To findThe curve r = 1 - sin(θ) represents a cardioid shape. It has a single petal that extends from θ = 0 to θ = π. Since we want to find the area below the polar axis, we only need to consider the region where r is negative.

the definite integral that represents the area of the region below the polar axis and enclosed by the polar curve r = 1 - sin(θ), we need to determine the limits of integration and the integrand.

The polar curve r = 1 - sin(θ) represents a cardioid shape. To find the area below the polar axis, we need to integrate the function from the starting angle to the ending angle, considering only the negative values of r.

In this case, the cardioid is symmetric about the x-axis, so we can integrate from θ = -π/2 to θ = π/2 to cover the complete area below the polar axis.

The integrand is the negative value of the polar curve, as we are interested in the area below the polar axis:

Using mathematical operations, we know that the drop in temperature in each hour is 2°C, and the operations which represent this is 10/5 = 2°C.

Calculating a value using operands and a math operator is referred to as performing a mathematical "operation."

The math operator's symbol has predetermined rules that must be applied to the supplied operands or numbers.

In mathematics, addition, subtraction, multiplication, division, and modular forms are the five basic operations.

So, the operation that represents the change in temperature:

Time taken is 5 hours.

The temperature drop is 10°C.

The same amount of temperature in each hour.

Then, the operation will be:

10/5 = 2°C

Therefore, using mathematical operations, we know that the drop in temperature in each hour is 2°C, and the operation which represents this is 10/5 = 2°C.

The point on the ellipse that is farthest from the origin will be the point that is closest to one of the foci.

To find the points on the ellipse that are nearest to and farthest from the origin, we need to consider the equation of the paraboloid and the equation of the ellipse.

The equation of a paraboloid is given by:

\(z = ax^2 + by^2 + c\)

where a, b, and c are constants.

The equation of an ellipse is given by:

\((\frac{x}{a})^2 + (\frac{y}{b})^2 = 1\)

where a and b are the semi-major and semi-minor axes of the ellipse, respectively.

If the plane intersects the paraboloid in an ellipse, then the equations of the paraboloid and the ellipse must be equal at the points of intersection. Therefore, we can set the equation of the paraboloid equal to the equation of the ellipse and solve for the x and y values.

\(z = ax^2 + by^2 + c\)

\((\frac{x}{a})^2 + (\frac{y}{b})^2 = 1\)

Substituting the equation of the paraboloid into the equation of the ellipse, we get:

\((\frac{x}{a})^2 + (\frac{y}{b})^2+c = 1\)

We can then solve this equation for the values of x and y that correspond to the points on the ellipse that are nearest to and farthest from the origin.

The point farthest away from the origin occurs at the point on the ellipse that is farthest from the center, which is called the "foci" of the ellipse. The distance from the center of the ellipse to the foci is called the "eccentricity" of the ellipse. The eccentricity is denoted by the letter "e" and is calculated using the following formula:

\(e = \frac{\sqrt{(a^2 - b^2)}}{a}\)

where a and b are the semi-major and semi-minor axes of the ellipse, respectively.

Therefore, to find the point on the ellipse that is farthest from the origin, we need to calculate the eccentricity of the ellipse and then use this value to determine the location of the foci. The point on the ellipse that is farthest from the origin will be the point that is closest to one of the foci.

Michael needs to analyze the population data, demographics of the city, and the competition in the area to determine whether or not to open a new store.

Michael is trying to determine where to open two new store locations. He has population data to determine the amount of revenue he will receive for each location.

He is charged a $1000 fee for opening a new store at a certain location. However, he is unsure whether the population of the city would be large enough to warrant opening a new store at that location.

The first step that Michael needs to take is to analyze the population data that he has.

Based on the population data, he needs to make an informed decision about whether or not to open a new store at that location. This would require him to take into consideration the average income of the population as well as the demographics of the city.

Another important factor that Michael needs to take into consideration is the competition in the area. If there are already several stores in the area, then opening a new store might not be a good idea.

This is because the competition would be too high and he would not be able to generate enough revenue to make up for the cost of opening a new store.

However, if there are no stores in the area, then Michael might consider opening a new store. This would require him to invest a significant amount of money, but he could also generate a significant amount of revenue in return.

Additionally, he needs to take into consideration the cost of opening a new store and whether or not he can generate enough revenue to make up for that cost.

Overall, Michael needs to carefully analyze all the data that he has before making an informed decision about where to open new store locations.

In conclusion, Michael needs to analyze the population data, demographics of the city, and the competition in the area to determine whether or not to open a new store. If the population is large enough and there is no competition in the area, then he should consider opening a new store. However, if there is already a significant amount of competition in the area, then he should avoid opening a new store.

Then total game won = 6+x

total game lost = 4

win: loss = 6+x : 4

given ratio of win and loss = 2:1

6+x : 4 = 2: 1

6+x = 8

The probability that a randomly selected coffee drinker does not use sugar or cream is \(1 - p^2.\)

To find the probability that a randomly selected coffee drinker does not use sugar or cream, we need to find the probability of the complement of the event (C or S).

That is, we need to find the probability of the coffee drinker not using cream and not using sugar.
We can use the formula P(not C and not S) = P(not C) * P(not S|not C),

where P(not C) is the probability of not using cream and P(not S|not C) is the conditional probability of not using sugar given that the coffee drinker does not use cream.
Since we do not have any information about the probabilities of using cream and sugar, we cannot find the exact probabilities.

However, we can assume that the probabilities are equal and use the complement rule, which states that P(not C or not S) = 1 - P(C and S).
Since we do not have any information about the joint probability of using cream and sugar, we can assume that the events C and S are independent. Therefore, P(C and S) = P(C) * P(S).
Assuming that P(C) = P(S) = p, we have P(not C or not S) = 1 - P(C and S) \(= 1 - p^2\)

f(x) = 9x^2

y = 9x^2

x = 9y^2

\(\sqrt{\frac{x}{9} }\) = y

y = √x/3 or -√x/3

Answer:

The inverse of the function f(x) = 9x^2 is f^-1(x) = sqrt(x/9). To obtain the inverse, replace f(x) with y, solve for x in terms of y, and replace x with f^-1(x).

Step-by-step explanation:

To find the inverse of the function f(x) = 9x^2, we can follow these steps:

y = 9x^2

y/9 = x^2

±sqrt(y/9) = x

Note that we include both positive and negative square roots, but since x ≥ 0 in the domain of the original function, we only take the positive square root.

f^-1(x) = sqrt(x/9)

Therefore, the inverse of the function f(x) = 9x^2 is f^-1(x) = sqrt(x/9).

The value of the postfix expression 32 * 2 | 53 - 84/ * is 15.

Here's how to solve it:

1. Start from the left and work towards the right.
2. Multiply 32 and 2 to get 64.
3. Use the bitwise OR operator (|) on 64 and 53. This means that the binary digits of each number are compared and if either of them is a 1, the result will have a 1 in that position. In this case, 64 is 1000000 in binary and 53 is 110101 in binary. When we use the bitwise OR operator, we get 1001101, which is 77 in decimal.
4. Subtract 77 from 53 to get -24.
5. Divide 84 by -24 to get -3.5.
6. Finally, multiply -3.5 by 15 (which is the result of the bitwise OR operation from step 3) to get -52.5.

So, the value of the postfix expression is -52.5, which rounds up to -53, or 15 when the absolute value is taken. Therefore, the correct answer is d. 15.

The change is negative, indicating a reduction in the consumer's consumption of good y after the introduction of the tax. Therefore, the answer is -9.7140.

The optimal consumption of good y before the introduction of tax (y*) is obtained by maximizing the utility function under the budget constraint, i.e., px​x+py​y=m. Thus, the problem is: max(A+Bxᵅyᵝ)ᶜ st px​x+py​y=m.

The Lagrangian is: L=(A+Bxᵅyᵝ)ᶜ+λ(m−px​x−py​y),

The FOCs are:

∂L/∂x=0

=CB(A+Bxᵅyᵝ)ᶜ−λpx​∂L/∂y=0

=CB(A+Bxᵅyᵝ)ᶜ−λpy​px​x+py​y=m.

We can solve for x and y to obtain:

x=(Bpy​)^(−1/α)∗((CB(m/px​))^(1/α))

y=((Bpx​)^(−1/β)∗((CB(m/py​))^(1/β)), respectively.

Using the parameter values given in the question, we get: x=7.7088 and y=22.4589, which is the optimal consumption of good y before the tax is introduced. After the tax is introduced, the budget constraint becomes: px​x+(1+τ)py​y=m, where τ is the ad valorem tax rate, i.e., τ=0.607.

Using the same method as above, the optimal consumption of good y after the tax is introduced (y**) is:

y**=((Bpx​)^(−1/β)∗((CB(m/(1+τ)py​))^(1/β)), which gives us y**=12.7449.

Thus, the change in the consumer's consumption of good y is:

Δy=y**−y*

=12.7449−22.4589
