Answer:

91267

Step-by-step explanation:

The absolute value of the number in cubic equation is 6.

Let x1, x2, and x3 be the roots of the cubic equation x^3 - x - 1 = 0. By Vieta's formulas, we know that:

x1 + x2 + x3 = 0

x1x2 + x1x3 + x2x3 = -1

x1x2x3 = 1

We can use these properties to simplify the expression we are given:

x1\((x2 - x3)^2\)+ x2\((x3 - x1)^2\) + x3\((x1 - x2)^2\)

= x1(\(x2^2 - 2x2x3 + x3^2)\) + x2(\(x3^2 - 2x1x3 + x1^2\)) + x3(\(x1^2 - 2x1x2 + x2^2\))

= x1\(x2^2\)- 2x1x2x3 + x1\(x3^2\) + x2\(x3^2\) - 2x1x2x3 + \(x1^2\)x2 + x3\(x1^2\) - 2x1x2x3 + \(x2^2\)x3

= x1\(x2^2\)+ x1\(x3^2\) + x2\(x3^2\) + \(x1^2\)x2 + \(x1^2\)x3 + \(x2^2\)x3 - 6x1x2x3

= (\(x1^2 + x2^2 + x3^2\))(x1 + x2 + x3) - 3x1x2x3

= 3(\(x1^2 + x2^2 + x3^2\))

We can find \(x1^2 + x2^2 + x3^2\) by squaring the equation x1 + x2 + x3 = 0 and rearranging terms:

\((x1 + x2 + x3)^2\)= 0

\(x1^2 + x2^2 + x3^2\) + 2x1x2 + 2x1x3 + 2x2x3 = 0

\(x1^2 + x2^2 + x3^2\) = -2(x1x2 + x1x3 + x2x3)

Substituting the value of x1x2 + x1x3 + x2x3 = -1, we get:

\(x1^2 + x2^2 + x3^2\)= 2

Therefore, the expression we were given is equal to:

3(\(x1^2 + x2^2 + x3^2\)) = 3(2) = 6

Since 6 is a rational number, the absolute value of the number is simply 6.

In this problem, we are given a cubic equation and its three roots, and we are asked to find the value of a certain expression involving these roots. Our approach will involve manipulating the expression algebraically using the properties of the roots of the cubic equation, and then simplifying it to find its absolute value.

Conceptually, the arithmetic and geometric average returns are different measures used to describe the performance of an investment or an asset over a specific period.

The arithmetic average return, also known as the mean return, is calculated by adding up all the individual returns and dividing by the number of periods. It represents the average return for each period independently.

On the other hand, the geometric average return, also called the compound annual growth rate (CAGR), considers the compounding effect of returns over time. It is calculated by taking the nth root of the total cumulative return, where n is the number of periods.

When to use each measure depends on the context and purpose of the analysis:

1. Arithmetic Average Return: This measure is typically used when you want to evaluate the average return for each individual period in isolation. It is useful for analyzing short-term returns, such as monthly or quarterly returns. The arithmetic average return provides a simple and straightforward way to assess the periodic performance of an investment.

2. Geometric Average Return: This measure is more suitable when you want to understand the compounded growth of an investment over an extended period. It is commonly used for long-term investment horizons, such as annual returns over multiple years.

The geometric average return provides a more accurate representation of the overall growth rate, accounting for the compounding effect and reinvestment of returns.

In summary, the arithmetic average return is suitable for analyzing short-term performance, while the geometric average return is preferred  evaluating long-term growth and the compounding effect of returns.

Answer:B

count 2 and ~1/4 back and you get b

Answer:

64%

Step-by-step explanation:

If  9 out of 25 people are left-handed

That means 25-9 = 16 people are right handed

or 16/25 are right handed

Multiply the top and bottom by 4 to get it out of 100

64/100

Percent means out of 100

64% are right handed

The first 4 terms are 4 ,16,36 and 64 of the sequence (bn)n>=1 of partial sums of the sequence.

To find the first 4 terms of the sequence (bn)n≥1, we will calculate the partial sums as follows:

1. b1 = 4 (the first term)
2. b2 = b1 + 12 = 4 + 12 = 16 (sum of the first two terms)
3. b3 = b2 + 20 = 16 + 20 = 36 (sum of the first three terms)
4. b4 = b3 + 28 = 36 + 28 = 64 (sum of the first four terms)

So, the first 4 terms of the sequence (bn)n≥1 are 4, 16, 36, 64.

