Therefore, we have proved that if A ⊂ B, then inf A ≥ inf B.

Let A, B be nonempty subsets of R that are bounded below. We have to prove that if A ⊂ B, then inf A ≥ inf B.

Let's begin the proof:

We know that since A is a non-empty subset of R and is bounded below, therefore, inf A exists.

Similarly, since B is a non-empty subset of R and is bounded below, therefore, inf B exists. Also, we know that A ⊂ B, which means that every element of A is also an element of B. As a result, we can conclude that inf B ≤ inf A because inf B is less than or equal to each element of B and since each element of B is an element of A, therefore, inf B is less than or equal to each element of A as well.

Therefore, we have proved that if A ⊂ B, then inf A ≥ inf B.

(i) The required relation is (MA + MB)/Mo = (a/A)³ T² yrs.

(ii) The required ratio is 7.20.

(iii) MA/Mo = 0.413 and MB/Mo = 0.587.

Part (i) We are given the period T of the binary star system as 49.94 years.

The masses of the two components are MA and MB respectively.

Their orbits are circular and have radii TA and TB.

By Kepler's law: (MA + MB) TA² = (4π²)TA³/(G T²) (MA + MB) TB² = (4π²)TB³/(G T²) where G is the universal gravitational constant.

Now, let A be the mean sun-earth distance.

Therefore, TA/A = (1 au)/(TA/A) and TB/A = (1 au)/(TB/A).

Hence, (MA + MB)/Mo = ((TA/A)³ T² yrs)/[(A/TA)³ G yrs²/Mo] = ((TB/A)³ T² yrs)/[(A/TB)³ G yrs²/Mo] where Mo is the mass of the sun.

Thus, (MA + MB)/Mo = (TA/TB)³ = (TB/TA)³.

Hence, (MA + MB)/Mo = [(TB/A)/(TA/A)]³ = (a/A)³, where a is the separation between the stars.

Therefore, (MA + MB)/Mo = (a/A)³.

Hence, the required relation is (MA + MB)/Mo = (a/A)³ T² yrs.

This relation is identical to that for the Sun-Earth system, with a different factor in front of it.

Part (ii) Let the distance to the binary system be D.

Therefore, D = 1/P = 2.65 kpc (kiloparsec).

Now, let M be the relative mass of the two components of the binary system.

Therefore, M = MB/MA. By Kepler's law, we have TA/TB = (MA/MB)^(1/3).

Therefore, TB = TA (MA/MB)^(2/3) and rg = a (MB/(MA + MB)).

We are given a = 7.62" and P = 0.377".

Therefore, TA = (P/A)" = 7.62 × (A/206265)" = 0.000037 A, and rg = 0.0000138 a.

Therefore, TB = TA(MA/MB)^(2/3) = (0.000037 A)(M)^(2/3), and rg = 0.0000138 a = 0.000105 A(M/(1 + M)).

We are required to find a/A = rg/TA. Hence, (a/A) = (rg/TA)(1/P) = 0.000105/0.000037(0.377) = 7.20.

Therefore, the required ratio is 7.20.

Part (iii) The ratio of the distances of A and B from the center  of mass is 0.466.

Therefore, let x be the distance of A from the center of mass.

Hence, the distance of B from the center of mass is 1 - x.

Therefore, MAx = MB(1 - x), and x/(1 - x) = 0.466.

Therefore, x = 0.316.

Hence, MA/MB = (1 - x)/x = 1.16.

Therefore, MA + MB = Mo.

Thus, MA = Mo/(1 + 1.16) = 0.413 Mo and MB = 0.587 Mo.

Therefore, MA/Mo = 0.413 and MB/Mo = 0.587.

(i) The required relation is (MA + MB)/Mo = (a/A)³ T² yrs.

(ii) The required ratio is 7.20.

