Brad had $530.45 in his checking account. He wrote checks for $16.50 and $95.68. He also made a deposit of $19.13. What is the approximate final balance in his account?

437.40

Step-by-step explanation:

a check would be a decrease to his checking account balance so 530.45 minus 16.50 would equal 513.95. 513.95 minus 95.68 equals 418.27. a deposit would be a increase to his balance. 418.27 plus 19.13 would equal 437.40.

$27.5

step-by-step explanation:

$110.00 divided by 4

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.
