How do you write 0.0000248 in scientific notation?
2 answers:
Step-by-step explanation: To write a number in scientific notation, first write a decimal point in the number so that there is only one digit to the left of the decimal point.
In this case, In this case, there is already a decimal point in the number and notice there is only one digit to the left of it.
Now, we need to count the number of places the decimal point would need to move in order to get to a number that is between 1 and 10.
In this case, we would need to move the decimal point 5 places in order to get to the number 2.48 which is a number between 1 and 10.
To get from 2.48 back to 0.0000248, we would need to move the decimal point five places top the left which gives us an exponent of -5. Lastly, we multiply 2.48 by 10 to the -5th power.
Therefore, 0.0000248 can be written in scientific notation as 2.48 x

<h3>What is compound interest?</h3>Compound interest is the interest levied on the interest. The formula for the calculation of compound interest is given as:-
Compound Interest Formula:
A = Account Balance
P = Principle/Initial Amount
r = Rate of Interest (decimal)
n = Number of times compounded (per year)
t = Number of Years
Given Information
Account Balance = ?
It is given that the balance after 15 years in a savings account earns 2% interest compounded bi-monthly when the initial deposit is 1000.
This is because we are gaining money, so the multiplier should be greater than 1. We already added 1, which is 100% so you simply add the 0.02 for the extra 2%.
Number of times compounded per year = 6
This is because it is being compounded bi-monthly, or once every 2 months. 12 months divided by 2 months is 6 months, so 6 times a year.
Number of years = 15
Solve by plugging the given values into the formula.
A = 1000 x (1.14)
A = $1348.07.
Therefore, the amount will be equal to $1348.07. The correct option is A.
