The marginal revenue (in thousands of dollars) from the sale of x gadgets is given by the following function. 2 3 R'(x) = 4x(x²+28,000) a. Find the total revenue function if the revenue from 120 gadgets is $29,222. b. How many gadgets must be sold for a revenue of at least $40,000? a. The total revenue function is R(x) = given that the revenue from 120 gadgets is $29,222. (Round to the nearest integer as needed.)

Answers

Answer 1

a. The total revenue function is R(x) = 2x(x²+28,000)^(1/3) + 29,222 - 240(120)^(1/3).

b. At least 11 gadgets must be sold to generate a revenue of at least $40,000.

a. We are given that the marginal revenue function is R'(x) = 4x(x²+28,000)^(-2/3). We are also given that the revenue from 120 gadgets is $29,222. This means that R(120) = 29,222.

We can find the total revenue function by integrating the marginal revenue function. The integral of R'(x) is R(x) = 2x(x²+28,000)^(1/3) + C. We can find the value of C by substituting R(120) = 29,222 into the equation. This gives us C = 29,222 - 240(120)^(1/3).

Therefore, the total revenue function is R(x) = 2x(x²+28,000)^(1/3) + 29,222 - 240(120)^(1/3).

b. We are given that the revenue must be at least $40,000. We can substitute this value into the total revenue function to find the number of gadgets that must be sold. This gives us 40,000 = 2x(x²+28,000)^(1/3) + 29,222 - 240(120)^(1/3).

Solving for x, we get x = 11.63. This means that at least 11 gadgets must be sold to generate a revenue of at least $40,000.

Revenue function: R(x) = 2x(x²+28,000)^(1/3) + 29,222 - 240(120)^(1/3)

Number of gadgets to generate $40,000 revenue: 11.63

find a value of c so that p(z ≥ c) = 0.55.

Answers

To find a value of c such that P(z ≥ c) = 0.55, we need to use a standard normal distribution table or calculator.From the standard normal distribution table, we find that the z-score corresponding to a right-tailed area of 0.55 is approximately 0.126.

Therefore, we have:

P(z ≥ c) = 0.55

P(z ≤ c) = 1 - P(z ≥ c) = 1 - 0.55 = 0.45

Using the standard normal distribution table, we find that the z-score corresponding to a left-tailed area of 0.45 is approximately -0.126.

So, c = -0.126.

Therefore, the value of c that satisfies P(z ≥ c) = 0.55 is approximately -0.126.

Point P(3, 9) in the coordinate plane is rotated 90 degrees counterclockwise about the origin. What are the coordinates of its image?

Please show all work and not just the answers.

Answers

Answer:

  P'(-9, 3)

Step-by-step explanation:

The transformation for rotation counterclockwise about the origin by some angle α will be ...

  (x, y) ⇒ (x·cos(α) -y·sin(α), x·sin(α) +y·cos(α))

When the angle is α = 90°, this reduces to ...

  (x, y) ⇒ (-y, x)

You have (x, y) = (3, 9), so the image point is P'(-9, 3).

Additional comment

The "work" is applying the right sign and choosing the right coordinate to fill in the values (-y, x). I find it easier to look up the transformations for ±90° and 180°, rather than try to derive them from first principles every time. Your text may have a list:

Un concensario de coches rebaja a 16000 un vehiculo que valia 18300 en que porcentaje lo han rebajado?

Answers

As a car dealer lowers a vehicle that was worth 18300 to 16000 by applying the formula of change in percentage we get that by 12.569 percentage (approximately) the price gets lowered .

The initial price of the car is set at P = 18300 (units)

The price after lowering drom P becomes A= 16000 (units)

Hence the change in price (or value) of the car, that is the price of the car is lowered by, C = (initial price - lowered price) = (P - A) = (18300 - 16000) units = 2300 units.

The formula for calculating percentage change is given as follows,

Change in percentage = [(Change in value)/ ( Initial value) ]*100

⇒Change in percentage = (C/ P)*100

⇒ Change in percentage =( 2300/ 18300)*100 = 12.569% (approximately)

Answer the following questions a Find A b 3 whose eigenvalues are 1 and 4, and whose eigenvectors are *> respectively b Find B whose eigenvalues are 1 and 3

Answers

This gives us the equation -2x + y = 0 and 4x - 3y = 0, which has the solution x = y/2. Therefore, the eigenvector for λ = 3 is v2 = [1; 2].

a) To find matrix A with eigenvalues 1 and 4 and corresponding eigenvectors v1 and v2 respectively, we can use the formula A = PDP^-1 where P is the matrix of eigenvectors and D is the diagonal matrix of eigenvalues.

We know that v1 and v2 are eigenvectors with eigenvalues 1 and 4 respectively, so we can set up the following equations:

Av1 = 1v1 and Av2 = 4v2

Multiplying both sides of each equation by P^-1, we get:

PDv1 = v1 and PDv2 = 4v2

Therefore, P = [v1 v2] and D = [1 0; 0 4], which gives us the matrix A = PDP^-1.

b) To find matrix B with eigenvalues 1 and 3, we can use the same formula A = PDP^-1. However, we don't know the eigenvectors yet. To find them, we can use the characteristic polynomial of B, which is (1-λ)(3-λ) = 0. This gives us eigenvalues λ = 1 and λ = 3.

To find the eigenvectors for λ = 1, we need to solve the equation (B-λI)v = 0, which gives us:

(B-1I)v = 0
[0 1; 1 2][x; y] = [0; 0]

This gives us the equation x + y = 0, so the eigenvector for λ = 1 is v1 = [1; -1].

