Answer:

$\sf 500,000,000,000=5 \times 10^{11}$

$\sf 0.00000000005=5 \times 10^{-11}$

Step-by-step explanation:

<u>Scientific notation</u>

$\large\boxed{a \times 10^n}$

where:

$1\leq a < 10$

$n$ is any positive or negative <u>whole number</u>.

To convert a number into scientific notation, <u>move</u> the decimal point to the <u>left or right</u> until there is <u>one digit</u> to the left of the decimal point.

The number of times you have moved the decimal point is $n$ .

If the decimal point has moved to the <u>left</u>, $n$ is positive.
If the decimal point has moved to the <u>right</u>, $n$ is negative.

To convert 500,000,000,000 into scientific notation, move the decimal point <u>11 places to left</u>, so a = 5. As we have moved the decimal point 11 places to the left, the exponent "n" is 11 and is <u>positive</u>.

$\implies \sf 500,000,000,000=5 \times 10^{11}$

To convert 0.00000000005 into scientific notation, move the decimal point <u>11 places to the right</u>, so a = 5. As we have moved the decimal point 11 places to the right , the exponent "n" is 11 and is <u>negative</u>.

$\implies \sf 0.00000000005=5 \times 10^{-11}$

What is the compund interest on 5,000 over 3 years at 5% interest

Katena32 [7]

Answer:

788.13 to the nearest hundredth.

Step-by-step explanation:

Let A be the total amount in the account after 3 years.

The formula is A = P(1 + x/100)^t .

Here P = 5000, x = 5 % and the time t = 3. years.

Amount after 3 years = 5000(1 + 5/100)^3

= 5788.13

So the Interest is 5788.13 - 5000

= 788.13.
