Answer:
(8,-9)
Step-by-step explanation:
using the principle of vectors, you match each number to their coordinates and add them
so we have (7+1,-12+3)
which is equal to (8,-9)
 
        
                    
             
        
        
        
Answer:
You use the formulas for the shapes
Cylinder= 2×π×r×h+2×π×r²               π×r²×h
Cone=  π×r²×
           π×r²×
Square Prism= 2×a²+4×a×h                       a²×h
                             ↑a=base edge
Step-by-step explanation:
                            Surface Area  Volume	
Cylinderical Head  	≈282.74                   ≈314.16  
Conical Hat                     ≈170.13                     ≈78.54
Right Cylinder Torso      ≈471.24                     ≈785.4  	
Right Cylinder Arm         ≈56.55                      ≈25.13
Square Prism Leg           =224                           =192
 
        
             
        
        
        
The x would equal 0 and the y would equal 3
        
             
        
        
        
Answer:
If you know the radius of a circular track, you can use physics to calculate how fast an object needs to move in order to stay in contact with the track without falling when it reaches the top of the loop.
