What is the image point of (2,7) after a translation left 4 units and up 2 units?
MrRissso [65]

Answer:

Coordinates of the image point → (-2, 9)

Step-by-step explanation:

If a point (x, y) is translated by 'h' units left and 'k' units up then the rule for the translation will be,

(x, y) → (x - h, y + k)

Rule for the translation of a point (2, 7) by shifting 4 units left and 2 units up will be,

(2, 7) → (2 - 4, 7 + 2)

        → (-2, 9)

Coordinates of the image point → (-2, 9)

Draw a triangle with vertices A(0, 4), B(2, -2), and C(-2, -2). Apply a dilation centered at the origin with scale factor to 1/2
Darya [45]
"A dilation centered at the origin with scale factor to 1/2 from the origin" means that we must join O to all the vertices of the triangle, and make the distances 1/2 of the original triangle. This is shown clearly in the picture.

The coordinates of the new triangle are A'(0,4), B'(1,-1), C'(-1,-1).

<span>
The relationship between corresponding sides in terms of their lengths:
The sides of the dilated triangle are half the length of the first triangle.

</span><span>The relationship between corresponding sides in terms of their orientations.
The two triangles have the same orientation.

</span><span>The relationship between corresponding angles in terms of their measures.
The two triangles have congruent corresponding angles.</span>

A cone has volume of 3.
hjlf

Answer:

9/pi or 2.865

2.25/pi or 0.716

9/25pi or 0.115

36/pi or 11.459

Step-by-step explanation:

The formula for the volume of a cone

V= 1/3pir^2h

V= volume

pi= 3.141592...

r= radius

h= height

1) 3= 1/3pi (1)^2h

9=pi(h)

h= 9/pi or 2.865

2) 3= 1/3pi (2)^2h

9=4pih

h= 9/4pi or 0.716

3) 3= 1/3pi (5)^2h

9= 25pih

h= 9/25pi or 0.115

4) 3=1/3pi (1/2)^2h

9= 1/4pih

h= 36/pi or 11/459
