A dozen is equal to 12 so you have to do 12 x 9 = 108.

108 ÷ 4 = 27 so there was 27 rolls in each box.

Can you help please ASAP
V125BC [204]

Answer:

Step-by-step explanation:

External angle equals to the sum of opposite internal angles

z - 41° + z - 20° = z + 40°

2z - 61° = z + 40°

2z - z - 61° = 40°

z - 61° = 40

z = 40° + 61°

z = 101°

Plz help/ Trigonometric models and sine functions: plz show how you got and the GRAPH! Thx to anyone that can help
Shtirlitz [24]

Answer:

y=-2\sin(2x)-2 - The graph is attached below.

Step-by-step explanation:

Given : A sine function has the following key features:

Period = π , Amplitude = 2,  Midline: y = -2 , y-intercept: (0,-2)

The function is a reflection of its parent function over the x-axis.

To plot the graph :

Solution :

General form of sin function is y=A sin(Bx)+C

Where A is the amplitude

B=\frac{2\pi}{\text{Period}}

C is the midline    

Substitute the given key features  

A=2 , C=-2  

B=\frac{2\pi}{\pi}=2

The sin function is  y=2\sin(2x)-2

The function is a reflection of its parent function over the x-axis.

i.e, The coordinate became (x,y)→(x,-y)

The sin function is y=-2\sin(2x)-2

Now, We plot the graph of the sin function.

The graph is attached below.  

First point is midline i.e, (0,-2)

Minimum point is (\frac{\pi}{4},-4)

Please Help! The graph of y=f(x) is shown below. What are all of the real solutions of f(x)=0? (Picture of graph included)
qwelly [4]

Answer:

(7, 0), (-8, 0), (0, 0)

Step-by-step explanation:

y = f(x) = 0

the real solutions are the ones that cross the x-axis because when a point is on the x-axis, its y coordinate will be 0.

=> (7, 0), (-8, 0), (0, 0)
