To reach her destination, Jeanette must drive 90 miles. If she drives 5 miles every 7 minutes, how long will it take her to reach her destination? Question 3 options:

2 hours and 10 minutes

2 hours and 2 minutes

2 hours and 6 minutes

2 hours and 12 minutes

2 hours and 15 minutes

2 hours 6 minutes

Step-by-step explanation:

Divide 90 miles by 5 miles

90 ÷ 5 = 18

That is there are 18- 5 mile sections

Each 5 mile section takes 7 minutes , then

18 × 7 = 126 minutes = 2 hours 6 minutes

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.
