Han earns $33.00 for babysitting for 4 hours. at this rate, how much will he earn if he babysits for 7 hours? explain your reasoning.

Han will earn $57.75 in 7 hours.

Given the statement " Han earns $33.00 for babysitting for 4 hours".

Hourly rate states rate an employer agrees to pay a worker per hour worked.

The hourly rate = = $ 8.25

so, the hourly rate is $8.25

If he earns $8.25 every hour,

then,

he will earn in 7 hours =

Therefore, Han will earn in 7 hours is, $ 57.75

3 is greater then both of those numbers

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.
