Given:
The equations of parabolas in the options.
To find:
The steepest parabola.
Solution:
We know that, if a parabola is defined as

Then, the greater absolute value of n, the steeper the parabola.
It can be written as


where  , the smaller absolute value of p, the steeper the parabola.
, the smaller absolute value of p, the steeper the parabola.
Now, find the value of |p| for eac equation
For option A, 
For option B, 
For option C, 
For option D, 
Since, the equation is option A has smallest value of |p|, therefore, the equation  represents the steepest parabola.
 represents the steepest parabola.
Hence, the correct option is A.

Answer:
15
Step-by-step explanation:
5/9^-2 = 81/25
3/5^-3 = 125/27
3/5^0 = 1
81/25 x 512/27 x 1 = 15
 
        
                    
             
        
        
        
Answer:
12
Step-by-step explanation:
Length of a circle = circumference = 2πr = 24π
                                             Radius (r) = 24π/2π
                                                              = 12cm
