Answer:
The function that could be the function described is;
[tex]f(x) = -10 \cdot cos \left (\dfrac{2 \cdot \pi }{3} \cdot x \right ) + 10[/tex]
Step-by-step explanation:
The given parameters of the cosine function are;
The period of the cosine function = 3
The maximum value of the cosine function = 20
The minimum value of the cosine function = 0
The general form of the cosine function is presented as follows;
y = A·cos(ω·x - ∅) + k
Where;
[tex]\left | A \right |[/tex] = The amplitude = Constant
The period, T = 2·π/ω
The phase shift, = ∅/ω
k = The vertical translation = Constant
Therefore, by comparison, we have;
T = 3 = 2·π/ω
∴ ω = 2·π/3
The range of value of the cosine of an angle are;
-1 ≤ cos(θ) ≤ 1
Therefore, when A = 10, cos(ω·x - ∅) = 1 (maximum value of cos(θ)) and k = 10, we have;
y = A × cos(ω·x - ∅) + k
y = 10 × 1 + 10 = 20 = The maximum value of the function
Similarly, when A = 10, cos(ω·x - ∅) = -1 (minimum value of cos(θ)) and k = 10, we get;
y = 10 × -1 + 10 = 0 = The minimum value of the function
Given that the function is a reflection of the parent function, we can have;
A = -10, cos(ω·x - ∅) = -1 (minimum value of cos(θ)) and k = 10, to get;
y = -10 × -1 + 10 = 20 = The maximum value of the function
Similarly, for cos(ω·x - ∅) = 1 we get;
y = -10 × 1 + 10 = 0 = The minimum value of the function
Therefore, the likely values of the function are therefore;
A = -10, k = 10
The function is therefore presented as follows;
y = -10 × cos(2·π/3·x) + 10

Answer:
UT = 8
Step-by-step explanation:
From the picture, we can make the following equation...
5 + 2x - 6 = x + 6
By solving it we get
5 + 2x - 6 = x + 6
2x - 1 = x + 6
2x = x + 7
x = 7
Therefor if UT = 2x - 6, then UT is equal to...
2x - 6 = UT
2(7) - 6 = UT
14 - 6 = UT
8 = UT

25 points What is the equation for the line in slope-intercept form
Answers
Answer:
y=8x
Step-by-step explanation:
x=1 y= 8
x=2 y=16
8=m+b
16=2m+b
m=8
y=8x
The equation of a line is on the form y = mx + b where m is the slope and b is the y-intercept.
First let’s find the slope:
m = (y2-y1)/(x2-x1) = (16-0)/(2-0) = 16/2= 8
So we have y = 8x + b
We substitue one of the coordinates to find b. Let’s substitute (0,0)
We get 0 = 0 + b. So b = 0
The equation of the line is y = 8x

Which one doesn't belong? Explain your reasoning
Answers
Answer:
A does not belong
Step-by-step explanation:
A does not belong because it is the only option with parallel lines. All other answer options have lines that intersect with eachother.
Answer:
The answer that they're looking for is A. The first set doesn't belong because it's the only one in which the lines are parallel.
However, one could argue that none of the others belong;
B is the only one with two lines instead of 3
C is the only one with three lines converging at the same point.
D is the only one with more than one point of intersection
But it is pretty clear that the answer sought is A. It's the only one with parallel lines.

Step-by-step explanation:
If she needs 1/4 cup of powdered milk for one batch, then we multiply 1/4 by 4 to see how much she needs for 4 batches, which is 4/4, or one whole.
If she needs 3/2 cups of whole wheat for one batch, then we multiply 3/2 by 4 to see how much she needs for 4 batches, which is 12/2, or 6.
Then we combine 6 and 1, which is 7.

Step-by-step explanation:
This was a lucky guess for me on my homework and it was correct sooooo.... I don't really have an explanation...
Definition: For vector [tex]v=<a,b>[/tex], the magnitude is defined as [tex]|v|=\sqrt{a^{2} +b^{2} }[/tex], and the direction of the vector is defined as [tex]tan^{-1}(\frac{b}{a} )[/tex].
Here, [tex]v=<2,7>[/tex].
Then, magnitude is:
[tex]|v|=\sqrt{2^{2}+7^{2} } \\|v|=\sqrt{4+49 } \\|v|=\sqrt{53} \\|v|=7.3[/tex]
The direction is:
[tex]tan^{-1}(\frac{7}{2} )=74^{o}[/tex].
So, the correct option is 7.3,74°.
