Answer:
Use the distance formula to determine the distance between the two points.
Distance
=
√(x2−x1)^2 + (y2−y1)^2
Substitute the actual values of the points into the distance formula.
√ ( (−6) − 0)^2 +( (−3) − 4)^2
Subtract 0 from −6
√(−6)^2 + ( ( −3 ) −4 )^2
Raise −6 to the power of 2
√36 + ( ( −3 ) −4 )^2
Subtract 4 from −3
√36 + ( −7 )^2
Raise −7 to the power of 2
√ 36 + 49
Add 36 and 49
√85
 
        
             
        
        
        
Answer:
5.0 ft-lbf
Step-by-step explanation:
The force is

This force is not a constant force. For a non-constant force, the work done, <em>W</em>, is

with 
 and 
 the initial and final displacements respectively.
From the question, 
 and 
.
Then

Evaluating the indefinite integral,

From the rules of integration,


Returning the limits,

 
        
             
        
        
        
Answer:
0.2 - 0.3 pounds
 Step-by-step explanation:
Well because I dont know much information about the weight and background of the pencils. My answer may not be correct. But the average weight would be around 0.2 - 0.3 lbs.
 
        
             
        
        
        
How can its diagonal be perpendicular to one of its sides? Since this can be read out of your details! You know point A and C are not adjacent but C and D are. So, AC must be the diagonal which is never perp. to any of the sides (CD)
