You open up a lemonade stand you sell 13 lemonades per hour write an
equation for the situation

Answer:

In this equation, we can start by understanding that "x" has a value of 8, as given in the ordered pair. When multiplied by 5, this leads to "40 - 2y = 30". Next, we can subtract 40 from both sides of the equation. This leads us to a value of "-2y = -10". The next step would be to divide both sides by -2 as a way of isolating "y", which leads us to a final value of "y = 5". The final ordered pair would be (8,5).

The value of b in the equation (x^2 + bx - 2)(x + 3) = x^3 + 6x^2 + 7x - 6 can be determined by comparing the coefficients of the corresponding terms on both sides of the equation. The value of b is 7.

To find the value of b, we expand the left side of the equation (x^2 + bx - 2)(x + 3) using the distributive property. This results in the expression x^3 + 3x^2 + bx^2 + 3bx - 2x - 6.

Comparing this expression with the right side of the equation x^3 + 6x^2 + 7x - 6, we can see that the coefficients of the corresponding terms should be equal. The coefficient of x^2 is 3 in both expressions, the coefficient of x is 7 in both expressions, and the constant term is -6 in both expressions. Therefore, the value of b is 7.

The correct option is a) (x + y) (y + z). Given the output function F in sum-of-minterms form as F = (0, 1, 2, 3, 7), we need to determine the corresponding Boolean expression for the output function.

A 3x8 decoder has three input variables (x, y, z) and eight output variables, where each output variable corresponds to a unique combination of input variables. The output variables are typically represented as minterms.

Let's analyze the given output function F = (0, 1, 2, 3, 7). The minterms represent the outputs that are equal to 1. By observing the minterms, we can deduce the corresponding Boolean expression.

From the minterms, we can see that the output is equal to 1 when x = 0, y = 0, z = 0 or x = 0, y = 0, z = 1 or x = 0, y = 1, z = 0 or x = 0, y = 1, z = 1 or x = 1, y = 1, z = 1.

By simplifying the above conditions, we get (x + y) (y + z), which is the Boolean expression corresponding to the given output function F.

In summary, the correct option is a) (x + y) (y + z).

Therefore , the solution of the given problem of percentage comes out to be the camera's final cost after the markup was $742.90.

In statistics, "a%" refers to a statistic or metric that is expressed as a percentage of 100. The words "pct," "pct," & "pc" are also not widely used. Nonetheless, the symbol "%" is frequently used to represent it. No dimensions exist; the percentage of the entire amount is flat. Percentages are truly integers because their numerator almost always equals 100. To show that a number corresponds to a percent, it must be prefixed with either the percent symbol (%) or the phrase "fraction".

Here,

The camera was lowered by 15% during the sale, making the final cost:

=> $760 - 0.15($760) = $646.00

The price was increased by 15% after the sale, resulting in the following final price:

=> $646.00 + 0.15($646.00) = $742.90

If we round this to the nearest cent, the total comes to $742.90.

As a result, the camera's final cost after the markup was $742.90.

Answer:

E(X) = $1060.

This shows that the expected value of earnings is greater than the cost of entering the race.

Hence, it is worthwhile to enter the race if it costs $1000.

The horse has a probability of 1/20 of coming in first place,

a probability of 1/10 of coming in second place,

and a probability of 1/3 of coming in third place.

Given that the first place pays $4800 to the winner,

second place $3200,

and third place $1500.

we need to find whether it is worth entering the race if it costs $1000.

Let E be the net profit in the race,

which is calculated as the difference between the total earnings and the cost of entering the race,

i.e., E = Total earnings - Cost of entering the race

Given, The probability of the horse coming in first place = 1/20

The probability of the horse coming in second place = 1/10

The probability of the horse coming in third place = 1/3

Now,

Let us calculate the expected value of the earnings, E(X).

E(X) = (1/20) x 4800 + (1/10) x 3200 + (1/3) x 1500

      = 240 + 320 + 500

      = $1060

Therefore, E(X) = $1060.

This shows that the expected value of earnings is greater than the cost of entering the race.

Hence, it is worthwhile to enter the race if it costs $1000.

Answer:

The least possible result is -10.

Step-by-step explanation:

Given the numbers 4, 5 and 6 are to be chosen one of the letters A, B or C.

First of all,

Let A = 4, B = 5 and C = 6

\(A(B-C) = 4 \times (5-6) = 4 \times -1 = -4\)

Let A = 4, B = 6 and C = 5

\(A(B-C) = 4 \times (6-5) = 4 \times 1 = 4\)

Let A = 5, B =4 and C = 6

\(A(B-C) = 5 \times (4-6) = 5 \times -2 = -10\)

Let A = 5, B = 6 and C = 4

\(A(B-C) = 4 \times (6-4) = 4 \times 2 = 8\)

Let A = 6, B = 4 and C = 5

\(A(B-C) = 6 \times (4-5) = 6 \times -1 = -6\)

Let A = 6, B = 5 and C = 4

\(A(B-C) = 6 \times (6-5) = 6 \times 1 = 6\)

Summarizing the above values in the form of a table:

\(\begin{center}\begin{tabular}{ c c c c}A & B & C & A(B-C)\\ 4 & 5 & 6 & -4\\ 4 & 6 & 5 & 4\\ 5 & 4 & 6 & -10\\ 5 & 6 & 4 & 10\\ 6 & 4 & 5 & -6\\ 6 & 5 & 4 & 6\end{tabular}\end{center}\)

The value of a(t) is -1 and b(t) is 55 + \(e^t\)

No, the given equation y' - y = 55 + \(e^t\) is not in the standard form of a first-order linear differential equation.

