Question

ALGEBRA 2 WILL GIVE MEDAL

Answer 1

What are the amplitude, period, and midline of the function?

Amplitude: 4; period: 2π; midline: y = −1
Amplitude: 8; period: 2π; midline: y = 1
Amplitude: 8; period: π; midline: y = −1
Amplitude: 4; period: π; midline: y = 1

Answer 2

Use graph

Answer 3

Amplitude is half of the distance between the highest lowest points. The top and bottom points are 3 and -5, respectively. The distance between is 8, so the amplitude is half of 8, or 4.

Answer 4

so b?

Answer 5

First, we have to determine what the other 2 are. And second, B says that the amplitude is 8, so it can't be B.

Answer 6

Oh ok so

Answer 7

It will be A or D

Answer 8

D

Answer 9

Let's figure out what the period is. The period is the distance between the point on any wave and the same point on another wave. Kinda complicated way to say it, so a simpler way is just the distance between the tops of the waves. What is the horizontal difference between the top of two of the waves?

Answer 10

4

Answer 11

The distance of the red line in http://prntscr.com/7p9t23

Answer 12

3

Answer 13

Are you sure? Look at the number on the line.

Answer 14

Its 4

Answer 15

The amplitude is 4, but we're talking about the period here

Answer 16

Thats 3???

Answer 17

OH

Answer 18

Remember, it's horizontal distance, not vertical

Answer 19

2!

Answer 20

2 what? There's something after the 2.

Answer 21

Pi

Answer 22

Yeah, it's \(2\pi\) So it has amplitude of 4 and period of \(2\pi\). Which choice is that?

Answer 23

A

Answer 24

can u help me w a few more

Answer 25

Correct :)

Answer 26

Sure, I can help with a few more, just tag me in a separate question. :)
