To get to school each morning, Vanessa takes a horse 19.33 19.3319, point, 33 kilometers and a train 2.27 2.272, point, 27 kilometers. In total, the journey takes 26.48 26.4826, point, 48 minutes. How many kilometers is Vanessa's journey in total?

The total distance of Vanessa's journey is 21.6 km

Step-by-step explanation:

The distance Vanessa journeyed by horse = 19.33 km

Distance journeyed by train = 2.27 km

The total time for Vanessa's journey to school each morning = 48 minutes

Therefore, the total distance of Vanessa journey to school is given by the following relation;

Distance to school = The distance Vanessa journeyed by horse + The distance Vanessa  journeyed by train

Distance to school = 19.33 km + 2.27 km = 21.6 km.

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.