In the method for solving a first-order linear differential equation, an integrating factor is a function used to transform the equation into a form that can be easily solved.

For an equation in the standard form y' + a(t)y = b(t), the integrating factor is defined as:

μ(t) = e^∫a(t)dt

To solve the equation, you multiply both sides of the equation by the integrating factor μ(t) and then simplify. This multiplication helps to make the left side of the equation integrable and simplifies the process of finding the solution.

To put it in standard form, we need to rewrite it as y' + a(t)y = b(t).

Comparing the given equation with the standard form, we can identify:

a(t) = -1

b(t) = 55 + \(e^t\)

Therefore, The value of a(t) is -1 and b(t) is 55 + \(e^t\)

The orbit type of the Molniya 1-91 satellite is Molniya orbit, characterized by a highly eccentric orbit inclined at an angle of 63.17 degrees to the Earth's equator. The orbital parameters, namely the semi-major axis (a) and the argument of perigee (ω), are required to determine the satellite's position and velocity vectors.

a) The Molniya 1-91 satellite follows a Molniya orbit, which is a type of highly eccentric orbit designed to provide extended dwell time over high latitudes. This orbit is characterized by a high inclination angle of 63.17 degrees with respect to the Earth's equator. Molniya orbits are commonly used for communication satellites that serve polar regions, as they spend a significant portion of their orbit over these areas.

b) To determine the orbital parameters of the Molniya 1-91 satellite, we need to extract the relevant information from the two-line element set. The semi-major axis (a) is not directly provided in the given data. However, we can calculate it using Kepler's third law and the mean motion (n) derived from the second line of the TLE. The argument of perigee (ω) is given as 281.6462 degrees in the TLE. These parameters, along with other orbital elements, are crucial for describing the satellite's orbit.

c) To calculate the position and velocity vectors of the Molniya 1-91 satellite in the geocentric equatorial coordinate frame, we need additional information. The TLE only provides elements related to the orbit's shape and orientation, not the satellite's current position and velocity. Position and velocity vectors can be determined by solving the equations of motion using the orbital parameters and mathematical models of celestial mechanics. However, without up-to-date information on the satellite's time and date, it is not possible to calculate these vectors accurately.

Answer:8/3

Step-by-step explanation: parallel lines have the same slope

To find the radius of a circle with an area of 615.75 km², we can use the formula for the area of a circle:

A = πr²

Given that the area (A) is 615.75 km², we can rearrange the formula to solve for the radius (r):

r = √(A / π)

Substituting the given area into the formula:

r = √(615.75 / π)

Using a calculator, we can approximate the value:

r ≈ √(196.13944)

r ≈ 13.993 km

A circle is characterized by radius, arc, sectors and circumference

The given parameters are:

\(C = 30\pi\) --- the circumference

\(\theta = 225^o\) -- the center angle

The length of the major arc is calculated using:

\(L = \frac{\theta}{360} * C\)

So, we have:

\(L = \frac{225}{360} *30\pi\)

Evaluate

\(L = 18.75\pi\)

Hence, the length of the major arc is \(18.75\pi\)

The circumference is given as:

\(C = 30\pi\)

So, we have:

\(2\pi r = 30\pi\)

Divide through by 2pi

\(r = 15\)

Hence, the radius of the circle is 15

The area of a sector is:

\(A = \frac{\theta}{360} * \pi r^2\)

So, we have:

\(A = \frac{225}{360} * \pi * 15^2\)

There is only one different square root of A.(a) To find the square roots of matrix A = [2 2; 2 2]: Let's consider two matrices B1 and B2: B1 = [1 1; 1 1]; B2 = [-1 -1; -1 -1].

Now, let's check if BB = A for each matrix: B1B1 = [1 1; 1 1] * [1 1; 1 1] = [2 2; 2 2] = A; B2B2 = [-1 -1; -1 -1] * [-1 -1; -1 -1] = [2 2; 2 2] = A. Both B1 and B2 satisfy BB = A, so they are two possible square roots of matrix A. (b) For matrix A = [5 0; 0 9], let's consider a matrix B: B = [√5 0; 0 √9] = [√5 0; 0 3] .We can see that BB = [√5 0; 0 3] * [√5 0; 0 3] = [5 0; 0 9] = A.

Thus, there is only one different square root of A. (c) Not every 2x2 matrix has a square root. For a square root of a matrix to exist, the matrix must be positive definite or positive semidefinite. If the eigenvalues of the matrix are negative or complex, there won't be any real square root. Additionally, if the matrix has zero eigenvalues with multiplicities greater than one, it may not have a unique square root. Therefore, the existence of a square root for a 2x2 matrix depends on its eigenvalues and their properties.
