For a andrea's record label released her new album, the simplified inequality of absolute value inequality in terms of t is equals to the t ≥ 10. The graph which represents the inequlity is option(b).

Andrea's record label released her new album. Now, she wants to know the sales of at least $20,000 per week. The equation where sales will be at least 20,000 amount is written as 20,000≤ 1000(-2|t - 15| + 30). We have to solve this inequality. Now, the inequality is written as 20,000 ≤ 1000(-2|t - 15| + 30)

dividing by 1000 both sides, [tex] \frac{20,000 }{1000} ≤ (-2|t - 15| + 30) [/tex]

=> 20 ≤ (-2|t - 15| + 30)

Substracts 20 from both sides

=> 20- 30 ≤ -2|t - 15| + 30 - 30

=> -10 ≤ -2|t - 15|

dividing by (-2) by both sides in above equation,

=> 5 ≤ | t - 15 |

=> -(t - 15) ≤ 5 ≤ (t - 15)

=> - t + 15 ≤ 5 ≤ t - 15

=> - t + 15≤ 5 or 5 ≤ t - 15

=> -t ≤ - 10 or 15 ≤ t

The value of the double integral of x² over the region bounded by the ellipse 9x² + 4y² = 36 using the given transformation is π/4.

First, let's define the given transformation. We are given that x=2u and y=3v, which means that we are transforming our original x-y plane into a u-v plane.

We know that the region is bounded by the ellipse 9x² + 4y² = 36. Substituting the given transformations into this equation, we get:

9(2u)² + 4(3v)² = 36 36u² + 36v² = 36 u² + v² = 1

Now, we can use the transformation formula to evaluate the double integral of x² over this region. The transformation formula tells us that:

∬R f(x,y) dA = ∬S f(u,v) |J| dA

where R is the region in the x-y plane, S is the region in the u-v plane, f(x,y) is the integrand in the x-y plane, f(u,v) is the integrand in the u-v plane, |J| is the Jacobian determinant of the transformation (which we will find shortly), and dA is the area element in the respective planes.

In our case, f(x,y) = x² and f(u,v) = (2u)² = 4u². The area element dA in the x-y plane is dx dy, while in the u-v plane it is |6| du dv (since |J| = |d(x,y)/d(u,v)| = |6|). Thus, our integral becomes:

∬R x² dA = ∬S (4u²) (|6|) du dv

Integrating this expression over the limits -1 to 1 for both u and v, we get:

∬S (4u²) (|6|) du dv = 48 ∫∫S u² du dv

where S is the unit circle in the u-v plane. To evaluate the double integral ∫∫S u² du dv, we can use polar coordinates, where u = r cos θ and v = r sin θ. Then, the integral becomes:

[tex]\int _{\theta =0} ^{2\pi} \int_{r=0} ^{ 1}[/tex] (r² cos² θ) r dr dθ

Evaluating this integral using standard techniques, we get:

[tex]\int _{\theta =0} ^{2\pi} \int_{r=0} ^{ 1}[/tex] (r³ cos² θ) dr dθ

[tex]\int _{\theta =0} ^{2\pi} \int_{r=0} ^{ 1}[/tex] (cos² θ)/4 dθ

Simplifying this expression, we get:

[tex]\int _{\theta =0} ^{2\pi}[/tex] (cos² θ)/4 dθ = ∫θ=0 to 2π (1 + cos 2θ)/8 dθ

Using the fact that ∫ cos 2θ dθ = 0 and ∫ dθ = 2π, we get:

[tex]\int _{\theta =0} ^{2\pi}[/tex] (cos² θ)/4 dθ = (1/8) [tex]\int _{\theta =0} ^{2\pi}[/tex]dθ + (1/8) [tex]\int _{\theta =0} ^{2\pi}[/tex] cos 2θ dθ

Express the rational function 2x⁴/(x² - 2x) as a sum or difference of two simpler rational expressions:

2x⁴/(x² - 2x) = 2x² + 4x + 8 + 16/(x - 2).

