The value of k from the equation is k = 4

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

f ( x ) = ( 2 - k ) / ( 5x + k )   be equation ( 1 )

Now , the equation passes through the point P ( 3 , -2/19 )

On simplifying the equation , we get

Substituting the values of x and y in the equation , we get

y = ( 2 - k ) / ( 5 ( 3 ) + k ) )

-2/19 = ( 2 - k ) / ( 15 + k )

Multiply by ( 15 + k ) on both sides of the equation , we get

-2 ( 15 + k ) / 19 = 2 - k

Multiply by 19 on both sides of the equation , we get

-30 - 2k = 38 - 19k

Adding 2k on both sides of the equation , we get

38 - 17k = -30

Subtracting 38 on both sides of the equation , we get

17k = 68

Divide by 17 on both sides of the equation , we get

k = 4

Hence , the value of k = 4

The simplified form of (f o g)(x) = 8x²  + 8x + 4.

Differentiation is a process in calculus that is used to find the rate of change of a function at a specific point. It is the process of finding the derivative of a function.

To find (f o g)(x), we need to first find g(x) and then substitute that expression into f(x).

Given:

f(x) = 2x + 4

g(x) = 4x²  + 4x

So:

(f o g)(x) = f(g(x)) = f(4x²  + 4x) = 2(4x²  + 4x) + 4

Now we can substitute the expression for g(x) into f(x) and simplify:

= 2(4x²  + 4x) + 4 = 8x²  + 8x + 4

Hence, (f o g)(x) = 8x² + 8x + 4

The area of the mirror is 480 square inches

From the question, we have the following parameters that can be used in our computation:

A mirror that has the shape of a parallelogram (see attachment)

From the attachment, we have the following dimensions

Base length = 5 units

Height = 6 units

The area is the product of the dimensions

Since the side length of each square tile is 4 in, then we have

Area = 4 * 4 * 5 * 6

Answer:

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

given m = [tex]\frac{1}{3}[/tex] , then

y = [tex]\frac{1}{3}[/tex] x + c ← is the partial equation

to find c substitute (- 6, 5 ) into the partial equation

5 = [tex]\frac{1}{3}[/tex] (- 6) + c = - 2 + c ( add 2 to both sides )

7 = c

y = [tex]\frac{1}{3}[/tex] x + 7 ← equation of line

When the ellipse has co-vertices at (4,0) and foci at (0,+-4), the equation is y2/32+x2/16=1.

The algebraic equation y=mx+b is known as a linear equation. M serves as the y-intercept, and B serves as the slope. The previous clause has two variables, y and x, and is sometimes referred to as a "linear equation with two variables". Bivariate linear equations are those with two independent variables. The following are a few examples of linear equations: 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. When an equation takes the form y=mx+b, with m denoting the slope and b denoting the y-intercept, it is referred to as being linear.

The slope is (2/3 - 2/(3+h))/ h and as h is made closer and closer to 0, the slopes of the lines tend toward the derivative of the function f(x) at x = 3.

a) To find the slope of the line between the points (3, f(3)) and (3.1, f(3.1)), we use the formula m = (f(3.1) - f(3)) / (3.1 - 3) = (f(3.1) - f(3)) / 0.1

b) To find the slope of the line between the points (3, f(3)) and (3.01, f(3.01)), we use the formula m = (f(3.01) - f(3)) / (3.01 - 3) = (f(3.01) - f(3)) / 0.01

c) To find the slope of the line between the points (3, f(3)) and (3.001, f(3.001)), we use the formula m = (f(3.001) - f(3)) / (3.001 - 3) = (f(3.001) - f(3)) / 0.001

As h is made closer and closer to 0, the slopes of the lines tend toward the derivative of the function f(x) at x = 3.

Now to find a simplified rational expression for the slope of the line between (3, f(3)) and (3 + h, f(3 +h)), (h 0) :

The slope is equal to (f(3+h) - f(3)) / h

With f(x) = 2/x, we substitute it into the equation above and we get (2/(3+h) - 2/3) / h

The simplified rational expression for the slope is (2/3 - 2/(3+h))/ h

Answer:

To divide using long division, we first divide the leading term of the dividend (3r³) by the leading term of the divisor (r) to get the first term of the quotient (3r²). Then, we multiply the divisor (r + 4) by the quotient term (3r²) and subtract it from the dividend. We then bring down the next term of the dividend (11r²) and repeat the process. This will give us the quotient and the remainder.

The long division process is as follows:

(r + 4) | (3r³ +11r²-6r-18)

| 3r² (3r²)

|__

| -9r² +11r²-6r-18

|____

| -2r-18

|____

| +12r + 72

|____

| -36

|____

So the quotient is 3r² - 2r + 12 and the remainder is -36

And we can write the division as (3r³ +11r²-6r-18)÷(r + 4) = 3r² - 2r + 12 +(-36)/(r + 4)

x-(3x+8)=3(3x+8)-10

x-3x-8=9x+24-10

The statements which are always true in the triangle with interior angles, ∠2, ∠3, and m∠5, and exterior angles, ∠1, ∠4, and ∠5 are;

m∠5 + m∠6 = 180°

m∠2 + m∠3 = m∠6

m∠2 + m∠3 + m∠5 180°

An exterior angle is an angle that is formed by the extension of a side of the triangle and the side adjacent to the extended side.

The interior angles of the triangle are; angle ∠2, angle ∠3, and angle ∠5

The exterior angles at the interior angles of the triangle ∠2, ∠3, and ∠5 are angles  ∠1, angle ∠4, and angle ∠6 respectively.

Therefore, according to the exterior angle theorem, we get;

m∠1 = m∠3 + m∠5

m∠4 = m∠2 + m∠5

m∠6 = m∠2 + m∠3

The exterior angle and the adjacent internal angle are supplementary angles, therefore;

m∠2 + m∠1 = 180°

m∠3 + m∠4 = 180°

m∠5 + m∠6 = 180°

The angle sum property of a triangle indicates that the sum of the interior angles of a triangle is 180°, therefore;

m∠2 + m∠3 + m∠5 = 180°

Therefore, statement a is false because if 4 is a prime number, 6 is not a prime number.

For P(x, y) = (x, y)

Sine

sin θ = y / √(x² + y²)

Cosine

cos θ = x / √(x² + y²)

Tangent

tan θ = sin θ / cos θ

Cotangent

cot θ = 1 / tan θ

Secant

sec θ = 1 / cos θ

Cosecant

csc θ = 1 / sin θ

If we know that x = 2 and y = - 7, then exact values of trigonometric functions are, respectively:

Sine

sin θ = - 7 / √[2² + (- 7)²]

sin θ = - 7 / √53

sin θ = - 7√53 / 53

Cosine

cos θ = 2 / [2² + (- 7)²]

cos θ = 2 / √53

Tangent

tan θ = [- 7√53 / 53] / [2√53 / 53]

tan θ = - 7 / 2

Cotangent

cot θ = 1 / (- 7 / 2)

cot θ = - 2 / 7

Secant
