) Describe two quick ways to find approximately 33% of 59 books. b) Describe two quick ways to find approximately 25% of $98.50.

c) Describe two quick ways to find approximately 2% of 150 people.
2. How would one perform the EXACT calculations in #1? Describe the process IN WORDS1

3. Quick fractions to percentages:
a) 5 out of 25 is 20 %
b) 20 out of 80 is 25 %
c) 3 out of 298 is 1.01 %
d) 1 out of 1000 is 0.1 %

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.

the weight of the object inside the box!

the answer on ed. is:
