Let's first review the Sin function before talking about Sin 0. Therefore Sin 0 value is 0.
The Sine, Cosine, and Tangent functions in trigonometry are used to determine the angles and length of a right-angled triangle, respectively.
The relationship between the angle, perpendicular side, and hypotenuse side is defined by the sine function.
Alternatively, you can use sin theta, which is equal to the right-angled triangle's perpendicular to hypotenuse ratio. Sin theta is the angle produced between the hypotenuse and adjacent side.
Definition Of Sin In Relation To Sin 0.
Sin 0 denotes that (x,y) is where the value of the x coordinate is 1, and the value of the y coordinate is 0. (1,0). In this case, the hypotenuse has a value of 1, and the opposing side or perpendicular has a value of 0.
As a result, if we set the numbers in the sin ratio for = 0, the perpendicular side to be 1, and the hypotenuse to be 0, we obtain,
Sin 0 = 0/1
Sin 0 = 0

Suppose that c and d vary inversely and that d=4/3 when c = 9. Write a function that models the inverse variation and find d when c = 3.
The equation for the inverse variation is:
d = 12/c
And evaluating that we can see that when c = 3, d = 4.
How to find the inverse variation equation?A genearl inverse variation equation can be written as:
y = k/x
Where k is a constant.
Here we know that there is an inverse variation between c and d, then we can write:
d = k/c
We know that d = 4/3 when c = 9, replacing that we will get:
4/3= k/9
9*(4/3) = k
12 = k
Then the equation is:
d = 12/c
Now we can evaluate this in c = 3 so we get:

What is the final step in solving the inequality 5 4x )< 6x 4?.
The inequality you provided is a linear inequality in one variable x. To find the solution to this inequality, we need to follow these steps:
First, we will simplify the inequality by combining like terms on the left side:
5 + 4x <= 6x + 4
4x <= x + 9
Next, we need to get x alone on one side of the inequality by subtracting x from both sides:
4x-x <= 9
3x <= 9
We will divide both sides of the inequality by 3:
x <= 3
The final step is to check our solution by plugging it back into the inequality and making sure that it satisfies the inequality: 5 + 4(3) <= 6(3) + 4
5 + 12 <= 18 + 4
17 <= 22 which is true
So the solution to the inequality 5 + 4x <= 6x + 4 is x <= 3. It's worth mentioning that this is the only solution that this inequality has since it's a linear inequality which has only one solution.

How do you decide whether to use substitution or elimination to solve a system?.
When deciding whether to use substitution or elimination to solve a system of linear equations, it is important to consider the size and complexity of the system.
Substitution is generally recommended for systems with two equations and two variables, as it can be a simpler and quicker approach. For larger systems with more equations and/or variables, elimination may be a better option as it can reduce the number of steps required to solve the system.
When using either method, it is important to keep track of all the steps you take and double check your work for accuracy. Additionally, both methods involve solving for one variable in terms of the others, so if you are dealing with an equation that already has only one unknown variable, then substitution could be the best approach. Ultimately, it is important to assess each situation individually and decide which method would be most effective.

What is the exponential function represented by the table below?
How do you know if a log function is increasing or decreasing?.
A logarithmic function is increasing when the base, b of the function is greater than one i.e., b>1 , and the function is decreasing when the base b lies in the interval (0,1).
Logarithmic functions are inverses of exponential functions, and any exponential function can be expressed in logarithmic form. The form of the equation is y = log₂x. This can be read as "y is equal to the logarithm of x, base 2" or "y is equal to the logarithm of base 2, x". In exponential function form, x = 2ʸ.
If the base of the logarithmic function is greater than 1, then the graph becomes increasing. A function whose value decreases to zero more slowly than any nonzero polynomial is called a logarithmically decreasing function.The graph of logarithmic functions always passes through a point i.e., (1,0).

What is standard error?The term "standard error" is used to refer to the standard deviation of various sample statistics, such as the mean or median. For example, the "standard error of the mean" refers to the standard deviation of the distribution of sample means taken from a population. The smaller the standard error, the more representative the sample will be of the overall population.
The relationship between the standard error and the standard deviation is such that, for a given sample size, the standard error equals the standard deviation divided by the square root of the sample size. The standard error is also inversely proportional to the sample size; the larger the sample size, the smaller the standard error because the statistic will approach the actual value.

Kaylee is going to a carnival that has games and rides. Each game costs $1.25 and each ride costs $2.50. Kaylee spent $12.50 altogether at the carnival and the number of rides she went on is twice the number of games she played. Graphically solve a system of equations in order to determine the number of games Kaylee played, x, and the number of rides Kaylee went on, y
To graphically solve a system of equations, we can plot the equations on a coordinate plane and find the point of intersection, which represents the solution to the system.
The first equation represents the total cost of the games, which is:
x(1.25) = 1.25x
The second equation represents the total cost of the rides, which is:
y(2.50) = 2.50y
The third equation represents the total cost of all games and rides, which is:
x(1.25) + y(2.50) = 12.50
We can also represent the fourth equation as the number of rides she went on is twice the number of games she played:
y = 2x
We can plot the first equation on the coordinate plane by treating x as the x-coordinate and 1.25x as the y-coordinate. We can plot the second equation in the same way, treating x as the x-coordinate and 2.5y as the y-coordinate.
We can plot the third equation as a line by treating x as the x-coordinate and 12.5-1.25x-2.5y as the y-coordinate.
Finally, we can plot the fourth equation as a line by treating x as the x-coordinate and 2x as the y-coordinate.
We can then find the point of intersection of the three lines, which represents the solution to the system of equations.
The point of intersection is the point (5,10) which means that Kaylee played 5 games and went on 10 rides.
