Answer:

Step-by-step explanation:



You can read it of the graph which is (1,3) or also calculate it with vectors:
calculate the vector CD:
(5-(-3),2-4)=(8,-2)
to calculate the midpoint you need half of the vector length:
(8,-2)/2=(4,-1)
add the vector to C:
(-3,4)+(4,-1)=(1,3)=midpoint of CD
so it's the third option
Answer:
B.
Step-by-step explanation:
If a shape has a cross section parallel to the base, the cross section will be the same as the base. In the case of a pyramid, it is simply on a smaller scale.
Answer:
2*(100-X)
Step-by-step explanation:
Total length = 100 ft
Total weight =200 pounds
Assuming that the rope has an uniformly distributed weight, its weight per feet is:

If "x" feet have already been lifted, the length left to be lifted is 100 - x.
Therefore, the weight of the remainder of the rope is:
