Answer:
Distance = 7.8 units
Step-by-step explanation:
In coordinate geometry, the distance between the 2 points is given by
where (x1,y1) and (x2,y2) are coordinates of the 2 points.
Above the 2 points given are, (-2,-1) and (3,5).
x1 = -2 , y1 = -1 , x2 = 3, y2 = 5
Distance = 7.8102 units
To the nearest tenth, Distance = 7.8 units
2. An Angle
3. Perpendicular Lines
4. A Plane
Answer:
2) An angle is the correct option.
Step-by-step explanation:
Given : Two rays that intersect at a common endpoint.
To find : Which represents two rays that intersect at a common endpoint.
Solution : We have given
Two rays that intersect at a common endpoint.
Angle : An angle is the space between two lines that meet each other ,When two lines meet at a point.
Therefore, 2) An angle is the correct option.
Answer:
Step-by-step explanation:
Given: The total number of students in a class = 19
Let n represents the number of boys.
Then, According to the question the number of girls = n+5
Now, the equation that most accurately depicts the given word problem will be :-
Hence, the is the equation that most accurately depicts the given word problem .
B. A three-dimensional solid made from a pile of similar two-dimensional circles that grow smaller as the solid gets taller until it reaches a point at the vertex
C. A three-dimensional solid consisting of a base, a point not in the same plane as the base, and all the points between them
D. A three-dimensional solid consisting of two parallel congruent polygons and all the points between them
A cone is best described in the point:
B. A three-dimensional solid made from a pile of similar two-dimensional circles that grow smaller as the solid gets taller until it reaches a point at the vertex.
Three-dimensionalfigures are solid shapes, having three dimensions: length, width, and height.
Some examples of three-dimensionalfigures are cube, cuboid, cone, and cylinder.
We will discuss the description of all the figures given to us, try to know which figure is the description about, and then will tell what is the description of a cone.
A. A three-dimensional solid made from two parallel and congruent discs not in the same plane and all the points between them.
- The description is of a cylinder. A cylinder has both its end as two parallel and congruent discs, which are not on the same plane and include all the points between the discs.
B. A three-dimensional solid made from a pile of similar two-dimensional circles that grow smaller as the solid gets taller until it reaches a point at the vertex.
- The description is of a cone. A cone has a circular base, which grows smaller and smaller to a point.
C. A three-dimensional solid consisting of a base, a point not in the same plane as the base, and all the points between them.
- The description is of a pyramid. A pyramid can have any base, that grows smaller and smaller to a point.
D. A three-dimensional solid consisting of two parallel congruent polygons and all the points between them.
- The description is of a prism. On either end of a prism are two polygonal forms that can be any shape with three or more sides.
∴ A cone is best described in the point:
B. A three-dimensional solid made from a pile of similar two-dimensional circles that grow smaller as the solid gets taller until it reaches a point at the vertex.
