Find the coordinates of the other endpoint of the segment, given its midpoint M and one
1 answer:
Answer:
The coordinates of the other endpoint are (2b-g,2m-r)
Step-by-step explanation:
Let
R (x,y) ----> the other endpoint of the segment
we have
M(b,m) and Q(g,r)
we know that
The formula to calculate the midpoint between two points is equal to
In this problem the midpoint between Q and R is equal to the point M
substitute
---->
---->
therefore
The coordinates of the other endpoint are (2b-g,2m-r)

The surface area of the three dimensional solid is 72 square centimeters and its three dimensional diagram is attached.
Step-by-step explanation:
The given is,
Detailed view or net diagram of the three dimensional diagram.
Step:1
Three dimensional diagram of the given net diagram is attached.
From the three dimensional diagram given net diagram is rectangular prism.
Step:2
From the three dimensional diagram
Formula for surface area of the rectangular prism,
..............................(1)
Where, w - Width
l - Length
h - Height
From the attachment,
l = 6 cm
w = 2 cm
h = 3 cm
Equation (1) becomes,
= 2 ( 12 + 18 + 6 )
= 2 ( 36 )
A = 72 squared centimeters
( or )
From the net diagram,
Surface area, A = ((6×3)+(2×3)+(2×6)+(2×3)+(3×6)+(2×6))
= 18 + 6 + 12 + 6 + 18 + 12
= 72
Surface area, A = 72 squared centimeters
Result:
The surface area of the three dimensional solid is 72 square centimeters and its three dimensional diagram is attached.
