For which side length? 10 or 8?
Equate whats inside (arguments) 
with base period of sine function 
and solve for x to get period,
So the period of the graph of the given function is precisely 2.
Hope this helps :)
Given :
A clerk is paid $45.25 per hours for 40 hours a week, 1.50 times the regular rate of overtime and double the rate for a holiday.
To Find :
How much does the clerk get if he works overtime for 5 hours and 2 hours on holidays.
Solution :
Amount from regular job = $ 45.25 × 40 = $1810 .
Amount from overtime = $ (45.25×1.5) × 5 = $339.375 .
Amount from holiday = $ (45.25×2) × 5 = $452.5 .
Total amount clerk will get is :
T = $( 1810 + 339.375 + 452.5 )
T = $2601.875
Hence, this is the required solution.
I guess 84
