The order of reaction has a linear curve when plotting concentration versus time is second, the correct option is C.

The Order of reaction refers to the relationship between the rate of a chemical reaction and the concentration of the species taking part in it. In order to obtain the reaction order, the rate expression (or the rate equation) of the reaction in question must be obtained.

We are given that;

The plot is between concentration versus time

The curve is linear

Now,

The strength of the rate of dependency on the reactant concentration determines the reaction's order. Which gives, the rate of a first-order reaction will depend on the concentration of a single species, a second-order reaction will undoubtedly depend on the concentration of two species;

\(rate = k{[A]^x + [B]^y}\)

Therefore, for the given reaction the answer will be second order.

The price per T-shirt should be at least $15 to achieve a profit of $250.

To calculate the price per T-shirt that will yield a profit of at least $250, we need to consider the cost of production, the desired profit, and the number of shirts to be sold.

Given that the cost to make each T-shirt is $10, and we want to sell 50 shirts, the total cost of production would be 10 * 50 = $500.

Now, let's calculate the minimum revenue needed to achieve a profit of $250. We add the desired profit to the total cost of production: $500 + $250 = $750.

Finally, to determine the price per T-shirt, we divide the total revenue by the number of shirts: $750 ÷ 50 = $15.

Therefore, to make a profit of at least $250, the price per T-shirt should be set at $15.

By selling each T-shirt for $15, the total revenue would be $15 * 50 = $750. From this revenue, we subtract the total production cost of $500 to calculate the profit, which amounts to $750 - $500 = $250. Thus, by charging $15 per T-shirt, the desired profit of $250 is achieved.

Step-by-step explanation:

Answer:

t = 4, 9

Step-by-step explanation:

Hi there!

f(t) = t² - 13t + 36

Let f(t) = 0:

0 = t² - 13t + 36

Factor the equation:

0 = t² - 4t - 9t + 36

0 = t(t - 4) - 9(t - 4)

0 = (t - 9)(t - 4)

The zero-product property states that if the product of two numbers is zero, then one of the numbers is equal to zero. Therefore, either (t - 9) or (t - 4) is equal to zero:

t - 9 = 0

t = 9

t - 4 = 0

t = 4

Therefore, the zeros of the function are 4 and 9.

The type of sampling described, where the researchers intentionally select a sample with 50% straight and 50% LGBTQ+ respondents, is known as "disproportionate stratified sampling."

A. Disproportionate stratified sampling involves dividing the population into different groups (strata) based on certain characteristics and then intentionally selecting a different proportion of individuals from each group. In this case, the researchers are dividing the population based on sexual orientation (straight and LGBTQ+) and selecting an equal proportion from each group.

B. Availability sampling (also known as convenience sampling) refers to selecting individuals who are readily available or convenient for the researcher. This type of sampling does not guarantee representative or unbiased results and may introduce bias into the study.

C. Snowball sampling involves starting with a small number of participants who meet certain criteria and then asking them to refer other potential participants who also meet the criteria. This sampling method is often used when the target population is difficult to reach or identify, such as in hidden or marginalized communities.

D. Simple random sampling involves randomly selecting individuals from the population without any specific stratification or deliberate imbalance. Each individual in the population has an equal chance of being selected.

Given the description provided, the sampling method of intentionally selecting 50% straight and 50% LGBTQ+ respondents represents disproportionate stratified sampling.

The measure of ∠POX  = 160°  The length of XOA = 16.95 mm ,We know that PM¯, PN¯, and PO¯ are angle bisectors of triangle MNO, so they divide the opposite sides in two equal parts. Let x = MY, y = NY, and z = OY. Then, we have:

MX / NO = MY / NY (by the angle bisector theorem)

MX / (MX + XO) = x / (x + y)

MX(x + y) = x(MX + XO)

MXy = XOx

NO / OX = NY / OY (by the angle bisector theorem)

(OX + XO) / OX = y / z

1 + XO/OX = y/z

XO/OX = (z - y)/y

Now, we can use these equations to solve the problem:

To find PX¯, we need to find MX. Using the angle sum property of triangles, we have:

m∠M = 180 - m∠MON = 140°

m∠PMX = m∠M/2 = 70°

m∠PMO = m∠MON/2 = 20°

m∠XMO = m∠PMX + m∠PMO = 70° + 20° = 90°

Therefore, PX¯ is the altitude from M to XO¯, so we have:

tan(30°) = PX / MX

MX = PX / tan(30°)

