at what points does the helix r(t) = sin(t), cos(t), t intersect the sphere x2 y2 z2 = 10? (round your answers to three decimal places. if an answer does not exist, enter dne.)

A, b, c, and d have the coordinates (-8, 1), (-2, 4), (-3, -1), and (-6, 5), respectively. which sentence about the points is true? a. a, b, c, and d lie on the same line. b. and are perpendicular lines. c. and are parallel lines. d. and are intersecting lines but are not perpendicular. e. and are parallel lines.

Check all that apply. f is a function. f is a one-to-one function. c is a function. c is a one-to-one function.
