You want to be able to withdraw $40,000 each year for 15 years. your account earns 6% interest. a) how much do you need in your account at the beginning? $ b) how much total money will you pull out of the account? $ c) how much of that money is interest? $

a) I need to have $315789.47 in my account at the beginning.

b) A total of $600,000, I will pull out of the account.

c) The total amount of interest that I get is $284210.53.

Step-by-step explanation:

I want to be able to withdraw $40,000 each year for 15 years.

So, in 15 years I will withdraw $(40,000 × 15) = $600,000

Let us assume that I will need in my account $x at the beginning.

If the account earn 6% simple interest, then from the condition given we can write

⇒

⇒ x = $315789.47

Therefore, the interest that I get for 15 years will be $(600,000 - 315789.47) = $284210.53.

a) I need to have $315789.47 in my account at the beginning.

b) A total of $600,000, I will pull out of the account.

c) The total amount of interest that I get is $284210.53. (Answer)

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
