the evaluated double integral is approximately 14.25.

To evaluate the given double integral, we need to first understand the problem properly. We have the function f(x, y) = y + xy, and the region R is described by the inequalities: 0 < x < y^2, and 1 < y < 2.

Now we can set up the double integral:

∬(y + xy) dA over the region R.

Since we are given that 0 < x < y^2 and 1 < y < 2, we can set up the integral using the given limits of integration:

∫(from y = 1 to 2) ∫(from x = 0 to y^2) (y + xy) dx dy.

Now, we can start by integrating the inner integral with respect to x:

∫(from y = 1 to 2) [(yx + (1/2)x^2*y) evaluated from x = 0 to x = y^2] dy.

After evaluating the inner integral, we have:

∫(from y = 1 to 2) (y^3 + (1/2)(y^2)^2*y) dy.

Now, we can integrate the outer integral with respect to y:

[((1/4)y^4 + (1/6)y^6) evaluated from y = 1 to y = 2].

After evaluating the outer integral, we get:

[(1/4)(2^4) + (1/6)(2^6)] - [(1/4)(1^4) + (1/6)(1^6)].

Calculating the final result:

(4 + 10.6667) - (0.25 + 0.1667) = 14.6667 - 0.4167 ≈ 14.25.

The median means that as many as friends have less than A. 1. 5 pets as those that have more than A. 1. 5 pets.

The median is a measure of central tendency in statistics that represents the middle value of a dataset when it is ordered from smallest to largest. The median is often used as a more robust measure of central tendency than the mean, because it is less affected by extreme values in the dataset.

From the box plot, the data set of friends with pets would be:

0, 0, 0, 1, 1, 1, 1, 1, 1, 1, 2, ,2 ,2, 2, 2, 2, 3, 4, 4, 7.

The median here is:

Answer:

Based on the given graph, we can see that the bars representing salaries above $175,000 span a total of 7 employee salaries. Since each bar spans a width of $50,000, we can estimate that the total number of employees making at least $175,000 is approximately 7 multiplied by 50,000 divided by 10,000, which equals 35%. Therefore, the owner can justify the claim that on average an employee makes at least $175,000 by stating that approximately 35% of the current employees already make at least that amount. However, it's important to note that this calculation is based on estimates and assumptions and should not be used as a definitive answer.

m∠f to the nearest degree is 83°.

The Law of Cosines is used to find an angle when all triangle sides are known.

f² = d² +e² -2de cos(F)

To find angle ∠F, we need to find the value of cos(∠F), which we can do by rearranging the Law of Cosines as follows:

cos(F) = (d² +e² -f²) / (2de)

cos(F) = (20² + 25² - 30²) / (2 × 20 × 25)

cos(F) = (400 + 625 - 900) / (1000)

cos(F) = 125/1000

∠F = arccos(1/8)

∠F = 82.8°

The side length of the base of the rectangular prism is approximately 1.2 cm.

The top, bottom, and lateral faces of a rectangular prism are all rectangles, and all the pairings of the opposing faces are congruent. A rectangular prism is a three-dimensional structure with six faces.

Let's denote the side length of the base of the rectangular prism as "x" cm.

We know that the volume of a rectangular prism is given by the formula:

Volume = Base Area x Height

In this case, the base is a square, so its area is given by:

Base Area = x²

We are given that the volume is 24.768 cm³ and the height is 17.2 cm.

Therefore, we can write the equation:

24.768 = x² * 17.2

To find the value of x, we can rearrange the equation:

x² = 24.768 / 17.2

x² = 1.4376

Taking the square root of both sides, we get:

x = √1.4376

x ≈ 1.2

Therefore, the side length of the base of the rectangular prism is approximately 1.2 cm.

Answer:

x = -9

Step-by-step explanation:

As this is an absolute value function, the line of symmetry is the x-value of the maximum/minimum point. An absolute value function can be denoted as y = |x - h| + k, where (h, k) is the maximum/minimum point. We only need the x-value of the maximum/minimum point, so we only have to look at "h". Now, we can use y = |x - h| + k and turn it into g(x):

y = |x - h| + k

g(x) = |x - -9| + -11   --> this means h = -9, and the line of symmetry is at x = -9

g(x) = |x + 9| - 11

According to given question Mike has 25 candies in the beginning.

Let's assume that Mike had "x" candies in the beginning.

After giving 15 candies to his friend, he would have had (x - 15) candies left.

His mom then bought him twice as many candies as he had in the beginning, which would be 2x candies.

So, the total number of candies Mike has now is (x - 15) + 2x = 60.

Combining like terms, we get 3x - 15 = 60.

To find the temperature at 6pm, we need to start with the temperature at 9am and then add or subtract the changes in temperature that occurred during the day.

