Which is the correct label of the parallel lines?

Mathematics
1 answer:
liq [111]3 years ago
6 0

Answer:

a ∥ b

Step-by-step explanation:

The symbol "∥" means parallel lines.

Taking a look at the figure above, we have 2 parallel lines, labelled a and b.

A and B are two points on line "a", forming segment AB. However, segment AB is part of line "a".

Same applies to line "b", which has 2 points forming segment CD.

Therefore, the correct label if the parallel lines is a ∥ b

Help ASAP!!<br>Using the graphed function above, find the following
Alenkinab [10]

Answer:

Maximum: 1, Minimum: -3, Midline y = -1, Amplitude = 4, Period = \pi, Frequency \displaystyle =\frac{1}{\pi},  equation : f(x)=-4cos(2x)+1

Step-by-step explanation:

<u>Sinusoid Functions</u>

It refers to the oscillating functions like the sine or cosine which range from a minimum and maximum value periodically.

The graph shown can give us all the information we need to answer these questions:

Maximum: 1

Minimum: -3

The midline goes through the center value (mean) of the max and min values, i.e.

Equation of the midline:

\displaystyle y=\frac{1-3}{2}=-1

Amplitude is the difference between the maximum and minimum values

A=1-(-3)=4

The period is the time it takes to complete a cycle. We can see the minimum value is first reached at x=0 and next at x=\pi

Thus the period is

T=\pi

The frequency is the reciprocal of the period:

\displaystyle f=\frac{1}{T}=\frac{1}{\pi}

The angular frequency is

\displaystyle w=2\pi f=\frac{2\pi }{\pi}=2

The equation of the function is a negative cosine (since it starts at the minimum) or a shifted sine or cosine. We'll choose the negative cosine, knowing all the parameters:

f(x)=-4cos(2x)+1

I can't figure it out. <br>2x+2y=2<br>-4x+4y=12<br>​
koban [17]

Answer:

how to solve 2x+2y=2 , -4x+4y=12

this is  solving equations using substitution .... i have ALOT more but i juss dnt get this stuff

2x + 2y = 2      -4x + 4y = 12

x + y = 1

x = 1 - y

-4x + 4y = 12

-4(1 - y) + 4y = 12

(-4 + 4y) + 4y = 12

-4 + 8y = 12

8y = 16

y = 2

2x + 2y = 2

2x + 2(2) = 2

2x + 4 = 2

2x = -2

x = -1

Check.

-4x + 4y = 12

-4(-1) + 4(2) = 12

4 + 8 = 12

Answer: x = -1 and y = 2

Directions: Find the volume of each figure. Round to the nearest tenth if necessary.
balu736 [363]

Answer:

Step-by-step explanation:

square-based pyramid:

volume V = (⅓)b²h

    = (⅓)7²·16  

    ≅ 261.3 ft³

:::::

Can't help with question 3. I haven't learned triangle-based pyramids.

:::::

cone:

volume V = ⅓πr²h

              = ⅓π17²·20

              = 6052.8 yd³

:::::

can't help with question 7. Never did this kind of pyramid.
