The format of the equation that shown below:

We know that the standard form of the parabola is y=ax²+bx+c. Thus, the vertex form of a parabola is y = a(x-h)² + k.

Given:

The General form of Vertex form is

y = a(x - h)² + k

where (h, k) are the vertex.

For Example, Pick a point on the graph other than the vertex.  Let's say you see the line pass through (1,5) and the vertex is at (3,4)

First the vertex gives

y = a (x - 3)² + 4

Put the values (1,5) into this equation.

5 = a (1 - 3)² + 4

Solve for a

5 = a x (-2)2 + 4

5 = 4a + 4

The improved high-speed mixer that allows bakers to produce cookies in less time will result in an increase in production, a decrease in cost, an increase in demand, and an increase in price of chocolate chip cookies.

Point A to Point B illustrates an increase in the production of chocolate chip cookies. This can be calculated using the formula: Change in Output = Output at Point B - Output at Point A. For example, if the output of chocolate chip cookies at Point A is 25 cookies per hour, and the output at Point B is 40 cookies per hour, then the change in output is 40-25=15 cookies per hour.

Point C to Point B illustrates a decrease in the cost of production of chocolate chip cookies. This can be calculated using the formula: Change in Cost = Cost at Point C - Cost at Point B. For example, if the cost of production at Point C is $2 per cookie, and the cost at Point B is $1 per cookie, then the change in cost is $2 - $1 = $1 per cookie.

Point C to Point D illustrates an increase in the demand for chocolate chip cookies. This can be calculated using the formula: Change in Demand = Demand at Point D - Demand at Point C. For example, if the demand for chocolate chip cookies at Point C is 100 cookies per hour, and the demand at Point D is 150 cookies per hour, then the change in demand is 150 - 100 = 50 cookies per hour.

Point A to Point D illustrates an increase in the price of chocolate chip cookies. This can be calculated using the formula: Change in Price = Price at Point D - Price at Point A. For example, if the price of chocolate chip cookies at Point A is $1 per cookie, and the price at Point D is $2 per cookie, then the change in price is $2 - $1 = $1 per cookie.

The actual distance between Spice Island and Kay Island is 85 miles.

Distance is a numerical measurement of how far apart two points or objects are. In mathematics, distance is often used in geometry to describe the length of a line segment connecting two points in a given space. It can also be used to describe the difference between two quantities or values. In physics, distance is a scalar quantity that measures the amount of space between two objects. It is often used to describe the separation between two points in a given direction.

There are various ways to calculate distance, depending on the type of space and the number of dimensions involved. In a one-dimensional space, such as a number line, distance can be calculated as the absolute value of the difference between two points. In a two-dimensional space, such as a plane, distance can be calculated using the Pythagorean theorem. In a three-dimensional space, such as our physical universe, distance can be calculated using the Euclidean distance formula.

Distance is an important concept in many fields, including mathematics, physics, engineering, computer science, and economics. In transportation and logistics, distance is used to determine the time and cost of moving goods and services from one location to another. In sports, distance is used to describe the length of a race or the distance traveled by a projectile.

If the scale on the map is 1 inch = 25 miles, this means that 1 inch on the map represents 25 miles in real life. To find the actual distance between the two islands, we need to multiply the distance on the map by the scale factor. So, the actual distance between the two islands is:

3.4 inches * 25 miles/inch = 85 miles

Let's call the amount Deandre invested in the 10% account x.

The amount he invested in the 5% account is $30,000 - x.

The interest he received from the 10% account is 0.10x and the interest he received from the 5% account is 0.05($30,000 - x).

The total interest received is $2600, so we can set up the equation:

0.10x + 0.05($30,000 - x) = $2600

0.10x + 0.05 * $30,000 - 0.05x = $2600

0.10x - 0.05x + 0.05 * $30,000 = $2600

0.05x = $2600 - 0.05 * $30,000

0.05x = $2600 - $1,500

0.05x = $1100

x = $1100 / 0.05

P(x) = 0.2·x³ + 0.5·x² + 0.4·x + 0.3

A polynomial consists of an expression that has two or more terms of (the same) variables with different powers or index.

