A ship leaves port and travels due west for 30 knots, then changes course to S 30° W and travels 50 more knots. Find the bearing

leva [86]

Answer:

232°

Step-by-step explanation:

There are a couple of ways to find the desired direction. Perhaps the most straightforward is to add up the coordinates of the travel vectors.

30∠270° +50∠210° = 30(cos(270°), sin(270°)) +50(cos(210°), sin(210°))

= (0, -30) +(-43.301, -25) = (-43.301, -55)

Then the angle from port is ...

arctan(-55/-43.301) ≈ 231.79° . . . . . . . 3rd quadrant angle

The bearing of the ship from port is about 232°.

<em>Comment on the problem statement</em>

The term "knot" is conventionally used to indicate a measure of speed (nautical mile per hour), not distance. It is derived from the use of a knotted rope to estimate speed. Knots on the rope were typically 47 ft 3 inches apart. As a measure of distance 30 knots is about 1417.5 feet.

5. $34.61

6.$2.93 was saved

7. 3 tulips

8. 12 daffodils

9. 9 tulips

10. 12 daffodils and 15 tulips

theres 2 left. ill let someone else do it

Step-by-step explanation:

3. 4.50*4=18 5.75*3=17.25

18+17.25 -> 35.25*.065=2.29 rounded

4. 35.25+2.29=37.54

5. 35.25-2.75->32.50*.065=2.11 2.11+32.50=34.61

6. 37.54-34.61=2.93

7. 6:8 -> 3:4 ratio -> 3:4

8. 8+4=12

9. 6+3=9

10. 24-12=12 24-9=15

Alexxandr [17]

Answer:

this one is least to greatest -4 -11-2, 1421

Step-by-step explanation:

you have to do the least number to the greatest so a negative number would be least but you can't get confused you have to do the east number.

Find the area of the triangle

Cerrena [4.2K]

Answer:

Part 1) $P=204\ yd$

Part 2) $A=1,325\ yd^2$

Step-by-step explanation:

Part 1)

we know that

The perimeter of triangle is equal to the sum of its length sides

$P=54+97+53=204\ yd$

Part 2)

we know that

The area of triangle is given by the formula

$A=\frac{1}{2}(b)(h)$

we have

$b=53\ yd\\h=50\ yd$

substitute

$A=\frac{1}{2}(53)(50)=1,325\ yd^2$
