Answer:
G (3,-4) ; H (8,1)
Step-by-step explanation:
Midpoint formula:
(x₁ + x₂ / 2 , y₁ + y₂ / 2)
For G (Points B and A):
(3 + 3 / 2 , 1 + (-9) / 2)
(6/2 , -8 / 2)
(3,-4)
For H (Points B and C):
(3 + 13 / 2 , 1 + 1 / 2)
(16 / 2 , 2 / 2)
(8,1)
The cost for 9 lbs would be 63 dollars
We'll use the Pythagorean Theorem
130^2 = side^2 +50^2
side ^ 2 = 16,900 -2,500
side ^ 2 = 14,400
side = square root (14,400)
side = 120 feet
