Well, if one side is 6cm long, we know there is another side of equal length, or a parallel side. That's 12cm. Then all you have to do is 20 minus 16 (4), and divide by 2. Your answer is 2.

so, the final dimensions of the rectangle are: 6,6,4, and 4

Hope I helped :)

Answer:

  (i) 55.59 km/h

  (ii) 3600 nautical miles ≈ 6670.8 km

  (iii) 30°N 29.3°E

Step-by-step explanation:

(i) The speed in km/h requires a units conversion.

  (30 kt/h)(1.853 km/kt) = 55.59 km/h

__

(ii) Here, we assume we're interested in the <em>distance traveled</em>. If the course is "due east", we presume that means it follows the 30° latitude line, so is not the shortest route between A and B. That is, the distance from A to B will be different from the distance traveled. (The shortest route from A to B is along a great circle.)

  distance = speed × time

  distance = (30 kt/h)(120 h) = 3600 nautical miles

  = (55.59 km/h)(120 h) = 6670.8 km

__

(iii) The radius of the 30° latitude line is ...

  (6370 km)(cos(30°)) = 3185√3 km ≈ 5516.58 km

The relationship between arc length (s) and central angle (α) is ...

  s = rα

So, the change in the vessel's longitude is ...

  α = (6670.8 km)/(5516.58 km) ≈ 1.20923 radians ≈ 69.28°

Then town B has longitude ...

  40°W -69.3° = -29.3°W = 29.3°E

The position of town B is about 30°N 29.3°E.

_____

<em>Additional comment</em>

The route supposedly taken by this sea vessel is from the middle of the North Atlantic to a town in northern Egypt, through the northern Sahara desert. The eastern end point is shown in the attachment.

Some spherical trigonometry is involved if you want to find the end point of the great-circle route of the same length.

Solve for x in the equation x² + 14x + 17 = - 96
gavmur [86]

Answer:

Solutions of x are;

x = -7 + 8i and x = -7 -8i

Step-by-step explanation:

Given the equation: x^2+14x+17 = -96

Add 96 both sides we get;

x^2+14x+17+96 = 0

x^2+14x+113= 0

Using quadratic formula ax^2+bx+c = 0 then the solution is given by:

x = \frac{-b\pm\sqrt{b^2-4ac}}{2a}

On comparing we have;

a= 1,  b =14 and c =113

x = \frac{-14\pm\sqrt{(14)^2-4(1)(113)}}{2(1)}

x = \frac{-14\pm\sqrt{196-452}}{2}

or

x = \frac{-14\pm\sqrt{-256}}{2}

Simplify:

x = \frac{-14\pm 16i}{2} ;  where i is the imaginary, i^2= -1

or

x = -7 \pm 8i

Therefore,  the solution of x are;  x = -7 + 8i and x = -7 -8i

Solve for c.
lorasvet [3.4K]
C = 75
Explanation: to get C alone you would to the inverse operation of 38 which would be subtraction. So subtract 38 from both sides and you get C=75
