Answer: 
Step-by-step explanation:
In the given picture , the line is parallel to the y- axis and passing through (-2,2) and (-2 , -3).
The equation of line parallel to y-axis (has slope undefined) is given by
x= a , where a is the point on x-axis through which the line is passing .
For the given graph , the line is passing through x = -2.
Therefore , the equation of the given line = 
Hence, the correct answer = 
2•(1/4)^(2-1)= 2•(1/4)= 1/2
2•(1/4)^(3-1)= 2• (1/4)^2 = 2•1/16=1/8
Answer:
Step-by-step explanation:
Internal dimensions of the box will be smaller considering the thickness of the wood:
- 21 - 1 = 20 cm
- 11 - 1 = 10 cm
- 7 - 0.5 = 6.5 cm (open top)
<u>The volume is now:</u>