If the line segment AB has the endpoints A(4,−2) and B(−1,5), the midpoint of AB is (1.5, 1.5). and the length of AB is √74, which is approximately 8.60.

a) To find the midpoint of the line segment AB, we can use the midpoint formula. The midpoint is the average of the x-coordinates and the average of the y-coordinates of the endpoints. Given that A(4, -2) and B(-1, 5), we can calculate the midpoint as follows:

Midpoint = ((x₁ + x₂) / 2, (y₁ + y₂) / 2)

= ((4 + (-1)) / 2, (-2 + 5) / 2)

= (3/2, 3/2)

= (1.5, 1.5)

Therefore, the midpoint of AB is (1.5, 1.5).

b) To find the length of the line segment AB, we can use the distance formula. The distance between two points (x₁, y₁) and (x₂, y₂) is given by the formula:

Distance = √((x₂ - x₁)² + (y₂ - y₁)²)

Using the coordinates of A(4, -2) and B(-1, 5), we can calculate the length of AB as follows:

Distance = √((-1 - 4)² + (5 - (-2))²)

= √((-5)² + (7)²)

= √(25 + 49)

= √74

Therefore, the length of AB is √74, which is approximately 8.60.

The student's statement that the order of subtraction doesn't matter in either the slope or the distance formula is not correct.

In mathematical formulas, the order of operations is crucial, and changing the order of subtraction can lead to different results. Let's examine the two formulas separately to understand why this is the case. Slope formula: The slope formula is given by the equation (y2 - y1) / (x2 - x1), where (x1, y1) and (x2, y2) are two points on a line. The numerator represents the difference in y-coordinates, while the denominator represents the difference in x-coordinates. If we change the order of subtraction in the numerator or denominator, we would obtain different values. For example, if we subtract y1 from y2 instead of y2 from y1, the sign of the slope will be reversed.

Distance formula: The distance formula is given by the equation sqrt((x2 - x1)^2 + (y2 - y1)^2), where (x1, y1) and (x2, y2) are two points in a plane. The formula calculates the distance between the two points using the Pythagorean theorem. Similarly, if we change the order of subtraction in either (x2 - x1) or (y2 - y1), the result will be different, leading to an incorrect distance calculation.

In both cases, the order of subtraction is significant because it determines the direction and magnitude of the difference between the coordinates. Changing the order of subtraction would yield different values and, consequently, incorrect results in the slope or distance calculations. Therefore, it is important to maintain the correct order of subtraction in these formulas to ensure accurate mathematical calculations.

The shortest arc length from point A to point B on Earth's equator, given that the measure of △ACB is 74° and the circumference of Earth at the equator is approximately 40070 km, is approximately 16474 km.

To find the shortest arc length between points A and B, we can use the concept of central angles. The measure of △ACB is given as 74°, which is also the measure of the central angle at the center of Earth, point C. The circumference of Earth at the equator represents a full 360° rotation. Since the central angle of △ACB is 74°, we can calculate the ratio of the central angle to the full 360° rotation and find the corresponding arc length.
The ratio of the central angle to the full rotation is 74° / 360°. Multiplying this ratio by the circumference of Earth at the equator gives us the arc length between points A and B. Therefore, the shortest arc length is approximately (74° / 360°) * 40070 km ≈ 8237 km.
Hence, the correct answer is option d: 8237 km, which is the closest rounded kilometer to the calculated arc length.

Given the equation of the line as -2x+5y = 10. We can write the equation of the line in slope-intercept form by solving it for y. Doing so, we get:5y = 2x + 10y = (2/5)x + 2The slope-intercept form of a line is given as y = mx + b, where m is the slope of the line and b is the y-intercept. From the above equation, we can see that the slope of the given line is 2/5 and the y-intercept is 2.

Now we can graph the line by plotting the y-intercept (0, 2) on the y-axis and using the slope to find other points on the line. For example, we can use the slope to find another point on the line that is one unit to the right and two-fifths of a unit up from the y-intercept. This gives us the point (1, 2.4). Similarly, we can find another point on the line that is one unit to the left and two-fifths of a unit down from the y-intercept. This gives us the point (-1, 1.6).

Shante will need to catch 32 ladybugs on the fifth day in order to have an average of 20 ladybugs per day over 5 days.

To get the required average of 20 ladybugs, Shante needs to catch 100 ladybugs in 5 days.

Let x be the number of ladybugs she has to catch on the fifth day.

She has caught 17 ladybugs every 4 days:

Thus, she would catch 4 sets of 17 ladybugs = 4 × 17 = 68 ladybugs in the first four days.

Hence, to get an average of 20 ladybugs in 5 days, Shante will have to catch 100 - 68 = 32 ladybugs in the fifth day.

