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:

There're too much possibilities of the answer.

Answer:

22

Step-by-step explanation:

Missy has 156 cards in total. Since we know she has 4 times as many as them, we divide 156 by 4

156/4= 39

Ashe has 17 cards and we still don't know how many Caleb has. Since we know that they have 39 cards together, we need to subtract Ashe's cards to find how many Caleb has

39-17=22

Let's check our work

Caleb has 22 cards

Ashe has 17 cards

Together they have 39

Which is 4 times less than how many cards Missy has

Missy has 156 cards

We are correct!

Answer:

The value of angle 2 is 114 degrees

Step-by-step explanation:

We start with 180 degrees, since it is a Line.

To fine the other degree, subtract 66 from 180, which is 114

Angle 2 is 114 because of the theory of interior alternate angles are congruent. Angle 1 is 66 degrees because of the same reason.

Step-by-step explanation:

Put the x value in the equation to find your answer

Answer:

-16

-12

0

12

16

Step-by-step explanation:

y = 4(-4) = -16

y = 4(-3) = -12

y = 4(0) = 0

y = 4(3) = 12

y = 4(4) = 16

Answer: D. 20

Step-by-step explanation:

(4/5)(25/1)

= 100/5

=20

Answer:

12/20

Step-by-step explanation:

Cos is adjacent/hypotenuse. 12 is adjacent to angle C and 20 is the hypotenuse. 12/20 is the cosine of C.

Answer:

18$

Step-by-step explanation:

The answer is 18$ because you multiply 3.60$ by 5 lbs

Answer:

Option D

Step-by-step explanation:

We are given the two points of (5, 11) and (-5, -1).

Use the slope formula.

[tex]m=\frac{rise}{run}=\frac{-1-11}{-5-5} =\frac{-12}{-10} =\boxed{\frac{6}{5}}[/tex]

The correct option should be Option D.

Answer:

Step-by-step explanation:

Since this is a test/homework, I'll give you a hint.

For a linear graph, if you took a ruler, and traced the "dots", it should always be in a straight line.

Another way, is finding a pattern. I can't really explain this so much, since it's fairly basic. Just find two dots, and see if they are similar in any way. If they are, good job! Find another. If their isn't, maybe try searching for another.

The third way: You could use the equation mx+b=y, but this is just a bit ridiculous for this problem, since you could just eye it.

Hope this helps!
