Olivia and Sadie are both driving along the same highway in two different cars to a stadium in a distant city. At noon, Olivia is 425 miles away from the stadium and
Sadie is 500 miles away from the stadium. Olivia is driving along the highway at a
speed of 25 miles per hour and Sadie is driving at speed of 50 miles per hour. Let O
represent Olivia's distance, in miles, away from the stadium t hours after noon. Let S
represent Sadie's distance, in miles, away from the stadium t hours after noon. Graph
each function and determine whether Olivia or Sadie is closer to the stadium 4 hours
after noon.

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.

i think the answer is d im not sure

1

x = 1

step-by-step explanation:

0 ÷ x = 0

0 ÷ 1 = 0

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
