Determine the period
A sine function is represented as:
Where
By comparing:
and
So:
So, we have:
Hence, the period of the function is 
The answer is 20. The way I do it is divide 12 by 6 then multiply it by 10 (it works as long as the denominator is ten).
You need one equation for the physical nickels and dimes, which total to 21:
n+d=21
Secondly, you need one equation for the numerical value of those nickels and dimes. We know nickels are worth $0.05 and dime are worth $0.10:
.05n+.1d=1.70
Answer:
it would take 4 weeks to buy his computer
Step-by-step explanation:
2 weeks=324
the 50 cents in 2 weeks =100
210+324=523
523$ in 2 weeks
523+324=858
856$ in 4 weeks
add the 4 weeks of 50 cents.
50x4=200=2.00$
2.00+858=860$
tadaaaaaa
