Answer:
The answer is tan²Ф + 1 = sec²Ф
Step-by-step explanation:
∵ sin²Ф + cos²Ф = 1 ⇒ ÷ cos²Ф both sides
∴ sin²Ф/cos²Ф + cos²Ф/cos²Ф = 1/cos²Ф
∵ sin²Ф/cos²Ф = tan²Ф
∵ 1/cos²Ф = sec²Ф
∴ tan²Ф + 1 = sec²Ф
Answer: x= 7
Step-by-step explanation:
-2x= -14 Divide both sides by -2
x= 7
check
-2(7) = -14
-14 = -14
Step-by-step answer:
Given:
5% annual interest (APR)
compounded daily
Principal = 500
Solution:
Since it is compounded daily, we first calculate the
daily rate = 5% / 365 = 0.05/365
After one year,
future value
= 500 ( 1 + 0.05/365)^365
= 525.634 (to the tenth of a cent)
note: sometimes a year is considered to be rounded to 360 days, or 366 days for a leap year, but there is practically no difference in the results for this problem.
