To calculate the minimum amount of wrapping paper needed to wrap the gift, Naomi would be finding the Surface Area.

The Surface Area of a three-dimensional object is the sum of the areas of all its faces. In this case, the gift is a rectangular prism with dimensions of length 10 inches, height 2 inches, and depth 3 inches.

To wrap the gift, Naomi would need to cover all six faces of the rectangular prism with wrapping paper. The formula for the Surface Area of a rectangular prism is:

Surface Area = 2lw + 2lh + 2wh

where l, h, and w are the length, height, and width of the rectangular prism, respectively.

Substituting the values for the length, height, and depth of the gift, we get:

Surface Area = 2(10 x 2) + 2(10 x 3) + 2(2 x 3)

Surface Area = 20 + 60 + 12

Surface Area = 92 square inches

Therefore, Naomi would need at least 92 square inches of wrapping paper to cover the gift, which is the Surface Area of the rectangular prism.

The characteristic polynomial of A is λ³ - 4λ² - 3λ + 14. The eigenvalues of A are 2, 1, and 7.

According to the rational root theorem, p is a factor of the constant term and q is a factor of the leading coefficient if a polynomial with integer coefficients has a rational root of p/q, where p and q are integers without any shared factors. As the leading coefficient is 1 and the constant term is 14, the only potential rational roots in this situation are 1, 2, 7, and 14.

The characteristic polynomial of a matrix is given as

det(A - λI)

Here, λ is the eigen value.

det (A - λI)

[tex]\left[\begin{array}{ccc}1 - \lambda&0&1\\2&3 -\lambda&-1\\0&6& \lambda\end{array}\right][/tex]

Taking the determinant we have:

det(A - λI) = (1-λ)[(3-λ)(-λ) - (-1)(6)] - 0[2(-λ) - (-1)(0)] + (-1)[2(6) - (3-λ)(0)]

det(A - λI) = (1-λ)(λ² - 3λ - 6) - (-1)(12) = λ³ - 4λ² - 3λ + 14

Hence, the characteristic polynomial of A is λ³ - 4λ² - 3λ + 14.

The eigen values is the solution of the polynomial.

Using the rational roots of polynomial we have:

λ³ - 4λ² - 3λ + 14. factors as (λ-2)(λ-1)(λ-7)

Hence, the eigenvalues of A are 2, 1, and 7.

If we subtract the  tr area 12x6=72m2

216m2–72m2=144m2

Step-by-step explanation:

The equation of the rational function is F(x) = 1/(x-2)(x+1). Thus, the answer is B. F(x) = 1/(x-2)(x+1).

It is a type of function that can be expressed in the form f(x) = p(x) / q(x), where p(x) and q(x) are polynomials and q(x) is not equal to zero. Rational functions are used in various areas of mathematics, including calculus and algebra.

The graph of a rational function is the set of points which satisfy the equation of the rational function.

In this case, the equation of the rational function is F(x) = 1/(x-2)(x+1).

The graph of this function is a line which passes through the points (2, 0) and (-1, 0) and has a vertical asymptote at x = 0.

The graph of a rational function can be determined by finding the zeroes, vertical and horizontal asymptotes, and intercepts of the function.

The zeroes of F(x) = 1/(x-2)(x+1) are x = 2 and x = -1. The vertical asymptote is x = 0 and the horizontal asymptote is y = 0.

The intercepts are (2, 0) and (-1, 0).

The graph of F(x) = 1/(x-2)(x+1) is a line which passes through the points (2, 0) and (-1, 0) and has a vertical asymptote at x = 0.

This is different from the graph of F(x) = 1/X² which is a parabola and from the graph of F(x) = 1(x+2)(x-1) which is two lines intersecting at (2, 0) and (-1, 0).

Therefore, the correct answer is B. F(x) = 1/(x-2)(x+1).

The balance of the account after six years with a single $1856 deposit at an APR of 2.42% that compounds interest quarterly would be $2,177.89.

To calculate the balance of the account after six years, we need to use the formula for compound interest:

A = [tex]P(1 + r/n)^(nt)[/tex]

Where:

A = the final amount

P = the principal amount (initial deposit)

r = the annual interest rate as a decimal

n = the number of times the interest is compounded per year

t = the time the money is invested in years

Using the given values:

P = $1856

r = 2.42% = 0.0242

n = 4 (compounded quarterly)

t = 6

Substituting these values in the formula, we get:

A = [tex]1856(1 + 0.0242/4)^(4*6)[/tex]

A = [tex]1856(1.00605)^24[/tex]

The area of this home plate is equal to 216.5 in².

