Answer:

x = 10

Step-by-step explanation:

the angles shown are corresponding angles

corresponding angles are equal

12x - 4 = 10x + 16

subtract 10x from both sides

2x - 4 = 16

add 4 to both sides

2x = 20

divide both sides by 2

x = 10

Given that a parabola has

And that the standard form of a parabola can be expressed as

We are asked to find the value of p, h and k. This can be seen below.

Explanation

Recall, If a parabola has a horizontal axis, the standard form of the equation of the parabola is this

where p≠ 0. The vertex of this parabola is at (h, k). The focus is at (h + p, k). The directrix is the line x = h - p. The axis is the line y = k. If p > 0, the parabola opens to the right, and if p < 0, the parabola opens to the left.

Value of h and k

By comparison

Answer: h = 2 and k =2

Value of p

Also, by comparison

Answer : p =1.41

Writing the equation of the parabola in standard form

We can then use the given data to express the parabola in standard form as;

Based on the fact that 150g of syrup are needed when making 8 flapjacks, the quantity that is needed to make 16 flapjacks is 300 g.

The quantity of oats needed to make 8 flapjacks is 150 g.

Assuming direct proportion, the quantity of oats needed to make 16 flapjacks can be found by the formula:

= (Quantity of oats needed for 8 flapjacks x Number of flapjacks to be made) / Number of flapjacks made

Solving for the quantity of oats needed gives:
= (150 x 16) / 8

= 2,400 / 8

= 2,400 x 1/8

= 300 g

For the coordinates and their weights, the weight average is 5

The given parameters are:

Coordinate 3 has a weight of 1

Coordinate 6 has a weight of 2

The weight average is then calculated as:

Weight average = Sum of (Weight * Coordinate)/Sum of Weights

Substitute the known values in the above equation

So, we have the following equation

Weight average = (3 * 1 + 6 * 2)/(1 + 2)

Evaluate the product in the above equation

So, we have the following equation

Weight average = (3 + 12)/(1 + 2)

Evaluate the sum in the above equation

So, we have the following equation

Weight average = (15)/(3)

Evaluate the quotient in the above equation

So, we have the following equation

Weight average = 5

To write the height of Debbie as a fraction of the height of Leo in its simplest form is this: 17/18.

Writing one figure as a fraction of another can be done by representing the figures as numerators and denominators. In this case, what we will have is 85/90. That is the height of Debbie divided by the height of Leo.

To express this fraction in its simplest form will mean dividing the figures until they can no longer be divided. Using 5 as a common factor for dividing, we can conclude that the simplest form of the answer is 17/18.

The revenue is at a maximum after x = 9

The maximum is $ 261

9 hearing aids are produced and sold.

The revenue, R(x), of producing and selling 'x' Awesome Hearing Aids is modeled by the function,

R(x) = -3x² + 56x

We need to find the number of hearing aids produced and sold in order to maximize the revenue.

We use the differentiation method to find the maximum of the function R(x).

Differentiate R(x) with respect to x and equate it with 0,

R'(x) = -6x + 56

Then, -6x + 56 = 0

⇒ 6x = 56

⇒ x = 56/6 = 9.33 ≈ 9  [since x is the number of hearing aids]

Now we find the second derivative of R(x) at x = 9.

R''(x) = -6

⇒ R''(9) = -6 < 0

Since R''(9) < 0, the revenue R(x) is maximum at x = 9.

So the maximum revenue is obtained after x = 9.

Therefore maximum revenue = R(9) = -3 x 9²+56 x 9 = $ 261

Hearing aids produced and sold in order to maximize the revenue = 9

Hello there. To solve this question, we'll have to remember some properties about dividing polynomials.

Given the polynomials, we want to evaluate the division:

Rewriting it the way we perform long division:

We start with the higher degree terms, namely x^4 and x².

Dividing x^4 by x², we get x². Now we multiply every term from the division by this factor and subtract from the term being divided.

Now, we have a 2x³ as the higher degree term from the term being divided. Dividing it by x², we get 2x. Multiply each term of the divisor and subtract from it.

Finally, the highest degree term from the term being divided is x². Dividing it by x², we get 1. Multiply each term of the divisor and subtract it from the dividend.

Now, the highest degree term from the dividend is -x, when the highest degree term from the divisor is x². We cannot proceed with the long division anymore.

It means that we have a quotient:

And a remainder:

Notice if we rewrite it as:

We have the division P(x)/D(x) written in the form:

Where Q(x) and R(x) are the quotient and remainder polynomials.

The greatest common factor between the monomials can be determined as,

Thus, the above expression gives the required greatest common factor.

The most appropriate form of midpoint of line segment will be given by-

Coordinate of midpoint of AB =  ([tex]\frac{1}{2}, -\frac{5}{2}[/tex])

What is midpoint of a line segment?

At first, it is important to know about section formula. Let the coordinate of end point of a line segment is ([tex]x_1, y_1[/tex]) and ([tex]x_2, y_2[/tex]) respectively. Let another line intersects the line in the ratio m : n. Coordinate of point of intersection =[tex](\frac{mx_2 + nx_1}{m+n}, \frac{my_2 + ny_1}{m + n})[/tex].

If m = n =1, we get the coordinate of midpoint.

Coordinate of midpoint = [tex](\frac{x_1+y_1}{2}, \frac{x_2, y_2}{2})[/tex]

Midpoint of a line segment is that point which is equidistant from both the end points.

Here,

Coordinate of A = (-1, -9)

Coordinate of B = (2, 4)

Coordinate of midpoint of AB = ( [tex]\frac{-1 + 2}{2}, \frac{-9 + 4}{2}[/tex])

                                                 = ([tex]\frac{1}{2}, -\frac{5}{2}[/tex])

First, multiply all points by 2 (this is the first transformation)

A => A'(-4,-8)

B => B'(0,-2)

C => C'(4,-8)

Next, translate the previous points 6 units upward (which means add 6 units to each y-coordinate).

A' => X(-4,-2)

The equation of the line is given as y = -2x + 22. This means that when x  is equal to zero, y = 22. M also shows how steep the line is, being the gradient.

In order to arrive at a logical solution, we must assume the value of the slope as this is not given.

Assuming the slope of the line is -2, we thus can say:

The equation of a line that passes through a point (x₁,y₁) and a slope m is given by

(y - y1) = m (x - x1)

Recall that the slope, m = -2

While
Point (x1, y1) = (7, 8)

Hence, the equation of the line is:

y-8 = (-2) (x-7)

y-8 = -2x + 14

y = -2x+ 14 + 8

Hence,

y = -2x + 22

Thus, the equation of the line is:
