Answer 5

amplitude = (max value - min value)/2

Answer 6

Does the graph I gave you answer problem a?

Answer 7

period is 10

Answer 8

Does the graph I gave you anaswer problem a?

Answer 9

it's just plotting graph ...

Answer 10

So it does answer right?

Answer 11

yes ... just copy that graph and paste it.

Answer 12

Ok, so for question b,

amplitude is 25

Answer 13

Shouldnt period be 14?

Answer 14

One second, I will brb

Answer 15

period is after how many horizontal units does the pattern repeat ... of course it's ten.

Answer 16

Yes 0 - 9

Answer 17

vertical translation = (max value+min value)/2

Answer 18

So VA = 55+5/2 = 30

Answer 19

yeah

Answer 20

horizontal shift is pi/2 left.

Answer 21

try to construct the function from calculated data.

Answer 22

there you go ... phase shift is pi/2
for vertical shift is 5
(2pi/10 (x+5))
I had been confusing with phase shift and horizontal shift.

Answer 23

Hey, what does the rest position mean?

Answer 24

the vertical shift.

Answer 25

is the answer to f 50? 55-5?

Maximum displacement is amplitude that would be 25

Answer 27

Ok. How do I answer the last one?

Answer 28

15 period.

Answer 29

@experimentX , so for answers
b.a
d
and f, is all the same?

Answer 30

3 questinos same answer?

Max height is 55 and min height is 55 – 5 / 2 = 25

Answer 31

*questions

Answer 32

f might be 55 <--- not sure what displacement is

If y is displacement then it is 55
