The difference between 100 and 75 is 25.
The correct answer will be B
Answer:
(9, 27 )
Step-by-step explanation:
Since the dilatation is centred at the origin, multiply each of the coordinates of the original point by the scale factor of 3
(3, 9 ) → (3(3), 3(9)) → (9, 27 )

and 10.6 is already written as a decimal.
H=(√3)*a/2 = 41.2
So, a=2*41.2/√3=47.6
