The rate at which Warfarin leaves the body should be proportional to the amount still in the body, not a constant rate of 2.5. So the correct differential equation for part (b) is:

Q' = 0.5 - kQ, where Q(0) = 0

Where k is the proportionality constant for the rate of elimination.

Explanation

(a) Let's denote the rate of elimination as k, where k > 0. Since the elimination rate is proportional to the amount of warfarin, we can write the differential equation as:

Q'(t) = -kQ(t)

Given that the initial condition is a 2.5 mg pill, the initial condition should be:

Q(0) = 2.5

So the differential equation for part (a) is:

Q'(t) = -kQ(t), Q(0) = 2.5

(b) In this case, the patient receives warfarin intravenously at a rate of 0.5 mg/hour. Thus, we should add the rate of administration to our equation:

Q'(t) = 0.5 - kQ(t)

The initial condition is still that the patient has no warfarin in her system:

Q(0) = 0

So the differential equation for part (b) is:

Q'(t) = 0.5 - kQ(t), Q(0) = 0

The equation of line B is y = -3x + 8.

To find the equation of line B, which is parallel to line A and passes through point P, we need to determine the slope of line A and use it to write the equation of line B.

Looking at line A, we can observe that it has a slope of -3. This is because line A has a rise of -3 (decreasing y-values) for every run of 1 (constant x-values).

Since line B is parallel to line A, it will have the same slope of -3.

Now, we have the slope (-3) and the point P(x, y) through which line B passes. Let's use the point-slope form of the linear equation to write the equation of line B:

y - y1 = m(x - x1)

Substituting the values, we have:

y - (-7) = -3(x - 5)

Simplifying:

y + 7 = -3x + 15

To write the equation in the form y = mx + c, we rearrange the equation:

y = -3x + 15 - 7

y = -3x + 8

Therefore, the equation of line B is y = -3x + 8.

B. Subset

Step-by-step explanation:

A(n) subset is a member of a set

The number of elements that are common to S and T are 668 elements ,

the correct option is (d) .

In the question ,

it is given that ,

the set S is the set of 2005 positive multiple of 4

that is S = {4,8,12,16,....}

and the set T is the set of 2005 positive multiple of 6

that is T = {6,12,18,24,....}

and since the least common multiple , LCM of 4 and 6 is = 12,

So , elements that are common to set  S and T must be multiples of 12.

Since,  4 × 2005 = 8020 and 6 × 2005 = 12030,

the several multiples of 12 that are in set T won't be in set S,

but all multiples of 12 that are in set S will be in set T.

So we have to find the number of multiples of 12 that are in set S.

and since 4 × 3 = 12, that means every 3rd element of set S will be a multiple of 12.

which is = 2005/3 = 668 .

Therefore , there are 668 elements that are common .

The given question is incomplete , the complete question is

Ethical theories can help individuals find meaning in life by offering guidelines for how to live a morally virtuous or fulfilling life.

Consequentialism, for instance, focuses on the outcomes of actions and encourages individuals to maximize overall happiness or well-being. By striving to make a positive impact on others and society, individuals may find a sense of purpose and meaning in contributing to the greater good.

Deontology, on the other hand, emphasizes following ethical duties and principles regardless of the consequences. By adhering to moral rules and obligations, individuals may find meaning in their commitment to upholding values they deem important.

Virtue ethics centers around developing virtuous character traits and embodying moral excellence. By cultivating virtues such as compassion, integrity, and courage, individuals can find meaning in personal growth and the pursuit of a virtuous life.

Regarding the challenge to the meaning of life, one philosophical idea that could present a strong challenge is existential nihilism. This perspective argues that life lacks inherent meaning or purpose, and any attempts to find meaning are ultimately futile.

Answer: Length = 15 meters

Width = 2 meters

Step-by-step explanation:

Perimeter of a rectangle = 2l + 2w

Area of a rectangle = l × w

where l = length

w = width

Therefore,

2l + 2w = 34 ...... i

l × w = 30 ........ ii

From equation i

2l + 2w = 34

Divide through by 2.

l + w = 17 ...... iii

Then, l = 17 - w ........ iv

Put equation iv into ii

l × w = 30

(17 - w) × w = 30

17w - w² = 30

w² - 17w + 30 = 0

w² - 15w - 2w + 30 = 0

w(w - 15) - 2(w - 15) = 0

(w - 2) = 0

w = 0 + 2 = 2

w - 15 = 0

w = 0 + 15 = 15

Length = 15 meters

Width = 2 meters

Game theory is a branch of mathematics that deals with the study of decision-making in situations where two or more individuals or groups are involved.

It aims to predict the outcomes of these decisions by analyzing the strategies and incentives of each player. In the context of oligopoly, game theory helps us understand how firms interact and compete with each other in a market. Oligopoly is a market structure where a small number of large firms dominate the market. In this situation, firms must take into account the actions and reactions of their competitors when making decisions about pricing, production, and advertising. Game theory provides a framework for analyzing the strategic behavior of firms in an oligopolistic market. It helps us understand how firms may collude or engage in strategic behavior to gain an advantage over their competitors. It also provides insights into how changes in market conditions or government regulations can affect the behavior of firms in an oligopoly. I can say that visual aids and real-world examples can be helpful in understanding complex concepts like game theory. Video clips can be a great way to illustrate key ideas and make them more accessible to a wider audience. However, it is important to remember that game theory is a highly technical field and may require a significant amount of study and practice to fully grasp its concepts and applications.

The amount of time Jill spent to do her homework  

= 9 1/2 hours. which equals to  570 minutes.

Which means, the amount of times Jack needed to do his is  

= 570 minutes x 1.5

= 855 minutes which equals to 14 1/4 hours

hope this helps

Answer:

Step-by-step explanation:

1) Time spent by Jack = Time spent by Jill * 1  1/2

                                \(= 9\frac{1}{2}*1\frac{1}{2}\\\\=\frac{19}{2}*\frac{3}{2}\\\\=\frac{19*3}{2*2}\\\\=\frac{57}{4}\\\\=14\frac{1}{4} hours\)

2) Time spent by Jill = Time spent by Jack ÷  1 1 /2

                                 = 18 1/4 ÷ 1 1/2

                                 = 73/ 4 ÷ 3/2

                                 \(= \frac{73}{4} * \frac{2}{3}\\\\=\frac{73}{2}*\frac{1}{3}\\\\=\frac{73*1}{2*3}\\\\=\frac{73}{6}\\\\=12\frac{1}{6} hours\)

3) Third number = Sum of three numbers - Sum of two numbers

Sum of two numbers = \(8\frac{2}{3}+8\frac{1}{6}\\\)

                                   \(= \frac{26}{3} +\frac{49}{6}\\\\=\frac{26*2}{3*2}+\frac{49}{6}\\\\=\frac{52}{6}+\frac{49}{6}\\\\=\frac{52+49}{6}\\\\=\frac{101}{6}\\\)

Third number = 22 8/15 - 101/6

                       \(= \frac{338}{15}- \frac{101}{6}\\\\= \frac{338*2}{15*2}- \frac{101*5}{6*5}\\\\= \frac{676}{30}- \frac{505}{30}\\\\= \frac{676-505}{30}\\\\= \frac{171}{30}\\\\=5 \frac{21}{30}\\\\= 5 \frac{7}{10}\)

Length of third side = 10 units.

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.

Here, given that,

Height = 7 units

Base = √51 units

And, we have, it is a right angle triangle  

and we have to find the hypotenuse.

By Pythagorean theorem we get,

Hypotenuse = √7²+ 51

                     =√100
