Answer:
625 cm3
Step-by-step explanation:
Formula V1 * P1 = V2 * P2
V1 = 450 cm3
P1 = 125 kPa
P2 = 90 kPa
V2 = ?
V2 = (V1 * P1) / P2
V2 = (450 cm3 * 125 kPa) / 90 kPa = 625 cm3
 
        
             
        
        
        
Option A:

Solution:
ABCD and EGFH are two trapezoids.
To determine the correct way to tell the two trapezoids are similar.
Option A: 
AB = GF (side)
BC = FH (side)
CD = HE (side)
DA = EG (side)
So,  is the correct way to complete the statement.
 is the correct way to complete the statement.
Option B: 
In the given image length of AB ≠ EG.
So,  is the not the correct way to complete the statement.
 is the not the correct way to complete the statement.
Option C:  
 
In the given image length of AB ≠ FH.
So,  is the not the correct way to complete the statement.
 is the not the correct way to complete the statement.
Option D:  
 
In the given image length of AB ≠ HE.
So,  is the not the correct way to complete the statement.
 is the not the correct way to complete the statement.
Hence,  is the correct way to complete the statement.
 is the correct way to complete the statement.

Answer:
With a vertex (h, k) at (0, 3) and given that  a = -3, then the equation of this parabola in vertex form is as follows:
     y = a(x - h)2 + k
     y = -3(x - 0)2 + 3
     y = -3x2 + 3
