Answer:
- 60° (or - π/3) or 240° and 300°
Step-by-step explanation:
sin⁻¹ ((-√3) /2) : in third quadrant and 4th quadrant will produce negative sine value

In the equation 2
2 + 5 is the left side of the equation and 0 is the right side. In this equation only the left side contains the variable, y. In the equation 4 +5=-2x+10,theexpression
4 + 5 is the left side of the equation and - 2 + 10 is the right side. In this equation both sides have expressions that contain the variable, x.
1 Determine Whether a Number Is a Solution to an Equation
An equation in one variable is a statement made up of two expressions that are equal, and in the statement, at least one of the expressions contains the variable. The expres- sions are called the sides of the equation. Examples of equations in one variable are
2y + 5 = 0 4x + 5 = -2x + 10 3 = 9 z+2
In this section, we will concentrate on solving linear equations in one variable.

Find the amplitude and the period of the graphed function; please show work or steps.
Answers:
Amplitude = 2Period = 5pi/2===========================================
Explanation:
The lowest point occurs when y = -2. The highest point occurs when y = 2.
The vertical distance between the highs and lows is 4 units (since 2-(-2) = 2+2 = 4). This cuts in half to get 4/2 = 2.
The amplitude is 2. It measures the vertical distance from the midline to either the peaks or valleys.
-----------------------------
Note that this curve has two lowest points and one highest point shown. What we'll do is shift the graph over to the right so that each of those lowest points snap to a grid point. The lowest point on the left will move to where x = -pi, while the lowest point on the right snaps to x = 3pi/2. We'll keep each point at the same y coordinate.
The horizontal distance from x = -pi to x = 3pi/2 is
(3pi/2) - (-pi) = 3pi/2 + 2pi/2 = 5pi/2
This represents the horizontal distance from the left valley point to the right valley point. This is one full period of the curve. After we arrive at the right valley point, we repeat the process of going up and coming back down in this exact same fashion. The process is repeated forever to generate the cosine curve. The curve repeats itself every 5pi/2 units along the x axis.
Side note: any phase shift of a curve will have the same period as the original curve. This is why we're allowed to shift left or right to help find the period.

2^x-4x=0 find the value of x in the equation
9514 1404 393
Answer:
x ≈ 0.309906932381 or 4
Step-by-step explanation:
There are no algebraic methods of solving a mixed exponential and polynomial equation. The value of x can be found by guessing, or by other means such as trial and error or graphing.
Attached is a graph showing two solutions. x = 4 is the integer solution (2^4 = 4·4). The irrational solution is approximately x ≈ 0.309906932381. That precision is obtained by Newton's method iteration, easily done by a graphing calculator.

Evaluate b2−16a+5 when a=1/2 and b=7.
Answer:
11
Step-by-step explanation:
7x2=14
16x1/2=8
14-8=6
6+5=11
The evaluation of the given equation when the a is 0.5 and b = 7 so it should be considered as the 46.
Evaluation of the given equation;Since the equation is
[tex]b^2 - 16a + 5[/tex]
So,
[tex]= (7)^2 - 16(0.5) + 5[/tex]
= 49 - 8 + 5
= 46
Hence, The evaluation of the given equation when the a is 0.5 and b = 7 so it should be considered as the 46.

Answer:
Triangle a: 44.7°
Triangle b: 30.5°
Triangle c: 67.4°
Triangle d: 56.6°
Step-by-step explanation:
Recall: SOHCAHTOA
a. Reference angle = [tex] \theta [/tex]
Opposite = 19
Hypotenuse = 27
Apply SOH:
[tex] sin(\theta) = \frac{Opp}{Hyp} [/tex]
[tex] sin(\theta) = \frac{19}{27} [/tex]
[tex] \theta = sin^{-1}(\frac{19}{27}) [/tex]
[tex] \theta = 44.7 degrees [/tex] (nearest tenth)
b. Reference angle = [tex] \theta [/tex]
Opposite = 33
Adjacent = 56
Apply TOA:
[tex] tan(\theta) = \frac{Opp}{Adj} [/tex]
[tex] tan(\theta) = \frac{33}{56} [/tex]
[tex] \theta = tan^{-1}(\frac{33}{56}) [/tex]
[tex] \theta = 30.5 degrees [/tex] (nearest tenth)
c. Reference angle = [tex] \theta [/tex]
Opposite = 12
Adjacent = 5
Apply TOA:
[tex] tan(\theta) = \frac{Opp}{Adj} [/tex]
[tex] tan(\theta) = \frac{12}{5} [/tex]
[tex] \theta = tan^{-1}(\frac{12}{5}) [/tex]
[tex] \theta = 67.4 degrees [/tex] (nearest tenth)
d. Reference angle = [tex] \theta [/tex]
Hypotenuse = 20
Adjacent = 11
Apply CAH:
[tex] cos(\theta) = \frac{Adj}{Hyp} [/tex]
[tex] cos(\theta) = \frac{11}{20} [/tex]
[tex] \theta = cos^{-1}(\frac{11}{20}) [/tex]
[tex] \theta = 56.6 degrees [/tex] (nearest tenth)

Before she interviews participants, she must determine the number of possible routes participants can choose to use. Which expression represents the number of available options
a. 4!+3!
b. 4×3
c.4!×3!
d. 4!/3!
Answer:
Total possible routes participants can choose = 4×3 = 12 ways
The correct option is - b. 4×3
Step-by-step explanation:
Given - A behavioral economist studies transportation habits in an
urban center. She identifies 4 bus routes that connect to 3
different light rail routes available to participants in the study.
To find - Before she interviews participants, she must determine the
number of possible routes participants can choose to use.
Which expression represents the number of available options.
Proof -
Given that ,
Total bus routes = 4
So, number of possible ways she use the bus route = 4
Also,
The 4 bus route connects to 3 different light rail
So, possible ways that she use light rail = 3
∴ we get
Total possible routes participants can choose = 4×3 = 12 ways
The correct option is - b. 4×3

Constructed line PQ is the _______________ of line segment CD.
Answer:
Perpendicular bisector
Step-by-step explanation:
Construction done:
1). An arc is drawn from point O which intersects line 'l' at two points C and D.
2). From the points C and D two equal arcs on both the sides of the line 'l' have been drawn intersecting each other at points P and Q.
3). Points P and Q have been joined with the help of a straightedge.
Hence constructed line PQ is the PERPENDICULAR BISECTOR of the line segment CD.
