A circle is shown. Angle Q R S is 84 degrees.
What is the measure of Arc Q S?
°
In the given diagram, the measure of arc QS is 168°
Calculating measure of an arcFrom the question, we are to determine the measure of arc QS
The measure of the arc is the angle subtended by the arc at the center of the circle.
From one of the circle theorems, we have that
The angle subtended by an arc of a circle at its center is twice the angle it subtends anywhere on the circle's circumference
In the given diagram,
The angle subtended by arc at the circumference of the circle = 84°
∴ The angle subtended by the arc QS at the center = 2 × 84°
The angle subtended by the arc QS at the center = 168°
Hence, in the given diagram, the measure of arc QS is 168°

Find sin(2x), cos(2x), and tan(2x) from the given information. sin(x) = 5 13 , x in quadrant i
The value of trigonometry terms sin(2x) is 120/169 and cos(2x) is 119/169 and tan(2x) is 120/119.
According to the statement
We have given that the sin(x) = 5/13 , x in quadrant iii
And we have to Find the value of cos x using the following:
So, For this purpose, we know that the trigonometry terms are:
sin2(x) + cos2(x) = 1;
or cos2(x) = 1-sin2(x)
And
cos2(x) = 1-(-5/13)2 =
cos2(x) = 144/169;
We know that the
In quadrant III both the sin and cos are negative so
cos(x) = -12/13 (after taking square roots).
And
Then tan(x) = sin(x)/cos(x) = (-5/13)/(-12/13) = 5/12.
Now you can use the angle addition formulas to find sin(2x), cos(2x), and tan(2x).
Now
sin(x + x) = sinx * cosx + cosx * sinx
= (-5/13)*(-12/13) + (-12/13)(-5/13) = 120/169
And
cos(x + x) = cosX * cos(x) - sinx*sinx
= (-12/13)(-12/13) - (-5/13)(-5/13)
= 119/169
So,
You could use the tan double angle formula, but it is easiest to use
tan(2x) = sin(2x)/cos(2x) = (120/169) / (119/169)
= 120/119.
So, The value of trigonometry terms sin(2x) is 120/169 and cos(2x) is 119/169 and tan(2x) is 120/119.

A hamster is 2 1/2 inches long a rabbit is 3 1/2 times as long as a hamster how long is the rabbit
A rectangle has dimension 23cm by 41cm and is made with a piece of wire How long will each length be for an equilateral triangle?
Each side of equilateral triangle will have the length equals to 42.7 cm.
Quadrilaterals
There are different types of quadrilaterals, for example, square, rectangle, rhombus, trapezoid, and parallelogram. Each type is defined accordingly to its length of sides and angles. For example, in a rectangle, the opposite sides are equal and parallel and their interior angles are equal to 90°.
The perimeter of a geometric figure is the sum of its sides. Thus, for a rectangle, the perimeter is 2L+2W.
You should find the perimeter of the rectangle.
2P=23+23+41+41= 128 cm
The equilateral triangle will have the same perimeter of the rectangle. An equilateral triangle presents the equal three sides, thus,

Which answer choice has the set of numbers ordered correctly from least to greatest
Its 1.71, 1 3/4, pie, 16/9
Answer: 1.71, 1 3/4, 16/9, pie
Step-by-step explanation: We convert all the numbers to improper fractions. 1.71 = 171/100. 1 3/4 = 175/100 because 3/4 is 0.75. pi is 3.14... which is larger than all of the other numbers. So, pi is the largest. For 16/9, we can just divide to find the solution. Once you divide, you will notice that the answer is 1.77777777... This means that it is larger than 1.71 and 1.75 so 16/9 is the second largest. 1.71 is smaller than 1.75 so the order is 1.71, 1 3/4, pie, 16/9

Answer:
(c) f(g(3)) > g(f(3))
Step-by-step explanation:
The relationship between the function values can be found by evaluating the functions.
f(g(3))The order of operations tells us we must first evaluate g(3).
g(x) = -3x +15
g(3) = -3(3) +15 = 6
Then we can evaluate f(x) for x=6:
f(x) = 7x
f(6) = 7(6) = 42
So, the composition is ...
f(g(3)) = 42
g(f(3))As above, we must first evaluate f(3):
f(3) = 7(3) = 21
Then we can evaluate g(x) for x=21:
g(21) = -3(21) +15 = -63 +15 = -48
That means the composition is ...
g(f(3)) = -48
ComparisonThe first is greater than the second.
42 > -48
f(g(3)) > g(f(3))

Answer:
s = -24
Step-by-step explanation:
This is a 2-step linear equation, so can be solved the way all 2-step equations are solved.
SolutionStep 1
Identify the constant term on the side of the equation with the variable term, and add its opposite to both sides.
[tex]7 = \dfrac{1}{6}s+11\qquad\text{given}\\\\7-11=\dfrac{1}{6}s+11-11\qquad\text{add $-11$ to both sides}\\\\-4=\dfrac{1}{6}s\qquad\text{simplify}[/tex]
Step 2
Multiply both sides by the inverse of the coefficient of the variable.
[tex](6)(-4)=(6)\left(\dfrac{1}{6}s\right)\qquad\text{multiply both sides by 6}\\\\\boxed{-24=s}\qquad\text{simplify}[/tex]
Alternate solutionOften, when equations contain fractions, you are advised to "eliminate fractions" as a first step. That generally means you multiply both sides of the equation by a suitable common denominator.
Here, the only denominator is 6, so the fraction can be eliminated by multiplying both sides of the equation by 6.
[tex]7=\dfrac{1}{6}s+11\qquad\text{given}\\\\6(7)=6\left(\dfrac{1}{6}s+11\right)\qquad\text{multiply both sides by 6}\\\\42=s+66\qquad\text{simplify}\\\\42-66=s+66-66\qquad\text{add the opposite of 66 to both sides}\\\\\boxed{-24=s}\qquad\text{simplify}[/tex]
You will note this requires the same number of steps, but you don't have to mess with fractions after the first step.
CheckThe value we found for the variable can be checked in the original equation.

We know that there are 109 students in the fourth grade, who each have x cupcakes. In order to find the total amount of cupcakes, we could add all of the cupcakes together to get:
x + x + x + x + .... x
109 times because there are 109 students.
This can be simplified to become 109x.
