Sophie invested $92,000 in an account paying an interest rate of 6 1/8% compounded continuously. Damian invested $92,000 in an account paying an interest rate of 6 5/8%
compounded monthly. After 14 years, how much more money would Damian have in
his account than Sophie, to the nearest dollar?

Step-by-step explanation:

The formula we need for each of these calculations is

which is the formula for interest that compounds continuously. We will first figure the amount that Sophie has after that 14 years, then we will figure out the amount that Damian has after 14 years, and then find the difference. Sophie's interest as a decimal is .06125; Damian's is .06625.

and

and

and

Sophie has $216,867.94 after 14 years.

Now for Damian's account:

and

and

and

Damian has $232,592.64 after 14 years.

Damian has 232592.64 - 216867.94 more than Sophie, which is $15,724.70

the quotient is 4x^2 - 27x + 167 with a remainder of -996

step-by-step explanation:

in synthetic division, use -6 as the divisor and use the coefficients {4, -3, 5, 6}:

-6     )   4     -3     5     6

                -24   162 -1002

          4   -27   167   -996

thus, the quotient is 4x^2 - 27x + 167 with a remainder of -996.

note:   your "4x°-3x+5x+6" is ambiguous / incomplete.   i had to assume that you meant '4x^3 - 3x^2 + 5x + 6."

no association

step-by-step explanation:

if you have eyes and you can use them efficiently you can see that it just looks like random dots like do a line of best fit and like they're so spread out it's such a weak association you might as well consider it nonexistent