The given expression is,

2x⁴/(x² - 2x)

simplifying we get,

= 2x⁴/x(x - 2) [taking 'x' as common from both the term of denominator]

= 2x³/(x - 2) [Cancelling the same value from numerator and denominator]

Now if we divide '2x³' by (x-2) we get

Quotient = 2x² + 4x + 8

Remainder = 16

So from the division algorithm we know that,

Dividend = Divisor*Quotient + Remainder

Here Dividend = 2x³ and Divisor = x - 2

So, 2x³ = (x - 2)*(2x² + 4x + 8 ) + 16

Now, 2x⁴/(x² - 2x)

= 2x³/(x - 2)

= ((x - 2)*(2x² + 4x + 8 ) + 16)/(x - 2)

= ((x - 2)*(2x² + 4x + 8) )/(x - 2) + 16/(x - 2)

= 2x² + 4x + 8 + 16/(x - 2).

So the simpler rational functions are: (2x² + 4x + 8) and 16/(x - 2).

Answer:

40 inches.

Step-by-step explanation:

If you want to measure how much fence you need to enclose a rectangle, you have to add up the lengths of all its sides. That's called the perimeter. The easiest way to find it is to use this handy-dandy formula:

Perimeter = 2 (length + width) units

where length and width are how long the rectangle's sides are.

For example, let's say you have a rectangle that is 12 inches long and 8 inches wide. To find its perimeter, you just plug in those numbers into the formula:

Perimeter = 2 (12 + 8) inches

Perimeter = 2 (20) inches

Perimeter = 40 inches

Ta-da! The perimeter of the rectangle is 40 inches.

Approximately 9.5% of the racers did not complete the marathon.

The total of those who quit and those who were disqualified represents the number of runners who did not finish the marathon

Number who did not complete = 12 + 8 = 20

To find the percentage of racers who did not complete the marathon, we need to divide this number by the total number of racers who started the marathon (210) and multiply by 100

Percentage who did not complete is

= (20 / 210) x 100

= 9.523%

Rounding this to the nearest tenth of a percent gives us a final answer of 9.5%. Therefore, approximately 9.5% of the racers did not complete the marathon.

The volume of the solid is [tex]\frac{32}{3}[/tex] cubic units.

To find the volume of the solid, we need to integrate the area of each cross section taken perpendicular to the y-axis over the range of y-values that the ellipse covers.

the height of each cross section will be equal to the y-coordinate of the ellipse at that point, since the triangles are isosceles and right-angled. The base of each cross section will be twice the height, since the triangles are isosceles, and the hypotenuse will lie in the ellipse.

So, for a given y-value, the area of the cross section will be:

[tex]A(y) = \frac{1}{2} \cdot 2y \cdot y = y^2[/tex]

To find the limits of integration for y, we need to find the y-coordinates of the points where the ellipse intersects the y-axis. We can do this by setting x = 0 in the equation of the ellipse:

[tex]4x^2 + 9y^2 = 36\\9y^2 = 36\\y^2 = 4\\y = \pm 2[/tex]

So, the limits of integration for y are -2 and 2.

The volume of the solid can now be found by integrating the area of the cross sections over the range of y-values:

The answer is that an eight-ounce glass of apple juice contains 54.5 milligrams of vitamin C, and an eight-ounce glass of orange juice contains 67 milligrams of vitamin C.



Let's use algebra to solve this problem.

First, let's define two variables:

- Let's call the amount of vitamin C in one eight-ounce glass of apple juice "a".
- Let's call the amount of vitamin C in one eight-ounce glass of orange juice "o".

Using this notation, we can translate the information given in the problem into two equations:

- Equation 1: a + o = 181.5 (since one glass of apple juice and one glass of orange juice contain a total of 181.5 milligrams of vitamin C)
- Equation 2: 2a + 4o = 538.6 (since two glasses of apple juice and four glasses of orange juice contain a total of 538.6 milligrams of vitamin C)

Now we can solve this system of equations to find the values of "a" and "o".

One way to do this is to use the first equation to express one variable in terms of the other. For example, we could solve for "a" by subtracting "o" from both sides of Equation 1:

a = 181.5 - o

Then we could substitute this expression for "a" into Equation 2, and solve for "o":

2(181.5 - o) + 4o = 538.6

363 - 2o + 4o = 538.6

2o = 175.6

o = 87.8

Now that we know that one eight-ounce glass of orange juice contains 87.8 milligrams of vitamin C, we can use Equation 1 to find the amount of vitamin C in one glass of apple juice:

a + 87.8 = 181.5

a = 93.7

Therefore, an eight-ounce glass of apple juice contains 93.7 milligrams of vitamin C, and an eight-ounce glass of orange juice contains 87.8 milligrams of vitamin C.

The function F = ∇f is obtained by taking the partial derivatives is (3 + 2xy) i + (x² − 3y²) j where C is a constant. The line integral ∫ F. Dr is evaluated by plugging in the parametric equations of the given curve C into the function F is 38.36.

To find a function F = ∇f, we need to find the gradient of f, which is a vector-valued function that has F as its gradient. Therefore, we need to find the partial derivatives of f with respect to x and y.

∂f/∂x = 3 + 2xy

∂f/∂y = x² − 3y²

Integrating the first equation with respect to x, we get

f(x, y) = 3x + x²y + g(y)

where g(y) is an arbitrary function of y that depends only on y.

Taking the partial derivative of f with respect to y, we get:

∂f/∂y = x² + g'(y)

Comparing this to the second equation, we get

g'(y) = −3y²

Integrating g'(y) with respect to y, we get

g(y) = −y³ + C

where C is a constant of integration.

Substituting this into our expression for f(x, y), we get:

f(x, y) = 3x + x²y − y³ + C

Therefore, F = ∇f is given by

F = ∇f = (3 + 2xy) i + (x² − 3y²) j

To evaluate the line integral ∫ F·dr, we need to first parameterize the curve C using t as the parameter.

[tex]r(t) = e^t sin(t) i + e^t cos(t)[/tex] j, 0 ≤ t ≤ π

The velocity vector of the curve is given by

r'(t) = [tex]e^t[/tex] (cos(t) i − sin(t) j)

Using the formula for the line integral, we get

∫ F·dr = ∫ F(r(t)) · r'(t) dt

Substituting in the expressions for F and r'(t), we get

∫ [(3 + 2xy) i + (x² − 3y²) j] · [[tex]e^t[/tex] (cos(t) i − sin(t) j)] dt

=[tex]\int\limits [3e^t cos(t) + 2e^{2t} sin(t) cos(t)] dt - \int\limits [3e^{2t} sin^{2t} - e^{2t} cos^{2t}] dt[/tex]

Evaluating these integrals, we get:

The bus company will have maximum revenue when there are 120 people on the charter bus.

What is the quadratic equation?

The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

The revenue R for the bus company as a function of n can be expressed as follows:

For n < 80: R = 0 (since the company requires at least 80 people to operate a charter bus)

For n a 80: R = n(8 - 0.05(n - 80))

Simplifying the expression:

R = 8n - 0.05n² + 4n

R = -0.05n² + 12n

Therefore, the revenue of the bus company is a quadratic function of the number of people, with a negative coefficient for the quadratic term, indicating that the function has a maximum value.

This maximum value occurs at the vertex of the parabola, which can be found using the formula -b/2a, where a = -0.05 and b = 12:

n = -b/2a = -12/(2*(-0.05)) = 120

Thus, the bus company will have maximum revenue when there are 120 people on the charter bus.

The probability that at least one of the cards that you pick is a heart is 7/16.

The possible outcomes are given below as:

(S,S), (S,H), (S,D), (S,C),

(H,S), (H,H), (H,D), (H,C),

(D,S), (D,H), (D,D), (D,C),

(C,S), (C,H), (C,D), (C,C)

In all, 16 possibilities exist.

