B is correct. Explanation Below:
---
Line A never intersects Line B, as they are parallel lines-the slopes are the same-and parallel lines never intersect. 
Line A's Slope: (9-5)/(-1-1) = -2
Line B's Slope: (-6-2)/(4-0) = -2
---
Hope this helps!

If the graph of y=cos⁡θ has a change in amplitude and a vertical translation, the equation becomes y=acos⁡θ+d, where a,d∈N and 0
worty [1.4K]

Answer:

The amplitude is 3 and the downward vertical translation is 4 ⇒ 3rd answer

Step-by-step explanation:

* Lets revise some facts about the cosine function

- The Amplitude of cos(x) is the height from the center line to the

 peak (or to the trough). Or we can measure the height from

 highest to lowest points and divide that by 2.

- The Vertical Shift is how far the function is shifted vertically from

  the usual position.

* Now lets solve the question

∵ y = cos(Ф)

- There is a change in amplitude, it becomes a

- There is a vertical translation by b units

∴ y = a cos(Ф) + d

* Now lets look to the graph to find a and d

- From the graph:

∵ The highest value is -1

∵ The lowest value is -7

∴ The amplitude a = (-1 - -7)/2 = (-1 + 7)/2 = 6/2 = 3

∵ The highest value of y = cos(Ф) is 1

∵ The amplitude is 3

∴ The highest value of y = acos(Ф) = 3

∵ The highest value of y = acos(Ф) + d is -1

∴ d = 3 - (-1) = 4 ⇒ means downward vertical translation by 4

∴ y = 3 cos(Ф) - 4

* The amplitude is 3 and the downward vertical translation is 4

F(x)=2x+1 and g(x)=x2-7, find (f+g)(x)
SOVA2 [1]

Answer:

x^2 +2x -6

Step-by-step explanation:

f(x)=2x+1

g(x)=x^2-7,

(f+g)(x) = 2x+1 + x^2 -7

Combine like terms

           = x^2 +2x -6

And an 11 ounce bag of rice noodles makes 10 servings at that rate find how many ounces of noodles I needed for 19 servings to t
nikdorinn [45]

Answer:

20.9 ounces of rice noodles are required to make 19 servings.                    

Step-by-step explanation:

We are given the following in the question:

11 ounce bag = 10 servings

Ration of ounces of rice noodles to servings is:

\dfrac{\text{Weight of rice noodles}}{\text{Serivings}} = \dfrac{11}{10} = 1.1

We have to find ounces of noodles are needed for 19 servings.

Thus, we can write:

\dfrac{\text{Weight of rice noodles}}{19} = 1.1\\\\\Rightarrow \text{Weight of rice noodles} = 1.1\times 19\\\Rightarrow \text{Weight of rice noodles} =20.9\text{ ounces}

Thus, 20.9 ounces of rice noodles are required to make 19 servings.
