Ansexponents first. Do all of them. Then combine like terms altogether. Then solve.
Answer:
342:608
Step-by-step explanation:
from the start and end up to the last
2.67 if you round if not you end up with
2.66666666667
I think they’re all rational except for c. because a and b can be turned into fractions and aren’t infinite, but since pi is infinite i think it’s irrational.
To find the account balance for this question you have to use the formula of a compound interest and the formula of the future value of an annuity ordinary.
The formula of a compound interest is
A=p (1+r/k)^kt
A future value?
P present value 3500
R interest rate 0.0065
K compounded quarterly 4
T time 10 years
Also the formula of the future value of an annuity ordinary is
Fv=pmt [(1+r/k)^(kt)-1)÷(r/k)]
Fv future value?
PMT since the payment per year is 2400 so you should find the payment per quarter which is 600 (2400÷4) because the interest is quarterly.
R interest rate 0.0065
K compounded quarterly 4
T time 10 years
The sum of those two formulas is the answer.
The balance is
3,500×(1+0.0065÷4)^(4×10)
+600×(((1+0.0065÷4)^(4
×10)−1)÷(0.0065÷4))
=28,511.25.....answer
