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(
) and Q(
), then the length of the segment PQ will be given by the formula
Now, in our case the two points are (-2,4) and (-2,-2) and the length of the segment will be
units. (Answer)
Answer:
Since the prime factor '3' does not form a triplet , hence the given number is not a perfect cube.
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.
