Thus, the integral of [(ln(x))² + x³] .dx is:  ∫[(ln(x))² + x³] .dx = x(ln(x))² - x²/2 + (1/4)x⁴ + C

To evaluate the integral of [(ln(x))² + x³] .dx, we need to integrate each term separately.

The integral of (ln(x))² can be found using integration by parts:

Let u = ln(x) and dv = ln(x) dx. Then du = 1/x dx and v = x ln(x) - x.

Using the formula for integration by parts, we have:
∫(ln(x))² dx = u*v - ∫v*du
= ln(x) * [x ln(x) - x] - ∫(x ln(x) - x) * (1/x) dx
= x(ln(x))² - x²/2 + C

where C is the constant of integration.

Next, the integral of x³ is a simple power rule integration:
∫x³ dx = (1/4)x⁴ + C
where C is the constant of integration.

Therefore, the integral of [(ln(x))² + x³] .dx is:
∫[(ln(x))² + x³] .dx = x(ln(x))² - x²/2 + (1/4)x⁴ + C
where C is the constant of integration.

To provide a solution for this problem, we can factor the polynomial or find its roots using the rational root theorem.

One possible factorization of the polynomial is:

3x^3 + 13x^2 + 18x - 12 = (x+1)(3x^2 + 10x - 12)

To obtain this factorization, we can start by trying factors of the constant term -12 that might work as roots of the polynomial.

One such factor is -1, so we can use synthetic division or long division to divide the polynomial by x+1. This gives us a quotient of 3x^2 + 10x - 12, which can be factored using the quadratic formula or other methods.

The roots of the polynomial can be found by setting each factor equal to zero and solving for x. This gives us:

x+1 = 0 or 3x^2 + 10x - 12 = 0

The first equation has a single root of x = -1. The second equation can be solved using the quadratic formula or factoring, giving us two more roots:

x = (-10 ± sqrt(100 + 4312)) / (2*3) = (-10 ± 2sqrt(19)) / 3

Therefore, the roots of the polynomial are -1, (-10 + 2sqrt(19))/3, and (-10 - 2sqrt(19))/3.

the line segment after a 90 counterclockwise rotation about the origin is attached accordingly.

A rotation is a sort of transformation  that rotates each point in a figure a specific number of degrees around a particular  point.

To do a 90-  degree counterclockwise rotation about  the origin, we can use the following rotation  formula

x ' = x *  cos( θ) - y * sin(θ)

 y' =  x * sin(θ )+ y * cos( θ)

where   (x, y) are the original coordinates and (x ', y') are the coordinates after the rotation.

Applying this

For   point A (- 5, -3) we have

x' = (-5) * cos(90°) - ( -3) * sin(90 °) = 3

y' = (-5) * sin(90°)+ (-3) * cos(90°) =  -5

So the new coordinates after the 90-degree counterclockwise rotation about the origin for point A are (3, -5).

 point B (1  , -2)

x' =  (1 ) * cos(90°) - (-2) * sin(90°) = 2

y ' = (1 ) * sin ( 90°) + ( - 2) * cos (90 °) = 1

So the new coordinates after the 90-degree counterclockwise rotation about the origin   for point B are (2, 1).

The line segment after a 90-degree counterclockwise rotation about the origin would connect point A' (3, -5) to point B' (2, 1).

The list price of the HDTV with a 25% trade discount rate can be calculated as approximately $1733.33, based on the given net price of $1300.



Let's assume the list price of the HDTV is L dollars. The trade discount rate is 25%, which means the customer gets a 25% reduction on the list price.

The trade discount can be calculated by multiplying the list price (L) by the discount rate (25% = 0.25): Discount = 0.25L

The net price is the list price minus the trade discount, so we have: Net Price = L - Discount

Given that the net price is $1300, we can substitute the values into the equation: 1300 = L - 0.25L

Combining like terms, we get: 1300 = 0.75L

Dividing both sides of the equation by 0.75, we find: L = 1300 / 0.75 = $1733.33

Therefore, the list price of the HDTV is approximately $1733.33.

True. fi and f2 are both real-valued and both injective and surjective functions with the same domain, then f1 + f2 is invertible.

Let g = f1 + f2. To prove that g is invertible, we need to show that g is both injective and surjective.

