Answer:
The value of cos Ф is ±
Step-by-step explanation:
There are important rules for sin Ф and cos Ф
∵ sin Ф =
∴ sin²Ф =
∴ sin²Ф =
→ By using the third rule above
∵ cos²Ф = 1 - sin²Ф
∴ cos²Ф = 1 -
∴ cos²Ф =
→ Take square root for both sides
∴ cos Ф = ±
∴ The value of cos Ф is ±
Answer:
about $982.20
Step-by-step explanation:
Formula = P(1+I)^T
T =18/12 because its in months not years, so 1.5 years
1+I = 1 + 54/900 or 1.03
P = 900
Plug those in and you get about 982.20
