The curve with polar equation r = 10sin(θ)cos(θ) can be expressed in Cartesian coordinates as \(x^2 + y^2 - 10xy = 0\)

To derive the Cartesian equation, we can use the identities x = r cos(θ) and y = r sin(θ) to substitute for r in the polar equation:

\(x^2 + y^2 = (10sin(\theta)cos(\theta))^{2}\)

Simplifying, we get:

\(x^2 + y^2 = 25x^{2}y^{2}\)

Rearranging, we obtain the final Cartesian equation:

\(x^2 + y^2 - 10xy = 0\)

This equation represents a special type of conic section known as a hyperbola. It has two branches that are symmetric about the line y = x/2. To visualize the curve, we can plot several points using the polar equation and convert them to Cartesian coordinates.

The revenue from hedging minus the revenue from not hedging receivables can be calculated by considering the net exposure to the Malaysian ringgit, the forward rate, and the probabilities of different exchange rate outcomes.

To calculate the revenue from hedging minus the revenue from not hedging receivables, we need to compare the outcomes of hedging versus not hedging in terms of the exchange rate.

If Money Corp. hedges its receivables, it will lock in the forward rate of $.23 for the net exposure of MYR1,500,000. Therefore, the revenue from hedging will be:

Revenue from Hedging = Net Exposure * Forward Rate = MYR1,500,000 * $.23

To calculate the revenue from not hedging, we consider the probabilities associated with each exchange rate outcome. The expected revenue from not hedging is calculated by multiplying each possible value by its corresponding probability and summing the results:

Expected Revenue from Not Hedging = (Revenue at $.20 * Probability of $.20) + (Revenue at $.25 * Probability of $.25)

The statements that accurately compare the domain and range of the functions are: The domain of all three functions is all real numbers, The range of f(x) and h(x) is all real numbers, but the range of g(x) is all real numbers except 0.

The domain of a function refers to all the possible input values that make the function defined. For the quadratic function f(x) = 3x², there are no values of x that make the function undefined, so the domain of f(x) is all real numbers. To find the range of f(x), we can calculate the vertex of the parabola, which is (0,0). The range of f(x) is all real numbers greater than or equal to zero.

For the quadratic function f(x) = 3x², we can determine the vertex using the formula:

h = -b/2a

In this case, a = 3 and b = 0, so:

h = -0/2(3) = 0/6 = 0

The x-coordinate of the vertex is 0.

To find the y-coordinate, we evaluate the function at the vertex:

f(0) = 3(0)² = 0

So the vertex of the parabola is (0,0).

Since the coefficient of x² is positive, the parabola opens upwards, and the minimum value of the function occurs at the vertex. Therefore, the range of f(x) is all real numbers greater than or equal to zero.

For the rational function g(x) = 1/3x, the function is undefined when the denominator is equal to zero. Thus, we solve for the value(s) of x that make the denominator zero:

3x = 0

Dividing both sides by 3, we get:

x = 0

Therefore, the domain of g(x) is all real numbers except zero. The range of g(x) is all real numbers except zero, since the function cannot equal zero.

For the linear function h(x) = 3x, there are no values of x that make the function undefined. Thus, the domain of h(x) is all real numbers. The range of h(x) is also all real numbers, since the function is a straight line that passes through the origin and extend infinitely in both directions.

The problem with Rodell's method for collecting data is that it may result in a biased sample.

Rodell is only polling the students on his football and basketball teams, which means the sample he collects is not representative of the entire student population at his school.

The favorite gaming app among the students on his teams may not be the same as the favorite gaming app among the broader student population.

To obtain a more accurate representation of the students' preferences, Rodell should aim for a random sample that includes students from various groups within the school, such as different grade levels or extracurricular activities.

This would help to minimize bias and ensure that the results reflect the overall preferences of the student body.

By solely relying on the football and basketball teams, Rodell's method limits the diversity of the sample, potentially leading to skewed results and an inaccurate conclusion about the favorite gaming app among all students at the school.

Therefore, Rodell's data collection method is flawed because it could lead to a biased sample, as it only includes students from his football and basketball teams.

To prove that a triangle is isosceles, we can use the distance formula to see if at least two sides are congruent.

To prove that a triangle is isosceles, we need to show that at least two sides of the triangle are congruent.

One way to do this is by using the distance formula. The distance formula is used to calculate the distance between two points in a coordinate plane. By calculating the distance between each pair of points that represent the vertices of the triangle, we can determine if any two sides have the same length. If we find that at least two sides have equal lengths, then we can conclude that the triangle is isosceles. Therefore, option (a) is the correct answer.

Using the slope formula to determine if any sides are perpendicular or parallel does not directly help in proving that a triangle is isosceles. Therefore, options (b) and (d) are not the correct answers.

Checking if all three sides are congruent using the distance formula is not necessary to prove that a triangle is isosceles. Therefore, option (c) is not the correct answer.

In conclusion, to prove that a triangle is isosceles, we can use the distance formula to see if at least two sides are congruent. This method provides a reliable and straightforward way to determine if a triangle is isosceles.

The mean weight loss of people on this drug, population mean, could be as low as 29 lbs  and if the study is repeated, the sample size should be at least 48 to achieve a margin of error less than 2 lbs.

(a) According to the information provided, the mean weight loss of people on this drug, population mean, could be as low as 29 lbs. This is calculated by subtracting the margin of error (±4 lbs) from the average weight loss (33 lbs): 33 - 4 = 29 lbs.

(b) To determine the required sample size for the study to be repeated with a margin of error less than 2 lbs, we can use the following formula for the margin of error (ME) with a known standard deviation (SD) and a confidence level (CL) of 95%:

ME = (1.96 * SD) / sqrt(n)

Here, ME = 2, SD = 7, and n is the sample size we need to find. Rearranging the formula to solve for n:

\(n = (1.96 * 7 / 2)^2\\n = (13.72 / 2)^2\\n = 6.86^2\)
n ≈ 47.1

Since we can't have a fraction of a sample, we round up to the nearest whole number. Therefore, if the study is repeated, the sample size should be at least 48 to achieve a margin of error less than 2 lbs.

69.7%

Step-by-step explanation:

The two positive numbers are x = 10 and y = 10.

Product of two numbers = 100

Let the first numbers be = x

Let the second number be = y

Any integer higher than zero is considered a positive number. Even natural numbers are included in its concept of numbers.

Therefore, according to the question -

xy = 100

y = 100/x

Thus, as two numbers are given,

f(x, y) = x + y

f(x) = x + 100/x

Now, minimum of f(x) is obtained at the point where f’(x) = 0

Therefore,

f’(x) = 1 - 100/x² = 0

x = ±10.

x = 10

Similarly,

y = 10
