Answer the question bellow

A 35 pages per hour

Step-by-step explanation:

The rate of change is the slope

(0,150)  (7,400)

m = (y2-y1)/(x2-x1)

    =(400-150)/(7-0)

    =250/7

    =35.7 pages per hour

Approximately 36 pages per hour

A

Step-by-step explanation:

Rate = slope

(500-150)/(10-0)

= 350/10

= 35

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.

my computer is slow i can not see it sorry
