The four functions are reprinted below:
y=-2x +34 y= -10
y=-|3x| y=(x - 2)2
in what order should you stack the machines so that
when 15 is dropped into the first machine, and all
four machines have had their effect, the last
machine's output is -6?
b.
what order will result in a final output of 2 when the
first input is 8?

horizontal translation of 2 units in the positive x direction

followed by

vertical translation of 3 units in the positive y direction

his chances of getting a coin of higher value is 4/19

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.
