Answer:
A'B' = 34 units
Step-by-step explanation:
Since the dilatation is centred at the origin , then multiply the coordinates by 2
A' = (2(0), 2(- 7) = (0, - 14 )
B' = (2(8), 2(8) = (16, 16)
Calculate the length using the distance formula
d =
with (x₁, y₁ ) = A'(0, - 14) and (x₂, y₂ ) = B'(16, 16)
d =
=
=
=
= 34
Answer:
equals 22.
Step-by-step explanation:
For every input in a function, there will be one corresponding output. When taking the output of the function and inserting it as the input to the inverse function of the original, the output will be equivalent to the exact input of the original function. In this case, because , that means
will equal 7. Using this knowledge, you can find the value of
, which will be
, so
equals 22.
