Super easy (i hope)
read the questions below. explain your answer using complete sentences. you do not need to show work on or turn in any paper . *
in math class, three students write an expression to model the situation below:
naelli checks her bank account and sees that she has $26,000 in it. she decides to withdraw $1300
per month for rent, groceries, cell phone, and other living expenses.
petra writes:
x= months
1300x + 26000
danielle writes:
m = months
-1300m + 26000
gio writes:
x = months
26000 – 1300x
1. how are the students' expressions the same, how are they different?
2. who is right?
pls give a good explanation and you : )

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.

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
