What would it cost to put a new carpet in45ft by 20 ft if cost 16.95 per sq yd plus 250 installation charge

$1945

Step-by-step explanation:

Find area that owner wants to install carpet on:

45 × 20 = 900

Convert 900 sq ft to yrd:

900 sq ft = 100 sq yrd

Find the cost for every square yard:

16.95 × 100 = 1695

Add cost with the installation fee:

1695 + 250 = 1945

$1945

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.
