The points (–2, 4) and (–2, –2) are vertices of a heptagon. Explain how to find the length of the segment formed by these endpoi
Scrat [10]

Answer:

The segment is 6 units long.

Step-by-step explanation:

The points (–2, 4) and (–2, –2) are vertices of a heptagon. We have to explain how to find the length of the segment formed by these endpoints.

If two points at the ends of a straight line PQ are P(x_{1},y_{1}) and Q(x_{2},y_{2}), then the length of the segment PQ will be given by the formula  

\sqrt{(x_{1} - x_{2})^{2} + (y_{1} - y_{2})^{2}}

Now, in our case the two points are (-2,4) and (-2,-2) and the length of the segment will be  

\sqrt{(- 2 - (- 2))^{2} + (4 - (- 2))^{2}} = 6 units. (Answer)

In assaulting a castle wall that is 24 m high, the army must also span a moat that is
Wewaii [24]

Answer:

At-least 30 m

Step-by-step explanation:

Solution:-

- Taking the length of the ladder = L

- The width of the moat surrounding the castle, w = 18 m

- The height of the castle wall, h = 24 m

- To model a situation we will draw a right angle triangle with hypotenuse denoting the Ladder with "L" over the moat against the wall of the castle.

The perpendicular dimension will denote the height " h " of the castle wall.

The base over which the ladder must extend horizontal parallel to moat of width " w ".

- Using pythagorean theorem we can determine the length of the ladder " L ", as follows:

                            L^2 = h^2 + w^2

                            L^2 = 24^2 + 18^2

                            L^2 = 576 + 324

                            L = √900

                            L = 30 m

Answer: The minimum length of the ladder must be 30 m for the enemy to cross over the moat on top of the wall of the castle.
