Two points have the coordinates P (6, -3,9) and Q (3, -6, -3). A point R divides line PQ internally in the ratio 1:2. The positi
sweet [91]

(a) i. See comment...

(a) ii. We have

\vec p = 6\,\vec\imath - 3\,\vec\jmath + 9\,\vec k

and

\vec q = 3\,\vec\imath - 6\,\vec\jmath - 3\,\vec k

(b) We can parameterize the line segment from P to Q by the vector function

\vec r(t) = (1-t) \vec p + t \vec q = (6-3t) \, \vec\imath + (-3-3t) \,\vec\jmath + (9-6t) \,\vec k

with 0\le t\le1. The point R is located 1/3 of the way along this line segment, i.e. at t=\frac13, so its position vector is

\vec r\left(\dfrac13\right) = 5\,\vec\imath -4\,\vec\jmath + 7\,\vec k

and hence its coordinates are \boxed{(5,-4,7)}.

Rewrite the following equation in slope-intercept form.<br><br> 3x − 11y = 19
Law Incorporation [45]

Answer:

y = 3/11(x) - 19/11

Step-by-step explanation:

Step 1: Subtract 3x from both sides.

  • 3x-11y-3x=19-3x
  • -11y=-3x+19

Step 2: Divide both sides by -11.

  • -11y/-11=(-3x+19)/-11
  • y=\frac{3}{11}x-\frac{19}{11}

Therefore, the answer is y = 3/11(x) - 19/11.