Solution 1: To solve the problem algebraically:

Let x be the number of ladybugs she has to catch on the fifth day.

Therefore the equation becomes:17 × 4 + x = 100 => x = 100 - 68 => x = 32

Solution 2: To solve the problem using arithmetic:

To get an average of 20 ladybugs, Shante needs to catch 20 × 5 = 100 ladybugs in 5 days. She has already caught 17 × 4 = 68 ladybugs over the first 4 days.

The function f(x) = x * sin^3(x) is an odd function. We can see that f(-x) = -f(x) for all values of x, which means the function is odd.

To determine if the function is even, odd, or neither, we need to check its symmetry properties with respect to the y-axis and the origin.

For a function to be even, it must satisfy the condition f(x) = f(-x) for all values of x. This means that if we replace x with -x in the function, the resulting expression should be equivalent to the original function.

For a function to be odd, it must satisfy the condition f(x) = -f(-x) for all values of x. This means that if we replace x with -x in the function, the resulting expression should be the negation of the original function.

In the case of f(x) = x * sin^3(x), let's evaluate f(-x):

f(-x) = (-x) * sin^3(-x)

Since sin(-x) = -sin(x), we can rewrite the expression as:

f(-x) = -x * (-sin(x))^3

Simplifying further:

f(-x) = -x * (-1)^3 * sin^3(x)

     = -x * sin^3(x)

     = -f(x)

Answer:

the value of the given particular integral is 0 because 0 + 0 = 0.

Step-by-step explanation:

We are given the following integral:

1/((D^2) +4){2 sin(x) cos(x) + 3 cos(x)}

Let's simplify the denominator first:

(D^2 + 4) = (D^2 + 2^2)

This can be written as:

(D + 2i)(D - 2i)

Now let's express the numerator in partial fractions:

2 sin(x) cos(x) + 3 cos(x) = A(D + 2i) + B(D - 2i)

Solving for A and B:

Let D = -2i, then we have:

A(-2i + 2i) = 3(-2i)

0 = -6i

This implies that A = 0.

Similarly, when we let D = 2i, we obtain:

B(2i - 2i) = 3(2i)

0 = 6i

This implies that B = 0.

Therefore, the original integral simplifies to:

0 + 0 = 0

The radius of the wax candle is approximately 4.217 cm. To find the radius of the wax candle, we can use the formula for the volume of a cone:

V = (1/3) * π * r^2 * h,

where V is the volume, π is pi (approximately 3.14159), r is the radius, and h is the height of the cone.

In this case, we are given that the height of the candle is 9 cm and the volume of wax is approximately 167.55 cubic cm.

167.55 = (1/3) * 3.14159 * r^2 * 9.

To find the radius, we can rearrange the equation:

r^2 = (3 * 167.55) / (3.14159 * 9).

r^2 = 167.55 / 9.425.

r^2 ≈ 17.808.

8. the confidence interval for the proportion of Americans who believe high school graduates are prepared for college is approximately (0, 0.02634) with a 95% confidence level.

7. To determine whether the poll was fair or biased, we need more information about the methodology used for sampling. The sample should be representative of the population to ensure fairness. If the sampling method was random and ensured a diverse and unbiased representation of the adult population across all 50 states, then the poll can be considered fair. However, without specific information about the sampling methodology, it is difficult to make a definitive judgment.

8. To calculate the confidence interval, we can use the formula:

  Margin of Error = z * √(p * (1 - p) / n)

   Where:

   - z is the z-score corresponding to the desired confidence level (for 95% confidence, it is approximately 1.96).

   - p is the proportion of adults who believe high school graduates are prepared.

   - n is the sample size.

   We can rearrange the formula to solve for the proportion:

   p = (Margin of Error / z)²

   Plugging in the values:

   p = (0.026 / 1.96)² ≈ 0.0003406

   The confidence interval can be calculated as follows:

   Lower bound = p - Margin of Error

   Upper bound = p + Margin of Error

   Lower bound = 0.0003406 - 0.026 ≈ -0.0256594

   Upper bound = 0.0003406 + 0.026 ≈ 0.0263406

However, since the proportion cannot be negative or greater than 1, we need to adjust the interval limits to ensure they are within the valid range:

Adjusted lower bound = max(0, Lower bound) = max(0, -0.0256594) = 0

Adjusted upper bound = min(1, Upper bound) = min(1, 0.0263406) ≈ 0.0263406

Therefore, the confidence interval for the proportion of Americans who believe high school graduates are prepared for college is approximately (0, 0.02634) with a 95% confidence level.

