Inverse Trigonometric Functions
They are defined as the inverse of the basic trigonometric functions which are sine, cosine, tangent, cotangent, secant, and cosecant.
The corresponding inverse functions are called arcsin, arccos, arctan, arccot, arcsec, arccsc.
These inverse functions in trigonometry are used to get the angle with any of the trigonometry ratios.
For example,
[tex]\displayystyle \sin 30^\circ=\frac{1}{2}[/tex]
Then:
[tex]\displaystyle arcsin \frac{1}{2}=30^\circ[/tex]
Since:
[tex]\tan 45^\circ=1[/tex]
Or, equivalently:
[tex]\displaystyle \tan \frac{\pi}{4}=1[/tex]
Then:
[tex]\displaystyle arctan(1)=45^\circ[/tex]
Or:
[tex]\displaystyle arctan(1)=\frac{\pi}{4}[/tex]
At the sewing store, Mariana bought a bag of mixed buttons. She got 80 buttons in all. 20 of the buttons were large. What percentage of the buttons were large?
Answer:
25%
Step-by-step explanation:
To find the percent of large buttons, divide the number of large buttons by the total, and divide that by 100:
(20/80) x 100
0.25 x 100
= 25
So, 25% of the buttons were large.
Answer:
25 percent of the buttons were large

Which translation takes y = | x + 2 | - 1 to y = | x | + 2 ?
Select one:
a. 2 units left, 3 units down
b. 2 units left, 3 units up
c. 2 units right, 3 units up
d. 2 units right, 3 units down
(Solve by graphing and determining the translation. Thanks in advance!)
Answer:
C
Step-by-step explanation:
y = | x + 2 | − 1 has a vertex at (-2, -1).
y = | x | + 2 has a vertex at (0, 2).
So the graph is translated 2 units right and 3 units up.

I need help with in the next 10 minutes I will give brainiest!!!!!
Answer:
x = 1 and y = 7
Step-by-step explanation:
First, you substitute the y into the first equation
-5x+2(7x)=9
-5x+14x=9
9x=9
x=1
Then put the x into the equation to find y
This is if you substitute using the second equation
y=7(1)
y=7
Write the equation of the line that has a slope of 5 and a y-intercept of 9.

An equilateral triangle with side lengths of 7 units is translated 3 units to the right. What is the length of one side of the triangle after the translation, in units? 3 units
Answer:
[tex]Sides= 7\ units[/tex]
Step-by-step explanation:
Given
[tex]Sides= 7\ units[/tex]
[tex]Translation = 3\ units[/tex] (to the right)
Required
Determine the length of one side after translation
It should be noted that when a shape, line, object is being translated by shifting its position, only the position of the shape, line or object changes not its length
This implies that, the length of the sides of the equilateral triangle remain unchanged.
Hence:
[tex]Sides= 7\ units[/tex]
Draw a model to help solve 5/6 + 1/4. write ur answer as a mixed number.
The required simplified solution of the given expression in the form of a mixed number is 1 1/12.
Given that,
To determine the solution of expression 5/6 + 1/4. in the form of a mixed number.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
here,
= 5 / 6 + 1 / 4
= [ 5×4 + 1×6 ] / [6×4]
= 26 / 24
= 13 / 12
= 1 + 1 /12 or 1 1/12
Thus, the required simplified solution of the given expression in the form of a mixed number is 1 1/12.

Which expression can be used to find the nth term of the sequence?
A) 6 + 10n
B)6 + 10(n - 1)
C)10 + 6(n - 1)
D)10 + 6n
Answer:
A.)
Step-by-step explanation:
I feel like it's A.) because the number sequence above continues to go on due to addition of 6 to each number. And now you are adding 6 to 10n because as stated before your supposed to add 6 to each number to get the answer in the sequence.

Find the measure of each numbered angle
The measure of each numbered angles are ∠1 = 56°, ∠2 = 56° and ∠3 = 74°.
What is Angle?An angle for any figure is formed by two rays which joins at a common point called vertex or node.
Usually angles are measured in degrees or radians.
Consider triangle PMQ
The sum of the interior angles of a triangle is 180°.
∠MPQ + ∠QMP + ∠PQM = 180°
58° + 66° + ∠1 = 180°
∠1 = 180° - (58° + 66°)
∠1 = 180° - 124°
∠1 = 56°
Now, ∠1 and ∠2 are vertically opposite angles. Hence they are equal.
∠2 = 56°.
Again, for triangle NQO
∠2 + ∠3 + 50° = 180°
56° + ∠3 + 50° = 180°
∠3 = 180° - (50° + 56°)
∠3 = 180° - 106°
∠3 = 74°
Hence ∠1, ∠2 and ∠3 are 56°, 56° and 74° respectively.

Can someone please how to do fractions in the lowest terms
Answer:
In order to out a fraction in lowest terms, you must divide by the Greatest Common Factor, or GCM, of the numerator and denominator in the fraction. Let's say we have the fraction 25/100. We know that the greastest common factor of 25 and 100 is 25, as 25 ÷ 25 = 1 and 100 ÷ 25 = 4 so 25/100 in lowest terms is 1/4:
25 25 1
___ ÷ ___ = ___
100 25 4
If the GCM of a fraction equals 1, the fraction is simplified. Because the only common factor of 1 and 4 is 1, we know this fraction is simplified.
1 1 1
__ ÷ ___ = ___
4 1 4

Consider the equation 5x^2-10x+c=0. What values of c result in the equation having a complex solutions? Represent your answer on the number line
Answer:
When we have a quadratic equation:
a*x^2 + b*x + c = 0
There is something called the determinant, and this is:
D = b^2 - 4*a*c
If D < 0, then the we will have complex solutions.
In our case, we have
5*x^2 - 10*x + c = 0
Then the determinant is:
D = (-10)^2 - 4*5*c = 100 - 4*5*c
And we want this to be smaller than zero, then let's find the value of c such that the determinant is exactly zero:
D = 0 = 100 - 4*5*c
4*5*c = 100
20*c = 100
c = 100/20 = 5
As c is multiplicating the negative term in the equation, if c increases, then we will have that D < 0.
This means that c must be larger than 5 if we want to have complex solutions,
c > 5.

The value of n for the given condition is 2(n - 2).
What is simplification?To simplify means to make anything easier. In mathematics, simplifying an equation, fraction, or problem means taking it and making it simpler. Calculations and problem-solving techniques simplify the issue. By eliminating all common factors from the numerator and denominator and putting the fraction in its simplest/lowest form, we can simplify fractions.
Given equation
(n + 8) + (n − 12) =
n + 8 + n - 12
solving constant separately and variables separately,
2n - 4
the common factor of 2 and 4 is 2
2(n - 2)
Hence the simplified form of an equation is 2(n - 2).
