The question relates to application of sine functions.

------------------

Sunsets are later in the summer than in the winter. For planning a sunset dinner cruise through the 30 000 islands, the cruise planners may find the time, t, in hours (on a 24 hour clock) of the sunset on the nth day of the year using the equation (calculator needs to be in degree mode):

t = 1.75sin0.986(n-80)+18.43

Determine the time of the sunset on Shera's birthday of July 26, the 207th day of the year.

------------

Answer:

7:52 p.m.

-------------

How do I solve this problem?

Do I need to graph the equation or can I just solve it from doing the calculation?

When I substitute 207 in the (n-80) and solve for it, I get 203.75

n = 207 in this case. So the formula becomes

t = 1.75*sin (0.986*127)+18.43

= 1.75 *0.8169 + 18.41

= 19.84 hrs

= 19:50 militsry time = 7:50 PM

Thanks, I just realized what I have done wrong... I forgot to multiple 1.75 with sin

I keep getting 22.25

And before, I had my calculator in radian mode ... now I have it in degree mode