We know that the temperature at 9am was -1.9°F. Between 9am and noon, the temperature rose 11.3°F, so at noon the temperature was:

-1.9 + 11.3 = 9.4°F

Between noon and 3pm, the temperature dropped 7.9°F, so at 3pm the temperature was:

9.4 - 7.9 = 1.5°F

Between 3pm and 6pm, the temperature dropped 12.7°F, so at 6pm the temperature was:

1.5 - 12.7 = -11.2°F

Therefore, the temperature at 6pm was -11.2°F.

A: P(t) [tex]= $567,000 * (1 + 0.126)^t[/tex]

B: [tex]567,000 * (1 + 0.126)^2 = $671,448.14[/tex]

A: To model the price of the house over time, we can use the exponential formula: P(t) = P₀ * (1 + r)^t, where P₀ is the initial price, r is the rate of appreciation, and t is the time in years.

In this case, the initial price (P₀) of the house is $567,000 and the rate of appreciation (r) is 12.6% expressed as a decimal, which is 0.126. Therefore, the exponential formula to model the price of the house over time would be: P(t) = 567,000 * (1 + 0.126)^t.

B: To find the price of the house in 2022, we substitute t = 2022 - 2020 = 2 into the exponential formula.

P(2) = 567,000 * (1 + 0.126)^2

P(2) = 567,000 * (1.126)^2

P(2) ≈ 567,000 * 1.268

P(2) ≈ $719,976.00

Prerequisites for the MVT are not met due to the discontinuity and non-differentiability of f(x) at x = 0 within the interval [-1, 1].

Let's first understand the Mean Value Theorem (MVT). The MVT states that if a function is continuous on the closed interval [a, b] and differentiable on the open interval (a, b), then there exists a number c in (a, b) such that:

f'(c) = (f(b) - f(a)) / (b - a)

Now, consider the function f(x) = 1/x^2. This function is continuous and differentiable for all x ≠ 0. However, in the interval [-1, 1], the function is not continuous nor differentiable at x = 0. Therefore, the Mean Value Theorem does not apply to this interval.

Since the MVT does not apply, we cannot say there exists a c in the interval (-1, 1) such that f'(c) = (f(1) - f(-1)) / (1 - (-1)). This is because the prerequisites for the MVT are not met due to the discontinuity and non-differentiability of f(x) at x = 0 within the interval [-1, 1].

Philip should receive $68.50 in quarterly dividends and the annual yield on this stock is about 2.81%.

To calculate the quarterly dividend that Philip need to acquire, we need to first calculate the quarterly dividend per share:

Quarterly dividend in step with share = Annual dividend per percentage / 4

In this situation, the once a year dividend in line with proportion is $2.74, so the quarterly dividend per proportion is:

Quarterly dividend per proportion = $2.74 / 4 = $0.685

For the reason that Philip owns 100 shares, his quarterly dividend should be:

Quarterly dividend = Quarterly dividend per share * number of stocks

Quarterly dividend = $0.685 * 100 = $68.50

Therefore, Philip should receive $68.50 in quarterly dividends.

To calculate the once a year yield on this inventory, we want to divide the yearly dividend in line with proportion by the present day stock price, after which multiply by way of 100 to specific the result as a percentage:

Annual yield = (Annual dividend per share / inventory price) * 100

In this case, the annual dividend per percentage is $2.74, and the inventory charge is $97.55. Plugging those values into the components, we get:

Annual yield = ($2.74 / $97.55) * 100

The rate can be expressed as "3 players per sport"

A rate is a ratio that compares two quantities with different units. In this case, we have 30 players and 10 sports. To express this as a rate, we want to compare the number of players to the number of sports. We can write this as:

30 players / 10 sports

To simplify this ratio, we can divide both the numerator (30 players) and denominator (10 sports) by the same factor to get an equivalent ratio. In this case, we can divide both by 10:

(30 players / 10) / (10 sports / 10)

This simplifies to:

3 players / 1 sport

So the rate can be expressed as "3 players per sport" or "3:1" (read as "three to one"). This means that for every one sport, there are three players.

Alternatively, we can express the rate as a fraction or decimal by dividing the number of players by the number of sports:

30 players / 10 sports = 3 players/sport = 3/1 = 3 or 3.0 (as a decimal)

Answer: ∠b = 105°

Step-by-step explanation:

     We know that a straight line is equal to 180 degrees. We will create an equation and solve for ∠b.

180° = ∠b + 75°

∠b = 180° - 75°

∠b = 105°

1-To get from one corner of his yard to another, Jason travels 4 units down and then 6 units right. Starting from the origin, his starting point is (0,0). From there, he moves 4 units down to the point (0,-4), and then 6 units right to reach his endpoint, which is at (6,-4).

2-The rectangle has two sides of length 4 and two sides of length 6. The perimeter is the sum of the lengths of all sides, so it is equal to 2(4) + 2(6) = 8 + 12 = 20 units.

