In training for a swim meet, logan swam 750 meters in 1/3 of an hour. his swimming partner mila, swam 2/3 of logan's distance in 1/4 of an hour. what is milas avarage speed?

2000 m/h

Step-by-step explanation:

speed = distance/time

Mila's distance was (2/3)·(750 m) = 500 m, so her speed was ...

(500 m)/(1/4 h) = 2000 m/h

d

step-by-step explanation:

in a an geometric explicit equation, the first number is the starting rate. in this case 10.

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.
