Step-by-step explanation:

Total complex roots the function have is 4

To find the complex roots , we need the check the no.of alternative signs in f(x) and also in f(-x)

Given :

f(x) = x^8 + 2x^5 - 3x + 4

      The alternative signs in f(x) is  from 2nd term to 4th term

       i.e. ,  2nd term has '+' , 3rd term has '-' and again 4th term has '+'

       So, there are 2 alternative sign changing in f(x) ,

       that means it has two positive real roots.

f(-x) = (-x)^8 + 2(-x)^5 - 3(-x) + 4

       = x^8 -2x^5 + 3x + 4

       The alternative signs in f(-x) is from 1st term to 3rd term

        i.e. , 1st term has '+' , 2nd term has '-' and again 3rd term has '+'.

        So, there are 2 alternative sign changing in f(-x) ,

        that means it has two negative real roots.

The degree of f(x) is 8 , that means it has 8 roots

In that 8 roots , 2 are positive real roots and 2 are negative real roots. Thus remaining 4 roots are complex.

To solve for x, we just need to compute the inverse of A (if it exists) and multiply it by b. If A is invertible, then this method will give us the unique solution to the linear system Ax=b.

To solve a linear system of the form Ax=b using inverse matrices, we can first find the inverse of matrix A (if it exists) and then multiply both sides of the equation by \(A^-1\), giving us:

\(A^-1Ax = A^-1b\)

Since\(A^-1A\) is the identity matrix I, we can simplify the left-hand side to just x:

\(x = A^-1b\)

However, it's worth noting that computing the inverse of a matrix can be computationally expensive, particularly for large matrices.

So, while using inverse matrices can be a useful technique for solving small systems, it may not be the most efficient approach for larger systems. In those cases, other techniques such as Gaussian elimination or LU decomposition may be more appropriate.

The area under the curve for f(x) = 1/x(x-1) on [2,5] using R6 is 31/168

The area under the curve for f(x) = 1/x(x-1) on [2,5] can be determined using Riemann sum or R6.

We need to find the area under the curve of the function f(x) = 1/x(x-1) on the interval [2, 5].

The formula for the definite integral for the function f(x) from a to b is given by:

∫ab f(x) dx.

Using R6, the interval [2, 5] is divided into six sub-intervals of equal length

Δx = (5 - 2)/6 = 1/2.

The values of the function at the end-points of these intervals are:

f(2), f(2 + Δx), f(2 + 2Δx), f(2 + 3Δx), f(2 + 4Δx), f(5)

Substituting the values in the formula of R6 gives us:

R6 = [f(2) + f(2 + Δx) + f(2 + 2Δx) + f(2 + 3Δx) + f(2 + 4Δx) + f(5)] Δx

Note that f(x) is undefined for x = 0 and x = 1.

Therefore, we have to exclude the values of x that cause the denominator of f(x) to become zero,

i.e., 0 < x < 1 and x > 1.

R6 = [f(2) + f(2.5) + f(3) + f(3.5) + f(4) + f(5)] Δx= [1/2 - 1/3 + 1 - 4/7 + 1/3 + 1/12] (1/2)= [31/84] (1/2)

Thus, the area under the curve for f(x) = 1/x(x-1) on [2,5] using R6 is 31/168.

x = 22

Step-by-step explanation:

2x + 8 + 3x + 5 = 123    (external angle in a triangle = the two opposite angles)

5x = 123 - 13

5x = 110

x = 22

Answer: B

Step-by-step explanation:

By the Exterior Angle Theorem, we know that the exterior angle is equal to the sum of the two opposite interior angles.

(2x+8)+(3x+5)=123       [combine like terms]

5x+13=123                     [subtract both sides by 13]

5x=110                           [divide both sides by 5]

x=22

The solution for system of equation provided as per the given question will be x = -19 and y = 55 or (-19,55).

It is given that the equations are:

y = –3x – 2

y + 3x = -2 (equation 1)

5x + 2y = 15 (equation 2)

Multiplying y + 3x = -2 by 2 and subtracting from 5x + 2y = 15, we get:

2y - 2y + 5x -6x = 15 + 4

-x = 19

The Solution in inequality form is 7 ≤ x ≤ 10.

The Solution in interval notation: [7,10].

Given the data in the question;

-x - 8 ≤ -15 and -18 ≤ -x - 8

To solve, simplify the first part of the inequality by solving for x.

-x - 8 ≤ -15

Add 8 to both sides

-x - 8 + 8 ≤ -15 + 8

-x ≤ -7

Divide both sides by -1

Note that when dividing both sides of an inequality by a negative value, the inequality sign flips direction.

-x/-1 ≥ -7/-1

x ≥ 7

Next, simplify the second part of the inequality by solving for x

-18 ≤ -x - 8

Rewrite as

-x - 8 ≥ -18

Add 8 to both side

-x - 8 + 8 ≥ -18 + 8

-x ≥ -10

Divide both sides by -1

Note that when dividing both sides of an inequality by a negative value, the inequality sign flips direction.

-x/-1 ≤ -10/-1

x ≤ 10

Now, the intersection consist of the elements that are contained in both intervals.

Answer:

Answer:

Step-by-step explanation:

formula: divide the number you need to convert by 16

ex. 38 divided by 16 = 2.375

Step-by-step explanation:

I actually used p =2 and q=3

the It will be

2^3-1 + 3^2-1 = 1 (mod 2×3)

2^2 +3^1 = 1 (mod 6)

4+3= 1 (mod6)

7= 1 (mod6)

which is true.

therefore p^(q-1) + q^( p-1) = 1 ( mod pq) is true

To show that p^(q-1) + q^(p-1) = 1 (mod pq), we can use Fermat's Little Theorem, which states that if p is a prime number and a is an integer not divisible by p, then a^(p-1) = 1 (mod p). Using this theorem, we can first show that p^(q-1) = 1 (mod q), since q is a prime number and p is not divisible by q. Similarly, we can show that q^(p-1) = 1 (mod p), since p is a prime number and q is not divisible by p.

Therefore, we can write:

p^(q-1) + q^(p-1) = 1 (mod q)
p^(q-1) + q^(p-1) = 1 (mod p)

By the Chinese Remainder Theorem, we can combine these two equations to obtain:

p^(q-1) + q^(p-1) = 1 (mod pq)

Thus, we have shown that p^(q-1) + q^(p-1) = 1 (mod pq).
We'll use Fermat's Little Theorem to show that p^(q-1) + q^(p-1) = 1 (mod pq).

Fermat's Little Theorem states that if p is a prime number and a is an integer not divisible by p, then:
a^(p-1) ≡ 1 (mod p)

Step 1: Apply Fermat's Little Theorem for p and q:
Since p and q are prime numbers, we have:
p^(q-1) ≡ 1 (mod q) and q^(p-1) ≡ 1 (mod p)

Step 2: Add the two congruences:
p^(q-1) + q^(p-1) ≡ 1 + 1 (mod lcm(p, q))

Step 3: Simplify the congruence:
Since p and q are prime, lcm(p, q) = pq, so we get:
p^(q-1) + q^(p-1) ≡ 2 (mod pq)

In your question, you've mentioned that the result should be 1 (mod pq), but based on Fermat's Little Theorem, the correct result is actually:
p^(q-1) + q^(p-1) ≡ 2 (mod pq)

Step-by-step explanation:

After answering the presented question, we can conclude that The equation number of trials is predetermined: We're going to roll the dice 20 times.

An equation is a statement in mathematics that shows that two expressions are equal. It consists of two sides separated by an equal sign (=). For example, 2 + 3 = 5 is an equation because the expression on the left-hand side (2 + 3) is equal to the expression on the right-hand side (5).

Equations are used in many areas of mathematics, science, and engineering to describe relationships between quantities and to solve problems. For example, equations are used to model physical phenomena, such as the motion of objects, the behavior of fluids, and the propagation of waves. They are also used in finance, statistics, and many other fields to analyze data and make predictions.

In this case, the random variable X reflects the number of times a specific number appears after rolling a 20-sided die 20 times.

To see if this situation fits the binomial distribution model, we must look at the four conditions listed below:

The trials are impartial: Each throw of the dice is distinct from the others.

There are just two possibilities: Each roll can produce one of the 20 numbers or none at all.

The likelihood of success is constant: The probability of rolling a given number on a 20-sided dice is the same for each roll.

The number of trials is predetermined: We're going to roll the dice 20 times.

The correct statement is:

• If projw₁ is the orthogonal projection map onto W₁, then for all v in V, we have v - projw₁(v) ∈ W₂.

What is finite-dimensional inner product space?

In a finite-dimensional inner product space V, if V = W₁ ⊕ W₂ is the direct sum of two subspaces W₁ and W₂, the orthogonal projection map projw1 onto W₁ is a linear transformation that projects any vector v onto the subspace W₁. The projection of v onto W₁ is the closest vector in W₁ to v.

The statement v - projw₁(v) ∈ W₂ means that the difference between v and its projection onto W₁ lies in the subspace W₂. This is true because V is the direct sum of W₁ and W₂, which means any vector in V can be uniquely decomposed as the sum of a vector in W₁ and a vector in W₂. Therefore, the difference v - projw₁(v) will be in W₂.

This property holds for any vector v in V, so the statement is true.
