Kristen invests $ 5745 in a bank. The bank 6.5% interest compounded monthly. How long must she leave the money in the bank for i

podryga [215]

Answer:

1. 10.7 years

2. 17.0 years

3. 2nd option

Step-by-step explanation:

Use formula for compounded interest

$A=P\cdot \left(1+\dfrac{r}{n}\right)^{nt},$

where

A is final value, P is initial value, r is interest rate (as decimal), n is number of periods and t is number of years.

In your case,

1. P=$5745, A=2P=$11490, n=12 (compounded monthly), r=0.065 (6.5%) and t is unknown. Then

$11490=5745\cdot \left(1+\dfrac{0.065}{12}\right)^{12t},\\ \\2=(1.0054)^{12t},\\ \\12t=\log_{1.0054}2,\\ \\t=\dfrac{1}{12}\log_ {1.0054}2\approx 10.7\ years.$

2. P=$5745, A=3P=$17235, n=12 (compounded monthly), r=0.065 (6.5%) and t is unknown. Then

$17235=5745\cdot \left(1+\dfrac{0.065}{12}\right)^{12t},$

$3=(1.0054)^{12t},$

$12t=\log_{1.0054}3,$

$t=\dfrac{1}{12}\log_{1.0054}3\approx 17.0\ years.$

3. <u>1 choice:</u> P=$5745, n=12 (compounded monthly), r=0.065 (6.5%), t=5 years and A is unknown. Then

$A=5745\cdot \left(1+\dfrac{0.065}{12}\right)^{12\cdot 5},\\ \\A=5745\cdot (1.0054)^{60}\approx \$7936.39.$

<u>2 choice:</u> P=$5745, n=4 (compounded monthly), r=0.0675 (6.75%), t=5 years and A is unknown. Then

$A=5745\cdot \left(1+\dfrac{0.0675}{4}\right)^{4\cdot 5},\\ \\A=5745\cdot (1.0169)^{20}\approx \$8032.58.$

The best will be 2nd option, because $8032.58>$7936.39

gregori [183]

It can be at least 5.4 feet long since the area of a square is A=s^2. 5.4 times 5.4 is 30

Tina had $47.10 in her bank account on Monday. She withdrew $25 on Monday and also made a deposit of an amount d that she cannot

nalin [4]

The correct answer is a. 47.10 - 25 + d = 97.43.

This is because you have to subtract the $25, because it is a withdrawal, or taking out of money.
This rules out options C and D.

Also, Tina made a deposit of an amount that she can't remember. A deposit is adding a certain amount of money, so you have to +d.

This rules out option B.

The only option left is option A, which makes complete sense.

Which statement best describes Georgia’s Barrier Islands?

NemiM [27]

The statement that best describes Georgia’s Barrier Islands is; A: They protect the coastline during storms.

<h3>What is the correct statement about the place?</h3>

Barrier islands are called “barrier islands” due to the fact that they are good means of creating barrier between the mainland and the ocean.

Now, these barrier islands tend to shelter and protect the mainland from the powerful forces of wind, waves, and other natural disasters. This they do by;

Sheltering the estuaries that form behind the barriers.

Allowing marshes to build up in the quiet waters of the sound.

Filtering of the pollutants that come in from mainland rivers by the marshes.
Providing valuable habitats for water animals and others in that ecosystem.
Serve aesthetic purposes

Barrier islands are a very much valuable resource. Despite the fact that they constantly change and may become badly eroded, they can still rebuild if left alone.

Thus, we can conclude that statement best describes Georgia’s Barrier Islands is that they protect the coastline during storms.
