Answer:
Ratio = 1 : 4
Step-by-step explanation:
Total marbles = 10
Given 1/5 is red, that is 1/5 of the total marbles are red
                                                             
Therefore , 10 - 2 = 8 marbles are blue.
Ratio of red marbles to blue marbles
                                     
 
        
             
        
        
        
He first two are relatively easy. f(x-2) shifts it sideways (2 to the right in this case) f(x) -2 shifts it straight down (by 2)
f(2x) means replace x with 2x in the original 4(2x + 1)^2 − 3 if you factor out the 2 from the square root you get 4*sqr(2) ( x + ½)^2 - 3 which is now in the form a ( x -h)^2 + k the vertex is now at (-½, -3) (it used to be at (-1,-3) the "a" has gotten bigger, which makes the parabola "skinnier" (it goes up faster)
2•f(x) becomes 2*( 4(x + 1)2 − 3 ) = 8 (x+1)^2 -6 where is the vertex now? is this parabola fatter or skinnier than the original f(x) ?
        
             
        
        
        
Rotating 180 degrees about the point p. 
If they are perpendicular reflecting across each one will have the same effect as if the point was rotated 180 degrees about the certain point.

a function of the coefficients of a polynomial equation whose value gives information about the roots of the polynomial.
 
        
                    
             
        
        
        
Answer:
The correct option is D. y = 25 .
.
Step-by-step explanation:
i) From the table and our own observation and a trial and error approach we 
   can clearly see that the equation that matches y in feet ( the distance 
   traveled by the rocket) and x in seconds ( the time elapsed) is given by the 
   equation y = 25
  Therefore the correct option is D. y = 25 .