Now let's determine a recursive definition for bn. Notice that the difference between each term in the original sequence is 8 (12 - 4, 20 - 12, and 28 - 20). So, we can write the recursive definition as:

bn = bn-1 + 8n, for n > 1, and b1 = 4 (the first term).

This recursive definition can be used to find any term in the sequence (bn)n≥1 of partial sums.

If there exists a solution, then the vector (1, 6, 2) is a linear combination of the given vectors. We can solve this system of equations to determine the values of a, b, and c.

To determine whether the vector (1, 6, 2) is a linear combination of the vectors (1, 2, -1), (3, 1, 1), and (-4, 0, 6), we need to check if there exist scalars (constants) such that when we multiply each vector by its respective scalar and sum them up, we obtain the vector (1, 6, 2). Let's assume the scalars are a, b, and c for the three vectors respectively.

We can set up the following system of equations:

a(1, 2, -1) + b(3, 1, 1) + c(-4, 0, 6) = (1, 6, 2)

This can be written as:

(1a + 3b - 4c, 2a + b, -a + b + 6c) = (1, 6, 2)

56= 6.284r

divide both sides by 6.284

r= 56/6.284

r=8.9

approximately radius is 9in

therefore the area of the mirror that is largest would be

Area= 3.142*81

Area= 254.5 in^2

The largest area is 254.5 in^2

the maximum time that he can have in his last race is 23 seconds.

We know that the average can not be greater than 22.8 seconds, then if x represents the time of the last race, the maximum value that x can take is given by the equation:

(23.1 + 23.2 + 22.8 + 21.9 + x)/5 = 22.8

(That is the equation for the mean of the 5 times)

Solving that for x we will get:

(23.1 + 23.2 + 22.8 + 21.9 + x) = 5*22.8

Therefore, the SUBSET-SUM problem can be reduced to the PARTITION problem in polynomial time. Since SUBSET-SUM is NP-complete, it follows that PARTITION is also NP-complete.

a. Verifier for PARTITION problem:

Given an input (S, U, V) where S is a set of integers and U, V are partitions of S, we can verify in polynomial time whether the sum of elements in U is equal to the sum of elements in V. Therefore, PARTITION is in NP.

b. Reduction from SUBSET-SUM to PARTITION:

To show that PARTITION is NP-complete, we need to show that it is both in NP and NP-hard. We have already shown that it is in NP. Now we will reduce the SUBSET-SUM problem to PARTITION.

Given an instance of the SUBSET-SUM problem, which is a set of integers S = {a1, a2, ..., an} and a target integer T, we can construct an instance of the PARTITION problem as follows:

Let S' = S U {2T} and let U and V be two partitions of S' such that the sum of elements in U is equal to the sum of elements in V. We can easily verify that such partitions exist if and only if there exists a subset of S whose sum is equal to T.

If there exists a subset of S whose sum is equal to T, then we can add 2T to that subset and obtain two partitions of S' with equal sums. Conversely, if we have two partitions of S' with equal sums, then we can remove 2T from the partition that contains it to obtain a subset of S with sum T.

The coordinates after dilation are A (-0.5 , 1) , B(1,0.5) , C(0.5,-0.5) and D(0,0).

What is dilation?

Resizing an item uses a transition called dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. Yet, there is a variation in the shape's size.

Here , we need to find coordinates before using dilation. Then the coordinates are,

A=(-1,2) , B=(2,1) , C=(1,-1) and D=(0,0).

The scale factor = 0.5

For dilation coordinates we need to multiply coordinates by using scale factor. Then,

A = (-1,2) => (-1×0.5, 2×0.5) => (-0.5 , 1)

B = (2,1) => (2×0.5 , 1×0.5) => (1,0.5)

C = (1 , -1) => (1×0.5 , -1×0.5) => (0.5, -0.5)

D = (0 , 0) => (0×0.5 , 0×0.5) => (0,0)

Hence the coordinates after dilation are A (-0.5 , 1) , B(1,0.5) , C(0.5,-0.5) and D(0,0).
