Answer:

none of the above

Step-by-step explanation:

3(x − 4)² +6 = 0

3(x − 4)² = -6 / : 3

(x − 4)² = -2

x² - 8x + 16 = -2

x² - 8x + 16 + 2 = 0

x² - 8x + 18 = 0

D = b² - 4ac = (-8)² - 4 * 1 * 18 = 64 - 72 = -8 < 0

Since the discriminant is less than zero, this quadratic equation has no solutions, the graph would not cross the x-axis and therefore have no zeros.

The volume enclosed by the two curves when revolved about the x-axis is \(\(\frac{6\pi}{5} \ln 3 - \frac{3\pi}{2} \cdot 3^{\frac{4}{5}}\).\) To find the volume when the area enclosed by the graphs of \(\(y = x^2\)\)and \(\(y = \frac{3}{x^3}\)\) is revolved about the x-axis, we can use the method of cylindrical shells.

First, let's find the points of intersection between the two curves by setting them equal to each other:

\(\[x^2 = \frac{3}{x^3}\]\)

To simplify this equation, we can multiply both sides by \(\(x^3\)\):

\(\[x^5 = 3\]\)

Now, taking the fifth root of both sides:

\(\[x = \sqrt[5]{3}\]\)

So the two curves intersect at \(\(x = \sqrt[5]{3}\)\).

To calculate the volume area enclosed by the graphs of \(\(y = x^2\)\)and \(\(y = \frac{3}{x^3}\)\) is revolved about the x-axis, we need to integrate the circumference of each cylindrical shell multiplied by its height. The height of each shell is the difference in the y-values of the two curves, and the circumference is\(\(2\pi x\)\).

Let's integrate from \(\(x = 0\)\) to \(\(x = \sqrt[5]{3}\)\):

\(\[V = \int_0^{\sqrt[5]{3}} 2\pi x \left(\frac{3}{x^3} - x^2\right) \, dx\]\)

Simplifying this expression:

\(\[V = 2\pi \int_0^{\sqrt[5]{3}} \left(\frac{3}{x} - x^3\right) \, dx\]\)

Integrating each term separately:

\(\[V = 2\pi \left[3 \ln|x| - \frac{x^4}{4}\right]_0^{\sqrt[5]{3}}\]\)

Plugging in the limits of integration:

\(\[V = 2\pi \left[3 \ln|\sqrt[5]{3}| - \frac{\sqrt[5]{3}^4}{4}\right] - 2\pi \left[3 \ln|0| - \frac{0^4}{4}\right]\]\)

Since \(\(\ln|0|\)\)is undefined, the second term on the right side is zero:

\(\[V = 2\pi \left[3 \ln|\sqrt[5]{3}| - \frac{\sqrt[5]{3}^4}{4}\right]\]\)

Simplifying further:

\(\[V = 2\pi \left[3 \ln 3^{\frac{1}{5}} - \frac{3}{4} \cdot 3^{\frac{4}{5}}\right]\]\)

Using the properties of logarithms, we can simplify the first term:

\(\[V = 2\pi \left[3 \cdot \frac{1}{5} \ln 3 - \frac{3}{4} \cdot 3^{\frac{4}{5}}\right]\]\)

\(\[V = \frac{6\pi}{5} \ln 3 - \frac{3\pi}{2} \cdot 3^{\frac{4}{5}}\]\)

So the volume enclosed by the two curves when revolved about the x-axis is \(\(\frac{6\pi}{5} \ln 3 - \frac{3\pi}{2} \cdot 3^{\frac{4}{5}}\).\)

Answer:

-2.23007452E187.

Step-by-step explanation:

Podemos empezar con (2x^ 3y^ 2z) / 3.

x = -2; y = 3; z = 4

2x^3y^2z = (2 * (-2))^ (3 * 3)^ (2 * 4) = (-4)^ 9^ 8 = (-262,144)^ 8 = 22,300,745,200,000,000,000,000,000,000,000,000,000,000,000, que es 2.23007452E43.

2.23007452E43 / 3 = 7.433581733E42.

Segundo, podemos hacer 10x^ 2y^ 3z^ 2.

10x^ 2y^ 3z^ 2 = (10 * (-2))^ (2 * 3)^ (3 * 4)^ 2 = (-20)^ (6)^ (12)^ 2 = 64,000,000^ 12 ^ 2 = 4.722366483E93^ 2 = 2.23007452E187.

Para terminar el problema, lo pondremos todo junto.

7.433581733E42 - 2.23007452E187 + 12 = -2.23007452E187.

To determine if the given points are part of the (200) plane, we need to check if their coordinates satisfy the equation of the plane.

