Eric owns and operates the hot ham food truck. the expression 3.25 b+2
h gives the cost of b burgers and h hot dogs. what is the cost of 4 burgers and 6 hot dogs?

$25

Step-by-step explanation:

The expression 3.25b +2h gives the price for hamburgers and hot dogs purchased together. If 4 burgers and 6 hot dogs were purchased then substitute b = 4 and h= 6.

3.25(4) + 2(6)

13+12 = 25

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.