To find the eigenvectors for λ = 3, we need to solve the equation (B-λI)v = 0, which gives us:

(B-3I)v = 0
[-2 1; 4 -3][x; y] = [0; 0]


Using these eigenvectors and the formula A = PDP^-1, we can find the matrix B = PDP^-1 where P = [v1 v2] and D = [1 0; 0 3].

Graph ​y=4/7x−2​.

Use the line tool and select two points on the line to graph the line.

Answers

Answer:

Therefore, the answer is: The graph of the equation is a straight line passing through the points (0, -2), (7, 2), and (-7, -6).

Step-by-step explanation:

The given equation is y = (4/7)x - 2.

To graph this equation, we need to plot points on a coordinate plane. We can do this by choosing values of x and then finding the corresponding values of y using the equation.

Let's choose some values of x and find the corresponding values of y:

When x = 0, y = (4/7)(0) - 2 = -2

When x = 7, y = (4/7)(7) - 2 = 2

When x = -7, y = (4/7)(-7) - 2 = -6

We now have three points: (0, -2), (7, 2), and (-7, -6). We can plot these points on a coordinate plane and draw a line through them to get the graph of the equation.

The number of seconds after which the ball will hit the ground will be: 0.022 seconds when rounded to the nearest tenth.

How to find the length of time

To find the length of time, the question first requires that we obtain the values for g, Vo and H. We will proceed by using the kinematic equation that makes a relationship between the vertical displacement of an object, its initial velocity, acceleration due to gravity, and time:

y = Vo*t + (1/2)gt^2.

To obtain the value of g, we will use the value of acceleration due to gravity, which is approximately 32 ft/s^2.

Also, to find Vo, we use the initial velocity of the ball, which is 64 ft/s, and for the value of H, we use the initial vertical displacement of the ball, which is 12 ft.

When we substitute all of these figures into the first equaltion, we will have:

-12 = 64t + (1/2)gt^2

Multiplying both sides by 2 and rearranging, we get:

g*t^2 + 128t - 24 = 0

Using the quadratic formula, we get:

t = (-128 ± sqrt(128^2 - 4g(-24)))/(2*g)

t = (-128 ± sqrt(16384 + 384))/64

t = (-128 ± sqrt(16768))/64

t = (-128 ± 129.4)/64

So, t = 1.4/64 or t = -257.4/64

The negative root does not align with the value of time in reality. Therefore, the time it takes for the ball to hit the ground is: t = 1.4/64 = 0.022 seconds.

Answers

Using Pythagorean Theorem, the length of the line segment from (-3, 10) to (4, -1) is 13 units.

Pythagorean theorem describes the relationship between the sides of a right triangle. It states that the square of the hypotenuse is equal to the sum of the squares of the two other side.

c² = a² + b²

Let a = vertical distance between the two points

b = horizontal distance between the two points

c = distance between the two points / length of line segment

Hence, c² = (|y₂ - y₁|)² + (|x₂ - x₁|)².

Substitute the values of x and y and solve for c.

c² = (|y₂ - y₁|)² + (|x₂ - x₁|)²

c² = (|-1 - 10|)² + (|4 - -3|)²

c² = (|-11|)² + (|7|)²

c² = 11² + 7²

c² = 121 + 49

c² = 170

A second-order differential equation with limitations on the solution y = y(x) at two different values of x makes up a second-order boundary-value issue.

What is a differential equation?

Any equation involving the abstract representation y=f(x) including one or more of its derivatives is known as a differential equation.

A function y=f(x) that fulfills the differential equation whenever f and also its derivatives are replaced into the equation is a response to a differential equation.

A system of ordinary differential equations having a solution and derivative values defined at more than one place is referred to as a boundary value problem. A two-point boundary value problem is one where the solution and derivatives are typically provided at just two positions (the boundaries).

A second-order differential equation with limitations on the solution y = y(x) at two different values of x makes up a second-order boundary-value issue. For instance, the boundary value issue y′′ + y = 0 with y(0) = 0 and y (/6) = 4 is quite straightforward.

Yes. A leg of a right triangle can indicate the distance that separates two vertical or horizontal points, and the hypotenuse can represent the distance between two non-vertical or non-horizontal points.

We can use this theorem to calculate the distances between two locations on a coordinate grid. Consider the following example using the points:

Step-by-step explanation:

The angle marked 59 degrees is congruent to angles 1, 3, and 6. The angle marked 59 + angle 11 is 90 degrees because the shape is a rectangle, so 90-59=31. Angle 11 is congruent to angles 2, 4, and 5. Now that we know that the triangle on the left has two angles of 59 degrees and that the angle measures of a triangle add to 180, 59+59=118 and 180-118=62, so angle 9 is 62 degrees. Angles 8 and 9 are vertical angles and therefore are congruent. To find angles 10 and 7, we can use the same method: angles 4 and 5 are both 31 degrees, 31+31=62, so we subtract 62 from 180 to get 118. Angles 7 and 10 are also vertical angles, so they are both 118 degrees. I hope this helps!

Answers

A poster of area 11760 cm2 has blank margins of 10 cm wide on the top and bottom and 6 cm wide on the sides. The dimensions that maximize the printed area are 500 cm x 23.52 cm.

The problem can be solved using the following concept:

Suppose we have a function f(x), then at the maximum/minimum point, it holds:

          f '(x) = 0

In the given problem, let:

q = length of the poster

p = width of the poster

Then,

p x q = 11760

or q = 11760/p

Let f(p,q) be the function of printed area, then:

f(p,q) = (p - 20)(q - 12)

f(p) = (p - 20) (11760/p - 12)

f(p) = -p² + 1000p - 980 x 20

At the maximum point:

f '(p) = 0

-2p + 1000 = 0

p = 500

Substitute p = 500 to get q:

q = 11760/p = 11760/500 = 23.52

Hence, the maximum printed area obtained if the dimensions are 500 cm x 23.52 cm
