Answer:
(x, y) ⇒ (-x√3/2 +y/2, -x/2 -y√3/2)
Step-by-step explanation:
The rule for CCW rotation through an angle α is ...
(x, y) ⇒ (x·cos(α) -y·sin(α), x·sin(α) +y·cos(α))
So, for α = 210°, the rule becomes ...
1000
100 times 10 = 1000

4 -1 = 3
to the tenths place, 32.86
Step-by-step explanation: It is because money is always rounded to the tenths place
