Answer:
Therefore,
The value of arcsin(0) is 0° or 180° or 360° or 540° or n×180° so on.
Step-by-step explanation:
To Find:
arcsin(0) in degrees =?
Solution:
' arcsin ' a mathematical function that is the inverse of the sine function.
Therefore, arcsin (x) is called the inverse sine function.
It is the angle whose sine is the number x.
So here we require angle in degree for which the Sine is '0'.
It is also written as
We Know that
Therefore,
Also integer multiples of 180° will have
Where n = integer
Therefore for '0' we can have 2×180° , 3×180° , 4×180°....and so on i.e 360° , 540° and so on
Therefore,
The value of arcsin(0) is 0° or 180° or 360° or 540° or n×180° so on.
The relation that is a function is:
b. y = 2x² - 3x + 7
<h3>When a relation is a function?</h3>A relation is a function if each value of the input is mapped to only one value of the output.
Hence, when both x and y are squared, we have that , hence it is not a function. This is the case for items a and c.
For item d, we have that the relation can be simplified as follows:
x = -y² + 3y
x = y(-y + 3)
The solution above, is associated to two values of y, hence it is also not a function. Then the function is given by:
b. y = 2x² - 3x + 7
In the solution, it can be seen that for each input x, only one value of y can be generated.

Answer:182 ways
Step-by-step explanation:
Given
there are total of 10 workers in office
No of ways to select 4 workers out of 10 workers
(b)If hugo and Viviana refuse to work together then
then no of ways in which hugo anf Viviana work together
Therefore total no of ways in which Hugo and Viviana do not work together is
