Identify the function that best models the given data. 6 | 234
10 | 376
14 | 618
18 | 960
22 | 1402
Possible answers:
W(i) ≈ 234(1.02)x
W(i) = 3.125x2 + 14.5x + 208.5
W(i) = 3.125x2 − 14.5x + 208.5
W(i) ≈ 376(1.04)x

the diameter is 16 cm. are you a teacher?

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.
