Question

HELP! Question A)

Answer 1

could start by saying

min is 5 and max is 55

5+55 divided by 2 = 30
midline at 30

amplitude is 25

Answer 2

okay does that mean the vertical translation is 30?

Answer 3

i think so

Answer 4

if d is your verticle translation ya

Answer 5

okay that makes sense because the c value effects the vertical translation and the it can be found using that formula

Answer 6

do you know how to determine the period or phase shift? @TylerD

Answer 7

c value is phase shift

Answer 8

yes using the equation y=asin(k(x-d))+c

Answer 9

the c value would effect the vertical translation

Answer 10

is that correct?

Answer 11

no it effects the horizontal

Answer 12

aka phase shift

Answer 13

okay how do I determine the period?

Answer 14

period = 2pi/b

Answer 15

so if it starts at 55, then is at 5 at t=7 seconds

Answer 16

that should be half of the period i think.

Answer 17

^^^ correct. Period = 2 * (time between max and the next min)

Answer 18

so we have

14 = 2pi/b then?

Answer 19

so what would the equation look like?

Answer 20

Period = 14 seconds

Period is also 2pi/b. So you can find b.