Injectivity: Suppose that g(x) = g(y). Then, we have f1(x) + f2(x) = f1(y) + f2(y), which implies that f1(x) - f1(y) = f2(y) - f2(x). Since f1 and f2 are injective, it follows that x = y. Thus, g is injective.

Surjectivity: Let z be an arbitrary element in the codomain of g. Since f1 and f2 are surjective, there exist elements x and y in the domain of g such that f1(x) = z - f2(y). Then, we have g(x) = f1(x) + f2(x) = z - f2(y) + f2(x) = z + (f2(x) - f2(y)). Since f2 is surjective, there exists an element w in the domain of g such that f2(w) = f2(x) - f2(y). Then, we have g(w) = z, which implies that g is surjective.

The Federal Reserve can only set a money supply target that is consistent with a nominal interest rate target and vice versa. The correct answer is C).

The Federal Reserve has the ability to set targets for both the money supply and the nominal interest rate, but it cannot do so independently. In other words, the two targets are interdependent and setting one requires consideration of the other.

The Federal Reserve can adjust the money supply through open market operations, which involve buying or selling government securities to increase or decrease the money supply respectively. Adjusting the money supply affects interest rates through the supply and demand for loans. If the money supply increases, interest rates will decrease, and vice versa.

Therefore, the Federal Reserve must consider both targets when making policy decisions. Ultimately, the goal of the Federal Reserve is to maintain stable economic growth and price stability, which requires careful consideration of both the money supply and the nominal interest rate.

According to the question we have the radius of the sphere is 5 inches.

To find the radius of a sphere given its volume, we can use the formula:

V = (4/3)πr³

where V is the volume of the sphere and r is its radius. We are given that the volume of the sphere is:

V = 500π/3 cubic inches

Substituting this value into the formula, we get:

500π/3 = (4/3)πr³

Multiplying both sides by 3/4π, we get:

r³ = (500/4)

Simplifying, we get:

r³ = 125

Taking the cube root of both sides, we get:

r = 5

1. Divide both sides by π:
(500/3) = (4/3)r³

2. Multiply both sides by 3 to remove the fraction:
500 = 4r³

125 = r³

The relative importance of unique events may decrease as the probability of a super event increases, it is important to consider all potential risks and their unique characteristics in a comprehensive approach to risk management.

The relationship between the probability of a super event and the importance of a unique event is complex and depends on several factors. Generally speaking, as the probability of a super event increases, the importance of a unique event may decrease in relative importance.

This is because the focus shifts from rare events to more probable ones. As the probability of a super event increases, there may be a greater need to allocate resources toward preventing or mitigating the effects of such events. This can mean that resources that were previously allocated to mitigating the risks of unique events may be redirected towards addressing the more significant risk posed by the super event.

However, it is important to note that the importance of unique events should not be overlooked or underestimated. These events may still pose significant risks and may require specific measures to prevent or mitigate their effects.

The area of the surface obtained by rotating the curve y = (x³/6) + (1/2x) from 1/2 to 1 about the x-axis is given by the above expression is 2π (1/6 x √(1+ 9x² - 3x⁴/4)).

Calculate the arc length of the curve

We first need to calculate the arc length of the curve, which can be done using the formula:

L = ∫aᵇ √(1+ (dy/dx)²) dx

where,

dy/dx = (3x² - 1/2x²)/6

Therefore, the arc length of the curve is given by:

L = ∫1/2¹√(1+ (3x² - 1/2x² )/6)dx

Calculate the area of the surface

Once we have the arc length of the curve, we can calculate the area of the surface obtained by rotating the curve about the x-axis. This can be done using the formula:

A = 2π × L

Substituting the arc length of the curve in the formula, we get:

A = 2π × ∫1/2¹√(1+ (3x² - 1/2x²)/6)dx

Evaluate the integral

Finally, we need to evaluate the integral in order to calculate the area of the surface. We can do this using integration by parts, which gives us:

A = 2π × ∫1/2¹√(1+ (3x² - 1/2x²)/6)dx

= 2π (1/6 x √(1+ 9x² - 3x⁴/4) - (1/6) ∫1/2¹ (9x² - 3x⁴/4)/√(1+ 9x² - 3x⁴4) dx)
