Last november there were 620 comma 666 scheduled passenger flights in a certain country, and in november of 1996 there were 651 comma 829. use a percentage to express the relative change. use the second given value as the reference value. also, write a statement describing the result. the relative difference between november of 1996 and last november is what percent

Absolute change refers to the simple difference in the indicator over two periods in time, i.e.

Relative change refers to the absolute change as a percentage of the value of the indicator in the earlier period, i.e.

Now,

Value in Period 1 = 651,829

Value in Period 2 = 620,666.

Then

The ratio between the difference in amounts of passengers to the amount of passengers in November of 1996 is 4.78%.

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.

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
