Answer:
1200 N
Step-by-step explanation:
Newton's second law:
F = ma
F = (300 kg) (4 m/s²)
F = 1200 N
 
        
             
        
        
        
3-83= 80 
80 divided by 2 is 40 
the answer is 40
        
                    
             
        
        
        
4x-2y=8 ==> y=2x-4 (to better show you what I mean) 
2 lines are parallel if they have the same slope (m the coefficient of x).
So y=mx + b // y =2x-4 means m=2 & y=mx + b, becomes y=2x + b. 
Moreover they are telling us that this function passes by (-2,1), where -2 represents x & 1, represents y. To calculate b , replace x & y by their values:
y=2x+b ==> 1 = 2(- 2) + b==> 1 = -4 + b ==> b= 5. Finally the equation is
y=-2x+5
        
             
        
        
        
(22 x sin(65))/sin(53) =24.96604654 rounded of to nearest tenth = 25 
So X = 25
        
             
        
        
        
A football field is rectangle so each matching side has the same length. Perimeter = adding all sides
