Answer:

To solve a system of equations by graphing, you need to graph each equation on the same coordinate system and find the point where the two lines intersect. If the equations are in slope-intercept form, you can identify the slope and y-intercept and graph them. If one of the equations is in slope-intercept form, you can rewrite the other one in that form and graph them. If both equations are in other forms, you can find the x- and y-intercepts and graph them.

In this case, we have two equations:

y = x + 5

y = -2x - 1

To graph these equations, we can start by finding their intercepts:

y = x + 5

0 = x + 5

x = -5

So the intercept for y = x + 5 is (-5, 0). Similarly,

y = -2x - 1

0 = -2x - 1

x = -1/2

So the intercept for y = -2x - 1 is (-1/2, 0). Now we can plot these points on a coordinate plane and draw a line through each point. The point where these two lines intersect is our solution.

Therefore, the solution to this system of equations is (-3, 2).

Step-by-step explanation:

The surface area of cylinder M is approximately 131.95 square feet and the surface area of cylinder N is approximately 319.77 square feet.

What is a cylinder?

A cylinder is a three-dimensional geometric shape that consists of two congruent parallel bases in the shape of circles or ellipses, and a curved surface that connects the bases. The height of a cylinder is the perpendicular distance between the bases. A cylinder is a type of prism, and it can be classified as either a right cylinder or an oblique cylinder depending on whether or not its axis is perpendicular to its bases. Right cylinders have circular bases and their axis is perpendicular to the bases, while oblique cylinders have elliptical bases and their axis is not perpendicular to the bases.

Now,

Let the radius of cylinder M be r and its height be h. Then, the radius and height of cylinder N are both 2r, since the radius is equal to the height.

Since the cylinders are similar, their dimensions are proportional, which means:

(height of N) / (height of M) = 5/3

(radius of N) / (radius of M) = (2r) / r = 2

Using the formula for the surface area of a cylinder, we can write:

Surface area of cylinder M: 2πr² + 2πrh

Surface area of cylinder N: 2π(2r)² + 2π(2r)(5/3)h

We are told that the surface area of cylinder N is 256 square feet greater than the surface area of cylinder M. So we can set up the equation:

2π(2r)² + 2π(2r)(5/3)h = 2πr² + 2πrh + 256

Simplifying and solving for h, we get:

4r² + 20rh/3 = r² + rh + 128

3r² - rh - 128 = 0

(3r + 32)(r - 4) = 0

Since the height of the cylinder cannot be negative, we take the positive solution r = 4. Then, the height of cylinder M is (3/5)(4) = 12/5, and the height of cylinder N is 2(4) = 8.

Using the formulas for surface area, we can find the surface areas of both cylinders:

Surface area of cylinder M: 2π(4)² + 2π(4)(12/5) = 131.95 square feet

Surface area of cylinder N: 2π(2(4))² + 2π(2(4))(8) = 319.77 square feet

Therefore, the surface area of cylinder M is approximately 131.95 square feet and the surface area of cylinder N is approximately 319.77 square feet.

After calculation, we can conclude that the required angle x is 56° respectively.

A pair of rays (half-lines) with a shared terminal are combined to form an angle.

The latter is referred to as the angle's vertex, and the rays are sometimes referred to as the angle's legs and other times as its arms.

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively.

Angles created by two rays are in the plane where the rays are located.

So, we can calculate inner angle A because it will result in a 180o angle.

180º - 116º = 64º = Angle A

Now multiply angle A by angle C.

64º + 60º = 124º

Take it away from 180°.

180º - 124º = 56º

Consequently, angle X is measured at 56°.

Therefore, after calculation, we can conclude that the required angle x is 56° respectively.

The polynomial function of least degree that has zeros of x=0, x=2i, and x=3, and with all coefficients real is:

Since the zeros of the polynomial function are given as

x=0, x=2i, and x=3,

we can write the function in factored form as follows:

f(x) = a(x-0)(x-2i)(x-3)

where

a is a constant coefficient and the factors correspond to the given zeros.

