Determine the vector equation of movement of a plane that is moving in a straight line passing through the point (10, 5, 6) and is parallel to the vector v→ = 12i→+ −34j→+ −6k→. A. r(t) = (10 + −34t, 5 + 12t, 6+ −6t)

B. r(t) = (10 + −34t, 5 + 12t, 6 + −34t)

C. r(t) = (6 + 12t, 5 + −34t, 10 + −6t)

D. r(t) = (10 + 12t, 5 + −34t, 6 + −6t)

D. r(t) = (10 + 12t, 5 + −34t, 6 + −6t)

Hope this helps

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
