look for the highest degree of any term and you will end up multiplying

x^3( from first paranthesis)  *x( from second parenthesis) *x^3 ( from third paranthesis) so the highest degree will be x^ 3+1+3 = x^7

Step-by-step explanation:

ABCD reflects over \(X-\) axis.

Then translated to \((x+[6],y+[-1])\).

A single or multiple changes in a geometrical shape or figure is called Geometrical Transformation.

A geometrical transformation in which a geometrical figure changes his position to his mirror image about some point or line or axis is called Reflection.

We can see in the given figure that ABCD becomes EHGF after reflecting over \(X-\) axis.

So now A became the point E.

We can see in the figure that the coordinates of A were \((-5,2)\)

And now the coordinates of E are \((1,1)\)

So, \((-5+[6],2+[-1])=(1,1)\)

Hence the transformation is \((x+[6],y+[-1])\).

Answer:

x= -8y  / 5 +107

y = 535 - 5x / 8

Step-by-step explanation:

5x+8y=535

Subtract 8y from both sides.

5x=535−8y

Divide both sides by 5.

5x / 5 = 535 - 8y / 5

Dividing by 5 undoes the multiplication by 5.

x=  535−8y / 5

​ Divide 535−8y by 5.

x= -8y  / 5 +107

5x+8y=535

Subtract 5x from both sides.

8y=535−5x

Divide both sides by 8

8y / 8 = 535 - 5x / 8

Dividing by 8 undoes the multiplication by 8.

y = 535 - 5x / 8

Solutions of the given expressions are:

1: x² - 2x - 48 = 0 ⇒  x = 8 or -6

2: 6x² - 15 x = 0 ⇒  x = 0 or       x = 5/2

3: -x² + 8x = 7 ⇒   x = 7  or       x = 1

4:  x² + 4x + 17 = 8 - 2x ⇒ x = -3, -3

5:  4x² - 25 = 0 ⇒ x = 5/2 or x = -5/2

6:  6x² + 18x = x - 12 ⇒ x = -32 or x = -36

1. The given expression is,

x² - 2x - 48 = 0

Since we know that,

The quadrature formula for ax² + bx + c = 0 is

⇒ x = [-b±√(b²- 4ac)]/2a

Here,

a = 1

b = -2

c = -48

Now applying quadrature formula,

⇒ x = [2±√((-2)²+ 4x1x48)]/2x1

      = 8 or -6

Hence,

x = 8 or -6

2. The given expression is

   6x² - 15 x = 0

⇒ 3x(2x - 5) = 0

⇒ 3x = 0 or 2x-5 = 0

Hence,

⇒   x = 0 or       x = 5/2

3. The given expression is,

-x² + 8x = 7

We can write it,

⇒ x² - 8x + 7 = 0

Here,

a = 1

b = -8

c = 7

Applying quadrature formula we get

⇒ x = [8±√((-8)²+ 4x1x7)]/2x1

      = 7 or 1

Hence,

⇒   x = 7  or       x = 1

4.The given expression is,

x² + 4x + 17 = 8 - 2x

simplifying it we get,

⇒      x² + 6x + 9 = 0

⇒ x² + 2(3)x + 3² = 0

⇒               (x+3)² = 0

Hence,

x = -3, -3

5. The given expression is,

            4x² - 25 = 0

⇒         (2x)² - 5² = 0

⇒ (2x -5)(2x + 5) = 0

⇒ x = 5/2 or -5/2

Hence,

x = 5/2 or x = -5/2

6. The given expression is,

   6x² + 18x = x - 12

⇒ 6x² + 17x + 12 = 0

Here,

a = 6

b = 17

c = 2

Applying quadrature formula we get

⇒ x = [-17±√((17)²+ 4x6x12)]/2x6

      = -32 or -36

Hence,

x = -32 or x = -36

The number of 6-card hands  in which at least one card from each suit is equal to 8,184,220.

Total number of 6-card hands that can be formed from a deck of 60 cards is,

Using combination formula,

C(60, 6) = 50,063,860

Now, subtract the number of 6-card hands that do not contain at least one card from each suit.

There are 5 ways to choose the suit that will be missing from the hand.

Once this suit is chosen, there are 48 cards remaining in the other suits.

Choose 6 cards from this set, so the number of 6-card hands that do not contain any cards from the chosen suit is,

C(48, 6) = 12,271,512

Overcounted the number of hands that are missing more than one suit.

There are C(5, 2) ways to choose 2 suits that will be missing from the hand.

Once these suits are chosen, there are 36 cards remaining in the other 3 suits.

Choose 6 cards from this set, so the number of 6-card hands that do not contain any cards from the chosen suits is,

C(36, 6) = 1,947,792

We cannot have a 6-card hand that is missing more than 2 suits.