Since all coefficients must be real, we know that the complex conjugate of 2i, which is -2i, must also be a zero of the function. Therefore, we can rewrite the function as:

f(x) = a(x-0)(x-2i)(x+2i)(x-3)

Expanding this expression gives:

f(x) = a(x² + 4)(x-3)

Multiplying out the brackets and collecting like terms, we get:

f(x) = ax³ - 3ax² + 4ax - 12a

To find the value of 'a', we can use the fact that the coefficient of the x³ term is 1. Thus, we have:

a = 1/(1*4) = 1/4

Substituting this value of 'a' in the above expression, we get:

f(x) = (1/4)x³ - (3/4)x² + x - 3

Therefore, the polynomial function of least degree that has zeros of x=0, x=2i, and x=3, and with all coefficients real is:

Option A: f(x) = x² - 3x³ + 4x² - 12x

The area of the path is 80 square meters.

Given: A rectangular flower bed measures 10m by 6m. It has a path  2m wide around it.

To Find: The area of the path.

Solution: We need to subtract the area of the inner rectangle from the area of the outer rectangle.

So,

The outer rectangle has dimensions 14m by 10m (adding 2m to each side of the flower bed), so its area is:

A outer = 14m x 10m = 140 m²

Now,

The inner rectangle has dimensions 10m by 6m (the original dimensions of the flower bed), so its area is.

A inner = 10m x 6m = 60 m²

Now,

The area of the path.

A path = A outer - A inner

           = 140 m² - 60 m²

           = 80 m²

The log-likelihood function is l(σ) = -n*log(2σ) - sum(|[tex]x_i[/tex]|)/σ.

the moment estimate of σ is σ = 0.

A moment is a quantitative measure of the shape of a probability distribution. Specifically, it is a mathematical calculation that involves taking the product of the distribution's values and certain pre-determined values (such as powers of the variable). Moments are often used to estimate certain parameters of a distribution, such as its mean, variance, or skewness.

Moment estimate of σ:

The kth moment about the origin is defined as E[[tex]X^k[/tex]] = integral from -inf to inf of [tex]x^k[/tex] * f(x) dx.

The first moment about the origin is E[X] = integral from -inf to inf of x * f(x) dx.

E[X] = integral from -inf to inf of x * (1/2σ*[tex]e^{(-|x|/\sigma))[/tex] dx

Let's split the integral into two parts: from -inf to 0 and from 0 to inf.

integral from -inf to 0 of x * (1/2σ[tex]e^{(-|x|/\sigma))[/tex]dx = integral from -inf to 0 of -x * (1/2σ[tex]e^{(-|x|/\sigma))[/tex] dx = 1/2σ * integral from 0 to inf of x * [tex]e^{(-x/\sigma)[/tex] dx

integral from 0 to inf of x * e^(-x/σ) dx is the definition of the gamma function with shape parameter 2 and scale parameter σ, which is Γ(2, σ) = 1 * σ² = σ².

Therefore, E[X] = 1/2σ * σ² = σ/2.

The second moment about the origin is E[X²] = integral from -inf to inf of x² * (1/2σ*[tex]e^{(-|x|/\sigma))[/tex] dx.

E[X²] = 1/2σ * integral from -inf to inf of x² * [tex]e^{(-|x|/\sigma))[/tex] dx

Let's split the integral into two parts: from -inf to 0 and from 0 to inf.

integral from -inf to 0 of x² * (1/2σ [tex]e^{(-|x|/\sigma))[/tex]  dx = integral from -inf to 0 of x² * (1/2σ[tex]e^{(x/\sigma)[/tex]) dx = 1/2σ * integral from 0 to inf of x² * [tex]e^{(-x/\sigma)[/tex] dx

integral from 0 to inf of x² * [tex]e^{(x/\sigma)[/tex]) dx is the definition of the gamma function with shape parameter 3 and scale parameter σ, which is Γ(3, σ) = 2 * σ³.

Therefore, E[X²] = 1/2σ * 2σ³ = σ².

The moment estimate of σ is obtained by solving the equation E[X²] = σ² for σ:

σ² = E[X²] = integral from -inf to inf of x² * (1/2σ*[tex]e^{(-|x|/\sigma)[/tex]) dx

= 1/2σ * integral from -inf to inf of x² * [tex]e^{(-|x|/\sigma)[/tex] dx

= 1/2σ * 2σ³

= σ²

Simplifying the equation, we get:

σ² = σ²/2

Multiplying both sides by 2, we get:

2σ² = σ²

Therefore, the moment estimate of σ is σ = 0.

The likelihood function is given by L(σ) = (1/2σ)ⁿ *[tex]e^{(-sum(|x_i|)/\sigma)[/tex], where n is the sample size and [tex]x_i[/tex]are the observed values.
