The expression  [tex]\(2\cos^2(\theta) - 1\)[/tex] where θ is the lowercase Greek letter theta gives [tex]cos(\theta) = \pm 1/ \sqrt (2)[/tex].

The expression is [tex]\(2\cos^2(\theta) - 1\)[/tex].

Explanation:

1. 2: This is a coefficient that scales the result of the trigonometric function [tex]\(\cos^2(\theta)\)[/tex]. It simply doubles the value of the cosine squared term.

2. [tex]\(\cos^2(\theta)\)[/tex]: This is the square of the cosine of the angle [tex]\(\theta\)[/tex].

The cosine function cos takes an angle as input and returns the ratio of the adjacent side to the hypotenuse in a right triangle with that angle.

3. -1: This is a constant that is subtracted from the result of [tex]\(2\cos^2(\theta)\)[/tex]. Subtracting 1 shifts the trigonometric value downward by one unit on the y-axis.

Add 1 to both sides

[tex]2cos^2(\theta) =1[/tex]

Divide by 2 on both sides

[tex]cos^2(\theta) =1/2[/tex]

Take the square root of both sides

[tex]cos(\theta) = \pm 1/ \sqrt (2)[/tex]

The expression in question pertains to the conservation of momentum in physics, where trigonometric identities can simplify the calculation of particle velocities and directions after a collision. The included equations and concepts such as the conservation of momentum along an axis and the Pythagorean Theorem are essential components for solving problems in high school physics.

The expression 2cos2(θ)−1, where θ is the lowercase Greek letter theta, can be related to conservation of momentum in physics problems, particularly when analyzing collisions in two dimensions. Using trigonometric identities, such as tan θ = sin θ / cos θ, can be a useful technique in simplifying expressions and solving for unknown variables in mechanical physics.

In the context of conservation of momentum, equations may involve cosines and sines of angles representing the directions of particle velocities before and after a collision. For instance, if the scenario requires that the momentum along the x-axis be conserved, substituting sin θ / tan θ for cos θ could lead to simplifications where terms cancel out. A condition such as μ v2 cos(θ1−θ2)= 0 might imply that either the coefficient of friction μ is zero or the velocity component along the x-axis is zero, hence no momentum is transferred in that direction.

It is important to note that inverting mathematical functions is a common approach to solving equations in physics. Like in trigonometry, it may be necessary to 'undo' a function to isolate a variable, as shown in the example involving the Pythagorean Theorem to solve for side length of a triangle.

Final answer:

To find the amount of Drug Z in the 50 ml injection, set up a proportion based on the known concentration (125 mg in 250 ml). Solving for the unknown quantity gives 25 mg of Drug Z in the injection.

Explanation:

To determine how much of Drug Z is in a 50 ml injection when 250 ml of the medication contains 125 mg of Drug Z, you can use a proportion. The proportion can be set up as follows:

(125 mg of Drug Z) / (250 ml of medication) = (X mg of Drug Z) / (50 ml of medication)

To solve for X, which represents the amount of Drug Z in the 50 ml injection, you cross-multiply and divide:

(125 mg) × (50 ml) = (250 ml) × (X mg)

6250 mg·ml = 250 ml·X mg

Divide both sides by 250 ml to isolate X:

X = (6250 mg·ml) / (250 ml)

X = 25 mg of Drug Z

Therefore, the 50 ml injection contains 25 mg of Drug Z.

Answer:

Answer:

a. 4536, b. 2500, c. 500, d. 1080

Step-by-step explanation:

for every question we can use the numbers 0 - 9, this is 10 numbers in total (0, 1, 2, ,3 , 4, 5, 6, 7, 8, and 9).

Fore every case we have to check how many numbers we are allow to use in each digit.

"The number cannot start with zero" this left us with 9 options of numers for the first digit.

"no digits can be repeated." So if we already use one numer for the first, we can't repeat this in the second, and so on. So for the second numer we have 9 numbers as option (now we can use 0), for the third, since we already use 2 digits, we have 8 options, and for the last, we have 7

that results in: 9*9*8*7 = 4536

"The number must begin and end with an odd digit. " for odd digits we have 1, 3, 5, 7, 9 --> 5 options for the fist and last digit, and for the two middle digits, we have 10 options for each since it is allowed to repeat numbers

that results in: 5*10*10*5=2500

"The number must be at least 5000" So the first digit can use 5, 6, 7, 8, or 9 -->5 options for the fist digit

"and be divisible by 10." so it has to end in a 0, --> 1 option fot the last numer

and for the middle digits there are no restrictions, so we use the 10 options for each.

that results in: 5*10*10*1=500

"The number must be less than 3000 and must be even" for it to be less than 3000 it has to start with 0, 1 or 2 -> 3 options for the first digit

"and must be even" so the number has to end in 0, 2, 4, 6 or 8 --> 5 options for the last number

"No digits may be repeated in the last 3 digits." So we can't repeat in the middle number the one we put in the last digit, this gives us 9 options for the fist middle number and 8 for the second middle number

that results in: 3*8*9*5 = 1080

Final answer:

A step-by-step calculation is conducted for each condition to find the number of 4-digit numbers that can be formed using the digits 0-9 without repetition with conditions such as starting digit restrictions, parity, and divisibility. In total, there are 4536, 2500, 500, and 900 possible numbers for each condition respectively.

Explanation:

To calculate the number of 4-digit numbers meeting various conditions using the digits 0 through 9, we must consider each condition separately.

The ordinal number just before 152nd is 151st.

The ordinal number just before 152nd is 151st. Ordinal numbers are used to indicate position or order, and they are formed by adding the suffix '-st' to the cardinal number. In this case, the cardinal number 152 is changed to the ordinal number 152nd by adding '-nd' suffix. To find the ordinal number just before 152nd, we go one step back and change the '-nd' suffix to '-st', resulting in 151st.

The speed of the current is approximately 0.5 mph.

Let's assume the speed of the current is "c" mph. Zene's upstream speed is (3 - c) mph and downstream speed is (3 + c) mph.

The time taken for the upstream trip is 7 / (3 - c) hours, and the time for the downstream trip is 7 / (3 + c) hours.

Since the total trip time is 8 hours, we can set up the equation:

7 / (3 - c) + 7 / (3 + c) = 8

Solving this equation, we find the speed of the current is approximately 0.5 mph.

A boxplot offers us information that can be used to compare two variables. In particular, if one variable is quantitative and the other variable is qualitative, a boxplot is generated for each category of the qualitative variable. Therefore, through this graph it is possible to analyze the relationship between the amount of money spent on food and the gender of the person.

A circular diagram offers information for a single variable, especially of a qualitative type.

A histogram offers us information for a single variable, especially quantitative type.

A relational analysis between two variables could be done using options (D) or (E), however one of the variables of interest is of qualitative type and the other is of quantitative type, so the scatterplot and the two-way table.

Answer:

The weighted mean of the number of t-shirts sold per week is 5.6.

Step-by-step explanation:

Given : The data below represents the number of T-shirts sold per week by a student who started his own online t-shirt business.

T-Shirt Sold per Week([tex]x_i[/tex]) Frequency([tex]w_i[/tex])

         2                                                          1

4                                                          4

6                                                          7

8                                                          3

To find : The weighted mean of the number of t-shirts sold per week ?

Solution :

The formula of weighted mean is

[tex]\text{Weighted mean}=\frac{\sum (x_i\times w_i)}{\sum w_i}[/tex]

Substituting the values in the formula,

[tex]\text{Weighted mean}=\frac{2(1)+4(4)+6(7)+8(3)}{1+4+7+3}[/tex]

[tex]\text{Weighted mean}=\frac{2+16+42+24}{15}[/tex]

[tex]\text{Weighted mean}=\frac{84}{15}[/tex]

[tex]\text{Weighted mean}=5.6[/tex]

Therefore, The weighted mean of the number of t-shirts sold per week is 5.6.

Final answer:

To find the weighted mean of T-shirts sold per week, you multiply each amount by its frequency, sum these products, and then divide by the total frequency. For this data, the weighted mean is 5.6 T-shirts per week.

Explanation:

To calculate the weighted mean of the number of T-shirts sold per week, we must multiply each number of T-shirts sold by its respective frequency and then divide the sum by the total number of observations.

We have the following data:

6 * 7 = 42

Add these products together:

2 + 16 + 42 + 24 = 84

Next, calculate the total frequency (total number of weeks):

1 + 4 + 7 + 3 = 15

Now, divide the sum of products by the total frequency to get the weighted mean:

84 / 15 = 5.6

Therefore, the weighted mean number of T-shirts sold per week is 5.6.

Answer:

30

Step-by-step explanation:

I solved this question algebraically. First a variable (I used 'c') is introduced into the equation (for the number of correct answers). Thus we get the equation;

  2c - (40 - c) = 50

solving this...

  2c - 40 + c = 50

                3c = 90

                  c = 30

So the number of correct answers is 30. (30*2-10=50)

[Alternatively we can use a variable for the number of incorrect answers and get; 2* (40 - a) - a = 50, and solve this equation but this method is longer as you'll need to subtract this answer from 40 to get the number of correct responses.]

Answer:

Step-by-step explanation:

We know that between 1 to 10 there are 5 even and 5 odd numbers.

We could get 4 even cards , 4 odd cards or 2 odd and 2 even cards

Let´s check all this combinations

Case 1: When all 4 numbers are even:  

We are going to take 4 of the 5 even numbers in the box so we have

[tex]5C4=5[/tex]

Case 2: When all 4 numbers are odd:  

We are going to take 4 of the 5 odd numbers in the box, so we have

[tex]5C4=5[/tex]

Case 3: When 2 are even and 2 are odd:

We are giong to take 2 from 5 even and odd cards in the box so we have

[tex]5C2 * 5C2[/tex]

Remember that we obtain the probability from

[tex]\frac{Number-of-favourable-Outcome}{Total-number-of-outcomes}[/tex]

So we have the number of favourable outcomes but we need the Total cases for drawing four cards, so we have that:  

We are taking 4 of the 10 cards:

[tex]10C_4=210[/tex]

Hence we have that the probability that their sum is even

[tex]\frac{5+5+100}{210}=\frac{11}{21}[/tex]

Final answer:

To find the probability that the sum of the four cards drawn is even, we can break down the problem into two cases: drawing all four even-numbered cards or drawing two even-numbered cards and two odd-numbered cards. Using the multiplication rule, we calculate the probability for each case and add them together to get the total probability.

Explanation:

Total Number of Possible Outcomes: If we draw four cards from a box containing cards numbered 1 to 10, the total number of ways to do this is given by the combination formula,

resulting in  10!/4!(10-4)! = 210 possible outcomes.

Number of Ways to Get an Even Sum:

For the sum of the numbers on the four drawn cards to be even, there are two cases to consider:

1. All four cards have even numbers: There are 5 even-numbered cards out of 10, and we need to choose 4 of them. The number of ways to do this is  =5.

2. Three cards have odd numbers, and one card has an even number:

   There are 5 odd-numbered and 5 even-numbered cards.

   We need to choose 3 odd-numbered cards out of 5 and 1 even-  numbered card out of 5.

  The number of ways to do this is =50

Total Number of Ways for an Even Sum:

Adding the possibilities from both cases, we have a total of 5 + 50 = 55 ways to get an even sum.

The probability is then calculated as the ratio of the number of ways to get an even sum to the total number of possible outcomes:

Probability = Number of Ways to Get an Even Sum/Total Number of Possible Outcomes = 55/210= 11/42

Therefore, the probability that the sum of the numbers on the four drawn cards is even is 11/42.

Answer:

1) 35 distinct groups can be formed.

2) 18  distinct groups can be formed containing 2 men and 1 woman.

Step-by-step explanation:

The no of groups of 3 members that can be chosen from 7 members equals no of combinations of 3 members that can be formed from 7 members.

Thus no of groups =

[tex]n=\binom{7}{3}=\frac{7!}{(7-3)!\times 3!}=35[/tex]

thus 35 distinct groups can be formed.

Part b)

Now since the condition is that we have to choose 2 men and 1 women to form the group

let A and B be men member's of group thus we have to choose 2 member's from a pool of 4 men which equals

[tex]\binom{4}{2}=\frac{4!}{(4-2)!\times 2!}=6[/tex]

Let the Woman member be C thus we have to choose one woman from a pool of 3 women hence number of ways in which it can be done equals 3.

thus the group can be formed in [tex]6\times 3=18[/tex] different ways.

F = P(1+r)ⁿ

a. r = 15% = 0.15

18000 = 4309(1+0.15)ⁿ

18000/4309 = 1.15ⁿ

4.1773 = 1.15ⁿ

ln 4.1773 = ln 1.15ⁿ

ln 4.1773 = n*ln 1.15

n = ln 4.1773/ln 1.15

n = 10.2 years

b. r = 12% = 0.12

18000 = 4309(1+0.12)ⁿ

18000/4309 = 1.12ⁿ

4.1773 = 1.12ⁿ

ln 4.1773 = ln 1.12ⁿ

ln 4.1773 = n*ln 1.12

n = ln 4.1773/ln 1.12

n = 12.6 years

c. r = 19% = 0.19

18000 = 4309(1+0.19)ⁿ

18000/4309 = 1.19ⁿ

Answer: The patient receives [tex]200\ \mu g[/tex] daily.

