Type the correct answer in the box. The price per gallon of gasoline at a truck stop increases by 21% over the course of a year due to a shortage of oil. The following expression represents the price per gallon of gasoline, in dollars, after t years.

Write an exponential expression in the form (b)c that reveals the monthly rate of increase of the price of gasoline. Round any decimals to the nearest thousandth.

the answer would be c:   ax + b = ax + c

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.