9. This confidence interval suggests that with 95% confidence, the proportion of Americans who believe high school graduates are prepared for college lies between 0% and 2.634%.

The woman would need to invest approximately $615,315.32 in a life income annuity earning 4% APR to receive $3500 per month in income for an expected lifetime of 237 more months.

To calculate the amount the woman would need to invest in a life income annuity to receive $3500 per month in income for an expected lifetime of 237 more months, we need to consider the interest rate and the time period.

Given:

- Monthly income needed: $3500

- Expected lifetime in months: 237

- Annual Percentage Rate (APR): 4%

First, we need to convert the monthly income to an annual income by multiplying it by 12:

Annual income needed = $3500 * 12 = $42,000

To calculate the amount required to invest in the annuity, we need to use the present value formula for an annuity. The formula is:

Present Value = Annual income needed * (1 - (1 + r)^(-n)) / r

Where:

- r is the monthly interest rate (APR divided by 12)

- n is the total number of months (expected lifetime)

Now, let's plug in the values into the formula and calculate the present value:

r = 4% / 12 = 0.04 / 12 = 0.00333 (rounded to 5 decimal places)

n = 237

Present Value = $42,000 * (1 - (1 + 0.00333)^(-237)) / 0.00333

Using a calculator, we can evaluate the expression within the parentheses first:

(1 + 0.00333)^(-237) ≈ 0.5113

Substituting this value back into the formula:

Present Value = $42,000 * (1 - 0.5113) / 0.00333

Simplifying further:

Present Value ≈ $42,000 * 0.4887 / 0.00333

Using a calculator, we find:

Present Value ≈ $615,315.32

Therefore, the woman would need to invest approximately $615,315.32 in a life income annuity earning 4% APR to receive $3500 per month in income for an expected lifetime of 237 more months.

The given values are:s = -3t = -3and

cos s= 12/13

(a) sin (s+t) = sin s cos t + cos s sin t

We know that:sin s = -3/5cos s

= 12/13sin t

= -3/5cos t

= -4/5

Therefore,sin (s+t) = (-3/5)×(-4/5) + (12/13)×(-3/5)sin (s+t)

= (12/65) - (36/65)sin (s+t)

= -24/65(b) tan (s+t)

= sin (s+t)/cos (s+t)tan (s+t)

= (-24/65)/(-12/13)tan (s+t)

= 2/5(c) Quadrant of s+t:

As per the given information, s and t are in the IV quadrant, which means their sum, i.e. s+t will be in the IV quadrant too.

The IV quadrant is characterized by negative values of x-axis and negative values of the y-axis.

Therefore, sin (s+t) and cos (s+t) will both be negative.

The values of sin (s+t) and tan (s+t) are given above.

The value of cos (s+t) can be determined using the formula:cos^2 (s+t) = 1 - sin^2 (s+t)cos^2 (s+t)

= 1 - (-24/65)^2cos^2 (s+t)

= 1 - 576/4225cos^2 (s+t)

= 3649/4225cos (s+t)

= -sqrt(3649/4225)cos (s+t)

= -61/65

Now, s+t is in the IV quadrant, so cos (s+t) is negative.

Therefore,cos (s+t) = -61/65

The NPV of the acquisition for Bidder Inc. is $1,488,921.30.

To calculate the Net Present Value (NPV) of the acquisition for Bidder Inc., we need to consider the cash flows associated with the acquisition and discount them to their present value.

1. Calculate the cash flows:

  - Bidder Inc.'s cash outflow: The cost of acquiring Target Inc., which is the product of Bidder's price per share ($57) and the number of shares outstanding of Target Inc. (240,000).

- Target Inc.'s cash inflow: The value of Target Inc.'s shares in the share exchange, which is the product of Target Inc.'s price per share ($48) and the number of shares outstanding of Target Inc. (240,000).

