Investigate to cell phone plans (koodo v. s. chatr) and determine which one is most cost and user- efficient for my everyday needs. consider questions like: -what options would i like on my phone? ( data, texting, and other applications) -how often i would use my phone? what are the comparisons of the two plans with regard to cost, application, usage, and other important features. what are the algebraic expression to represent the monthly plan for each plan (e. g.,$150-purchases price of phone +$65.60 n)

step-by-step explanation:

most likely the answer is a.

alice wins if a total of 5 is rolled. finn wins if a total of 9 is rolled.

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.
