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:

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:

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.

Answer:

There're too much possibilities of the answer.

Answer:

x=-10

Step-by-step explanation:

-3(x+7)=9

-3x-21=9

add 21 to both sides of equation

simplify divide both sides by like terms

simplify again and you have your answer

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:

30%

Step-by-step explanation:

28.60-22=6.60

6.60/22=0.3

Answer:

30% tip

Step-by-step explanation:

First, we need to find out how much money Brayden left for the tip. To find this, we'll subtract the initial bill from the remaining bill. It will look like this:

$28.60 - $22 = $6.60

We now know that Brayden left a tip of $6.60. Next, we need to set up a proportion to find out what percentage that is. For the first fraction, we need to plug in the tip and the initial bill. We'll use t to represent the tip, and w to represent the whole. It will look like this:

[tex]\frac{6.60t}{22w}[/tex]

Next, we need to set up the second fraction of the proportion. We know that every percent is out of 100, so we know that 100 will be our bottom number. We are solving for the percentage out of 100, so we will use x in its place. The final proportion will look like this:

[tex]\frac{6.60t}{22w} = \frac{x}{100w}[/tex]

Finally, we'll cross multiply and divide to get the final answer. First, multiply 6.60 by 100 to get 660. Finally, divide 660 by 22 to get a final answer of 30%. Brayden left a 30% tip on the bill. The final calculations are as follows:

6.60 X 100 = 660

660 / 22 = 30%

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:

Step-by-step explanation:

27/8 or 3 3/8 or 3.375

Answer:

27/8 or 3  3/8

Step-by-step explanation:

So you would convert both fractions into improper numbers.

So 2  1/4 would be 9/4

And 1  1/2 would be 3/2

Then you would multiply them both. Your answer would be 27/8

Answer:

y= -x-4

Step-by-step explanation:

x+y=-4

move the x to the other side

y= -x-4

Answer:

Step-by-step explanation:

When you distribute a positive sign to a parentheses, you essentially change nothing. So, you can drop all of the parentheses for this entire equation. Now combine like terms.

Answer:408=screen time

Step-by-step explanation:240+168 70%=168

make sure to like with the heart

Answer:

I believe 408 minutes a day

Step-by-step explanation:

So, I have my own method which is to divide the whole (in this case, 240) by 10 and multiply by whatever percent you have to multiply by and you add it to the whole.

ex.

240/10 = 24

24x7=168

240+168= 408

to do with 100s like 73% then divide the whole by 100 :)

Answer:

1. 65°

2. 115°

Step-by-step explanation:

1 is a linear pair

2 u just do 180 - 65 =___

that is ur answer

Answer:1. 65 2. 115

Step-by-step explanation:

the opposite side is 65 so is the one directly across it because it’s linear

A straight line is 180 so you subtract 65 from 180 to get 115
