Answer:
The number of calculators is 4871
Step-by-step explanation:
If we integrate dx/dt we get x, which is the number of calculators. To find the number of calculators between the beginning of third week to the end of fourth week (the beginning of fifth week), this integration must be evaluated at t between 3 and 5.

the result of the integration is:
 to be evaluated between 3 and 5, which is:
 to be evaluated between 3 and 5, which is:

 
        
             
        
        
        
Answer:
-3
Step-by-step explanation:
6x - 4 = -22 6x = -18 x = -3
 
        
                    
             
        
        
        
When a fraction corresponds to a repeating decimal, it's denominator is 9 or 99. 
For example, 4/11 = 36/99 = 0.36 with bar notation over 36. 
Example #2: 2/3 = 6/9 = 0.666....
or also written as 0.6 with bar notation over 6. 
You know a fraction responds to a terminating decimal because it can be simplified to a terminating decimal. 
Example: 2/4 = 0.5
        
             
        
        
        
Answer:
(B)
Step-by-step explanation:
Option (B) is in correct order when talking about the specific ones. 
Polygon is the least specific as it can be of many sides.
example: A polygon with 3 sides is a triangle. and the polygon with 4 sides is a quadrilateral.
Hence, quadrilateral is on the second number in least specific group. 
Quadrilaterals with 2 sides parallel and equal are known as parallelogram.
Therefore, they are on the 3rd number in specific group.
Parallelograms with opposite sides parallel and equal and all the vertex angles at right angles are known as rectangles.
Therefore, rectangles are the most specific one in the group. The list is given by (option (B):
1) polygons
2) quadrilaterals
3) parallelograms
4) rectangles.

No, only the value of what you are finding the absolute value of can be a negative. Examples: |-2|=2 |2|=2
