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:
Step-by-step explanation:
If the two slopes are equal, the lines are parallel. They can't be parallel, because they don't have the same slope
Answer:
Step-by-step explanation:
- 5 + (-3) + 3 is the correct option.
10/-5 = -2 so 5 - (-2)= 7
Answer:
iii. (p - 7)(p - 3)
iv.(x - 8)(x + 4)
Step-by-step explanation:
iii. p² - 10p + 21
= p² - (7 + 3)p + 21
= p² -7p -3p + 21
= p(p - 7) - 3(p - 7)
= (p - 7)(p - 3)
iv. x² - 4x - 32
= x² - (8 - 4)x - 32
= x² - 8x + 4x - 32
= x(x - 8) + 4(x - 8)
= (x - 8)(x + 4)
