Aresearcher performs an experiment to test a hypothesis that involves the nutrients niacin and retinol. she feeds one group of laboratory rats a daily diet of precisely 33.65 units of niacin and 38,700 units of retinol. she uses two types of commercial pellet foods. food a contains 0.11 unit of niacin and 195 units of retinol per gram. food b contains 0.38 unit of niacin and 75 units of retinol per gram. how many grams of each food does she feed this group of rats each day?

it has the same slope and a different y-intercept

hope this : )

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.

it goes right

is there any other information given for this problem? this is not enough information.
