Helena has five different flowers. She plans to give one flower to each of her five teachers in any order. She gives the first flower to one of her teachers in the morning.
In how many ways can she give the four remaining flowers to the rest of her teachers in the afternoon?

A. 1
B. 4
C. 21
D. 24

It is 4

Step-by-step explanation:

If you think about it:

1 f

2 F

3 ff

4 FF

Then you could move them along 1

1 FF

2 f

3 F

4 ff

And you could move them down four times.

step-by-step explanation:

the shape,the size and the distance

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.
