Plot the point whose spherical coordinates are given. Then find the rectangular coordinates of the point. (a) (7, π/3, π/6)
(x, y, z) =
(b) (6, π/2, 3π/4)
(x, y, z) =

Labc is reflected across x = 1 and y = -3. what are the coordinates of the reflection image of a after both reflections?

Which line is parallel to the line that passes through the points (2, –5) and (–4, 1) a. y=-x+5 b. y=-2/3x+3 c. y=2/3x-2 d. y=x+5

*let m∠cob = 50°30’, m∠aob = 70° and m∠aoc = 20°30’. could point c be in the interior of ∠aob? why? a. point c could be the interior of aob but it is not the only case b. point c is the interior of aob c. point c is not the interior of aob d. the given is not possible for the plane geometry answer
