The quadratic function's equation, when given the numbers in the table, can be found to be f(x) = x^2 - 5x + 6.

We are given a table of values and need to find the quadratic function in standard form: f(x) = ax^2 + bx + c. Let's use the points (-6, 72), (-4, 42), and (-3, 30).

For point (-6, 72):

72 = a(-6)^2 + b(-6) + c

For point (-4, 42):

42 = a(-4)^2 + b(-4) + c

For point (-3, 30):

30 = a(-3)^2 + b(-3) + c

Let's use the elimination method.

1 - 3) 42 = 27a - 3b

2 - 3) 12 = 7a - b

b = 7a - 12

Substitute this expression for b into the first equation:

42 = 27a - 3(7a - 12)

42 = 27a - 21a + 36

6 = 6a

a = 1

Now that we know a = 1, let's find b:

b = 7(1) - 12

b = -5

Finally, let's find c by substituting a and b into any of the original equations. We'll use the first one:

72 = 36(1) - 6(-5) + c

72 = 36 + 30 + c

6 = c

So, the quadratic function in standard form is:

f(x) = x^2 - 5x + 6

the area of the right-angled triangle with adjacent and opposite sides of 2 units is 2 square units.

what is right-angled triangle  ?

A right-angled triangle is a type of triangle that has one angle measuring exactly 90 degrees (a right angle). This angle is formed by the intersection of two sides of the triangle, which are called the legs or catheti, and it is opposite to the longest side of the triangle, which is called the hypotenuse. The hypotenuse is always opposite the right angle.

In the given question,

The area of a right-angled triangle is given by the formula:

Area = 1/2 x base x height

where the base and height are the two perpendicular sides of the triangle.

In this case, the adjacent side and opposite side of the right-angled triangle are both 2 units.

Let's call the hypotenuse of the triangle 'c'. Then, by the Pythagorean theorem, we have:

c² = 2² + 2²

c² = 8

c = √(8) = 2.8284 (rounded to 4 decimal places)

Now, we can use the trigonometric ratios to find the base and height of the triangle. In this case, we can use the tangent ratio:

tan(theta) = opposite/adjacent

tan(theta) = 2/2

tan(theta) = 1

theta = tan⁻¹(1) = 45 degrees

Therefore, the base and height of the triangle are:

base = adjacent x tan(theta) = 2 x tan(45) = 2 x 1 = 2

height = opposite x tan(theta) = 2 x tan(45) = 2 x 1 = 2

Now we can use the area formula to find the area of the triangle:

Area = 1/2 x base x height

Area = 1/2 x 2 x 2

Area = 2 square units

Therefore, the area of the right-angled triangle with adjacent and opposite sides of 2 units is 2 square units.

The solutions to the equation are x = a and x = a/2.

We can simplify the left-hand side of the equation using the common denominator of x^3:

(x-a)x/x^3 + (x-a)(-1)/(3a^2 x^3) + (x-a)(-2)/(3a x^3) + (x-a)(1)/(x^3)

= [(x-a)x^2 - (x-a)/(3a^2) - 2(x-a)/(3a) + (x-a)x]/x^3

= [(x^3 - a^3)/x^2 - (1/(3a^2))(x-a) - (2/(3a))(x-a)]/x

= [(x^2 + ax + a^2)(x-a)/(x^2 a^2) - (x-a)/(3a^2) - (2/3)(x-a)/a]/x

= (x^2 + ax + a^2)/(x^2 a^2) - 1/(3a^2) - 2/(3a)/x

= (3x^2 + 3ax + 3a^2 - x^2 a - ax^2 - a^3)/(3a^2 x^2)/x

= (2x^2 + 3ax + 3a^2 - ax^2 - a^3)/(3a^2 x^2)/x

= (x^2 + 3ax + 3a^2 - a^3)/(3a^2 x^2)/x

Now, we can see that the expression on the right-hand side is:

(x-a)/(x^3)

Multiplying both sides by x^3, we get:

(x-a)x = (x^2 + 3ax + 3a^2 - a^3)/3a^2

Multiplying both sides by 3a^2, we get:

(x-a)3a^2x = x^2 + 3ax + 3a^2 - a^3

Expanding (x-a)(3a^2)x, we get:

3a^2x^2 - 3a^3x = x^2 + 3ax + 3a^2 - a^3

Moving all terms to one side, we get:

2x^2 - 3ax + 2a^2 = 0

This is a quadratic equation, and we can solve for x using the quadratic formula:

x = [3a ± sqrt((9a^2 - 8a^2)/4)]/4

x = [3a ± a]/4

x = a or x = 2a/4 = a/2

Therefore, the solutions to the equation are x = a and x = a/2.

