Step-by-step explanation:

The area inside the curve r = 3 + sin(θ) is (5π)/2 square units.

Double integration is an important tool in calculus that allow us to calculate the area of irregular shapes in the Cartesian coordinate system. In particular, they are useful when we are dealing with shapes that are defined in polar coordinates.

To find the area inside this curve, we can use a double integral in polar coordinates. The general form of a double integral over a region R in the xy-plane is given by:

∬R f(x,y) dA

where dA represents the infinitesimal area element, and f(x,y) is the function that we want to integrate over the region R.

In polar coordinates, we can express dA as r dr dθ, where r is the distance from the origin to a point in the region R, and θ is the angle that this point makes with the positive x-axis. Using this expression, we can write the double integral in polar coordinates as:

∬R f(x,y) dA = ∫θ₁θ₂ ∫r₁r₂ f(r,θ) r dr dθ

where r₁ and r₂ are the minimum and maximum values of r over the region R, and θ₁ and θ₂ are the minimum and maximum values of θ.

To find the area inside the curve r = 3 + sin(θ), we can set f(r,θ) = 1, since we are interested in calculating the area and not some other function. The limits of integration can be determined by finding the values of r and θ that define the region enclosed by the curve.

To do this, we first note that the curve r = 3 + sin(θ) represents a cardioid, which is a type of curve that is symmetric about the x-axis. Therefore, we only need to consider the region in the first quadrant, where 0 ≤ θ ≤ π/2.

To find the limits of integration for r, we note that the curve intersects the x-axis when r = 0. Therefore, the minimum value of r is 0. The maximum value of r can be found by setting θ = π/2 and solving for r:

r = 3 + sin(π/2) = 4

Therefore, the limits of integration for r are r₁ = 0 and r₂ = 4.

The limits of integration for θ are simply θ₁ = 0 and θ₂ = π/2, since we are only considering the region in the first quadrant.

Putting it all together, we have:

Area = ∬R 1 dA

        = ∫[tex]0^{\pi /2}[/tex] ∫0⁴ 1 r dr dθ

Evaluating this integral gives us:

Area = π(3² - 2²)/2 = (5π)/2

Therefore, the area inside the curve r = 3 + sin(θ) is (5π)/2 square units.

Using double integrals, the area inside the curve r = 3 + sin(θ) is 0 units².

For the area inside the curve r = 3 + sin(θ), we can use a double integral in polar coordinates. The area can be expressed as:

A = ∬R r dr dθ

where R represents the region enclosed by the curve.

In this case, the curve r = 3 + sin(θ) represents a cardioid shape. To determine the limits of integration for r and θ, we need to find the bounds where the curve intersects.

To find the bounds for θ, we set the expression inside sin(θ) equal to zero:

3 + sin(θ) = 0

sin(θ) = -3

However, sin(θ) cannot be less than -1 or greater than 1. Therefore, there are no solutions for θ in this case.

Since there are no intersections, the region R is empty, and the area inside the curve r = 3 + sin(θ) is zero.

Hence, the area inside the curve r = 3 + sin(θ) is 0 units².

A domain is the set of all possible values that can be used as input for a function. In other words, it is the set of all numbers for which the function is defined.

For example, if we have a function that calculates the area of a circle given its radius, the domain of this function would be all positive real numbers, because a circle cannot have a negative radius or zero radius. Now, when we are asked to describe the domain of a function in exercises 1-3, we need to figure out what values of the independent variable (usually denoted by x) can be used as input for the function. We need to look for any restrictions on x that might cause the function to be undefined. These restrictions could be due to a variety of reasons, such as division by zero, taking the square root of a negative number, or simply having a certain range of values that make sense for the context of the problem.

In summary, describing the domain of a function involves identifying the set of all possible input values that make sense for the function to be applied. It is an important concept in mathematics and is used in many different areas, from calculus to statistics.
In Exercises 1-3, the domain of the function refers to the set of all possible input values (independent variable) for which the function is defined. To describe the domain, you would need to identify the valid range of inputs for the given function in each exercise. For example, if a function has a square root or a denominator, the domain would exclude values that result in undefined outputs (like negative values under the square root or a zero in the denominator). Once you determine the domain for each exercise, you can express it using interval notation or inequalities to represent the allowable input values for the function in question.

Thus, the limit is the definition of the definite integral ∫8^4 x/(x^3) dx, expressed as a limit of Riemann sums with right endpoints.

To express the integral ∫8^4 x/(x^3) dx as a limit of Riemann sums, we first need to partition the interval [4,8] into n subintervals of equal width Δx = (8-4)/n.

Let xi be the right endpoint of the ith subinterval, so xi = 4 + iΔx.

Then, the Riemann sum with right endpoints is:
∑(i=1 to n) f(xi)Δx

where f(xi) is the value of the function x/(x^3) at xi.

Substituting xi = 4 + iΔx and f(xi) = xi/(xi^3), we get:
∑(i=1 to n) (4+iΔx)/(4+i^3Δx^3) Δx

This is the expression for the Riemann sum with right endpoints.

To express the integral as a limit of Riemann sums, we take the limit of this expression as n goes to infinity:
lim(n->∞) ∑(i=1 to n) (4+iΔx)/(4+i^3Δx^3) Δx

a_1 = -2

a_2 = 1

a_3 = -4/2 = -2

a_4 = 7/3

As we can see, the sequence does not consistently increase or decrease as n increases.

To determine if the sequence is bounded, we can look at the limit of the sequence as n approaches infinity. We have:

lim (n -> infinity) (n^2 - 3) / (n + 1)

= lim (n -> infinity) (1 - 3/n^2) / (1 + 1/n)

In this case, the probability of rolling a 3 on the first roll is 1/6, and the probability of rolling a 3 on the second roll is also 1/6, since the rolls are independent of each other. Therefore, the probability of both events occurring (rolling a 3 on both rolls) is:

P(A ∩ B) = P(A) x P(B)
P(A ∩ B) = (1/6) x (1/6)
P(A ∩ B) = 1/36

So the probability of rolling a 3 on both rolls is 1/36.

In explanation, when events are independent, the probability of both events occurring is found by multiplying their individual probabilities. This is because the outcome of one event does not affect the outcome of the other event.

After the first discount of 12%, a further 20% discount is given, which means the new price becomes:

P'' = P'(1 - 0.20) = 0.88P(0.80) = 0.704P

We are also given that the new price is $281.6, so we can set up an equation and solve for P:

0.704P = 281.6

P = 400
