Determine which of these pairs of vectors are orthogonal 1. u = (5, 0, -4), v = (6, -1, 4)
2. u = 3i - 10j + k, v = 7i + 2j -k
3. u = 6i - 2j - 5k, v = 3i - 2j + 6k
4. u = (2, -8, -7), v = (5, 9, -7)

answer: (-6,3)

step-by-step explanation:

the real question is why is this guys last name heavyfoot

step-by-step explanation:

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
