Asimple index of three stocks opens the day with these values: the index rises 3.4% over the course of the day. what is the value of the index at the end of the day? round your answer to the nearest hundred.

The value of the index at the end of the day is $45392.6.

Step-by-step explanation:

Given : A simple index of three stocks opens the day with these values:

[name]  [number of shares] [price per share]

stock x      5000 shares            $4.10

stock Y      2000 shares           $4.50

stock z      4000 shares            $3.60

The index rises 3.4% over the course of the day.

To find : What is the value of the index at the end of the day? Round your answer to the nearest hundred ?

Solution :

Stock values of x,y and z is given by,

Stock x,

Stock y,

Stock z,

The total amount will be

The index rises 3.4% over the course of the day.

The value of the index at the end of the day is

Therefore, the value of the index at the end of the day is $45392.6.

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.
