Answer:(a) BA = (-3,2)   (b) BC = (-9,6)

Step-by-step explanation: (a) Vector BA = position vector of B - position vector of A = vector OB - vector OA = (3-6) i + (4-2) j = -3i+2j [i, j are unit vectors along x and y-axis respectively]. Also vector BA=(-3,2).                     (b) Vector BC = position vector of B - position vector of C = vector OB - vector OC = (3-12) i + (4-(-2)) j = -9i+6j [i, j are unit vectors along x and y-axis respectively]. Also vector BA=(-9,6).

Evaluate bd for a = 5, b = -2, c = 4 and d = -6. user: perform the indicated operation. (-50) �� (-2) user: perform the indicate
Stella [2.4K]
Assuming that the missing operations are multiplication as it is with the first question "bd", then the answer would be as follows:

1.)  Simply substitute the values of b and d before multiplying.

bd = (-2)(-6) = 12

2.) (-50)(-2) = 100

3.) (5/8)(7/12)= 35/96

How do you solve 7.2>0.9(n+8.6)
labwork [276]
7.2>0.9(n+8.6)
multiply 0.9 by all in parentheses

7.2> (0.9*n) + (0.9*8.6)
7.2> 0.9n + 7.74

subtract 7.74 from both sides
-0.54> 0.9n

divide both sides by 0.9
-0.6> n

ANSWER: -0.6> n

Hope this helps! :)
