The discount amount is $331.80. The price after discount is $616.20. The sales tax amount is $56.63. The final price is $672.83.

A TV originally priced at $948 is on sale for 35% off. We are to find the discount amount and the price after discount.

The original price of the TV = $948

The percentage discount = 35%.

Let X be the price after discount.

We can find X as follows:

Discount = 35% of original price

= 35% of 948= (35/100) × 948= $331.80

Price after discount (X) = Original price - Discount

= $948 - $331.80= $616.20

Therefore, the price after discount is $616.20.

Now we are to find the tax amount and the final price after including the discount and sales tax.

The sales tax is 9.2%.

We can find the tax amount as follows:

Tax amount = 9.2% of price after discount

= 9.2% of $616.20= (9.2/100) × 616.20= $56.63

Now, the final price after including the discount and sales tax = Price after discount + Tax amount

= $616.20 + $56.63= $672.83

Therefore, the final price after including the discount and sales tax is $672.83.

To calculate the given volume integral, 4(x^3 + xy^2) dV, over the solid E in the first octant beneath the paraboloid z = 1 - x^2 - y^2, we need to set up the integral in cylindrical coordinates. The integral will involve integrating over the appropriate limits and applying the volume element in cylindrical coordinates.

In cylindrical coordinates, we have x = r cos θ, y = r sin θ, and z = z.
The equation of the paraboloid, z = 1 - x^2 - y^2, can be expressed as z = 1 - r^2.
The given volume integral becomes 4(x^3 + xy^2) dV = 4(r^3 cos^3 θ + r^3 cos θ sin^2 θ) r dz dr dθ.
To determine the limits of integration, we need to consider the region of the solid E in the first octant. Since the solid lies beneath the paraboloid z = 1 - x^2 - y^2, the upper limit for z is given by z = 1 - r^2.
The limits for r and θ depend on the region in the first octant. We need to set appropriate limits to cover the desired region.Once we have the limits for r, θ, and z, we can set up the triple integral using the volume element in cylindrical coordinates.
By evaluating the integral with the corresponding limits, we can find the value of the given volume integral over the solid E in the first octant beneath the paraboloid.

            (4)(7) ____ 7

                28     >   7

Answer:

B

Step-by-step explanation:

a is a cubic. A cubic is an equation that has 3 on its base x to become x^3 as it's highest power. That is not a quadratic. A cubic and a quadratic are not the same thing.

b is a quadratic The highest power is 2 on the base (x)  to become x^2. That is how a quadratic is defined.

c is a reciprocal. It has its highest power in the denominator, and that is not a quadratic. A quadratic is an equation whose highest power is 2 on its base (x) and whose highest power is in the numerator, not the denominator. This choice is rather tricky because the quadratic formula can be used on it if you change x = 1/z. Then the equation becomes f(x) = 4z^2 - 2z + 1. But as it is given and likely as you have been told, this is not a quadratic. This will factor into  (2z - 1)(2z - 1). If I were a student, I'd question this one. It would be interesting to see how your instructor would eliminate it.

d is just a linear function. Since x^2 is multiplied by 0, it disappears. What is left is f(x) = -9x + 7 which is a linear function.

The perimeter of the shape is approximately 44.00 feet, and the area is approximately 160.50 square feet.

To determine the perimeter of the shape, we add up the lengths of all its sides. The given sides are 4 ft, 16.5 ft, 4 ft, and 20 ft. Adding these lengths together, we get a perimeter of 44.5 ft. However, since we are asked to round to the nearest hundredth, the perimeter becomes approximately 44.00 feet.

To find the area of the shape, we need to know its specific shape. Since the given measurements do not provide enough information, it is not possible to accurately determine the area. In order to calculate the area, we need to know the shape's dimensions, angles, or additional side lengths. Without this information, we cannot determine the area accurately.

In conclusion, the perimeter of the shape is approximately 44.00 feet, but the area cannot be determined without further information.

Edge set of the graph with vertices F, G, H, I, J, K, and L that has an Euler trail, the degree of I is 1 and the degree of K is 3 is: {(F, H), (G, H), (G, I), (H, J), (I, K), (J, K), (K, L), (K, F)}.

To construct a simple graph with vertices F, G, H, I, J, K, L that has an Euler trail, the degree of I is 1 and the degree of K is 3 and the corresponding edge set, we can follow this method

1: Draw the vertices of the graph. We have 7 vertices, F, G, H, I, J, K, and L.

2: Draw edges between the vertices to form the graph. Since the degree of I is 1 and the degree of K is 3, we can connect I to some other vertex and K to three other vertices.

3: Check if the graph has an Euler trail. A graph has an Euler trail if all vertices have an even degree or if exactly two vertices have an odd degree. Here, the degree of I is 1 and the degree of K is 3, so the graph has two vertices with odd degrees. Therefore, the graph has an Euler trail.

