Answer :

1) Which of the following is an example of a dilation?
The correct answer is A) The hearts.

2) If triangle ABC is reflected across line m, the new coordinates will be located at A'(2, -4) B'(7,-7) C'(-2, -7).
The answer is False.

I hope this helps! I can't really see #3. Sorry. But I got #'s 1 & 2 though!
1.) In first question, option 1 is an example of dilation bcuz heart is enlarged. 2.) In second question, reflection should be A( 2,-4) , B(7,-9) and C(-2,-9) so false. 3.) Volume of sphere = 4/3 π r^3 = 4/3 π x ( 27/2)^3 = 10,305.99ft^3. Hence it is true.