The  prescription will last 30 days .

Step-by-step explanation:

Given : Prescription= Two sprays into each nostril once daily.

That means total sprays for both nostrils = [tex]2\times2=4[/tex] [∵ 1 nostrils in each nose.]

If each spray contains [tex]50 \mu g[/tex] of drug, then the amount of drug received by patient daily :-

[tex]4\times50=200\ \mu g[/tex]

Thus , the patient receives [tex]200\ \mu g[/tex] daily.

Also, the container can deliver a  total of 120 sprays.

Then, the number of days of use will the  prescription last the patient will be:_

[tex]\dfrac{120}{4}=30[/tex]

Hence,  the  prescription will last 30 days of use .

Final answer:

The patient will receive 200 micrograms of mometasone furoate monohydrate daily, and the prescription will last for 30 days.

Explanation:

The question involves calculating the total dosage of mometasone furoate monohydrate received daily by a patient and determining how many days the prescription will last, based on the dose and the number of sprays available.

To find the daily dose, we can multiply the number of sprays per nostril by the dosage per spray and the number of nostrils:

2 sprays/nostril × 50 μg/spray × 2 nostrils = 200 μg/day

The patient receives 200 micrograms daily.

To find out how many days the prescription will last:

120 sprays/container ÷ (2 sprays/nostril × 2 nostrils) = 120 sprays/container ÷ 4 sprays/day = 30 days

The prescription will last the patient for 30 days.

Let's suppose "good" here means that the amount a player can expect to win is positive.

The probability of drawing a heart from the deck is 13/52 = 1/4.

The probability of drawing a face card that is not a heart is 9/52.

The probability of drawing anything else is 30/52 = 15/26.

The expected winnings are then 10(1/4) + 8(9/52) - 6(15/26) = 11/26, meaning on average the player can expect to win about $0.42 per game, so by our definition this game is a "good" way to make money.

Statistically speaking, a player would gain 42 cents per game in the long run, making this gambling game potentially profitable.

This is determined by computing expected value, which takes into account the gains or losses for each possible outcome and the probability of each outcome.

The subject of this question is probability with reference to a game of cards. To evaluate whether or not the game is a good idea, we need to determine the expected value of the game, which is calculated by multiplying the value of each outcome by their probability and then summing these products. Here's how finances from the game might play out statistically:

The expected value of one round of the game is thus (0.25 x $10) + (0.173 x $8) + (0.577 x -$6) = $2.5 + $1.38 - $3.46 = $0.42. Therefore, statistically speaking, a player would gain 42 cents per game in the long run, making this gambling game potentially profitable.

[tex]x,y\geq 0[/tex]

The related line of both inequalities are solid lines because the sign of inequalities are ≤ and ≥. It means the points lie on related line are included in the solution set.

Check both inequalities by (0,0).

[tex]2(0)+4(0)\geq 20[/tex]

[tex]0\geq 20[/tex]

This statement is not true. So, the shaded region of inequality (1) will not contain the origin.

[tex]3(0)+2(0)\leq 24[/tex]

[tex]0\leq 24[/tex]

This statement is true. It means the shaded region of inequality (2) will contain the origin.

[tex]x,y\geq 0[/tex] means first quadrant.

The common shaded region is feasible region. The vertices of feasible region are (0,5), (0,12) and (7,1.5).

Calculate the value of objective function at these vertices.

For (0,5)

Step-by-step explanation:

sold toys = 4694

average profit on each toy = $2.95

total profit in the three months = $2.95 * 4694 = $13847.30

If 57% of the houses take more than three months to sell, there is a 2.6% chance that a random sample proportion would be as high as or higher than the one they obtained.

The appropriate conclusion is that if 57% of the houses take more than three months to sell, there is a 2.6% chance that a random sample proportion would be as high as or higher than the one they obtained. This means that the result is statistically significant, indicating that the proportion of houses that take more than three months to sell is likely higher than 57%.

[tex]U'(7000)=-0.000012(7000)^2+0.05(7000)+100 = -138[/tex]

Step-by-step explanation:

a) The marginal cost function is given by the derivative of the total cost function, in this way the marginal cost function for this company is:

[tex]\frac{dC(q)}{dq} = \frac{dC(q)}{dq} (0.000004q^ 3 - 0.03q ^ 2 + 100q + 75000) = 0.000012q^2 -0.06q + 100[/tex]

b) The income function is given by the relation [tex]R (q) = P (q) q = -0.005q^2 + 200q[/tex].