= 23 / √(3)

= 13.31 mm

To find m∠PMX, we can use the fact that PM¯ is an angle bisector:

m∠PMX = m∠M + m∠PMO

= 140° + 20°

= 160°

To find m∠POX, we can use the fact that PO¯ is an angle bisector:

m∠POX = m∠O + m∠PNO

= 180° - m∠MON + m∠PNO

= 180° - 40° + 20°

= 160°

To find XO¯, we need to find y and z. Using the fact that PX¯ is an angle bisector, we have:

PY / OY = PM / OM

23 / z = 52 / (x + y + z)

y + z = 52z / 23

z = 23y / (52 - 23)

Using the equation XO/OX = (z - y)/y, we have:

XOA / 52 = (23y / (52 - 23) - y) / x

XOA= 52 * 23y / ((52 - 23) * x - 23y)

Substituting MX = 23/√(3) - PX = 23/√(3) - 13.31, we get:

y = NO * PY / (PM + PN + PO) = 56.17 mm

z = OY + PY = 79.17 mm

XOA = 16.95 mm

Therefore, the answers are:

Length of PX¯: 13.31 mm

Strategies such as fast-tracking, crashing, prioritization, and resource optimization can be employed to reduce the project completion time by 5 weeks.


To reduce the completion time of the project by 5 weeks, we need to analyze the provided information and make appropriate adjustments. The initial completion time of the project is 25 weeks.

To achieve a reduction of 5 weeks, we can consider several strategies:

1. Fast-tracking: This involves overlapping or parallelizing certain project activities that were initially planned to be executed sequentially. By identifying tasks that can be performed concurrently, we can potentially save time. However, it's important to evaluate the impact on resource allocation and potential risks associated with fast-tracking.

2. Crashing: This strategy focuses on expediting critical activities by adding more resources or adopting alternative approaches to complete them faster. By compressing the schedule of critical tasks, we can reduce the overall project duration. However, this may come at an additional cost.

3. Prioritization: By reevaluating the project tasks and their priorities, we can allocate resources more efficiently. This ensures that critical activities receive higher attention and are completed earlier, resulting in an accelerated project timeline.

4. Resource optimization: Analyzing the resource allocation and identifying potential areas for optimization can lead to time savings. By ensuring that resources are utilized effectively and efficiently, we can streamline the project execution process.

It's important to note that implementing any of these strategies requires careful evaluation, considering factors such as project constraints, risks, cost implications, and stakeholder agreements. A comprehensive analysis of the project plan, resource availability, and critical path can guide the decision-making process for reducing the project completion time.

The side lengths of the right triangle are shorter leg = 15 ft, longer leg = 20 ft, and hypotenuse = 25 ft. We can use the concept of the Pythagorean theorem

In this right triangle, let's denote the shorter leg as "x" and the longer leg as "x + 5". The hypotenuse is 5 ft longer than the longer leg, so it can be expressed as "x + 5 + 5". Using the Pythagorean theorem, we can set up an equation to solve for "x" and then calculate the lengths of both legs and the hypotenuse.

According to the Pythagorean theorem, in a right triangle, the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides. Applying this to the given triangle, we have:

x² + (x + 5)² = (x + 5 + 5)²

Simplifying the equation, we get:

x² + (x² + 10x + 25) = (x + 10)²

Expanding the equation, we have:

x² + x² + 10x + 25 = x² + 20x + 100

Combining like terms, we obtain:

2x² + 10x + 25 = x² + 20x + 100

Subtracting x² and 20x from both sides, we get:

x² - 10x + 25 = 100

Rearranging the terms, we have:

x² - 10x - 75 = 0

To solve this quadratic equation, we can factor it or use the quadratic formula. Factoring the equation, we have:

(x - 15)(x + 5) = 0

This gives us two possible solutions: x = 15 or x = -5. Since the lengths of the sides cannot be negative, we discard the negative value. Therefore, the shorter leg is 15 ft and the longer leg is 15 + 5 = 20 ft. The hypotenuse is then 20 + 5 = 25 ft.

In conclusion, the side lengths of the right triangle are: shorter leg = 15 ft, longer leg = 20 ft, and hypotenuse = 25 ft.
