FOR AN EXAM A new retirement account is just opened. You plan on putting into it an average of $ 425 per month for 40 years at an average yearly rate of return of 7.75%. What are the total value V of this account at the end of the 40 years, the total amount A put into the account over 40 years and the total interest I received in the 40 years?
Possible Answers:
A) V = $ 1,369,389.60, A = $ 204,000.00, I = $ 1,165,389.60
B) V = $ 1,389,389.44, A = $ 204,000.00, I = $ 1,185,389.44
C) V = $ 1,399,389.60, A = $ 204,000.00, I = $ 1,195,389.60

A

Step-by-step explanation: I'm going to be honest though its just a logical guess from some math

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
