Question 4. Suppose you need to know an equation of the tangent plane to a
surface S at the point P(2, 1, 3). You don't have an equation for S but you know
that the curves
r1(t) = (2 + 3t, 1 — t², 3 − 4t + t²)
r2(u) = (1 + u², 2u³ − 1, 2u + 1)
both lie on S.
(a) Check that both r₁ and r2 pass through the point P.

Coast Guard Patrol Search Mission The pilot of a Coast Guard patrol aircraft on a search mission had just spotted a disabled fishing trawler and
decided to go in for a closer look. Flying in a straight line at a constant altitude of 1000 ft and at a steady speed of 256 ft/s, the aircraft passed directly over
the trawler. How fast (in ft/s) was the aircraft receding from the trawler when it was 1400 ft from the trawler? (Round your answer to one decimal places.)