The equation of a plane in three-dimensional space is typically written in the form Ax + By + Cz + D = 0, where A, B, C, and D are constants. For the (200) plane, the equation would be 2x + 0y + 0z + 0 = 0, which simplifies to 2x = 0. Let's check the given points: a) (1/2, 0, 0): When we substitute x = 1/2 into the equation 2x = 0, we get 2(1/2) = 0, which is true. Therefore, point a) lies on the (200) plane. b) (-1/3, 0, 0): Substituting x = -1/3 into the equation 2x = 0 gives us 2(-1/3) = 0, which is also true. So, point b) is part of the (200) plane. c) (0, 1, 0):When we substitute x = 0 into the equation 2x = 0, we get 2(0) = 0, which is true. Thus, point c) lies on the (200) plane. All three given points (a), b), and c)) are part of the (200) plane.

In conclusion, all three given points (a), b), and c)) are part of the (200) plane.

From the given graph we can see that the graphical representation of the function has an open dot on -1. Hence, the function has no solution for f(-1).

An open dot on a number line graph denotes that the given number cannot be a solution, whereas a solid dot on the graph suggests that the supplied number should be considered as a potential solution. For instance, if you graph x > 7, you would put an open dot there because that is not a correct response (7 is not greater than itself).

Now that we have the surface area of the door, Stephanie can determine if she has enough paint to cover it.

To find the surface area of Stephanie's door, we need to calculate the area of each face of the door and then add them together. Let's assume that the door is rectangular.

1. Measure the length, width, and height of the door. Let's say the length is 80 inches, the width is 200 inches, and the height is 3 inches.

2. To find the area of the front and back faces of the door, multiply the length by the height. In this case, the area of each face is 80 inches * 3 inches = 240 square inches.

3. To find the area of the top and bottom faces of the door, multiply the width by the length. In this case, the area of each face is 200 inches * 80 inches = 16,000 square inches.

4. To find the area of the two side faces of the door, multiply the width by the height. In this case, the area of each face is 200 inches * 3 inches = 600 square inches.

5. Now, add up all the areas of the faces to get the total surface area of the door. In this case, 240 square inches + 240 square inches + 16,000 square inches + 16,000 square inches + 600 square inches + 600 square inches = 33,680 square inches.

The correct option is (b) sample size.

In the formula for calculating the standard deviation, the letter n represent  sample size.

What is standard deviation?

Standard deviation is a statistical standard measure in finance that, when applied to an investment's annual rate of return, sheds light on its historical volatility.

Some key features regarding the standard deviation are-

A square root of a value deduced from correlating data points to a population's collective mean is used to calculate standard deviation. The formula is:

Standard Deviation = \(\sqrt{\frac{summation n to i=1 (x_{i}-bar x )}{n-1} }\)

Where,

\(x_{i}\)= value of the i th point the the given data set.

\(barx\)= mean value

n = total number of data points.

By reflecting the plane over the perpendicular bisector line ℓ, we can prove the Perpendicular Bisector Theorem.

The Perpendicular Bisector Theorem states that if a point lies on the perpendicular bisector of a segment, then it is equidistant from the endpoints of that segment.

In the given scenario, line ℓ is the perpendicular bisector of segment \overline{km}. When we reflect the plane over line ℓ, the image of point n (denoted as n') will be equidistant from points k and m. This is because the reflection preserves distances, and the perpendicular bisector line ℓ ensures that the distances from n' to k and m are equal.

Therefore, by reflecting the plane over line ℓ, we can visually demonstrate and prove the Perpendicular Bisector Theorem.

Reflecting the plane over the perpendicular bisector line ℓ allows us to prove the Perpendicular Bisector Theorem, which states that a point lying on the perpendicular bisector of a segment is equidistant from the endpoints of that segment.

10m3n2 and 15mn4 could have a greatest common factor  of 5m2n2.

Two terms that could have a greatest common factor of 5m2n2 are 10m3n2 and 15mn4.

To see why, we can factor each term into its prime factors and then identify the factors that are common to both terms.

First, let's factor 10m3n2:
10m3n2 = 2 × 5 × m × m × m × n × n

Next, let's factor 15mn4:
15mn4 = 3 × 5 × m × n × n × n × n

Now, we can identify the factors that are common to both terms:
- 5
- m
- n
- n

These common factors can be combined to give the greatest common factor of the two terms:
5m2n2

Therefore, 10m3n2 and 15mn4 could have a greatest common factor of 5m2n2.

It's worth noting that there could be other pairs of terms that also have a greatest common factor of 5m2n2, but this is just one example. To find other pairs, we would need to factor the terms and look for common factors.
