A person places $6520 in an investment account earning an annual rate of 2.5%, compounded continuously. Using the formula V = Pe
beks73 [17]

Answer:

The amount of money, to the nearest cent, in the account after 3 years will be $ 7028.56

Step-by-step explanation:

The amount is given by

V = Pe^{rt}

Given P = $6520

r = 2.5%

t = 3 years

Substituting the given values, we get -

V = 6520 * e^{2.5*3/100 }\\V = 6520 * 1.078\\V = 7028.56

The amount of money, to the nearest cent, in the account after 3 years will be $ 7028.56

Matthew purchased a washer and dryer for $2,885 using an 18-month deferred payment plan with an interest rate of 26.12%. What is
-Dominant- [34]
For a deferred payment plan no interest is accrued for the deferment period.

If $85 is made each month, then in 18 months, 18 * 85 = $1,530 must have been paid off from the balance owed.

Thus, the remaining balance after the deferment period is $2,885 - $1,530 = $1,355.

Let's plug in x = 2.

f(x) = x^2

f(2) = 2^2 ... replace every x with 2

f(2) = 4

----------

Now plug in x = 3.

f(x) = x^2

f(3) = 3^2 ... replace every x with 3

f(3) = 9

-----------

And x = 5 as well.

f(x) = x^2

f(5) = 5^2 .... replace every x with 5

f(5) = 25

-----------

We see that

f(2)+f(3) = 4+9 = 13

which is not equal to f(5) = 25.

So f(2)+f(3) = f(5) is false.

------------

Another way to phrase why it doesn't work is because (2,3,5) isn't a pythagorean triple. The equation 2^2+3^2 = 5^2 is false.

If it said f(3)+f(4) = f(5), then it would be correct because 3^2+4^2 = 5^2 is a true equation.
