Answer:
4 years
Step-by-step explanation:
I = $ 400
R = 5%
P =$ 2000
I = Prt
400 = 2000 *
* t
400 = 20 * 5 * t
400 = 100 t

t = 4 years
Answer:
2.63274768567
Step-by-step explanation:
First, note that 3.1415... is p, so 2(3.1415...) is 2pi and 4(3.1415...) is 4pi.
2pi and 4pi are full rotations, which will lead to the same cosine (i.e. cos(x) = cos (x+2pi) = cos(x+4pi) = ... = cos (x+2k*pi)).
So, the expression equals cos0.5 + cos 0.5 + cos0.5 = 3cos0.5 = 3(0.87758256189) = 2.63274768567
I hope this helps! :)
The answer would be 43.96 for 3.5 hours because for each hour it's 12.56
If you change the fractions into decimals, 5/6=.83, 2/3=.67, 3/4=.75, you can see that 2/3 is the shortest
