Given:
Amplitude = 2
Midline = 5
Period of 
.
To find:
The cosine function.
Solution:
The general cosine function is:
...(i)
Where, |A| is amplitude, 
is period, 
is phase shift and D is the mid line.
Period of function is . So,
Substituting 
in (i), we get
Therefore, the required cosine function is .
Step-by-step explanation:
step 1. let's call the balance A, the initial amount P, the yearly rate r, the number of compounds yearly n, and the time t.
step 2. A = P(1 + r/n)^(nt) (compounding equation)
step 3. A = 8500(1 + .0178/12)^((12)(10))
step 4. A = 8500(1.00148334)^120
step 5. A = $10,154.68.
Answer:
$1,860
Step-by-step explanation:
The 20%-35% from up to $6,000 of expenses paid for two or more Qualifying Persons. The percentage falls by 1% for every additional $2,000 of income until it reaches 20%.
22,000+7,000-6,000-15,000=8000/2000= 4%
35%-4%= 31%
31% × $6,000, the maximum qualified child care.
$1,860
