Answer 1

Respuesta:

Explicación paso a paso:

A(-8, 12)

B(1, -2)

C(4, -3)

Tenemos producto escalar entre vectores

A×B = (-8, 12)×(1, -2) = -8 +(-12) = -20

C×B = (4, -3)×(1, -2) = 4 + (6) = 10

A×C = (-8, 12)×(4, -3) = -32 +(-36) = -68

A×B×C = (-8, 12)×(1, -2)×(4, -3) = (-32)+(72) = 104

Answer 2

a) A . B = (-8, 12) . (1, -2)

A . B = (-8) × (1) + (12) × (-2)

A . B = -8 + (-24)

A . B = -32

b) C . B = (4, -3) . (1, -2)

C . B = (4) × (1) + (-3) × (-2)

C . B = 4 + 6

C . B = 10

c) A . C = (-8, 12) . (4, -3)

A . C = (-8) × (4) + (12) × (-3)

A . C = -32 + -36

A . C = -68

d) A . B . C = (-8, 12) . (1, -2) . (4, -3)

A . B . C = (-8) × (1) + (12) × (-2) . (4, -3)

A . B . C = -8 + (-24) . (4, -3)

A . B . C = -32 × 4 + -32 × -3

A . B . C = -128 - 96

A . B . C = -224
