Time t (hours) Depth d (m)

0 3.0

1 3.3

2 4.2

3 5.6

4 7.2

5 8.2

6 9.0

7 8.9

8 8.1

9 7.3

10 5.6

11 4.3

12 3.5

13 3.1

Use the regression facilities on your calculator to fit a sine curve to these data. Choose the one option which provides the best fit model (with coefficient rounded to 2 significant figures).

A) t=3.0sin(0.49d-1.6)+6.0

B) d=3.0+6.0sin(0.49t-1.6)

C) t=2.9sin(0.48d-1.5)+6.0

D) d=3.0sin(0.49t-1.6)+6.0

E) d=2.99sin(0.49t-1.60)+6.04

F) d=6.0-3.0sin(0.49t+1.6)

Can anyone help me please. I may be d??

This is not a fair question for this forum.

In order to help you, I would have to have the same programmable graphing calculator as you do, and would have to be familiar with the procedure to use that particular function.

I do not.
