David and Michael each put the same amount of money in a new bank account. David's account and 4.25% simple interest and he earned $2.40 in interest after one year Michael's account and 6% simple interest how much interest is in her account after one year? round to the nearest dollar or whole number​

$3.00 ($3.39)

Step-by-step explanation:

First, you need to find out how much David and Micheal put in their accounts at first. You know that David accumulated $2.40 at 4.25% interest rate, you can find what 1% of what his original deposit was by dividing $2.40 by 4.25% then multiplying that 1% by 100 to get the original deposit.

(2.40/4.25)100=56.470588235294

$56.47 is how much both David and Micheal deposited originally.

Micheal's account is on a 6% interest rate so you know her earnings should be slightly higher than David's $2.40, near $3.50.

To find the exact earnings you need to find what 6% of $56.47 is,

(56.47/100)6=3.39

So Micheals earned exactly $3.39 but you need to round your answer to the nearest whole number (or dollar) and that would be $3.00      

the slope of the first function is -3. (3/1)

the slope of the second function is 1. (13-10/6-3).

since |-3| is greater than |1|, the function with the steepest slope is the first.

geometric series converge the common ratio r has magnitude less than one.

which is equivalent to

for the example we need

|2-x| < 1

-1 < 2-x   and 2-x < 1

x < 3 and x > 1

we can write that

answer: 1 < x < 3

1a. common ratio r=250/25=10 > 1     diverges

1b.   r=50/100=1/2 converges

when these converge they converge to

where a is the first term.

answer: 200

1c. r=-1   so it's not the case that |r| < 1.     diverges

2a. x is the common ratio so we converge when |x|< 1

2b.   r=-10x / -2 = 5x.

we converge when

|5x| < 1

|x| < 1/5

2c.   r=3-2x

-1 < 3-2x and 3-2x < 1

-4 < -2x and 2 < 2x

x < 2 and 1 < x

1 < x < 2

2d. [/tex] r=-48x^3/12 = 4x^3[/tex]

|4x^3| < 1

|x^3| < \frac 1 4

|x| < 4^{-1/3}
