c

To determine the sample size needed for estimating the proportion of U.S. adults supporting the proposed amendment to the constitution with a confidence level of 95% and a margin of error of 4%, we can use the formula:

n = (Z^2 * p * (1 - p)) / (E^2)

Where:

n = sample size

Z = Z-score corresponding to the desired confidence level (95% confidence level corresponds to a Z-score of approximately 1.96)

p = estimated proportion (since we don't have an estimate, we can assume p = 0.5, which provides the maximum sample size required)

E = margin of error (0.04 in this case)

Plugging in the values, we get:

n = (1.96^2 * 0.5 * (1 - 0.5)) / (0.04^2)

n = 600.25 / 0.0016

a. Using the cash basis of accounting, Al's gross income for 2021 is $479,400.

b. Using the accrual basis of accounting, Al's gross income for 2021 is $614,600.

c. Al should use the accrual basis of accounting for reporting his gross income.

a. Under the cash basis of accounting, income is recognized when it is received in cash. In this case, Al received cash of $516,600 for medical services in 2021. However, $37,200 of this amount was for services provided in 2020. Therefore, Al's gross income for 2021 using the cash basis is $516,600 - $37,200 = $479,400.

b. Under the accrual basis of accounting, income is recognized when it is earned, regardless of when the cash is received. In this case, Al earned $516,600 for medical services in 2021, including the $37,200 from 2020. Additionally, Al had accounts receivable of $88,000 at the end of 2021 for services rendered in 2021. Therefore, Al's gross income for 2021 using the accrual basis is $516,600 + $88,000 = $604,600.

c. It is advisable for Al to use the accrual basis of accounting because it provides a more accurate representation of his income by recognizing revenue when it is earned, even if the cash is received later. This method matches revenues with the expenses incurred to generate those revenues, providing a better overall financial picture.
