Answer:
ABCD is not a parallelogram
Step-by-step explanation:
Use the distance formula to determine whether ABCD below is a parallelogram. A(-3,2) B(-3,3) C (5,-3) D (-1.-5)
We have to find the length of the sides of the parallelogram using the formula below
= √(x2 - x1)² + (y2 - y1)² when given vertices (x1, y1) and (x2, y2)
For side AB
A(-3,2) B(-3,3)
= √(-3 -(-3))² + (3 -2)²
= √0² + 1²
= √1
= 1 unit
For side BC
B(-3,3) C (5,-3)
= √(5 -(-3))² + (-3 -3)²
= √8² + -6²
= √64 + 36
= √100
= 10 units
For side CD
C (5,-3) D (-1.-5)
= √(-1 - 5)² + (-5 - (-3))²
= √-6² + -2²
= √36 + 4
= √40 units
For sides AD
A(-3,2) D (-1.-5)
= √(-1 - (-3))² + (-5 -2)²
= √(2² + -7²)
= √(4 + 49)
= √53 units
A parallelogram is a quadrilateral with it's opposite sides equal
From the above calculation
Side AB ≠ CD
BC ≠ AD
Therefore, ABCD is not a parallelogram

Answer:
10.44
Step-by-step explanation:
The weighted average cost per unit method seeks to get the cost of goods sold as an average of all cost of goods in the inventory as at the time of sales.
Part of its objective is to strike a balance between the (FIFO and LIFO) inventory valuation methods.
Beginning inventory ( Jan) = 10 units
Cost of beginning inventory per unit = $10
Total cost of beginning inventory = Cost * Number of units
In this case (10*$10) = $100
Additional purchase (Jan 5) = 8 units
Cost of additional purchase per unit = $11
Total cost of additional purchase = 8 * $11 = $88
Weighted average cost per unit at the time 11 units are sold on January 7 = Total cost of units at that time / number of units available at that time.
= ($100+ $88) / (10+8)
= 188/18
=10.44 (approximated to 2 decimal places)
I hope this helps make the concept clear.
