The average hours of sunlight can be modelled on(adsbygoogle = window.adsbygoogle || []).push({});

[tex]1.5\cos \frac {\pi(x-3)}{26}+6.5[/tex] where x is the number of weeks since the start of the year.

Ok. so it isn't really the calculation questions which are getting me, unfortunately it is just the reading of the model..

Here are the 2 questions i wasn't sure about

b) What is the greatest average number of sunlight per day expected in nelson and when.

c) in which week of the year would you expect the least.

Thanks in advance to thoose who help :)
