Find the equation of the graph given below. Notice that the sine function is used in the answer template, representing a sine function that is shifted and/or reflected.
Use the variable x in your equation rather than the multiplication × symbol.
y = __ sin (___) + (___)
Answers
Given:
The graph of a sine function.
To find:
The sine function.
Solution:
The general form of a sine function is
[tex]y=Asin(Bx+C)+D[/tex] ...(i)
Where, |A| is amplitude, [tex]\dfrac{2\pi}{B}[/tex] is period, [tex]-\dfrac{C}{B}[/tex] is phase shift and D is mid-line.
From the given graph it is clear that the minimum value of the function is -4 and the maximum value is 0.
[tex]|A|=\dfrac{Maximum-Minimum}{2}[/tex]
[tex]|A|=\dfrac{0-(-4)}{2}[/tex]
[tex]|A|=\dfrac{4}{2}[/tex]
[tex]|A|=2[/tex]
The graph is reflected across the mid-line, so A=-2.
And,
[tex]D=\dfrac{Maximum+Minimum}{2}[/tex]
[tex]D=\dfrac{0+(-4)}{2}[/tex]
[tex]D=\dfrac{-4}{2}[/tex]
[tex]D=-2[/tex]
Period of the function is 4π because it completer its one cycle in the interval of 4π.
[tex]4\pi=\dfrac{2\pi}{B}[/tex]
[tex]B=\dfrac{2\pi}{4\pi}[/tex]
[tex]B=\dfrac{1}{2}[/tex]
Phase shift is [tex]\dfrac{\pi}{4}[/tex].
[tex]-\dfrac{C}{B}=\dfrac{\pi}{4}[/tex]
[tex]-\dfrac{C}{\frac{1}{2}}=\dfrac{\pi}{4}[/tex]
[tex]C=-\dfrac{1}{2}\times \dfrac{\pi}{4}[/tex]
[tex]C=-\dfrac{\pi}{8}[/tex]
Putting [tex]A=-2,B=\dfrac{1}{2},C=-\dfrac{\pi}{8},D=-2[/tex] in (i), we get
[tex]y=-2\sin\left(\dfrac{1}{2}x-\dfrac{\pi}{8}\right)-2[/tex]
Therefore, the required equation is [tex]y=-2\sin\left(\dfrac{1}{2}x-\dfrac{\pi}{8}\right)-2[/tex].

X has a volume of 130 cm^3 and a surface area of 202^2 cm?.
The volume of Y is 638.69 cm^3.
What is the surface area of Y?
Answers
Answer:
992.43 cm²
Step-by-step explanation:
From the question given above, the following data were obtained:
Volume of shape X (Vₓ) = 130 cm³
Surface area of shape X (SAₓ) = 202 cm²
Volume of shape Y (Vᵧ) = 638.69 cm³
Surface area of shape Y (SAᵧ) =?
The surface area of shape Y can be obtained as follow:
Since the shape are similar, then:
Vₓ / Vᵧ = SAₓ / SAᵧ
130 / 638.69 = 202 / SAᵧ
Cross multiply
130 × SAᵧ = 638.69 × 202
130 × SAᵧ = 129015.38
Divide both side by 130
SAᵧ = 129015.38 / 130
SAᵧ = 992.43 cm²
Thus, surface area of shape Y is 992.43 cm²

In triangle RST, SQ=8 and QT=12. Find SW and UQ
Answers
Given:
In triangle RST, SQ=8 and QT=12.
To find:
The measure of sides SW and UQ.
Solution:
We know that centroid of a triangle is the intersection point of the medians and it divides each median in 2:1.
In the given figure SW and TU are medians and Q is the centroid. So,
[tex]\dfrac{SQ}{QW}=\dfrac{2}{1}[/tex]
[tex]\dfrac{8}{QW}=\dfrac{2}{1}[/tex]
[tex]\dfrac{8}{2}=QW[/tex]
[tex]4=QW[/tex]
Now,
[tex]SW=SQ+QW[/tex]
[tex]SW=8+4[/tex]
[tex]SW=12[/tex]
TU is a median. So,
[tex]\dfrac{QT}{UQ}=\dfrac{2}{1}[/tex]
[tex]\dfrac{12}{UQ}=\dfrac{2}{1}[/tex]
[tex]\dfrac{12}{2}=UQ[/tex]
[tex]6=UQ[/tex]
Therefore, the measure of SW is 12 units and the measure of UQ is 6 units.

Answers
Using the concept of critical point and the second derivative test, it is found that the correct option is:
D. f(x) has a relative maximum at x = 3 and a relative minimum at x = 5.
The critical points of a function [tex]f(x)[/tex] are the values of x for which [tex]f^{\prime}(x) = 0[/tex].Applying the second derivative test at the critical points, we have that:
If positive, that is, [tex]f^{\prime\prime}(x) > 0[/tex], it is a relative minimum.If negative, that is, [tex]f^{\prime\prime}(x) < 0[/tex], it is a relative maximum.If zero, that is, [tex]f^{\prime\prime}(x) = 0[/tex], we do not have sufficient information.In this problem:
[tex]f^{\prime}(3) = 0, f^{\prime\prime}(3) < 0[/tex], thus, there is a maximum at x = 3.[tex]f^{\prime}(5) = 0, f^{\prime\prime}(5) > 0[/tex], thus, there is a minimum at x = 5.The correct option is:
D. f(x) has a relative maximum at x = 3 and a relative minimum at x = 5.

To get this, you first add 7 to each side making the equation -4.818 = x/3.3
Then, you would need to multiply each side by 3.3 to get x by itself.
Your answer would be -15.8994.
Answer:
[tex]x=-15.8994[/tex]
Step-by-step explanation:
Skills needed: Solving one variable equations, Multiplication
1) We are given: [tex]-11.818=-7+\frac{x}{3.3}[/tex], and we need to solve for "[tex]x[/tex]"
2) In order to do this, you need to isolate the variable. In other words, you need to make sure the term involving "[tex]x[/tex]" is on one side of the equation, while everything else is on the other side.
In this case, the term involving "[tex]x[/tex]" is: [tex]\frac{x}{3.3}[/tex] In order to isolate [tex]\frac{x}{3.3}[/tex], you need to get rid of the "-7" on the right side. To get rid of it, we can add 7 to both sides.3) [tex]-11.818+7 = -7+\frac{x}{3.3} +7[/tex]
[tex]-11.818+7=-4.818[/tex]
-7 and 7 on the right side cancel out.
4) So you are left with: [tex]-4.818=\frac{x}{3.3}[/tex]
To get "[tex]x[/tex]", you need to multiply both sides by 3.3If you do this, the denominator will get cancelled out, leaving us with "[tex]x[/tex]" equaling a value.5) So then: [tex]-4.818 * 3.3 = x[/tex] (that star sign in between -4.818 and 3.3 is a multiplication sign)
[tex]-4.818*3.3 = -15.8994[/tex], so [tex]x = -15.8994[/tex]
