119. Beatrice decides to deposit $100 per month at the end of every month in a bank with an annual interest rate of 5.5% compoun

sveta [45]

Answer:

Beatrice will accumulate $1230.72 at the end of the year.

Step-by-step explanation:

We can write:

$(1+\frac{0.055}{12})=z$

$100=C$ for deposits

The first month would have only the deposit reflected in her balance, then, expanding some steps of the calculation would yield:

$S_{1}=C\\S_{2}=Cz + C\\S_{3}=Cz^{2}+Cz + C\\S_{n}=Cz^{n-1} +...+Cz+C$

A geometric series is given by:

$1+x+...+x^{m}=\frac{x^{m+1}-1}{x-1}$

Translating our series to the short form:

$S_{n}=C(\frac{z^{n}-1}{z-1} )$

plugin in the values for the 12 month gives:

$S_{12}=100(\frac{(1+\frac{0.055}{12})^{12} -1}{\frac{0.055}{12}})=1230.7169$

If f(1) = 2 and f(n) = f(n − 1)² + 4 then find the value of ƒ (3).

erma4kov [3.2K]

Answer:

f(3) = 68

Step-by-step explanation:

→ f(1) = 2 ⇒ f(2) = f²(2 − 1) + 4

= f²(1) + 4

= 2² + 4

= 8

………………………………………………

→ f(2) = 8 ⇒ f(3) = f²(3 − 1) + 4

= f²(2) + 4

= 8² + 4

= 64 + 4

= 68

The ratio of legs to ears on dogs is 4:2 if there were 20 legs how many ears would there be

liq [111]

$\frac{4}{20}$ = <span> $\frac{2}{e}$

From there you can cross multiply to get rid of the denominators.

4e=2x20
4e=40
e=10

There would be 10 ears.
