40 x 5280 = 211200 feet per hour
211200 / 3600 = 58.666 = 59 feet per second
 
        
             
        
        
        
The fraction of the journey Sapna traveled by car and train is 3/8 and 5/8 respectively.
We know that fraction is an expression in mathematics used to denote the division of two whole numbers.
Given that the total distance = 48 km.
The distance Sapna traveled by car = 18 km.
So, the fraction is = distance traveled by car/total distance = 18/48 = 3/8
The distance Sapna traveled by train = 48 - 18 km = 30 km.
So, the fraction is = distance traveled by train/total distance = 30/48 = 5/8
Therefore the fraction of the journey Sapna traveled by car and train is 3/8 and 5/8 respectively.

Answer:
C
Step-by-step explanation:
The graph can take any value of X
-3[ x^2 - 2x + 1] + 4
-3x^2 +6x -3 + 4
-3x^2 + 6x + 1 
x can take any value of real numbers and there would be a solution
Hence all real numbers is the domain.
 
        
             
        
        
        
Explanation:
Divide the negative 16 by 2= -8 
Then square -8 
So the missing constant is 64
The perfect square would be (x-8)^2
