Korvikt [17]

Answer:

Four (4) pounds

Step-by-step explanation:

Because we required two (2) pounds to stretch the spring eight (8) inches, we need double the force to stretch it sixteen (16) inches. Sixteen is just double the original amount, meaning we need four (4) pounds to stretch the spring sixteen inches.

What is 403,000,000,000,000 in scientific

frozen [14]

Answer:

(A) 4.03 x 10^14

Step-by-step explanation:

403,000,000,000,000

Scientific notation is of the form

a * 10 ^b

where a is a number from 1 to a number less than 10

Put the decimal in the number

403,000,000,000,000.

We need to move the decimal 14 places to the left to get the number to be between 1 and 10

4.03000000000000 so the b is 14

Since we moved it to the left b is positive

We can drop the extra zeros at the end (after the last nonzero digit)

4.03 *10^14

You deposit $2200 Into three separate bank accounts for each pay 3% annual interest. How much interest does each account earn af

Hatshy [7]

The formula to find the amount is

$A=P(1+r)^n$

Here A = amount

P is the principal

r is the rate

n is the number of years

Then to find the interest we subtract principal from amount.

Interest = A - P

Here

P= 2200, r = 3% = 0.03 , n = 6 years

$A = 2200 (1+0.03)^6=2626.92$

Hence the interest earned = 2626.92-2200 = $426.92

Now if the total of $2200 was deposited in three banks then each account earns $\frac{426.92}{3}= 142.31$

Each account earns $142.31
