A street that is 116 m long is covered in snow. City workers are using a snowplow to clear the street. A tire on the snowplow has to turn 29 times in traveling the length of the street. What is the diameter of the tire?
Use the value 3.14 for pi. Round your answer to the nearest tenth. Do not round any intermediate steps.

1.3 m

Step-by-step explanation:

116 = 29 × (pi × d)

4 = 3.14 × d

d = 200/157

d = 1.27388535

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.
