If 5 tomatoes cost $2.00, what is the unit price of the tomatoes? how much will a dozen tomatoes cost?

write a ratio that compares the total cost to the number of tomatoes. divide to find the unit price. to find the cost of a dozen tomatoes, multiply the unit price by.
x=
the unit price of the tomatoes, multiply the unit price by .
one dozen tomatoes will cost $.
pls help me fill in the blank, thank you

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.

the answer is  

d.

121π mi^2

hope you got it chief
