sketch a graph of the following - At midnight the water at a particular beach is at high tide. At the same time a gauge at the end of a pier reads 10 feet. Low tide is reached at 6 AM when the gauge reads 4ft.

Question

australopithecus · Answer

So you want to graph your independent variable on the x axis and dependent variable on the y axis.

Time is independent of the gauge reading, but the gauge reading is dependent on time.

What exactly do you need help with in this question?

australopithecus · Answer

Are you completely lost or are you stuck on a specific part?

anonymous · Answer

its a translating trig function question and im just wondering how i would graph it but i also need guidance on some other questions related to the statement above

australopithecus · Answer

Ok fair enough well lets write out what you have,

so we have points,  
(12am, 10 feet) <- this is maximum
(6am, 4 feet) <-This is the minimum

The way I would graph this,

|dw:1388454170530:dw|

Would you use sin or cos in this transformation?

anonymous · Answer

cos ?

anonymous · Answer

can you explain the graph a little bit ? please if thats not to much to ask for

australopithecus · Answer

Yes :) cos

anonymous · Answer

because sin always starts at 0 right ?

australopithecus · Answer

because the maximum is at 0 for cos(x)

anonymous · Answer

oh okok and sin is 1 ?