En resumen, al dividir Sea=4x⁵-x³+7 entre b(x)=2x⁵+x², obtenemos un cociente de 2x³-x² y un residuo de -2x²+7.

Para encontrar los cocientes y el residuo al dividir Sea=4x⁵-x³+7 entre b(x)=2x⁵+x², debemos realizar la división larga de polinomios. El procedimiento es similar a la división larga de números enteros:

        2x³    -x²    +0x   +0
   ---------------------------------
2x⁵ |  4x⁵   +0x⁴  -x³   +0x²  +0x  +7
        4x⁵   +0x⁴
       -------------
            0x⁴  -x³
            0x⁴  +0x³
           -------------
                   -x³   +0x²
                   -x³   +0x²
                   -------------
                            0x²  +0x

                                      --------
                                         -2x²  +7

Por lo tanto, el cociente de la división es 2x³-x², y el residuo es -2x²+7. Es importante notar que el grado del residuo (grado 2) es menor que el grado del divisor b(x) (grado 5), como se requiere en la definición de la división de polinomios.

Hope this helps!

Step-by-step explanation:

We have shown that P(F) is the direct sum of W1 and W2.

What is a polynomial?

a polynomial is an expression consisting of variables (also called indeterminates) and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables.

To prove that P(F) is the direct sum of W1 and W2, we need to show two things: first, that every polynomial in P(F) can be written as a sum of a polynomial in W1 and a polynomial in W2, and second, that this decomposition is unique.

Let's begin by showing that P(F) can be written as the direct sum of W1 and W2. Consider an arbitrary polynomial f(x) in P(F). We can write it as a sum of even and odd terms as follows:

f(x) = [f(x) + f(-x)]/2 + [f(x) - f(-x)]/2

The first term on the right-hand side is even, while the second term is odd. Let's define g(x) = [f(x) - f(-x)]/2 and h(x) = [f(x) + f(-x)]/2. Note that g(x) is odd and h(x) is even. Thus, we have expressed f(x) as a sum of an even polynomial h(x) and an odd polynomial g(x).

To show that this decomposition is unique, suppose that f(x) can be written in two ways as a sum of an even polynomial and an odd polynomial:

f(x) = h1(x) + g1(x) = h2(x) + g2(x)

where h1(x) and h2(x) are even polynomials, and g1(x) and g2(x) are odd polynomials. Then we have:

[h1(x) - h2(x)] = [g2(x) - g1(x)]

Since h1(x) - h2(x) is even, and g2(x) - g1(x) is odd, we have:

[h1(x) - h2(x)] = 0 and [g2(x) - g1(x)] = 0

This implies that h1(x) = h2(x) and g1(x) = g2(x), so the decomposition is unique.

Therefore, we have shown that P(F) is the direct sum of W1 and W2.

For example, if you want to find f(2), you would substitute x=2 into the equation:

f(x) = 6 + 3x

f(2) = 6 + 3(2)

f(2) = 6 + 6

f(2) = 12

Therefore, f(2) = 12.

Step-by-step explanation:

The value of f(x) is 18 given that the value of x is substituted as 4. The expression is usually solved with substitution method.

To find the value of f(x) for a given value of x, you need to substitute that value of x into the equation for f(x) and solve for f(x).

For example, if you want to find the value of f(x) when x = 4, you would substitute x = 4 into the equation for f(x) as follows:

f(4) = 6 + 3(4)

Answer:

To find the estimated standard error for the sample mean, we need to use the formula:

SE = s/√n

where s is the sample standard deviation and n is the sample size.

However, we are not given the sample standard deviation, but we are given the sum of squares (SS). We can use this to find the sample variance (s^2) and then take the square root to find the sample standard deviation.

