Ms. Snow decides that the next test will contain 25 questions and will be worth a total of 90 points. Multiple choice questions are worth 3 points each, and word
problems are worth 4 points each.
Part A. Define two variables to represent the situation. (1 point)
Part B. Write a system of equations to represent the scenario. (1 point)
Part C. How many of each type of question will be on Ms. Snow's test? (2 points)

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.

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.
