Yes the ratio would change because it needs 3 times more than the original amount so you would multiply it by 3
Answer:
D. 1/3
Step-by-step explanation:
Answer:
a = -1, b = -2.5
Step-by-step explanation:
Rule for the dilation of a vector
by a scale factor of k is,
(x, y) → (kx, ky)
BY using this rule for a vector
by a scale factor of 2.5
→ 
Followed by the rotation by 90° Or
radians,
Rule for rotation of a vector by 90° is,
(x, y) → (-y, x)
By this rule vector
will become,
→ 
If we represent this vector by
,
Then a = -1 and b = -2.5 will be the answer.