For a sample size of n = 9, the degrees of freedom (df) are:

df = n - 1 = 9 - 1 = 8

Using the formula for the sample variance:

s^2 = SS/df = 1152/8 = 144

Taking the square root, we find the sample standard deviation:

s = √144 = 12

Now we can find the estimated standard error:

SE = s/√n = 12/√9 = 4

Therefore, the estimated standard error for the sample mean is 4.

Answer:

To find the estimated standard error for the sample mean, we need to divide the sample standard deviation by the square root of the sample size. However, we are given the sum of squares (SS), not the sample standard deviation, so we first need to calculate the sample variance. The formula for the sample variance is: s^2 = SS / (n - 1) where s^2 is the sample variance, SS is the sum of squares, and n is the sample size. Using the given values, we have: s^2 = 1152 / (9 - 1) = 144 Now we can find the estimated standard error: SE = s / sqrt(n) where SE is the estimated standard error, s is the sample standard deviation, and n is the sample size. Since s = sqrt(s^2), we have: SE = sqrt(s^2

The actual selling price of the camera after the 25% discount is $345.

The amount received by the buyer is the selling price of a product or service. Although the seller sets the price, a number of variables affect how the seller arrives at that particular figure. Depending on the seller's discretion, different customers may pay different prices for the same good or service.

If the normal price of the camera is $460, a 25% reduction in price would be:

25% of $460 = 0.25 x $460 = $115

This means the reduction in price when buying the camera duty-free is $115.

The highest and smallest values of a function, respectively, can either be found inside a specific range or distributed throughout the entire domain. They are also sometimes referred to collectively as the function's extrema. The plural forms of a function's maximum and minimum are called maxima and minima, accordingly.

Given data:

The overall revenue is thus:

y = (36 - 0.50x)(9600 + 160x)

Differentiate with respect to x.

y ' = (-0.50)(9600 + 160x) + 160(36 - 0.50x)

y' = -4800 - 80x + 5760 - 80x

y' = 960 - 160x

To find x, put y' = 0

960 - 160x = 0

x = 960/160 = 6 (critical point)

The assertion is accurate. This mean option that is selected should be true

The formula c = √(a 2 + b 2), where a and b are the lengths of the semi-major and semi-minor axes, respectively, yields the foci of a hyperbola.

. A hyperbola is a particular kind of conic section that resembles two slightly mirrored parabolic curves. It is described as the collection of all points in a plane where the difference between the locations of two fixed points (referred to as foci) is always constant.

Each of the two branches of a hyperbola resembles a parabola. In relation to the hyperbola's centre, the branches are symmetric. The semi-major axis is the distance between the centre and each vertex, whereas the semi-minor axis is the distance between the centre and each terminal of the transverse axis.

When a² = 25 and b² = 9,

the hyperbola (x-1)2/25 - (y+3)2/9=1 can be calculated.

In light of this, c = √(25 + 9) = √ (34).

2/5 = 12/30 3/6 = 15/30

Now, we can add the two fractions by simply adding their numerators (since they have the same denominator):

12/30 + 15/30 = 27/30

We can simplify the fraction by reducing it to the lowest terms. Both the numerator and denominator have 3 as a factor, so we can divide them both by 3:

27/30 = (3 x 9) / (3 x 10) = 9/10

Therefore, the sum 2/5 + 3/6 is equal to 9/10.

When we enter x = 3 into the first equation, we obtain: y = 2 log 3 y = 32     y = 9 .Hence, x=3 and y=9.

A log is a mathematical function used to calculate how many times the base, or initial value, must be increased by itself to produce the target value. In other terms, a logarithm is an exponent's negative action.

The base-10 logarithm is the most widely used type of logarithm, though there are other types as well. Some many mathematical and scientific tasks include the usage of logarithms, such as estimating the pH of a solution, gauging the volume of sound, and estimating population growth rates.

given

As we are aware that log x of y = 2, x2 = y.

We also understand that xy = 27.

When we change y in the second equation to x2, we obtain:

[tex]xx^{2} =7^{2} \\x^{3} = 27\\[/tex]

x = 3

When we enter x = 3 into the first equation, we obtain: y = 2 log 3 y = 32     y = 9 .Hence, x=3 and y=9.
