Answer:

Harry sold 8 2/5 boxes of candy

Step-by-step explanation:

Last month, Regan and Harry sold candy to raise money for their debate team.

We are told:

Harry sold 2 times and much candy as Regan did.

Regan sold 4 1/5 boxes of candy,

The number of boxes of candy that Harry sold =

4 1/5 boxes of candy × 2

= 21/5 × 2

= 42/5

= 8 2/5 boxes of candy.

Therefore, Harry sold 8 2/5 boxes of candy

The measure of arc mAD is 119°.

In geometry, an arc is a portion of a curve or a circle. It is defined as a connected portion of the circumference of a circle, which is characterized by its central angle, length, and location. The length of an arc is proportional to the measure of its central angle, and the measure of the arc is given in degrees or radians.

The circumference of a circle is the distance around the circle, and it is equal to 2πr, where r is the radius of the circle. An arc of a circle is a part of the circumference, and its length can be calculated using the formula:

Arc length = (central angle/360 degrees) * 2πr

where the central angle is measured in degrees, and r is the radius of the circle.

Since chord AB, BC, CD, and DA form a quadrilateral, we know that the opposite angles of the quadrilateral add up to 180°. Therefore, ∠ABC = 180 - ∠DAB = 180 - 75 = 105°, and ∠BCD = 180 - ∠ADC = 180 - 102 = 78°.

Next, we can use the inscribed angle theorem to find the measure of arc AD. We know that ∠ACD is half the measure of arc CD, so arc CD = 2 * ∠ACD = 62°. Therefore, ∠ACD = 31°.

Similarly, ∠ABD is half the measure of arc AB, so arc AB = 2 * ∠ABD. We can find angle ABD by subtracting angle DAB from ∠ABC: ∠ABD = ∠ABC - DAB = 105 - 75 = 30°. Therefore, arc AB = 2 * 30 = 60°

Since the sum of the measures of angles ABD, ACD, and the central angle arc AD is 180°, we have:

∠ ABD + ∠ ACD + arc AD = 180

Substituting the values we found, we get:

30 + 31 + arc AD = 180

Solving for arc AD, we get:

arc AD = 180 - 30 - 31 = 119°

Therefore, the measure of arc mAD is 119°.

Answer:

x=3 or (3,0) y=0

Step-by-step explanation:

The y-intercept is the point where x=0, so we see it is 'b', which equals -9, or the point (0,-9) The x-intercept is the point where y=0, so we see it is x=3, or the point (3,0).

The correct solution of the linear differential equation dy/dx = xy^2, obtained by separating the variables, is y = -1/(c - x^2), where c is a constant.

To solve the given linear differential equation, we can separate the variables by writing it as dy/y^2 = xdx. Integrating both sides, we get ∫(1/y^2)dy = ∫xdx.

The integral of 1/y^2 with respect to y is -1/y, and the integral of x with respect to x is (1/2)x^2. Applying the antiderivatives, we have -1/y = (1/2)x^2 + c, where c is the constant of integration.

To isolate y, we can take the reciprocal of both sides, resulting in y = -1/(c - x^2), where c represents the constant of integration.

Therefore, the correct solution of the linear differential equation dy/dx = xy^2, obtained by separating the variables, is y = -1/(c - x^2), where c is a constant.

The MP curve initially rises to its maximum value because of the specialized nature of the fixed capital, where each additional worker's productivity rises due to the marginal product of the fixed capital.

