7. [2/4 Points] DETAILS PREVIOUS ANSWERS SCALCET9 12.5.015. MY NOTES ASK YOUR TEACHER (a) Find symmetric equations for the line that passes through the point (4, -3, 8) and is parallel to the vector (-1, 3, -2). O x+ 4 _ y - 3_ z+8 3 -2 O -(x + 4) = 3(y - 3) = -2(z + 8). O x - 4 _ y+3 _ z-8 -1 3 -2 Ox+4=1+3 Z - 8 3 -2 O -(x - 4) = 3(y + 3) = -2(z - 8). (b) Find the points in which the required line in part (a) intersects the coordinate planes. point of intersection with xy-plane 0,9,0 point of intersection with yz-plane 3,0,6 X point of intersection with xz-plane 0,9,0 X17. [-/1 Points] DETAILS SCALCET9 12.5.046. Find the point at which the line intersects the given plane. x = t - 1, y = 1 + 2t, z = 3 - t; 4x - y + 3z = 9 ( x, y, Z) =19. [1/2 Points] DETAILS PREVIOUS ANSWERS SCALCET9 12.5.052. MY NOTES ASK YOUR TEACHER PRACTIC Determine whether the planes are parallel, perpendicular, or neither. 15x - 3y + 12z = 2, 2y = 10x + 8z parallel perpendicular neither If neither, find the angle between them. (Use degrees and round to one decimal place. If the planes are parallel or perpendicular, enter PARALLEL or PERPENDICULAR, respectively.) 70 X20. [-/1 Points] . DETAILS SCALCET9 12.5.066. MY NOTES ASK YOUR TEACHER Find parametric equations for the line through the point (0, 3, 2) that is perpendicular to the line x = 3 + t, y = 3 - t, z = 3t and intersects this line. (Use the parameter t.) ( x (t ) , y (t ) , z(t ) ) = Need Help? Read It
