PLEASE AM BEGGINNN YOUUUUU

Vikentia [17]

Answer:

Step-by-step explanation:

A)

A - the population after its decrease

x - the number of years in which there has been a decrease in population

Hence,

$\displaystyle\\A=30000-475x\\A+475x=30000-475x+475x\\A+475x=30000\\A+475x-A=30000-A\\475x=30000-A$

Divide both parts of the equation by 475:

$\displaystyle\\x=\frac{30000-A}{475}$

B)

$\displaystyle\\x=\frac{30000-24300}{475} \\\\x=\frac{5700}{475}\\\\x=\frac{12*475}{475} \\\\x=12\ years$

Certificate of Deposit You want to invest $5000 in a certificate of deposit for 12 months.You are given the options below.which

Genrish500 [490]

Answer:

(a) r = 5.25%,quarterly compounding

Step-by-step explanation:

We are given the following in the question:

P = $5000

t = 12 months = 1 year

The compound interest is given by

$A = P\bigg(1 + \displaystyle\frac{r}{n}\bigg)^{nt}$

where P is the principal, r is the interest rate, t is the time, n is the nature of compound interest and A is the final amount.

When compounded continuously

$A = Pe^{rt}$

where P is the principal, r is the interest rate, t is the time and A is the final amount.

a) r = 5.25%,quarterly compounding

$A = 5000\bigg(1 + \displaystyle\frac{0.0525}{4}\bigg)^{4}\\\\A = \$5,267.71$

b) r = 5%,monthly compounding

$A = 5000\bigg(1 + \displaystyle\frac{0.05}{12}\bigg)^{12}\\\\A = \$5,255.80$

c) r = 4.75%, Continuously compounding

$A = 5000e^{0.0475}\\A = \$5,243.23$

Since, the maximum amount on the principal value is given by r = 5.25%,quarterly compounding
