1.02 quiz sinusoidal graphs
The characteristics of the sinusoidal function can be found from the given
graph of the function.
Correct Response;The minimum of the sinusoidal function is 1Method used to arrive at the above response;The sinusoidal function is the sine function that has the following general equation;
y = a·sin(b·(x - h)) + ka = The amplitude
b = Angular frequency
h = The horizontal shift
k = The vertical shift
Required:The minimum value of the sinusoidal function.
Solution;From the given graph, we have;
The amplitude, a = 2
The period, T = 10 = 2·π/b
b = π/5
The vertical shift, k = 3
The horizontal shift = 0
The minimum value of the function = k - a
Therefore;
The minimum value of the function is; 3 - 2 = 1Learn more about sinusoidal functions here:

You will need the above information to help you interpret the graph. First off, keep in mind that although this looks EXACTLY like the sine graph, if you plan on writing your equation as a function of cosine, then there WILL be a horisontal shift, meaning that a C-term will be involved. As you can see, the photograph on the right displays the trigonometric graph of [tex]\displaystyle y = 2cos\:\frac{\pi}{5}x + 3,[/tex] in which you need to replase "sine" with "cosine", then figure out the appropriate C-term that will make the graph horisontally shift and map onto the sine graph [photograph on the left], accourding to the horisontal shift formula above. Also keep in mind that the −C gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so you must be careful with your calculations. So, between the two photographs, we can tell that the cosine graph [photograph on the right] is shifted [tex]\displaystyle 2\frac{1}{2}\:units[/tex]to the left, which means that in order to match the sine graph [photograph on the left], we need to shift the graph FORWARD [tex]\displaystyle 2\frac{1}{2}\:units,[/tex]which means the C-term will be positive, and by perfourming your calculations, you will arrive at [tex]\displaystyle \boxed{2\frac{1}{2}} = \frac{\frac{\pi}{2}}{\frac{\pi}{5}}.[/tex]So, the cosine graph of the sine graph, accourding to the horisontal shift, is [tex]\displaystyle y = 2cos\:(\frac{\pi}{5}x - \frac{\pi}{2}) + 3.[/tex]Now, with all that being said, in this case, sinse you ONLY have a graph to wourk with, you MUST figure the period out by using wavelengths. So, looking at where the graph approximately hits [tex]\displaystyle [-10, 3],[/tex]from there to the y-intercept of [tex]\displaystyle [0, 3],[/tex]they are obviously approximately [tex]\displaystyle 10\:units[/tex]apart, telling you that the period of the graph is [tex]\displaystyle 10.[/tex]Now, the amplitude is obvious to figure out because it is the A-term, but of cource, if you want to be certain it is the amplitude, look at the graph to see how low and high each crest extends beyond the midline. The midline is the centre of your graph, also known as the vertical shift, which in this case the centre is at [tex]\displaystyle y = 3,[/tex]in which each crest is extended two units beyond the midline, hence, your amplitude. So, no matter how far the graph shifts vertically, the midline will ALWAYS follow.
**Now, the minimum value is the lowest possible value the graph touches, and in this case, the graph's lowest peaks cycle around [tex]\displaystyle y = 1,[/tex]therefore the minimum of his sinusoidal function is [tex]\displaystyle 1.[/tex]

Determine the volume of the entire Charter School.11 points
Answer: 512m³
Step-by-step explanation:
v = whl
The volume for left building:
v = w x h x l
v = 4 x 10 x 8
v = 320 m³
The volume for right and lower building:
v = w x h x l
v = 8 x 4 x 6
v = 192 m³
The total volume for the entire Charter School is: 320m³ + 192m³ = 512m³

A company produces fruity drinks that contain a percentage of real fruit juice. Drink
A contains 20% real fruit juice and Drink B contains 15% real fruit juice. The
company used 100.5 liters of real fruit juice to make 30 more liters of Drink A than
liters of Drink B. Write a system of equations that could be used to determine the
number of liters of Drink A made and the number of liters of Drink B made. Define
the variables that you use to write the system.
Answer:
x = amount of real fruit juice used to make Drink A
y = amount of real fruit juice used to make Drink B
Step-by-step explanation:
Let
x = amount of real fruit juice used to make Drink A
y = amount of real fruit juice used to make Drink B
1. The company used 100.5 liters of real fruit juice, then
2. Drink A:
x = amount of real fruit juice used
percentage of real fruit juice
Then
5x = amount of drink A produced
Drink B:
y = amount of real fruit juice used
percentage of real fruit juice
Then
amount of drink B produced
The company makes 30 more liters of Drink A than liters of Drink B, so
The system of two equations is
Is -6.743743… a rational or irrational number?
Your answer:
Rational because .743 repeats
Rational because the 6 is negative
Irrational because the number never ends
Irrational because the 6 is negative
It's rational because it contains a repeating digit pattern, 743 (first option).
In particular, if
x = -6.743743…,
then
1000x = -6,743.743743… .
Subtracting, we can eliminate the trailing end and solve for x exactly:
1000x - x = -6,743.743743… - (-6.743743…)
999x = -6,737
x = -6,737/999
Easy brainly!!! Please Help!!
Answer:
64
Step-by-step explanation:
Given :
h α 1 / sqrtk
h = k/sqrt(d)
Obtain the value of k, when. d = 4 and h = 20
20 = k / sqrt(4)
20 = k / 2
20 * 2 = k
k = 40
Therefore, the value of d when h = 5
h = k/sqrt(d)
5 = 40 / sqrt(d)
Square both sides
25 = 1600/d
25d = 1600
d = 1600 / 25
d = 64
d = 64

19+7 divided by 2 - 5 with brackets to equal 8?
Answer:
8
Step-by-step explanation:
Given that
19 + 7 divided by 2 - 5
So if we solve this we have to apply proper brackets
= (19 + 7) ÷ 2 - 5
= 26 ÷ 2 - 5
= 13 - 5
= 8
After solving this the answer is 8

Two Forest Ranger stations are located 9.8 miles apart. They both receive the same distress call. They determine that from Ranger Station 1 the distress call is at an angle of 46° and from Ranger Station 2 it is at angle of 52°. Which ranger station is closer to the distress call and by how much?
Answer:
Ranger station 2 is closer by 3.47 miles
Step-by-step explanation:
tan(46)=O/9.8
O (ranger station 2 to distress call)=10.15 miles
sin(46)=9.8/H
H (ranger station 1 to distress call)=13.62 miles
13.62-10.15=3.47 miles
So, ranger station 2 is closer by 3.47 miles
In circle O, chords AC and BD intersect at E. If MCD= 120 and MAB=100, what is BEC?
Answer:
D. 70°Step-by-step explanation:
∠BEC is supplementary with ∠BEA
Find the measure of ∠BEA
m∠BEA = 1/2(mCD + mAB)m∠BEA = 1/2(120° + 100°) = 110°Supplementary angles sum to 180°
m∠BEC + m∠BEA = 180°m∠BEC = 180° - 110° = 70°Correct choice is D
What is the measure for ECD
Answer:
118
Step-by-step explanation:
