For this discussion, you will investigate population statistics for either any three countries, any three states, or any three cities. (You can probably find the most recent available figures on Wikipedia.) You can choose whichever countries, states or cities you want. Based on those statistics, answer the following questions:
1.Which one has the largest current population?Which one has the smallest?
2.Which one has the largest current rate of population growth, measured as a percent? Which one has the smallest?
3.Will the largest country/state/city always have the largest rate of growth? Why or why not?
4.Using exponential models, make a prediction about the population of your three countries/states/cities in 10 years.

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

don't know what that says sorry i can't you

step-by-step explanation:

idk what it says

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.
