Answer:

f(x) = 6 * sin(2x) - 10

Step-by-step explanation:

We can use the given information to write the general formula of a sinusoidal function as follows:

f(x) = A * sin(B(x - C)) + D

The amplitude of the function, A, is equal to the difference between the maximum and minimum values of the function, which in this case is -10 - (-4) = 6.

The period of the function, B, is equal to the distance between consecutive maximum or minimum points, which in this case is 2 - 0 = 2.

The phase shift of the function, C, is equal to the horizontal shift of the entire function, which in this case is 0 since the minimum point is at x = 0.

The vertical shift of the function, D, is equal to the y-coordinate of the minimum point, which in this case is -10.

Therefore, the formula of the given function is:

f(x) = 6 * sin(2(x - 0)) - 10

We can simplify this formula by removing the unnecessary parentheses and constants:

f(x) = 6 * sin(2x) - 10

This is the final formula for the given sinusoidal function, where x is entered in radians.

There is no input mapped into two or more outputs in the given relation:

(-3,4) (6,0),(-3,4),(-8,-2)

Thus, the relation is a function.

A relation maps elements of a set (inputs, usually defined by the variable x) into elements of another set (outputs, usually defined by the variable y).

So, for example, the coordinate pair (x, y) means that a relation is mapping the input x into the output y.

A relation is also a function if there is no input being mapped into two or more outputs.

For the case of the given relation:

(-3,4) (6,0),(-3,4),(-8,-2)

The mappings are:

-3  → 4   (this one appears twice)

6  → 0

-8  → -2

To express a mathematical operation symbolically, we employ a mathematical expression.

In mathematics, an expression is a sentence that has at least two terms and an operator in the middle. Expressions may be divided into two categories: numerical expressions, which include simply numbers, and algebraic expressions, which contain both numbers and variables. A mathematical expression consists of two parts: terms and operator, where terms refer to variables and integers. It is referred to as a constant term if an expression just contains numbers, and it is known as a coefficient if it also contains numbers and a variable.

We utilize expressions to symbolically represent any mathematical activity as well as mathematical models. The specifics of our computation, for instance, can be succinctly represented in terms of two or more mathematical terms. We can identify unknown numbers with the equal sign, allowing us to resolve difficult issues. In real life, we utilize expressions to figure out how much we make and spend, how quickly things change, how long it will take to go a certain distance, and other things. When calculating the rate of change, we use the differentiated term dy/dx. When calculating speed, time, and distance, as well as time and speed, we employ equations with variables.

to do this, find a value of x or y from one equation and plug it into the other. let's use x in this case

so we have 13x-6y=22 and x=y+6

for the x value of the first equation, plug in x=y+6 from the second equation to get:

13(y+6)-6y=22

then you solve for y,

13y+78-6y=22

7y=-56

y=-8

Therefore, the solution to this problem is  (x - 2)(x + 3) are the factors of p(x) (2x - 5).

An equation is a mathematical statement that is created by connecting two expressions using the equivalent sign. An example of an equation is 2x - 5 = 15. By resolving this equation, we may ascertain that the variable x has a value of 5.

Here,

Given, the polynomial in this case is 2x3 - 3x2 - 17x + 30.

It is necessary to factor the polynomial.

Let p(x) equal 2x3, 3x2, 17x, and 30.

P(xconstant )'s term is 30.

Factors of 30 are equal to 1, 2, 3, 5, 6, 10, 15, and 30.

Consider x = 2.

Replace x = 2 in p. (x),

2(2)³ - 3(2)² - 17(2) + 30 =p(2)

=> 2(8) - 34 - 3(4) + 30

= >16 - 16

= 0

So, x - 2 is a factor of 2x³ - 3x² - 17x + 30.

Now splitting the x² and x terms,

2x³ - 4x² + x² - 2x - 15x + 30= 2x³ - 3x² - 17x + 30

=> x(x - 2) - 15(x - 2) +  2x²(x - 2)

= > (x - 2)  *  (2x² + x - 15)

factoring  2[tex]x^{2}[/tex] + x - 15

= 2[tex]x^{2}[/tex] + 6x - 5x - 15

= - 5(x + 3)  +  2x(x + 3)

= (x + 3)(2x - 5)

Therefore, the solution to this problem is  (x - 2)(x + 3) are the factors of p(x) (2x - 5).

The value of a continuous function is that it produces a single output for any given input, no matter how small the change in the input. This makes it reliable and predictable, allowing for precise calculations and predictions.

Continuous functions are a type of mathematical function that produces a single output value for any given input. This means that no matter how small the change in the input is, the output value remains the same. This makes continuous functions reliable and predictable, allowing for precise calculations and predictions. As an example, a continuous function can be used to calculate how far an object will travel over a certain amount of time if provided with the initial velocity and acceleration. This is because the function will not change its output value when the input is altered, no matter how small the change is. Continuous functions are therefore an essential tool for many applications in mathematics and science.

The geometric sequence 2, −6, 18, −54, ... to represent the 9th term is

d. f(9)=f(8)+3(8)

A geometric sequence is a sequence of numbers in which each term after the first is found by multiplying the previous one by a fixed, non-zero number, called the common ratio. In the given sequence, the common ratio is -3, so the nth term of the sequence can be found by multiplying the previous term by -3.

Using the recursive formula for a geometric sequence, the nth term can be found by multiplying the first term, f(1), by the common ratio raised to the (n-1) power, or f(n) = f(1)•(-3)^(n-1). In the given sequence, f(1) is 2, so the 9th term can be found by multiplying 2 by -3 raised to the 8th power, or f(9)=f(1)•(-3)^8.

Alternatively, the nth term can also be found by multiplying the previous term, f(n-1), by the common ratio, or f(n) = f(n-1)•(-3). Since the 8th term in the given sequence is -54, the 9th term can be found by multiplying -54 by -3, or f(9)=f(8)•(-3).

Therefore, the 9th term in the given sequence is -486 and the correct answer is d. f(9)=f(8)+3(8).
