Find the amount necessary to fund the given with drawls. Quarterly withdrawals of $850 for 9 years with an interest rate of 4.4%
Lostsunrise [7]

Answer:

The principal amount necessary to fund is $573.31

Step-by-step explanation:

Given as :

The quarterly withdrawal amount = A = $850

The time period for withdrawals = t = 9 years

The rate of interest = r = 4.4% compounded quarterly

Let The principal amount necessary to fund = $p

Now, <u>From Compound Interest</u>

Amount = Principal × (1+\frac{rate}{100\times 4})^{4\times time}

Or, $850 = p × (1+\frac{r}{100\times 4})^{4\times t}

Or, $850 = p × (1+\frac{4.4}{100\times 4})^{4\times 9}

Or, $850 = p × (1.011)^{36}

Or, $850 = p × 1.4826

∴ p = \frac{850}{1.4826}

i.e p = $573.31

So,The principal amount necessary to fund = p = $573.31  

Hence, The principal amount necessary to fund is $573.31   Answer

If a sequence is defined recursively by f(0)= 3 and f(n + 1)= -f(n) +5 for n ≥ 0, then f(2) is equal to a) 2 b)3 c)5 d)8
jok3333 [9.3K]
Answer: B) 3

-----------------------------------------------------------

f(0) = 3 is the given initial term
f(n+1) = -f(n)+5 is the recursive rule

Plug in n = 0 to find the next term
f(n+1) = -f(n)+5
f(0+1) = -f(0)+5 ... replace every n with 0
f(1) = -3+5 ... replace f(0) with 3
f(1) = 2

The second term is f(1) = 2

Then plug in n = 1 to find the next term after that
f(n+1) = -f(n)+5
f(1+1) = -f(1)+5 ... replace n with 1
f(2) = -2+5 ...... replace f(1) with 2
f(2) = 3

we stop here because we found the value for f(2)
