Sorry so many im kinda having a hard time haha

3 days

Step-by-step explanation:

He feeds his dog 1 1/2 every day so after 2 days he has fed the dog 3 cups of food and on day three he feeds the dog another 1 1/2 to give you a total of 4 1/2. Or to put is faster 1 1/2 times 3 equals 4 1/2.

what graph

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.
