Answer:
The ladder must be placed at a distance of 33.2 feet from the bottom of the building
Step-by-step explanation:
From what we have here, we are looking at a right angled triangle with the hypotenuse which is the length of the ladder
The height of the child is 50 feet from ground level
So we need to get the third side of the triangle
We can get this by considering the use of Pythagoras’ theorem
This will give us the length of the third side of the triangle
From Pythagoras’ the square of the hypotenuse is equal the sum of the squares of the two other sides
Let the unknown side be x
Thus;
60^2 = 50^2 + x^2
x^2 = 60^2 - 50^2
x^2 = (60-50)(60+50)
x^2 = (10)(110)
x^2 = 1100
x = square root of 1100
x = 33.166
To the nearest tenth, this is 33.2 feet
Answer:Diagram is attached.
Step-by-step explanation:
When a point is rotated about the x axis the new point is at an equal distance from the point of rotation.
The given Urn (red) is rotated along the line x=1 .The rotated points will be at equal distance from the line x=1.In the figure the blue Urn is the rotated figure about the line x=1.
The coordinates of the points are mentioned in the diagram attached .In the rotated figire the y values remains same while for x coordinateis of the point at the same disstane from line x=1 .
Answer:
Step-by-step explanation:
circumference=2πr=6.28
r=6.28/2π=3.14/π=3.14/3.14=1
area=πr^2=π×1²=π=3.14 units²
2.
180 degrees
Clockwise or counterclockwise. Both directions give the same result.
3.
90 degrees
Clockwise.
