Answer:
FALSE
Step-by-step explanation:
Area of triangle is given by formula :
From picture we see that Altitude = 60 m
Base = 52 + 71 = 123 m
Now plug these values into above formula:
Which is different than given area 1560 m^2.
Hence answer is FALSE.
Answer:
The image of the point (1, -2) under a dilation of 3 is (3, -6).
Step-by-step explanation:
Correct statement is:
<em>What are the coordinates of the image of the point (1, -2) under a dilation of 3 with the origin.</em>
From Linear Algebra we get that dilation of a point with respect to another point is represented by:
(Eq. 1)
Where:
- Reference point with respect to origin, dimensionless.
- Original point with respect to origin, dimensionless.
- Dilation factor, dimensionless.
If we know that ,
and
, then the coordinates of the image of the original point is:
The image of the point (1, -2) under a dilation of 3 is (3, -6).