Production Function: q = f(L,K) = 20L + 25K + 5KL - 0.03L² - 0.02K²

Given, K = 5, i.e., capital is fixed. Therefore, the total product of labor, average product of labor, and marginal product of labor are:

TPL = f(L, K = 5) = 20L + 25 × 5 + 5L × 5 - 0.03L² - 0.02(5)²

= 20L + 125 + 25L - 0.03L² - 5

= -0.03L² + 45L + 120

APL = TPL / L, or APL = 20 + 125/L + 5K - 0.03L - 0.02K² / L

= 20 + 25 + 5 × 5 - 0.03L - 0.02(5)² / L

= 50 - 0.03L - 0.5 / L

= 49.5 - 0.03L / L

MP = ∂TPL / ∂L

= 20 + 25 - 0.06L - 0.02K²

= 45 - 0.06L

The following diagram illustrates the TP, MP, and AP curves:

Figure: Total Product (TP), Marginal Product (MP), and Average Product (AP) curves

The production function demonstrates increasing marginal returns due to specialization when L is low enough, i.e., when L ≤ 750. The marginal product curve initially increases and reaches a maximum value of 45 units of output when L = 416.67 units. When L > 416.67, MP decreases, and when L = 750 units, MP becomes zero.

The MP curve's initial increase demonstrates that the production function displays increasing marginal returns due to specialization when L is low enough. This is because when the capital is fixed, an additional unit of labor will benefit from the fixed capital and will increase production more than the previous one.

In other words, Because of the specialised nature of the fixed capital, the MP curve first climbs to its maximum value, where each additional worker's productivity rises due to the marginal product of the fixed capital.

The APL curve initially rises due to the MP curve's increase and then decreases when MP falls because of the diminishing marginal returns.

(i) At t = 0.5 s, the voltage output is approximately 0.1737 volts, and the indicated pressure is approximately 129.18 psi.

(ii) The output reaches 5.0 volts approximately at t = 0.6764 s.

(i) At t = 0.5 s, we need to calculate the voltage output and the indicated pressure.

To find the voltage output, we first need to determine the resistance at t = 0.5 s using the given pressure-resistance relationship. Substituting p = 150 psi into the equation R = (0.15p km) p + 2.5 kΩ, we get R = (0.15 * 150) + 2.5 = 25 + 2.5 = 27.5 kΩ.

Next, we can calculate the voltage output using the voltage-resistance relationship. Substituting R = 27.5 kΩ into V = (0.15p em) R / (R + 10 kΩ), we get V = (0.15 * 150 * e^-27.5) * 27.5 / (27.5 + 10) = 0.1737 volts.

To determine the indicated pressure, we can rearrange the voltage-resistance relationship and solve for p. Substituting V = 0.1737 volts and R = 27.5 kΩ, we get p = -ln[(40 * R * V) / (R + 10 kΩ)] / (0.15 * e^-R) = 129.18 psi.

Therefore, at t = 0.5 s, the voltage output is approximately 0.1737 volts, and the indicated pressure is approximately 129.18 psi.

(ii) To find the time at which the output reaches 5.0 volts, we need to determine the time constant and the corresponding time value.

Given that the sensor time constant is 350 ms, we know that the voltage will reach approximately 63.2% of its final value after one time constant. Therefore, the voltage at the time constant (t = τ) is V(τ) = 0.632 * 5.0 volts = 3.16 volts.

To find the time at which the voltage reaches 3.16 volts, we can solve for t in the voltage equation V = (0.15p em) R / (R + 10 kΩ). Rearranging the equation and substituting V = 3.16 volts, we get t = -ln[(R * V) / (40 * R - V * R - 10 kΩ)] / (0.15 * e^-R).

Calculating the value of R using the given pressure-resistance relationship for p = 150 psi, we get R = 27.5 kΩ. Substituting this value into the equation, we find t ≈ 0.6764 s.

Therefore, the output reaches 5.0 volts approximately at t = 0.6764 s.

To identify the vertical asymptotes, we have to factor the denominator. For horizontal asymptotes, we compare the degrees of the numerator and denominator.

For rational functions, there are vertical and horizontal asymptotes. To identify the vertical asymptotes, we first have to factor the denominator. After that, we should look for values that make the denominator zero. These values can be found by setting the denominator equal to zero and solving for x. The resulting x values would be the vertical asymptotes of the function.

