Asatellite view of a hurricane is placed on a coordinate plane. the outside edges of the hurricane are located at (4, 6) and (11, 6). solve for the width and the center of the hurricane.

a. width = 4 center = (7.5, 6)
b. width = 4 center = (8, 6)
c. width = 19 center = (5, 8.5)
d. width = 7 center = (7.5, 6)

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.

the answer is d on edge

step-by-step explanation:
