Suppose you invest $2000 at annual interest rate of 4.5 % How much money do you have in the account after five years?

nataly862011 [7]

Answer:

Please check the explanation.

Step-by-step explanation:

To find the amount we use the formula:

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

Here:

A = total amount

P = principal or amount of money deposited,

r = annual interest rate

n = number of times compounded per year

t = time in years

Given

P=$2000

r=4.5%

n=4

t = 5 years

Calculating compounded quarterly 

After plugging in the values

$A=2000\left(1+\frac{4.5\%\:}{4}\right)^{4\cdot \:5}$

$A=2000\left(1+\frac{0.045}{4}\right)^{4\cdot \:5}$

$A=2000\cdot \frac{4.045^{20}}{4^{20}}$

$A=\frac{125\cdot \:4.045^{20}}{2^{36}}$

$A = 2,501.50$

Thus, If you deposit $2000 into an account paying 4.5% annual interest compounded quarterly, you will have $2501.50 after five years.

Calculating compounded semi-annually

n = 2

$A=2000\left(1+\frac{4.5\%\:}{2}\right)^{2\cdot \:5}$

$A=2000\left(1+\frac{0.045}{2}\right)^{2\cdot \:5}$

$A=2000\cdot \frac{2.045^{10}}{2^{10}}$

$A = 2,498.41$

Thus, If you deposit $2000 into an account paying 4.5% annual interest compounded semi-annually, you will have $2,498.41 after five years.

Someone please help me

MariettaO [177]

Hey there! I'm happy to help!

Let's think of this as the equation y=mx+b, where m represents the slope and b equals the y-intercept.

The y-intercept is where the line hits the y-axis. As we can see, it hits it at the y-value of zero. Therefore, our equation is just left as y=mx now because b is 0.

We want to find the slope now. This is known as the rise/run, or the y/x. This is basically saying how far up it goes for every one step to the right. If we go to the x-value of one, we see that the y-value is at a little bit less than one. We want to keep on moving to the right until the y-value is at a nice integer value (number without fractions).

If we keep on moving to the right, we see that at the x-value of 3, the y is at 2. This means that the slope is 2/3. And it makes sense! When we were looking at that value of 1, the y-value was less than one and looked like it was at about 2/3, or 0.666....

This will apply to all points on the line. Our y will always be 2/3 of what x is.

Therefore, the equation is y=2/3x

I hope that this helps! Have a wonderful day!

Plz answer mhanifa!

wel

Answer:

I'm not mhanifa, but I am also really good at math (i'm in accelerated math rn) so I will try to help too.

Step-by-step explanation:

My tips:

1. Try to focus on formula's not small things like answers or definitions (they are still important but be more focused on formulas), this will really help you when you need to solve eqautions.

2. Don't over-study. Basically don't overload yourself with information, focus on the major things, if you overload yourself, you may not remember everything, and that would not be very helpful at all.

3. Don't try to study the things you are good at, study the things you struggle with, this will help you ALOT.

4. Take your time, you don't want to mess up because you are rushing, and you know math is really annoying and you can get the answer wrong for one incorrect calculation.

5. Get your sleep, this is very important

I hope this helps!! good luck on your EOG!!!!!!
