Solve the problem.
Lorico [155]

Answer:

<h2>560</h2>

Step-by-step explanation:

You must use a combination:

_nC_k=\dfrac{n!}{k!(n-k)!}

We have <em>n = 16</em>, <em>k = 3</em>.

Substitute:

_{16}C_3=\dfrac{16!}{3!(16-3)!}=\dfrac{13!\cdot14\cdot15\cdot16}{2\cdot3\cdot13!}\qquad\text{cancel}\ 13!\\\\=\dfrac{14\cdot15\cdot16}{2\cdot3}=\dfrac{7\cdot5\cdot16}{1}=560

You deposit $5000 in an account earning 3% interest compounded monthly. How much will you have in the account in five years?
rusak2 [61]

Answer:

$5808.08

Step-by-step explanation:

The formula for calculating future value:

FV = P (1 + r/m)^mn

FV = Future value  

P = amount deposited = $5000

R = interest rate  = 0.03  

N = number of years  = 5

m = number of compounding = 12

5000 x (1 + 0.03/12)^60 = $5,808.08
