The equation for the horizontal asymptote will be y = -2.

Since the degree of the numerator and denominator of f(x) is the same both being 1, therefore horizontal asymptote exists and is given by:

y = Leading coefficient of numerator of f(x) / Leading coefficient of denominator of f(x)

=> y = -2/1

=> y = -2

The vertical asymptote will be f(x) = -2x / (x + 3). To find the vertical asymptote we will equate the denominator of f(x) = 0

=> x + 3 = 0

=> x = -3

The trigonometry ratios are tan(∅) = 2/3√10 and

csc(∅) = 7√10/20

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

csc²(∅) = 49/40

So, we have

csc(∅) = 7/(2√10)

Rationalize

csc(∅) = 7√10/20

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

1                1 - 3 = -2

Sum of the deviations = 0 - 1 + 1 + 2 - 2 = 0

percentage, a relative value indicating hundredth parts of any quantity.

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

x = $22,000

Hence, Deandre invested $22,000 in the 10% account and $30,000 - $22,000 = $8,000 in the 5% account.

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 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.

The sample mean of the number of movies watched by 25 students is 2.8 and the approximate sample standard deviation is 1.15.

(a) The sample mean X can be calculated by taking the average of the number of movies watched by all 25 students.

Step 1: Sum up the number of movies watched by all 25 students:

[tex]0 * 1 + 1 * 2 + 2 * 4 + 3 * 10 + 4 * 6 + 3 * 2 = 0 + 2 + 8 + 30 + 24 + 6 = 70[/tex]

Step 2: Divide the sum from Step 1 by the number of students (25):

70 / 25 = 2.8

So the sample mean X = 2.8

(b) The sample standard deviation s can be calculated using the formula:

[tex]s = \sqrt{\frac{ \sum(X - X_{mean})^2}{(n-1)} }[/tex]

Where [tex]X_{mean}[/tex] is the sample mean, n is the sample size, and Σ represents the sum of all values.

Step 1: Calculate [tex](X - X_{mean})^2[/tex]for each data point and sum up the values:

[tex](0 - 2.8)^2 * 1 + (1 - 2.8)^2 * 2 + (2 - 2.8)^2 * 4 + (3 - 2.8)^2 * 10 + (4 - 2.8)^2 * 6 + (3 - 2.8)^2 * 2\\ = 7.84 + 3.24 + 0.64 + 9.6 + 1.44 + 7.84\\ = 31.36[/tex]

Step 2: Divide the sum from Step 1 by (n - 1) = 24:

31.36 / 24 = 1.31

Step 3: Take the square root of the result from Step 2:

[tex]\sqrt{1.31} = 1.15[/tex]

So the approximate sample standard deviation s = 1.15 (rounded to two decimal places).

A dynamic array is an array with a big improvement: automatic resizing.

How does dynamic array works?

A random access, variable-size list data structure called a dynamic array, growable array, resizable array, dynamic table, or array list allows elements to be added or removed. It comes with standard libraries for many current, widely used programming languages.

A value of type array is stored in a static array variable. A pointer to an array value is stored in a dynamic array variable. The code you write to use either type of array differs very little because of automatic pointer dereferencing and automatic index padding.

Resizable dynamic arrays offer random access to its elements. They can have variable size initializations, and the software can change their size at a later time.

Given that:

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
