a.
To draw:
A segment without measuring device approximately

Answer to Problem 1CR
Solution:
The
Explanation of Solution
Two centimeters is approximately the distance between a joint of the thumb to the tip of the thumb.
So, by using this measurement, draw a segment
Therefore, the segment is
b.
The length of the segment,

Answer to Problem 1CR
Solution:
The length of the given segment to the nearest segment is
Explanation of Solution
With the help of the scale, measure the length of the given segment.
The length of the segment is
Therefore, the length of the given segment to the nearest tenth

- 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.

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.) 1000 ft 180 × ft/s Need Help?