The horizontal asymptote is the line that the function approaches as x goes towards infinity or negative infinity. For rational functions, the horizontal asymptote is found by comparing the degrees of the numerator and the denominator.

If the degree of the numerator is less than the degree of the denominator, the horizontal asymptote is y = 0. If the degree of the numerator is equal to the degree of the denominator, the horizontal asymptote is y = the ratio of the leading coefficients. If the degree of the numerator is greater than the degree of the denominator, there is no horizontal asymptote.

The Social Exchange Theory of interpersonal relationship satisfaction suggests that individuals are motivated to stay in a relationship as long as they feel that the rewards of the relationship are greater than the costs.

In the Social Exchange Theory of interpersonal relationship satisfaction, you would feel happiest in relationships when you feel that the rewards of the relationship equal or exceed its costs.

The Social Exchange Theory states that people evaluate their relationships in economic terms, with rewards being the benefits of the relationship and costs being the negatives. Rewards can include affection, attention, emotional support, sex, and companionship. Costs can include time, effort, money, and negative emotions such as stress, anxiety, and sadness.

According to the theory, individuals will be motivated to stay in a relationship as long as they feel that the rewards of the relationship are greater than the costs.

The opposite is also true; if individuals feel that the costs of the relationship are greater than the rewards, they will be motivated to leave the relationship.

Therefore, people are constantly evaluating their relationships to determine whether they are getting what they need from the relationship and whether it is worth continuing.

Scenario: A small business owner needs to analyze their sales data to make informed decisions about pricing and profitability.

Supporting Detail 1: The concept of linear equations can be applied to determine the break-even point and set optimal pricing strategies for the business.

Worked Example 1: Let's say the small business sells a product for $10 each, and the fixed costs (expenses that don't vary with the number of units sold) amount to $500. The variable costs (expenses that depend on the number of units sold) are $2 per unit. We can use the formula for a linear cost equation (C = mx + b) to find the break-even point where revenue equals total costs:

10x = 2x + 500

Simplifying the equation, we get:

8x = 500

x = 500/8

x = 62.5

The break-even point is 62.5 units. Knowing this information, the business owner can make decisions about pricing, cost control, and production targets.

Supporting Detail 2: The concept of systems of equations can be applied to optimize the allocation of resources in the business.

Worked Example 2: Let's consider a scenario where the business owner sells two different products. Product A generates a profit of $5 per unit, while Product B generates a profit of $8 per unit. The business owner has a limited budget of $500 and wants to determine the optimal allocation of resources between the two products. We can set up a system of equations to represent the profit constraints:

x + y = 500 (total budget)

5x + 8y = P (total profit, represented as P)

By solving this system of equations, the business owner can find the optimal values of x and y that maximize the total profit while staying within the budget constraints.

Conclusion: Applying concepts from this algebra course to real-life scenarios, such as analyzing sales data for a small business, helps in understanding the material by providing practical applications. It demonstrates the relevance of algebra in making informed decisions, optimizing resources, and maximizing profitability.

The he dependent and independent variables in this scenario represent the total cost of renting scuba equipment and the number of hours rented, respectively. and independent variables in this scenario represent the total cost of renting scuba equipment and the number of hours rented, respectively.

In this scenario, a vacation resort rents scuba equipment to certified divers with an upfront fee of $25 and a rate of $12 an hour.

The dependent variable is the total cost of renting the scuba equipment, while the independent variable is the number of hours the equipment is rented for. The dependent variable relies on the independent variable, as the total cost changes based on the hours rented.

To explain further, the independent variable (hours rented) can be freely chosen by the customer, and it doesn't depend on any other factor. On the other hand, the dependent variable (total cost) relies on the independent variable because the total cost will increase as the number of hours rented increases. In this case, the total cost is calculated by adding the upfront fee ($25) to the product of the hourly rate ($12) and the number of hours rented. This relationship can be expressed mathematically as:

Total Cost = $25 + ($12 × Hours Rented)
