You deposit $2000 in an account earning 4% interest compounded continuously. How much money will you
bazaltina [42]

Answer:

$3,644.24

Step-by-step explanation:

You are going to want to use the continuous compound interest formula, which is shown below.

A = Pe^{rt}

<em>P = principal amount</em>

<em>r = interest rate (decimal)</em>

<em>t = time (years)</em>

<em />

First change 4% to its decimal form:

4% -> \frac{4}{100} -> 0.04

Next, plug in the values into the equation:

A=2,000e^{0.04(15)}

A=3,644.24

After 15 years, you will have $3,644.24

What is the sum of the integers between the square root of 12 and 40?
satela [25.4K]
1.

the closest perfect squares of 12 are 9 and 16, 

that is 9<12<16

so 
\sqrt{9}\ \textless \  \sqrt{12}\ \textless \  \sqrt{16}

3\ \textless \ \sqrt{12}\ \textless 4

this means, \sqrt{12} is  3 point something...


2.

similarly 

36<40<49

so

\sqrt{36}\ \textless \  \sqrt{40}\ \textless \  \sqrt{49}

6\ \textless \  \sqrt{40}\ \textless \ 7

which means \sqrt{40} is 6 point something...

3. 

<span>the sum of the integers between the square root of 12 and 40 is the sum of 4, 5 and 6, since 4 is the smallest integer after root 12, and 6 the greatest integer to before root of 40.
