Answer:
c) 14/5 = 2.8 each (better value)
Step-by-step explanation:
a) 9/3 = 3 each
b) 28/7 = 4 each
c) 14/5 = 2.8 each (better value)
The midpoint is the average of the endpoints.
((-11+i) + (-4+4i))/2 = -15/2 +5/2i
Hi there! :)
Answer:

Use the formula V = 1/3(bh) to solve for the volume of the cone where b = πr² where π ≈ 3.14:
Find the area of the base:
b = π(7)²
b = 49π
b = 153.86 mm²
Find the volume:
V = 1/3(153.86 · 7)
V = 1/3(1077.02)
V = 359.006 ≈ 359.01 mm³.
They are 1, 2 and 3.
Hope that helped ^^
Answer:
(-5/2 , 2)
Step-by-step explanation:
add the two x coordinates of the endpoints and divide by 2. Do the same for the y coordinates.