In order to determine the area of home plate, we would have to apply the law of cosine:

C² = A² + B² - 2(A)(B)cosθ

Where:

A, B, and C represent the length of side or side length of a given triangle.

By substituting the given side lengths and angle into the law of cosine formula, we have the following;

C² = A² + B² - 2(A)(B)cosθ

17² = 12² + 12² - 2(12)(12)cosθ

284 = 144 + 144 - 288cosθ

1 = -288cosθ

cosθ = (-1/288)

θ = 90.199

For the area of home plate, we have:

Area of home plate = Area of rectangle + Area of triangle

Area of home plate = 17(8.5) + 1/2(12)(12)sin90.199

Area of home plate = 144.5 + 72(0.9999940)

Area of home plate = 216.5 in².

The equation of the axis of symmetry of the quadratic function is given by y = -2x² + 8x - 5.

x = 4 is the x-coordinate of the vertex.

x = 0 and x = 4 are the x-coordinates of the x-intercepts.

y = -5 is the y-coordinate of the y-intercept.

A quadratic function has two variables that can be used to model real-world problems. It has a distinct shape of a parabola, which is a symmetrical U-shaped curve.

The coordinates of the vertex of the function can be calculated by taking the derivative of the given equation and setting it equal to 0.

This yields x = 4 as the x-coordinate of the vertex.

Substituting this value in the given equation gives us the y-coordinate of the vertex, which is y = 11.

The coordinates of the x-intercepts of the function can be found by setting y = 0 in the given equation.

This yields x = 0 and x = 4 as the x-coordinates of the x-intercepts. Substituting these values in the given equation gives us the corresponding y-intercepts, which are

y = -5 and y = 0 respectively.

The coordinates of the y-intercept of the function can be found by setting x = 0 in the given equation.

Proportion is a statement that two ratios are equal. A ratio is a comparison of two quantities and is written in the form of a fraction. A proportion can be written in the form of a:b = c:d, where a, b, c, and d are numbers. This means that the ratio of a to b is equal to the ratio of c to d. We can also write a proportion as a fraction, where the numerator is the product of the means (ad) and the denominator is the product of the extremes (bc). Proportions are commonly used in mathematics to solve problems involving ratios and rates.

Here,

Since the floral design is made up of yellow and red hexagonal tiles, we need to determine the proportion of yellow tiles and red tiles in the design. Let's assume that the design consists of x yellow tiles and y red tiles. Each flower in the design consists of 7 hexagonal tiles - 6 yellow tiles and 1 red tile. Therefore, the total number of tiles in the floral design is:

Total number of tiles = 57 flowers x 7 tiles per flower

Total number of tiles = 399 tiles

Since each flower consists of 6 yellow tiles and 1 red tile, the total number of yellow tiles in the design is:

Number of yellow tiles = 6 x Number of flowers

Number of yellow tiles = 6 x 57

Number of yellow tiles = 342

Similarly, the total number of red tiles in the design is:

Number of red tiles = 1 x Number of flowers

Let the side length of the square base be x cm and the height of the box be h cm. Then the volume of the box is given by:

V = x^2 * h = 13,500 cm^3

We want to minimize the amount of material used, which is the surface area of the box. The surface area A is given by:

A = x^2 + 4xh

We can use the volume equation to solve for h in terms of x:

h = 13,500 / x^2

Substituting this into the surface area equation gives:

A = x^2 + 4x(13,500 / x^2) = x^2 + 54,000 / x

To minimize A, we take the derivative with respect to x and set it equal to zero:

dA/dx = 2x - 54,000 / x^2 = 0

Solving for x, we get:

x^3 = 27,000

x = 30

Substituting this back into the volume equation gives:

h = 13,500 / (30^2) = 15

Therefore, the dimensions of the box that minimize the amount of material used are 30 cm by 30 cm by 15 cm.

Step-by-step explanation:

We can start by solving the second equation for one of the variables. Let's solve for y:

3x + 3y = 6

3y = 6 - 3x

y = 2 - x

Now we can substitute this expression for y into the first equation:

9x - 19y = 74

9x - 19(2 - x) = 74 (substituting y = 2 - x)

9x - 38 + 19x = 74

28x = 112

x = 4

Now we can use this value to find y:

y = 2 - x

y = 2 - 4

y = -2

Therefore, the solution to the system of equations is x = 4 and y = -2.
