Answer:

The volume of this octahedron is approximately 3.77 cm³.

Step-by-step explanation:

The volume of a regular octahedron is given by the following formula:

Volume = (1/3)*sqrt(2)*a³

Where "a" is the length of each edge. Therefore to solve this problem we have:

Volume = (1/3)*sqrt(2)*(2)³

Volume = (1/3)*sqrt(2)*8

Volume = 3.7712 cm³

The volume of this octahedron is approximately 3.77 cm³.

1 hm=100m

1.5hm=150 meters each tower is from each other.

500km(1000m/1km)=500,000 meters the wire covers.

500,000/150 = 3333.33 towers. Just because we want to be safe and have enough towers we can say we have 3334 towers in the span of 500,000 meters.

B)

1kV=1000V

500kV(1000V/1kV)= 500,000 V

There are 1.2 volts in a AA battery so we divide 500,000/1.2 = 416666.67 times larger

y = x^2 -4x

x = -1

y = (-1)^2 - 4×-1=1+4 = 5

x= 0

y = (0)^2 - 4×0 = 0

x = 1

y = 1^2 -4×1 = 1-4 = -3

x = 2

y = 2^2 -4×2 = 4-8 = -4

x=3

y = 3^2 - 4×3 = 9-12 = -3

x = 4

y = 4^2 - 4×4 = 16 - 16 = 0

now 2nd equation

y = 2x^2 + x

x = -2

y = 2 (-2)^2 + (-2)= 8-2 = 6

x = -1

y = 2 (-1)^2+(-1)= 2-1 = 1

x = 0

y = 2(0)^2 +0 = 0

x = 1

y = 2 (1)^2 + 1 = 3

x = 2

y = 2(2)^2+2= 8 + 2 = 10