The probability of getting a matching pair is 4/16 or 1/4.

Essentially, out of the 16 options laid out above, there will be four pairs the same: (S,S), (H,H), (D,D), and (C,C).

The chances that at least one heart is drawn can be calculated through this method:

Subtracting the chance that no hearts are drawn from 1 will tell us what we need to know

We find the odds of selecting no heart cards twice and multiply them: For both piles, it's 3/4 * 3/4 = 9/16.

Part D: Then we subtract that number from 1 to get the final answer: 7/16.

To order the sides of ΔABC from shortest to largest, we need to measure each side and compare them. The shortest side of the triangle will be the one with the smallest length, while the largest side will be the one with the greatest length. The middle side will be the one that is neither the shortest nor the largest.

To measure the sides of ΔABC, we can use a ruler or a measuring tape. Once we have measured each side, we can compare them to determine which is the shortest, which is the middle, and which is the largest.

For example, if the lengths of the sides of ΔABC are 3 cm, 4 cm, and 5 cm, then the shortest side is 3 cm, the middle side is 4 cm, and the largest side is 5 cm.

In summary, to order the sides of ΔABC from shortest to largest, we need to measure each side and compare them. The side with the smallest length will be the shortest side, the side with the greatest length will be the largest side, and the remaining side will be the middle side.

Answer: $2.09

Step-by-step explanation: 0.76/2=0.38 so each pound of apples costs $0.38. Since we want to find how much 5.5 pounds cost, we multiply by 5.5. $0.38*5.5=$2.09 so our answer is $2.09

When using non-self supporting ladders, it is essential to ensure they are positioned at an appropriate angle to provide the necessary stability and safety for the user.

The angle at which the ladder is placed is critical because it determines the distance between the base of the ladder and the wall or surface it is resting against, In general, non-self supporting ladders must be positioned at an angle where the horizontal distance is no less than 1/4 of the ladder's working length.

For example, if you are using a 12-foot ladder, the base of the ladder should be positioned 3 feet away from the wall or surface it is leaning against. This ensures that the ladder is stable and will not slip or tip over during use.

The angle of the ladder is also important because it affects the amount of force and pressure exerted on the ladder and the surface it is resting against. If the ladder is placed at too steep of an angle, the weight of the user can cause the ladder to slide or fall backward. Conversely, if the ladder is placed at too shallow of an angle, the weight of the user can cause the ladder to slide or fall forward.

Therefore, it is crucial to position non-self supporting ladders at an appropriate angle to ensure the safety of the user. Always follow the manufacturer's guidelines and safety instructions when using ladders and avoid taking unnecessary risks. Remember to take your time and stay focused on the task at hand to avoid accidents and injuries.

The vertical height of pyramid is 3.6 cm.

Given that,

The base area of the pyramid is 5 cm², or 25 cm²

The formula V = (1/3) base area height can be used to determine the volume of a pyramid,

Where the solid's total height equals the sum of the cuboid and pyramid heights. T.

Let's abbreviate the pyramid's vertical height "h"

The height of the cuboid would thus be,

=  (1000g - 104.17gh)/(200g) or (1000g - (8g (25 h)/3))/(8 (5)²).

Therefore,

V = (1/3) 25cm2 h + 5cm (1000g - 104.17gh)/(8g/cm³ * (5cm)²)

It represents the solid's overall volume.

Given that we are aware that the solid has a mass of 1 kg (1000 g),

Adjust density times volume to equal mass:

8g/cm³ * V = 1000g

When we solve for V,

⇒V = 125cm3.

Solve for h by adding V to the previous equation and getting the following result:

h = (3(125cm³ 8g/cm³ - 5cm 1000g)/(25cm² 8g/cm³)

which can be expressed as h = 3.6 cm.

As a result, the pyramid has a 3.6 cm vertical height.
