Question

Algebra help!!!

Answer 1

To find the period, you should determine after how much time, a particular point repeats itself.
For first graph, lets pick a peak point at say x--5
when does that peak repeat ? (at what value of x ?)

Answer 2

Is that for the first question or for the second?

Answer 3

First.

Answer 4

Ok.

Answer 5

infact 'To find the period, you should determine after how much time, a particular point repeats itself.'
is valid for both

Answer 6

4 seconds

Answer 7

the second question is about 12

Answer 8

$ is correct :)

Answer 9

**4

Answer 10

in 1) the peak repeats at x=1 again, right ?
so, from -5 to 1 is.... ?

Answer 11

6

Answer 12

yes :)

Answer 13

oh, yes...i saw numbers now..
for 2. its 6
fo other its 4

Answer 14

OK!! Thanks!

Answer 15

welcome ^_^

Answer 16

I have another one Can you help??

Answer 17

does any point on that graph repeats itself ?

Answer 18

I don't think so.

Answer 19

But I was wondering if there's just another way to do it. :)

Answer 20

so for that it was non-periodic

Answer 21

Yup!

Answer 22

I posted question 4. :)

Answer 23

an u tell irs period ?

Answer 24

What?

Answer 25

The period is 1.

Answer 26

But I don't know how to get amplitude.

Answer 27

the peak point which is at 2, when does it repeat ?
period is not 1

Answer 28

oh I see 2

Answer 29

yes :)

Answer 30

Ampitude = |Highest point -lowest point| /2

Answer 31

and the amplitude is 0.5

Answer 32

yes,
A = |0-1|/2 = |-1|/2 = 1/2

Answer 33

the period is 0.05

Answer 34

yes.

Answer 35

The amplitude I am not so sure about

Answer 36

the highest point is around 4.5 , right ?

whats the lowest point ?
