Solve the equation using the multiplication property of equality and the reciprocal of 1 4 . 1 4 ( r − 5 2 ) = 1 8 What is r? r = one-third r = 3 r = two-thirds r = one-half

3

Step-by-step explanation:

1/4(r - 5/2) = 1/8

1/4r - 5/8 = 1/8

1/4r = 1/8 + 5/8

1/4r = 6/8

Divide both sides by 1/4

1/4r ÷ 1/4 = 6/8 ÷ 1/4

1/4r * 4/1 = 6/8 * 4/1

r = 24/8

r = 3

what do you mean by fog

step-by-step explanation:

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.
