Answer:
d = 10s
Step-by-step explanation:
The formula for calculating the speed of Sumi is expressed as;
Speed = distance/time
Given
Speed = 10ft/s
time = s seconds
Required
Distance travelled as a function of time;
from the formula;
Distance = Speed * time
Distance = 10 * s
d = 10s
Hence the equation that expresses the distance d that sumi has traveled as a function of the time s in seconds since she started riding her bike is;
d = 10s

Simply add the numerators of the like fractions together. The denominators remain the same. 
 
        
             
        
        
        
        
 Answer:
Midpoint of AB              = (0 + 2a / 2 , 0 + 0 / 2) = (2a / 2 , 0 / 2) = (a,0)
x coordinate of point c = a 
                                   N = (0 + a / 2 , 0 + b / 2) = (a / 2 , b / 2)
                                   M = ( 2a + a / 2 , 0 + b / 2) = (3a / 2 , b / 2)
                                 MA = √(3a / 2 - 0)² + b / 2 - 0)²
                                        = √(3a / 2 )² + (b / 2) = 9a² / 4 + b² / 4
                                 NB = √(a / 2 - 2a)² + (b / 2 - 0 )²
                                       = √( a / 2 - 4a / 2)² + (b / 2 - 0)²
                                       = √(-3a / 2)² + (b / 2)² = √9a² / 4 + b² / 4

I tried my best hope its correct :0