The possible table in the question, obtained from a similar question on the internet is presented as follows;

Year;              [tex]{}[/tex]                1991     1993       1995        1997         1999

Cars Manufactured; [tex]{}[/tex]      1.4       11.4         39.8         96.2         190.2

(thousands)

The details in the table indicates that we get;

When x = 1991 - 1990 = 1, P(x) = 1.4

Which, based on the coefficients of x³, x², and x, corresponds with the first and the fourth polynomial.

p(x) = 0.5·x³ + 0.2·x² + 0.3·x + 0.4...(1)

p(1) = 0.5 × 1³ + 0.2 × 1² + 0.3 × 1 + 0.4 = 1.4

P(x) = 0.2·x³ + 0.5·x² + 0.4·x + 0.3...(4)

p(1) = 0.2 × 1³ + 0.5 × 1² + 0.4 × 1 + 0.3 = 1.4

When x = 1993 - 1990 = 3, we get in equation (1);

p(3) = 0.5 × 3³ + 0.2 × 3² + 0.3 × 3 + 0.4 = 16.6

The polynomial in equation (4) indicates that we get;

p(3) = 0.2 × 3³ + 0.5 × 3² + 0.4 × 3 + 0.3 = 11.4

Therefore, the polynomial in the fourth equation best represents the polynomial function for the cars manufactured in thousands where x represents the years since 1990

Verifying, we get;

When x = 5; p(5) = 0.2 × 5³ + 0.5 × 5² + 0.4 × 5 + 0.3 = 39.8

When x = 7; p(7) = 0.2 × 7³ + 0.5 × 7² + 0.4 × 7 + 0.3 = 96.2

When x = 9; p(9) = 0.2 × 9³ + 0.5 × 9² + 0.4 × 9 + 0.3 = 190.2

The square is shown in the complex plane, where each vertex can be represented as a complex number.

If we let the first vertex be 0, then the next vertex [tex]$a$[/tex] is at a distance of 1 unit along the real axis. The complex number representing [tex]$a$[/tex] is [tex]$1 + 0i$[/tex]. The vertex [tex]$b$[/tex] is at a distance of 1 unit along the imaginary axis, so its complex representation is [tex]$0 + 1i$[/tex]. Finally, the vertex [tex]$c$[/tex] is at a distance of 1 unit along the negative real axis, so its complex representation is [tex]$-1 + 0i$[/tex].

To find [tex]$b/a$[/tex], we divide the complex number representing [tex]$b$[/tex] by the complex number representing [tex]$a$[/tex]. We get [tex]$b/a = (0 + 1i) / (1 + 0i) = 0 + 1i$[/tex].

Similarly, to find [tex]$c/a$[/tex], we divide the complex number representing [tex]$c$[/tex] by the complex number representing [tex]$a$[/tex]. We get [tex]$c/a = (-1 + 0i) / (1 + 0i) = -1 + 0i$[/tex].

So, the values of [tex]$b/a$[/tex] and [tex]$c/a$[/tex] in rectangular form are [tex]0 + 1i[/tex] and [tex]-1 + 0i[/tex], respectively.

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

0°≤ ∅ ≤ 180°

Also, we have

cos(∅) = -3/7

The tangent is calculated as

tan(∅) = √[1/cos²(∅) - 1]

Substitute the known values in the above equation, so, we have the following representation

tan(∅) = √[1/(-3/7)² - 1]

So, we have

tan(∅) = √[49/9 - 1]

This gives

tan(∅) = √40/9

So, we have

tan(∅) = 2/3√10

Also, we have

cos²(∅) + sin²(∅) = 1

So, we have

(-3/7)² + sin²(∅) = 1

Evaluate

sin²(∅) = 1 - (-3/7)²

sin²(∅) = 1 - (9/49)

sin²(∅) = 40/49

Take the inverse of both sides

The claim of Carly is correct that the sum of the deviations for a data set will always be 0.

Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.

Sum of the deviations of a data set is always 0.

This is because that the sum of the positive deviations is equal to the sum of the negative deviations.

Let a data set be 3, 2, 4, 5, 1

Mean = (3 + 2 + 4 + 5 + 1) / 5 = 3

Values     Deviations

3               3 - 3 = 0

2               2 - 3 = -1

4               4 - 3 = 1

5               5 - 3 = 2