3 suits with no cards in the hand, which is not allowed.

Number of 6-card hands that have at least one card from each suit is,

C(60, 6) - 5×C(48, 6) + C(5, 2)×C(36, 6)

=50,063,860 - 5×  12,271,512 + 10 × 1,947,792

= 50,063,860 -61,357,560 + 19,477,920

= 8,184,220

Therefore, there are 8,184,220 of 6-card hands that have at least one card from each suit.

The area of the shelf is 12.5 square inches.

The coordinates of the vertices of the shelf are:

I(10, 15)
J(10, 10)
K(5, 10)

To find the area of the shelf, we can use the formula for the area of a triangle.

Since the shelf is in the shape of a right triangle, we can use the formula:

Area = (base × height) / 2

First, let's find the base and height of the triangle.

The base of the triangle is the horizontal distance between the points J and K.

To find this distance, we subtract the x-coordinates of J and K:

Base = Jx - Kx

Base = 10 - 5

Base = 5 inches

The height of the triangle is the vertical distance between the points J and I.

To find this distance, we subtract the y-coordinates of J and I:

Height = Iy - Jy

Height = 15 -10

Height = 5 inches

Now, we can substitute these values into the formula for the area:

Area = (base × height) / 2

= (5 × 5) / 2

= 25 / 2

= 12.5 square inches

Therefore, the area of the shelf is 12.5 square inches.

Answer:

hello your answer will be 9/2

The ARCH(q) model in (a) represents the conditional variance of the asset returns at time t as a function of past squared error terms. The GARCH(q,p) model in (b) extends the ARCH model by incorporating both past squared error terms and past conditional variances in the equation for the conditional variance. The unconditional variances of both models can be derived by taking the expectations of their respective conditional variance equations.

In the ARCH(q) model, the conditional variance \(\sigma^2t\) is given by \(\sigma^2t\) = \(\alpha 0 + \alpha 1 e t - 1^2 + \alpha 2 et-2^2 + \alpha 3et-3^2\), where et represents the standardized error term and \(\alpha 0, \alpha 1, \alpha 2, \alpha 3,\) are the model parameters.

In the GARCH(q,p) model, the conditional variance  \(\sigma^2t\) is given by   \(\sigma^2t\)  = \(\alpha 0 + \alpha1et-1^2 + \beta 1\sigma ^2t-1 + \beta 2\sigma^2t-2\), where et represents the standardized error term, \(\alpha 0, \alpha 1, \beta 1, \beta 2\) are the model parameters.

To derive the unconditional variances of the ARCH model in (a), we need to calculate the expectations of the squared error terms. Since \(et = zt\sigma t\)and zt ∼ N(0,1), we have \(E(et^2) = E((zt\sigma t)^2) = E(zt^2)\sigma t^2 = \sigma t^2\), where E(z\(t^2\)) is the expected value of the squared standard normal variable zt. Therefore, the unconditional variance of the ARCH model is \(\sigma ^2t = \alpha 0 + \alpha 1 \sigma t^2 + \alpha 2 \sigma t^2 +\alpha3 \sigma t^2 = (\alpha0 + \alpha1 + \alpha2 + \alpha3)\sigma t^2.\)

To derive the unconditional variances of the GARCH model in (b), we need to recursively substitute the conditional variance equation until it converges to a constant. This can be a complex process and involves solving equations iteratively.

In terms of comparison, the ARCH model in (a) only considers the squared error terms in the equation for the conditional variance, while the GARCH model in (b) incorporates both past squared error terms and past conditional variances. The GARCH model allows for more flexibility in capturing the persistence and volatility clustering of financial asset returns. However, estimating the GARCH model can be more computationally intensive due to the additional parameters. The choice between the two models depends on the specific characteristics of the financial data and the objectives of the analysis.

if f(x, y, z) = 4\(x\)\(y^{2}\)\(z^{3}\) arcsin (xz) , the value of fₓzᵧ is "24xyz²√(1-x²z²)".

To find fₓzᵧ, we differentiate f(x,y,z) partially with respect to x, then z, and finally y.

First, we take the partial derivative of f with respect to x:

fₓ = 4y²z³(arcsin(xz)) + 4xy²z³(1-x²z²)⁻ᵐ

where m = 1/2 * (1 - x²z²)⁻ⁿ, n = -1/2

Next, we take the partial derivative of fₓ with respect to z:

fₓz = 12xyz²(arcsin(xz)) + 4y²z²(1-x²z²)⁻ᵐ + 8xy²z²x(1-x²z²)⁻ⁿ

Finally, we take the partial derivative of fₓz with respect to y:

fₓzᵧ = 24xyz²√(1-x²z²)

Therefore, fₓzᵧ = 24xyz²√(1-x²z²) is the solution, where x, y, and z are the values of the given function f.
