Jim opened an account with $400. the account pays 3 percent quarterly. how much is in the account at the end of 2 years? round to the nearest dollar.
use the compound interest formula, the formula a = p (1 + r/n) ^nt

The money in the account at the end of 2 years is $424.64 .

Step-by-step explanation:

Formula

Where A is the amount , r is the rate of interest in the decimal form , t is the time in years and n is compouding period .

As given

Jim opened an account with $400. The account pays 3 percent quarterly. How much is in the account at the end of 2 years .

p = $400

n = 4

t = 2 years

3% is written in the decimal form

= 0.03

r = 0.03

Put all the values in the formula

A = 400 × 1.0616

A = $424.64

Therefore the money in the account at the end of 2 years is $424.64 .

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.

step-by-step explanation:

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