The marginal revenue function for the company is given by the derivative of the revenue function, in this way the marginal revenue function is:

[tex]\frac{dR(q)}{dq}= -0.01q+200[/tex]

(c) The profit function of the company is given by the relation [tex]U (q) = R (q) - C (q)[/tex], and the marginal utility function is given by the derivative of the utility function, in this way , the marginal utility function is:

[tex]\dfrac{dU(q)}{dq}=R'(q) - C'(q) = -0.01q+200 - (0.000012q^2-0.06q+100) = -0.000012q^2+0.05q+100[/tex]

When q = 2000, the marginal utility is:

[tex]U'(2000)=-0.000012(2000)^2+0.05(2000)+100 = 152[/tex]

When q = 7000, the marginal utility is:

[tex]U'(7000)=-0.000012(7000)^2+0.05(7000)+100 = -138[/tex]

Answer:

we are applying 70 ml during the whole day

Step-by-step explanation:

First, it is necessary to calculate the percentage of the drug that is left in the evening. This is calculated as:

100% - (35% + 25%) = 100% - 60% = 40%

Because,  35% is the percentage of the drug apply at the morning and 25% is percentage of the drug apply at afternoon.

Then, 40% is the percentage of the drug that is left in the evening and it is equivalent to 28 mL. So, the milliliter that we apply during the whole day are the milliliters equivalent to the 100%. We can calculate this by a rule of three as:

40% -------------------- 28 mL

100% -------------------    X

Where X are the milliliters that we apply during the whole day. Solving for X, we get:

[tex]X=\frac{100*28}{40}=70 mL[/tex]

Answer:

d = 6 sin(2π/7 t + 3π/2)

Step-by-step explanation:

Equation for simple harmonic motion is:

d = A sin(2π/T t + B) + C

where A is the amplitude,

T is the period,

B is the horizontal shift (phase shift),

and C is the vertical shift.

Given that A = 6, T = 7, and C = 0:

d = 6 sin(2π/7 t + B)

At t = 0, the buoy is at d = -6:

-6 = 6 sin(2π/7 (0) + B)

-1 = sin(B)

3π/2 = B

d = 6 sin(2π/7 t + 3π/2)

Notice you can also use cosine instead of sine and get a different phase shift.

d = 6 cos(2π/7 t + π)

You can even use phase shift properties to simplify:

d = -6 cos(2π/7 t)

Any of these answers are correct.

The equation modeling the displacement d of the buoy as a function of time is d(t) = 6 * sin(2π/7 * t) - 6.

To model the displacement d of the buoy as a function of time t, we can use the equation:

d(t) = A * sin(2π/T * t) + C

where A is the amplitude, T is the period, t is the time, and C is the vertical displacement at t = 0 seconds.

In this case, the amplitude A is 6ft, the period T is 7 seconds, and the vertical displacement at t = 0 seconds C is -6ft and the buoy initially moves upward. Therefore, the equation modeling the displacement as a function of time is:

d(t) = 6 * sin(2π/7 * t) - 6

Hello, Your question is already answered but I wanted to add something else if you dont mind :) Inhalants can cause sudden death.

Step-by-step explanation:

Inhalants can kill you instantly. Inhalant users can die by suffocation, choking on their vomit, or having a heart attack. Most teenagers also consider Inhalants as relaxation, like when your stressed or if you've seen in most movies, people panic and then breath in paper bag. I'm not sure if those are the inhalers your talking about but It said 10 points so why not? Thank you, have a great day :)

The albuterol inhaler can deliver 200 inhalation-doses.

1 mg = 1000 μg

So, 18 mg = 18 * 1000 μg = 18000 μg

Number of inhalation-doses = Total albuterol / Amount per dose

Number of inhalation-doses = 18000 μg / 90 μg/dose

Number of inhalation-doses =  200 inhalation-doses

Therefore, the albuterol inhaler can deliver 200 inhalation-doses.

Answer:

The probability is 0.5086

Step-by-step explanation:

The probability P that at least one of these three modules will fail to work properly is calculated as:

P = 1 - P'

Where P' is the probability that all the modules works properly. So, P' os calculated as:

P' = 0.9 * 0.84 * 0.65

P' = 0.4914

Because 0.9 is the probability that module 1 works properly, 0.84 is the probability that module 2 works properly and 0.65 is the probability that module 3 works properly.

Finally, the probability P that at least one of these three modules will fail to work properly is:

P = 1 - 0.4914

P = 0.5086