3-The coordinates of points Y, X, and Z are not given, so we cannot calculate the lengths directly. However, we know that the sides of a rectangle are perpendicular, so we can use the Pythagorean theorem to find the lengths. Let Y be the origin (0,0), and let X be the point (0, -4). Then YX has length 4 units. Similarly, let Z be the point (6, 0), so YZ has length 6 units.

4.To find the area of a rectangle, we can multiply the lengths of its sides. From problem 3, we know that the lengths of the sides are 4 and 6 units, so the area is 4 x 6 = 24 square units.

5. The sides AB and AC form a right angle.

To determine which sides of the triangle form a right angle, we need to find the slope of each side. The slope of AB is (3-8)/(6-3) = -5/3, and the slope of AC is (3-3)/(6-3) = 0. Since the product of the slopes of two perpendicular lines is -1, we can see that AB is perpendicular to AC. Therefore, sides AB and AC form a right angle.

6. Tyler walks 9 blocks in all.

To find the distance Tyler walks, we need to calculate the length of sides AB and AC. Using the distance formula, we can find that the length of AB is sqrt[(6-3)² + (3-8)²] =√[(34) units, and the length of AC is 3 units. Therefore, Tyler walks 3 + √[34 units along the two sides that form the right angle. This is approximately 9.4 blocks, so he walks 9 blocks in all.

Dina can reach a maximum kinetic energy of 2450 Joules when she skis to the bottom of the slope.

Potential energy (PE) = m x g x h

where m = mass, g = acceleration due to gravity, and h = height

Here, Dina's mass (m) = 50 kg, height (h) = 5 m, and acceleration due to gravity (g) = 9.8 m/s².

So, PE = 50 x 9.8 x 5

PE = 2450 Joules

When Dina skis down the slope, all of her potential energy will be converted into kinetic energy (KE) at the bottom of the slope, neglecting any losses due to friction and air resistance.

Thus, the maximum kinetic energy (KE) Dina can reach at the bottom of the slope is also 2450 Joules.

The maximum kinetic energy she can reach when she skis to the bottom of the slope is 2452 joules

To find the maximum kinetic energy that Dina can reach when she skis to the bottom of the slope, we need to use the principle of conservation of energy, which states that the total energy of a system remains constant.

At the top of the slope, Dina has potential energy due to her position relative to the ground. This potential energy is given by:

PE = m × g × h

where m is Dina's mass (50 kg), g is the acceleration due to gravity (9.8 m/s^2), and h is the height of the slope (5 m).

PE = 50 kg × 9.8 m/s^2 × 5 m = 2450 J

When Dina skis to the bottom of the slope, all of her potential energy is converted into kinetic energy, which is given by:

KE = 1/2 × m × v^2

where v is her velocity at the bottom of the slope.

To find the maximum velocity, we can use the fact that the total energy of the system remains constant:

PE = KE

2450 J = 1/2 × 50 kg × v^2

v^2 = 98 m^2/s^2

v = sqrt(98) = 9.90 m/s

Finally, we can substitute this velocity into the kinetic energy equation to find the maximum kinetic energy that Dina can reach:

KE = 1/2 × 50 kg × (9.90 m/s)^2 = 2452 J

Therefore, Dina can reach a maximum kinetic energy of 2452 Joules when she skis to the bottom of the slope.

To determine whether a critical point is a relative minimum or maximum using concavity, we need to examine the second derivative of the function at the critical point.

If the second derivative is positive, then the function is concave up, meaning it is shaped like a bowl opening upwards. At a critical point where the first derivative is zero, this indicates a relative minimum, as the function is increasing on either side of the critical point.

On the other hand, if the second derivative is negative, then the function is concave down, meaning it is shaped like a bowl opening downwards. At a critical point where the first derivative is zero, this indicates a relative maximum, as the function is decreasing on either side of the critical point.

If the second derivative is zero, then the test is inconclusive and further analysis is needed, such as examining higher order derivatives or using other methods such as the first derivative test.

Use ratios of corresponding sides to get:

Simplify and solve for y:

The solution to the differential equation is f(a) = 1/√(12a⁴/125 - 769/5000).

To find f(a), we need to solve the differential equation:

dy/dx = 24yx³

Separating variables, we get:

dy/y³ = 24x³ dx

Integrating both sides, we get:

-1/(2y²) = 6x⁴ + C

where C is the constant of integration.

To find the value of C, we use the fact that the y-intercept of the curve y = f(2) is 5. This means that when x = 2, y = 5. Substituting these values into the equation above, we get:

-1/(2(5)²) = 6(2)⁴ + C

Simplifying and solving for C, we get:

C = -1/(2(5)²) - 6(2)⁴

C = -769/125

So the solution to the differential equation is:

-1/(2y²) = 6x⁴ - 769/125

Solving for y, we get:

y = 1/√(12x⁴/125 - 769/5000)

Therefore, f(a) = 1/√(12a⁴/125 - 769/5000).