4: Write down the edge set. The edge set of the graph can be written as follows: {(F, H), (G, H), (G, I), (H, J), (I, K), (J, K), (K, L), (K, F)}

In the given circuit, there are two resistors, R1 and R2, both with a resistance of 4 Ω. The circuit analysis and determination of various electrical quantities, such as current and voltage, can be performed based on this information.

The circuit consists of two resistors, R1 and R2, each with a resistance of 4 Ω. To analyze the circuit and determine various electrical quantities, we can apply principles such as Ohm's law and Kirchhoff's laws.

Firstly, we can calculate the total resistance in the circuit by combining the resistors in series or parallel based on their connection. If R1 and R2 are in series, their total resistance, RT, would be the sum of their individual resistances, i.e., RT = R1 + R2 = 8 Ω.

Once we know the total resistance, we can use Ohm's law (V = IR) to calculate the voltage across the resistors or the current flowing through them. If the circuit is connected to a power source or a given voltage, we can determine the current flowing through the resistors using Ohm's law and Kirchhoff's laws.

The maximum number of ways for all these players to play in the given scenario is 12.

To determine the maximum number of ways for the players to play, we can consider the possible match-ups between the players. Since a player always plays with the nearest rank player who is still in the competition, we can start with the highest-ranked player (#1) and pair them with the next nearest player in rank (#2). This creates one match. Then, the remaining players (#3, #4, and #5) can be paired in different ways: (3, 4), (4, 5), and (3, 5). This results in three more matches. Therefore, in total, we have four matches.

For each match, the winner moves on to the next round, while the loser is eliminated. Following this process, we can have a maximum of three rounds of matches, resulting in a total of 12 possible ways for all the players to play.

C.) The vertex is at (2, 8) and the axis of symmetry is x = 2.

Step-by-step explanation:

I got a 100 on edge

The vertex is at (2,8) and the axis of symmetry is x = 2

The vertex of a curve is the point where the curve passes its axis of symmetry. While the axis of symmetry is the line that divides the curve into two equal halves.

Analysis:

if y = a[tex]x^{2}[/tex]+bx +c.  then the axis of symmetry occurs at  [tex]\frac{-b}{2a}[/tex] and the vertex occurs at [tex]\frac{-b}{2a}[/tex] and the value of y at [tex]\frac{-b}{2a}[/tex].

comparing the above with the equation h(x) = -2[tex]x^{2}[/tex]+8x

x coordinate for vertex = [tex]\frac{-8}{2 x -2}[/tex]  = 2

y coordinate at x = 2

-2[tex](2)^{2}[/tex] + 8(2) = 8

vertex is at point (2,8)

axis of symmetry is the x coordinate of the vertex which is at x = 2

Answer:

Not sure what you mean by "all". If you literally meant all the ratios that are equivalent to 75:50, the answer would be basically infinite. Maybe you mean in simplest terms, which is most commonly answered. In that case, the answer is 3:2

The correct answer is: 0, -3, and 3. At  0, -3, and 3 of x does fx) x4-18x2 have a critical point where the graph changes from decreasing to increasing.

To find the critical points where the graph of the function f(x) = x^4 - 18x^2 changes from decreasing to increasing, we need to find the values of x where the derivative of the function is equal to zero or does not exist.

Let's find the derivative of f(x) with respect to x:

f'(x) = 4x^3 - 36x

To find the critical points, we set the derivative equal to zero and solve for x:

4x^3 - 36x = 0

Factor out 4x:

4x(x^2 - 9) = 0

Now we have two factors:

1) 4x = 0, which gives x = 0

2) x^2 - 9 = 0, which gives x = ±3

So, the critical points where the graph changes from decreasing to increasing are x = 0, x = -3, and x = 3.

Therefore, the correct answer is: 0, -3, and 3.

D: 121

Step-by-step explanation:

Step One: To do this problem, you must understand the rule that all angles in a triangle add up to 180 degrees.

Step Two: Now that we know the rule, we know this triangle equals 180 degrees. First, we must add the angles we DO know together: 26+33= 59.  

Step Three: We can subtract 59 from 180 to find the missing angle: 180-59= 121.

The equivalent double integral in polar coordinates is: 1 = ∫∫(2 - r²cosθ) rdr dθ.

In polar coordinates, we can express the given double integral as 1 = ∫∫(2 - r²cosθ) rdr dθ. To convert from rectangular coordinates to polar coordinates, we substitute x = rcosθ and y = rsinθ. The element of area in polar coordinates is given by dA = rdr dθ.

By making these substitutions and adjusting the limits of integration accordingly, we obtain the equivalent double integral in polar coordinates.

The integral becomes 1 = ∫∫(2 - r²cosθ) rdr dθ. This form allows us to integrate with respect to r first and then with respect to θ, simplifying the evaluation process.

Polar coordinates provide an alternative way to express integrals, particularly when dealing with problems involving circular or radial symmetry.

They use the distance from a fixed point (the origin) and the angle measured from a reference direction (usually the positive x-axis) to represent points in the plane.
