The trigonometric function gives the ratio of different sides of a right-angle triangle. The correct option is C.
What are Trigonometric functions?The trigonometric function gives the ratio of different sides of a right-angle triangle.
[tex]\rm Sin \theta=\dfrac{Perpendicular}{Hypotenuse}\\\\\\Cos \theta=\dfrac{Base}{Hypotenuse}\\\\\\Tan \theta=\dfrac{Perpendicular}{Base}\\\\\\Cosec \theta=\dfrac{Hypotenuse}{Perpendicular}\\\\\\Sec \theta=\dfrac{Hypotenuse}{Base}\\\\\\Cot \theta=\dfrac{Base}{Perpendicular}\\\\\\[/tex]
where perpendicular is the side of the triangle which is opposite to the angle, and the hypotenuse is the longest side of the triangle which is opposite to the 90° angle.
Let's solve the given statement as shown below.
A.)
sin C = tan A
sin C = 12/13
tan A = 5/12
Therefore, the given equation is not true.
B. sin C = cos B
sin C = 12/13
cos B = 5/13
Therefore, the given equation is not true.
C. sin C = cos A
sin C = 12/13

original price of CD: $13.00
Discount: 40%
Answer:
$7.80
Step-by-step explanation:
Multiply 0.4 (that is 40%) by 13
It would be 5.2
So subtract 5.2 from $13.00
7.8
So the CD price would be $7.80 with a 40% discount
Hope this helps you :)
Answer:
$5.20
Step-by-step explanation:
First you needed to multiply 0.40 and 13 so that would give you 5.2 so because you are dealing with money you need to add a two after the 2 in 5.2 to make it $5.20. I hope this helped!

Correct Question:
To find of :
∠QSR∠QExplanation:
∠QSR+∠QRT=180⁰
Reason:
linear pair
.°. ∠QSR+114⁰=180⁰
∠QSR=180⁰-114⁰
∠QSR=66⁰
Can also be done as follows:
To find value of ∠QSR first we have to find y
y⁰+(5y)⁰=114
Reason:
exterior opposite angle is equal to sum of interior angles
6y=114
y=114/6
y=19
y⁰+(5y)⁰+∠QSR=180⁰
Reason:
sum of angles of triangle =180⁰
6y+∠QSR=180⁰
6×19+∠QSR=180⁰
114+∠QSR=180⁰
∠QSR=180⁰-114⁰
∠QSR=66⁰
From second part we get the value of y

∠Q=95
Trevor is looking at purchasing a new cellular phone plan. Company A charges $35.25 a month, plus $.11/min for local calls. Company B charges $14.25 a month, plus $.32/min for local calls. Trevor stated that if he used x amount of minutes, the cost of the phone companies would be the same. For what amount of minutes, x, would Trevor's argument be true? Trevor is planning to use at least a 100 minutes for local a month. Which company would be cheaper for Trevor to use?
Answer: Trevor's argument will be true if he used 100 minutes.
Let x represent the amount of minutes that Trevor would use for the cost of the phone companies to be the same.
Company A charges $35.25 a month, plus $.11/min for local calls. This means that the total cost of making x minutes of call with Company A's plan is
32.25 + 0.11x
Company B charges $14.25 a month, plus $.32/min for local calls. This means that the total cost of making x minutes of call with Company B's plan is
14.25 + 0.32x
For both costs to be the same, the number of minutes would be
35.25 + 0.11x = 14.25 + 0.32x
0.32x - 0.11x = 35.25 - 14.25
0.21x = 21
x = 21/0.21 = 100

Mila reads at a rate of 3 paragraphs per minute.
After reading for 4 minutes, she had read a total of 12 paragraphs.
This situation can be represented with a linear equation written in point-slope form, where x represents the number of minutes and y represents the number of paragraphs.
Use this information to complete each statement about the linear equation.
Answer:
y= 3x
Step-by-step explanation:
This is honestly your basic times tables if we are being honest. We know that she read 3 paragraphs per minute. We also know that in 4 minutes, she read 12 paragraphs. 4 times 3 = 12. So the answer is y=3x.

Someone please help me i dont get how to do this?
Answer:
y= -3x-1
Step-by-step explanation:
hope this helps :)
Answer:
y = - 3x - 1
Step-by-step explanation:
The equation in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, - 4) and (x₂, y₂ ) = (2, - 7) ← 2 ordered pairs from the table
m = [tex]\frac{-7+4}{2-1}[/tex] = [tex]\frac{-3}{1}[/tex] = - 3 , thus
y = - 3x + c ← is the partial equation
To find c substitute any ordered pair into the partial equation
Using (1, - 4 ), then
- 4 = - 3 + c ⇒ c = - 4 + 3 = - 1
y = - 3x - 1 ← equation of linear function

graph the following function on the axes provided.
Answer:
Step-by-step explanation:
The graph of the piecewise function is attached below.
How to graph the following function on the axes provided?Function is a type of relation, or rule, that maps one input to specific single output.
The piecewise function is given as:
f(x) = - 6 for -6< x < 1
-2x + 5 for 1< x < 6
The above means that we plot the function on their interval or domain.
i.e. we plot f(x) = - 6 on the interval x < 0 and f(x) = -2x + 5 on the interval x < -6
Next, we plot the graph of the piecewise function.
Thus, The graph of the piecewise function is attached below.

Answer:
-n^3 – 5n + 4
Step-by-step explanation:
f(n) = -n^3 – 4

f(n)+ g(n) = (-n^3 – 4n)+(-n +4)
= (-n^3 – 4n -n +4)

A prime number is an integer greater than 1 with exactly two different positive factors, 1 and the number itself. There are three children in a family. Each of their ages is a prime number. The sum of their ages is 41 and at least two of the children have ages that differ by 16. Determine all possibilities for the ages of the children.
Answer:
Hence,
a=19,b=19,c=3
a=11,b=7,c=23
