Of the 30 girls who tried out for the lacrosse team at euclid middle school,12 were selected. of the 40 boys who tried out, 16 were selected. are the ratios of the number of students on the team to the number of students trying out the same for both boys and girls? how do you know?

chase is right because he already been to the swings and he know how far it will be to get there

step-by-step explanation:

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.
