An initial amount of $600 is invested in a compound
savings account with an annual interest rate of 3.5%.

What is the total amount after 2 years

What is the total amount after 4 years

2 years = $642.74 | 4 years = $688.51

Step-by-step explanation:

To solve this problem, we can use the compound interest formula:

P = initial balance

r = interest rate (decimal)

n = number of times compounded annually

t = time

First, change 3.5% into a decimal:

3.5% -> -> 0.035

Now, lets solve for 2 years:

The last step is to solve for 4 years:

After 2 years, the total amount will be $642.74. After 4 years it will be $688.51

the answer is the third / last answer

step-by-step explanation:

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:
