The answer:
First: sec(-pi) is sec(pi)
And sec(pi) is -1
Answer:
Step-by-step explanation:
The left hand side of the equation contains proper fractions while the right hand side of the equation contains mixed fraction. The mixed fraction can be changed to improper fraction. 1 2/3 becomes 5/3
To breakdown the left hand side of the equation, we would take lowest common factor of 5 and 15. It is 15
Considering 4/5, if 15 divides 5,the result is 3. Multiplying 3 by 4 gives 12. So it becomes
12/15
Considering 13/15, if 15 divides 15,the result is 1, Multiplying 1 by 13 gives 13. So it becomes
13/15
The equation becomes
(12 + 13)/15 = 5/3
25/15 = 5/3
Simplifying 25/15 to its lowest terms, it becomes 5/3 so
5/3 = 5/3
Then the amount of money will he have in his account after 10 years will be $7,454.16. Then the correct option is B.
<h3>What is compound interest?</h3>
Compound interest is the interest on a loan or deposit calculated based on the initial principal and the accumulated interest from the previous period.
Miguel deposits $5000 in an account earning 4% interest compounded monthly.
Then the amount of money will he have in his account after 10 years will be
We know the compound interest formula.

Where
A = amount
P = principal
r = rate of interest
t = time period (in year)
Then we have
