Answer:
8$
Step-by-step explanation:
Answer 1
The formula of the future value of annuity ordinary is
Fv=pmt [(1+r)^(n)-1)÷r]
Solve the formula for n
Fv/pmt=(1+r)^(n)-1)÷r
cross multiplication
(Fv/pmt)×r=(1+r)^(n)-1
(Fv/pmt)×r+1=(1+r)^(n)
take the log for both sides
Log ((Fv/pmt)×r+1)=n×log (1+r)
Divide each side by log (1+r)
N=[Log ((Fv/pmt)×r+1)]÷log (1+r)
Now solve to find n
N=log((10,000÷800)×0.03+1)
÷log(1+0.03)=10.77years round your answer to get 11 years
Answer 2
PMT=81,000÷(((1+0.075÷12)^(12
×19)−1)÷(0.075÷12))
=161.25
Answer 3
PMT=87,000÷(((1+0.054÷12)^(12
×8)−1)÷(0.054÷12))
=726.56
Answer:
n+5 years old
Step-by-step explanation:
Using the current "regular expressions" in use in Java, Perl, and many other applications, this belongs to "character class" using the [ ] notation.
For characters "either" 1,2,3,4, we write
[1234]
or in this particular case,
[1-4]
