Find the accumulated value of an investment of $7000 at 12% compounded semiannually for 12 years.
1 answer:
Answer:
$28,342.54
Step-by-step explanation:
The value of an account earning compound interest is found using the formula ...
A = P(1 +r/n)^(nt)
where P is the principal invested at annual rate r compounded n times per year for t years.
__
You have P=7000, r=0.12, n=2, t=12.
Using these values in the formula, we find the accumulated value of the investment to be ...
A = 7000(1 +0.12/2)^(2·12) = 7000(1.06^24) ≈ 28,342.54
The value after 12 years is $28,342.54.

The number of dogs that are not puppies is 17, the number of adult dogs without long hair is 6, the number of puppy dogs with long hair is 8 and the number of puppy dogs without long hair is 7.
<h3>What is the information missing?</h3>To complete the chart it is necessary to determine:
- Number of dogs that are not puppies.
- Number of puppies with and without long hair
- Number of adult dogs without long hair
Number of dogs that are not puppies:
- 32 (total dogs) - 15 (puppies) = 17 dogs
Adult dogs without long hair:
- 17 (total adult dogs) - 11 (adult dogs with long hair) = 6 dogs
Puppy dogs with and without long hair
Total of puppy dogs = 15, this number can be obtained by adding 9+6 or 7+8. From these combinations, the only one that meets the rule "There are 6 more dogs that have long hair than dogs that do not have long hair" is 8 puppies with long hair and 7 puppies without long hair.
