Answer:
see attached diagram
Step-by-step explanation:
A dilation with a scale factor of centered at the origin has a rule:
Then the image of the triangle ABC is triangle DEF(see attached diagram) with coordinates
To find the volume of a triangular pyramid, the formula is:
So we start by finding the area of the base, which is in the shape of a right triangle in this case.
The area of a right triangle is equal to 1/2 x base x height.
We use this area to find the volume.
The volume of the triangular pyramid is 30 cubic feet.
Since EF=FG, you can set 6x - 10 = to 3x + 11