2. Determine the present value of cash flows:

  - Apply a discount rate to the cash flows to bring them to their present value. The discount rate represents the required rate of return or cost of capital for Bidder Inc. Let's assume a discount rate of 10%.

3. Calculate the NPV:

  - Subtract the present value of the cash outflow from the present value of the cash inflow.

Now let's calculate the NPV using the provided values:

1. Cash flows:

  - Bidder Inc.'s cash outflow = $57 x 240,000 = $13,680,000

  - Target Inc.'s cash inflow = ($48 x 240,000) + (0.24 x $48 x 240,000) = $13,824,000

2. Present value of cash flows:

  - Apply a discount rate of 10% to bring the cash flows to their present value.

  - Present value of Bidder Inc.'s cash outflow = $13,680,000 / (1 + 0.10) = $12,436,363.64

  - Present value of Target Inc.'s cash inflow = $13,824,000 / (1 + 0.10) = $12,567,272.73

3. NPV:

  - NPV = Present value of Target Inc.'s cash inflow - Present value of Bidder Inc.'s cash outflow

  - NPV = $12,567,272.73 - $12,436,363.64 = $130,909.09

However, in the given answer, the NPV is stated as $1,488,921.30. It is possible that there might be some additional cash flows or considerations not mentioned in the problem statement that result in this different value.

Without further information or clarification, it is not possible to determine how the given answer was obtained.

The expression is equivalent to \(-\sin \theta\).

The expression \(\cos (-\theta) \cdot \tan (-\theta) \cdot \csc \theta\) is equivalent to \(-\sin \theta\) for values of \(\theta\) where the expression is defined. When evaluating the given expression, we can use trigonometric identities to simplify it. The cosine of the negative angle \(-\theta\) is equal to the cosine of \(\theta\), the tangent of the negative angle is equal to the negative tangent of \(\theta\), and the cosecant of \(\theta\) is equal to the reciprocal of the sine of \(\theta\).

The unpaid balance after 25 years is $28,961.27.

To find the monthly payment, we can use the formula:

P = (A/i)/(1 - (1 + i)^(-n))

where P is the monthly payment, A is the loan amount, i is the monthly interest rate (6%/12 = 0.005), and n is the total number of payments (30 years x 12 months per year = 360).

Plugging in the values, we get:

P = (134829.3*0.005)/(1 - (1 + 0.005)^(-360)) = $805.23

Therefore, the monthly payment is $805.23.

To find the unpaid balance after 10 years (120 months), we can use the formula:

B = A*(1 + i)^n - (P/i)*((1 + i)^n - 1)

where B is the unpaid balance, n is the number of payments made so far (120), and A, i, and P are as defined above.

Plugging in the values, we get:

B = 134829.3*(1 + 0.005)^120 - (805.23/0.005)*((1 + 0.005)^120 - 1) = $91,955.54

Therefore, the unpaid balance after 10 years is $91,955.54.

To find the unpaid balance after 20 years (240 months), we can use the same formula with n = 240:

B = 134829.3*(1 + 0.005)^240 - (805.23/0.005)*((1 + 0.005)^240 - 1) = $45,734.89

Therefore, the unpaid balance after 20 years is $45,734.89.

To find the unpaid balance after 25 years (300 months), we can again use the same formula with n = 300:

B = 134829.3*(1 + 0.005)^300 - (805.23/0.005)*((1 + 0.005)^300 - 1) = $28,961.27

the frequency of the C5+ photon is approximately 7.31 x 10^14 Hz, rounded to three significant figures.

The frequency of a photon can be calculated using the Bohr equation. In this case, we are considering a C5+ ion transitioning from energy level n=6 to n=2. The Bohr equation is given by:

ν = R_H * (1/n_f^2 - 1/n_i^2)

where ν is the frequency of the photon, R_H is the Rydberg constant (approximately 3.29 x 10^15 Hz), n_f is the final energy level, and n_i is the initial energy level.

Substituting the values into the equation, we have:

ν = 3.29 x 10^15 Hz * (1/2^2 - 1/6^2)

Simplifying the equation further, we get:

ν = 3.29 x 10^15 Hz * (1/4 - 1/36)

Calculating the value, we find:

ν = 3.29 x 10^15 Hz * (8/36)

ν ≈ 7.31 x 10^14 Hz
